There I was, in my corner of the basement, my collection of salvaged tin cans sitting in the corner, pondering what I could make... Then a brilliant idea hit me as if I were taking a nap on the train tracks.. I would make a jet engine, from nothing but recycled materials!!

So when I thought about it, having all recycled materials really wasn't possible with my current supplies, while still making it somewhat safe.

EDIT: PLEASE NOTE THIS PROJECT WAS NOT SUCCESFUL, MEANING THE JET I MADE DOES NOT WORK. I HOPE YOU CAN LEARN SOMETHING FROM MY WRITE-UP.

EDIT:
Monday, April 13, 2009: I tested the engine today. I tried to use hydrogen-oxygen gas from my hydrolosys setup and melted part of my fuel system. I will have to do repairs before I can test it again.. I apoligize to everyone who is waiting for a video of it's probable destruction..
Thursday, April 16, 2009: Since last time I purchased a windproof lighter so that I can use the fully combusted butane to run the engine. I held the flame up to the brass tubing, cans, and JB Weld and none of them looked like they were melting. I made a small adapter thing out of spare parts I had lying around so that the lighter could be connected to the fuel input. I had to wait overnight for the JB Weld to dry.. So maybe tommorow, or Saturday..
Monday, April 20, 2009: So my fuel system failed and failed and failed, and melted, and failed again and again.. In an attempt to get something slightly working I went ahead and cut a hole in the side of the main housing and stuck my windproof lighter in to see if I could get it working that way, and the flame went out in less than 10 seconds, I'm not sure why. It was a fun project, and hopefully you can learn from it, and maybe make it work.
A couple improvements I can think of would be:
  • Copper fuel line, instead of brass for a higher melting point
  • Wider diameter fuel line, mine was about 1/16" outer diameter, and even smaller inside, which ended up being way too small
  • make sure that whereever your fuel inputs end up, they have a good amount of clearance from the flametube, during final tests, it was melting from the butane flame..

SAFETY:

This Instructable involves:
  • Cutting stuff
  • Fire
  • Flammable gas
  • JB Weld
  • Sharp Objects
  • Potentially fast moving objects

EDIT: My email recently decided that the instructables robot was spam, so I haven't responded to a lot of comments that I didn't know about. I'm sorry, but I can't do much about it, I tried to fix the problem in my email client..


PLEASE READ THIS INSTRUCTABLE IN ITS ENTIRETY BEFORE BEGINNING TO CONSTRUCT YOUR OWN.
I AM NOT LIABLE FOR ANY RESULTING BAD STUFF THAT OCCURS BECAUSE OF THE INFORMATION PRESENTED HERE.

Step 1: How It Works


Fortunately, I was not without knowledge in my endevor. Being the nerdy teenager that I am, curiosity had spurred me during the late hours of the previous few weeks to discover how exactly we are able to fly. This gnarling curiosity led to a Google search, and many hours of discovering the magic behind what is.. a jet engine

So how does a jet engine work?
As my dramatic narrative of the project mentioned above, I spent a fair amount of time researching how the engine worked out of curiosity. I encourage you to do the same, but I'll try to supply you with enough information to build the jet without doing too much.

STEPS:
  • First, air is sucked, or in our design, fed into the engine, through a fan.
  • The fan pushes the air further into the engine, compressing it further
  • To keep our fuel burning, the air enters the combustion area through what is called a flame tube(also, "flame holder" or "can")
  • The high pressure air and hot exploding fuel, rush towards the exhaust, through another fan, also known as the "turbine" of the engine.
  • The rear fan that is pushed on by the faster-moving gases drives the front fan, causing more air to move into the combustion area, beginning a cycle.

If you do not understand, please take a moment to examine the diagram below, showing the flow of the engine.

I cannot stress enough that you should be intrigued by this engine and want to do your own research on it. Some sources I recommend are here:
http://www.howstuffworks.com/turbine.htm
http://inventors.about.com/library/inventors/blhowajetengineworks.htm
http://www.youtube.com/watch?v=p1TqwAKwMuM

Step 2: Gathering Materials


I looked around me, all materials already at my disposal, waiting to be transformed into something incredible.

The things I used for this project are as follows:
  • An assortment of tin cans
  • A coat hanger
  • Some brass tubing from the local hobby store
  • JB Weld
  • A dremel tool
  • A leatherman multi-tool
  • Sandpaper
  • Electrical tape
  • Rubber Bands

I personally believe that in order to do any project you are forced to innovate. You probably won't have the exact same materials to work with, but use your imagination to pull this off with what you have around you!

The only thing that I don't think you can do this without is the JB Weld, which is why it's bolded above. I used this to attach just about everything together, so I don't think you can go without it.

Step 3: Beginning Construction


It was dark, in the late hours of a school night when I first began to construct my machine. I began dremmeling ever-so precise shapes into the cans. As the cans shrieked and sparked my vision was slowly taking shape into the engine I had imagined. The horrible sound filled my ears and the fumes of teh dissipating metal filled my nostrils. I could feel a fine dust of metal lightly coat my skin as the metal wore away from the can.

The first thing we need to do is form the front, main part of the engine that will house the flametube and the fan shaft. This is the orange section in the diagram. We will refer to this as the "main housing".

To do this I took a peach can, which has a wider diameter than most cans, from what I have seen, and cut a hole in the lid as close to the center as I could get.
I placed the lid near the back of the can to mark a spot for a whole inthe back. The holes will need to be slightly wider than the diameter of your coat hanger. These holes will serve to support our shaft and fans.
I used a ruler to mark an "X" shape on the lid of the can. we will need the front of the engine to be open to allow for air intake. I then cut the triangle-looking piecesformed by the "X" shape out of the lid. This piece will be called the "lid", and we won't need it until the very end.

Step 4: The Flametube


Now I knew I must begin the most vital task: Assembling the flame tube. From my research, I knew this very part would make or break my project, and that it had to be done to the best of my ability.

The next step is to assemble the flametube. If you are reading the dramatic narrative, then you know this is the most important part. This is the purple-ish section in the diagram.

To make this I first selected a can with about a half inch smaller diameter than my peach can.
I then cut a few centimeters off of the top of the can to leave room for the front fan that will go there later. We will refer to this as the "flametube can".
I took the lid from an identical peach can and cut and dremeled until it fit tightly inside my main housing. We will refer to this as the "flametube lid". (This part may be unneccesary for you, depending on what the lid looks like coming out of your can opener.)
Make sure it's a snug fit without getting it stuck, as we will JB weld it in later.
Mark and cut the second lid similar to the first, but make the triangular pieces smaller, to allow the flametube can to be attached to it.
Next align the flametube lid to the back of the flametube can to mark and cut a hole for the fan shaft.
Then align the flametube lid with the front of the flametube can and JB Weld them together.
Rubber band them to keep them aligned and steady and allow to set overnight. The combination of the flametube lid attached to the flametube can will now be referred to just as the "flametube".
Once the JB Weld has set, poke or drill holes along the side of the flametube to let air through.

Step 5: The Exhaust


Having both my main housing and flametube completed, my vision was piecing itself together much more nicely than anticipated. A nearly imperceptible, yet present, flame of excitement sparked within me. I knew my next move was to complete the exhaust.

After what you've gone through so far, this part is really a piece of cake. This is the green part in the diagram.
Fist I selected a can slightly smaller in diameter than the one we used for the flametube. This will be referred to as the "exhaust can".
Next trace the exhaust can onto the back of the main housing. This was pretty easy because it lined up perfectly with the grooves on the bottom of the can.
Draw another circle with a smaller diameter that you will cut along on the bottom of the main housing. We need a smaller diameter than the actual exhaust can so that we have room to JB Weld it.
Use a ruler to draw yet another "X" type shape on the back of the main housing like before. There should already be a hole marked for the shaft to work around.
Cut out the triangular-like pieces on the main housing.
On the exhaust can, draw a circle on the bottom to be cut out. Again, there are awesome grooves to help you. You'll want to keep the resulting disk in tact for the fan shaft later.
Finally, JB Weld the exhaust can to the main housing. This combination will now be referred to as the "housing".

Step 6: The Fuel System


Alas! Every project must be related to fire in some way! This was however, a challenge for me to solve, as the hours of construction quickly dissipated into nothingness. It had to be done, even though it meant I would have to sacrifice the idea of all-recycled to protect my safety.

This part was tricky. I planned to run this off of the butane in disposable lighters, as they're cheap and have a built-in fuel control mechanism, yay!.. Now, it doesn't seem like a very good idea to build any sort of system that is going to be responsible for directing flammable gas out of less-than-reliable recycled items, so I used some brass tubing from the hobby store. I could have used four lighters, and the brass fittings from disposable lighters for fuel injectors, but I wouldn't be able to deliver fuel from each lighter at the same time, light it, and try to get the fan shaft moving, just not enough hands. Your fuel system will depend on what fuel you're actually using, so it could be very different from mine. This part isn't pictured in the diagram, but the red arrows depict where the fuel would enter.
Now for the actual steps, I first bent a piece of brass tubing roughly around the wider part of the housing.
Then, I drilled four equally spaced holes around the main housing, in front of the flame tube.
Next, I drilled four holes in the flametube adjacent to the ones we just drilled on the housing. The holes should be on the flat space between where the air is directed and the side of the housing. This should make more sense if you look at the pictures.
Next, I cut four small pieces of the brass tubing and bent them into a sort of "L" shape and slid them through the holes on the housing, and through the holes on the flametube.
Then, I JB Welded them into place, really globbing it on there to keep everything pressure tight, hopefully. You should let this set overnight.

Good morning sunshine! Since the JB Weld has set up, here's what to do next.
First, we're going to cut some notches in the brass tubing that is bent around the wider part of the housing where the "L" shaped pieces are sticking out. These notches will be a little wider than the outer diameter of the tubing, so that the "L" pieces can stick into them, allowing fuel flow.
Next, align the "L" pieces with the bent piece of brass tubing and secure them loosely with thin strips of electrical tape.
I then used a lighter to melt the tape a little bit, hoping to make it tighter on the tubing, but I don't know if it really helped much.
Then we're going to break out the JB Weld again and REALLY glob it over the joints between the "L" pieces and the bent tubing so that no fuel will leak out.
Let it set overnight, and you may have to patch up some spots tomorrow, and let those set.

(You may be thinking "Jeez, I'm using a ton of this expensive JB Weld!" You're really not, I used a little less than half a tube, and I had a ton of mistakes that I didn't document that used a lot of it)

Step 7: The Fan Shaft


The time had come, the part that I had feared since I began the build: The Fan Shaft. The only part that moves on the whole engine, but yet actually makes it work. a failure here would destroy all that I had done already, and yet, I trudged on.

This part really isn't super difficult. I really knew nothing about aerodynamics, or how an ideal fan would work, so I pretty much made it up as I went along, and made a bunch of mistakes. This is the light blue part in the diagram.

First of all, you should cut out the middle bottom part of your coat hanger that will be used for the shaft if you haven't already.
For the fans, the first thing you need to do is find the small circle that we cut from the bottom of our exhaust, this will be our rear fan.
Use a ruler, and do your best to find the center, mark it, and cut a hole.
Draw a circle round the center hole that will mark how far the blades reach towards the center.
Draw a diameter with your ruler, and continue dividing the sections until you have the amount of blades you desire. Mine has six.
Cut along the lines to make your blades and bend them in one direction, since this is the first one, it doesn't really matter.
Place a little bit of JB Weld where the blade contacts the small circle you drew to reinforce it.
Obtain a can lid slightly smaller in diameter than the diameter of your peach can of the housing, mine was from a tomato sauce can.
Same thing as the rear fan.
Mark and cut the center.
Mark and cut blades, I used a couple more on this front fan.
Bend blades into shape, making sure they are going the same way as your read fan.
Reinforce joints with JB Weld.

After the JB Weld sets on your fans, slide the back fan onto the shaft, the coat hanger and JB Weld it in place.
Slide the shaft through the engine, making sure the back fan isn't caught on anything.
Slide your front fan on the front of the engine, there should be room for about an inch of the shaft to protrude past the front of the engine.
JB Weld your front fan in place.
Let the many JB Welded items set overnight.

Step 8: Touching Up


The fire of excitement that had sparked in me earlier was now roaring with an uncontrollable yearning to run the engine. It looked like it should work, and was calling me to start it and propel myself at high speeds down the pavement, cherishing those strange looks from my neighbors as signs of a job well done. But lo, I wasn't finished yet, and I pressed on evermore through the night.

Now, for the most part the job is done, except for some tweaking. I did spend a ton of time tweaking. Some tweaks I had to do are as follows:
  • Add on the front cap on with electrical tape, I had to be able to move it around a bit, to get my fan to fit in.
  • Bend and trim the front fan so that it would spin freely.
  • Mess around with the fuel system a bunch.
  • Add a small piece of plexiglass to the front of the shaft to keep the shaft in place.

I thought that list would be longer.. Anyway, getting the fans and shaft all spinning freely without catching on anything was the biggest challenge, and took a LONG time.

Step 9: Finishing Up


And now, good people, I bid you adu, for my work here is done. I have delivered to you my story to the best of my ability and now must depart, but I wish you all the best wishes ever.

Alright, yay! We're done. Just as a final word, I'm going to point out again that this project uses nearly all recycled materials. It may not seem like it during the build, but all the major components of the engine are recycled, saving our planet - Yay saving the planet! I actually forgot at points as I was building this that all this stuff would've been wasted. I put a lot of work into this project and hope I provided enough information for some of you to duplicate this.

Ok, three more things that would really make me happy:
1. Comment! I never seem to get many comments when I put things online, either on here or youtube or anywhere else, and I like comments! : )
2. Rate! I often forget to rate things, but it would be nice if you didn't.
3. Vote for me in the Epilog Contest! I'm kind of submitting this late, and I don't really think this is good enough to win, but only if you think it's helpful and informative should you vote for it.

Thanks for reading!

Great! I'm going to put one on my bicycle!
Send me a video.
it will not work because only fuel and air mixture will come out it will not burn
The main reason this will not work is because a jet engine will need a combination of compressor-turbine, if you look at the schematics of a real jet engine you will see that for the type of jet engine you were trying to build you would have needed first to create a compressor using a combination of rotors-stators in a convergent chamber, then you would need to incorporate the fuel delivery system and ignition system after that, then you would need the turbine, in an opposite combination of the compressor, that would be stators first, then rotors, in a divergent chamber, ah, and the turbine needs to have a lower number of rotors-stators than the compressor. you would actually be able to use any fuel, but i would recommend actual hobby airplanes gas... or jet fuel... but u might find that harder to come across... you will need to make the turbine blades-rotors from heat-resistant materials, as well as the combustion chamber, and remember that the objective of the fuel injectors is to make an aerosol out of the fuel, so you would need some sort of pump to deliver the fuel at pressure to create an aerosol at the injectors, this pump, with ingenuity can be driven by the jet engine itself after is started by means of external force (meaning for a small engine a crank or so, and a spark plug or some type of ignitor in the combustion chamber). After u get all that working (which might never happen for you, based on the designs you have made so far...) then u can add an augmenter, which is somewhat shaped like an hour-glass and will take advantage of the "Venturi" effect to increase the airflow the engine is pushing.... There's also the afterburner, but that would be too complicated in your case. the whole idea of the Ecological Jet Engine, made out of recycled materials is quite ridiculous (no pawn intended), sorry to say, but a jet engine burns hydrocarbon based fuels, that's not very ecological, and recycled materials are not fit to resist the high temps in the combustion chamber and turbine. I hope my comment gave you some insight on the real workings of jet engines and drives you to search for more content you can find all over the internet on their designs, (also, there are pulse jet engines, which are much easier to construct and you might actually find it possible to build one with not so much effort) I believe that you have the passion to get one working if you get the right designs and technical knowledge. Good Luck! Morgoth "If you think things can't get worse it's probably only because you lack sufficient imagination."
I appreciate your information. I have researched it much more since writing this Instructable and have found what I did wrong. As I said in the Instructable I did intend to run it off of hydrogen, making it ecological. I have ideas for a second turbine engine, but not enough time and materials..
Yeah, hydrogen is ECOLOGICAL, but is it ECONOMICAL? NO! Try propane. Much safer and easier to come by.
oh how i do not like making comments on old posts, but you are wrong. it can be economical if you make it yourself www.youtube.com/user/01032010814‎- look up his video on how to make fuel from water, its a lot cooler than it sounds.
Hydrogen may not be particularly economical at the moment, but many people are working to change that. The most convincing attempt I have seen involves a genetically modified bacteria or algae, that produces hydrogen. Also, I am currently working on a solar array to directly make hydrogen. However, I believe I mentioned somewhere that at one point I switched to using butane, which is similar to propane.
Yep, I saw abt the hydrogen... not the best idea for jet engines, but I do know it was all in the ecological intent... I don't have much time to get into building one, but as soon as I can find the time I will be making a small jet engine, I will actually have the parts machined from cad designs of my own so they will be up to specs, but the heat resistant materials for the combustion chamber and the blades in the turbine will cost me a pretty penny. maybe i can get away with having them made out of carbon steel and see how long do they last... anyways... If i get anything going i will post, including CADs...
Try starting your next project as a ramjet, it is the same design WITHOUT the fans, and is the simplest jet there is, period. After all, all a jet is is a furnace that vectors its exhaust to produce thrust. Once you have a working ramjet, then you ca get fancy and add fans, making the turbojet you want, but for now, kiss (keep it simple, stupid!) As for all the noise about melting points and not good enough, there is an instructables that makes a working jet/rocket hybrid out of a pickel jar, so dont dissmiss the tin can so quickly. Hope this helps.
I haven't, as I didn't know there was anything called stove glue, but I believe most any fuel will still burn hotter than that..
Well, that's where you may be wrong. A lot of people have copper fuel lines and copper nozzles in their working truck turbocharger jets. Epoxies have a questionable working temp, somewhere between 150 and 300 degrees farenheit. A glue like stove glue is designed to work in extreme temperatures, well in excess of what the metal can do. I would question highly whether the JB&nbsp;weld could hold up to that kind of temperature (which is over 300 degrees for everything aft of the fuel ring.)<br /> <br />
Actually, fuel lines are external to the combustion chamber. Mainly the parts disposed of flames are the combustion chamber itself including the flame holder, the internal fuel injection nozzles and ingnitors, the exhaust the turbine and the housing around them. A usual EGT value is from 500 to 700 in celsius, so for at lest the above parts, you should use materials only that are guaranteed to resist 700 preferably 900&deg;C. I am not sure if foodcans are able to handle that. Also, I don't know what amount of heat the stove glue can take, however if you tell me &quot;up to 1000&deg;C&quot; that means it's probably not safe enough for the critical components.<br><br>fozzy13 got stuck mostly because of erratic design. The very first thing that shows up is that there is no compressor in his build. This is essential to get the fuel burned (and thus the work done). The project would have to meet the following, very minimal, and by no means complete list of requirements:<br><br>- Air gets sucked into the air inlet<br>- Air gets compressed by the compressor (slowing down the flow raises pressure, however under a certain flow-speed-limit, the compressor will &quot;stall&quot;)<br>- Pressurized air (rich in oxygen) gets into the combustion chamber<br>- Fuel gets &quot;sprayed&quot; in the pressurized air<br>- The mixture burns due to the present heat or ignition<br>- Expanding gases exit through the exhaust<br>- Flow from the exhaust of the combustion chamber pass through the turbine<br>- The turbine forces the compressor to continue its rotation<br>- Gases leave the engine (intake must not exceed outlet or flow will stop because of air jam)<br>- All the parts starting from the combustion chamber and its components must me made of a highly heat-resistant material (Preferably the whole engine)<br>- Rotorblades/Fans must be well-balanced
Wow lots of information there! I have been considering starting another attempt at a jet engine soon, but we'll see what kind of time I have. <br> <br>Thanks for the comment!!
OH! I forgot another important warning. Looks like it isn't mentioned in the docs here. Rotating speed of your fans must be restricted under MACH 1, otherwise the parts will break off causing serious damages, injuries or even death. Thus you must keep you fans under (20417.7 / (fan_daimeter_in_meters * 3.14)) RPM for the above security reasons.<br><br>For example if you choose the Cummins ST-50 to make your jet out of, it has a diameter of about 5 inches, so for simplicity, let's say this matches the diameter of the compressor. Then, your diameter is 0.127 meters, so the max RPM should be under 20417.7 / (0.127 * 3.14) RPM, that is 51174.4548 RPM<br><br>Actually the centrifugal compressor of the turbo seems to be resistant to the sound barrier (as people often mention 100000 RPM operations), however a 5 inch axial compressor would possibly &quot;explode&quot; above 51174.4548 RPM<br>This is not mandatory of course, but it is wise to keep in my when experimenting. Supersonic fantips must withstand the extreme conditions...
i m interested with th theories &amp; calculations to design the jet. so can u tell me what do u mean by the above no: 20417.7 ?
To be honest, it was quite a time ago and I don't remember where (or out of what) I've found this value. If I put it simply, you have a 0.127 metres diameter, which in turn gives you a circumference of 0.39878 (around 40cm).<br>This, to reach 340m/s (the speed of sound) needs to have an RPM of 852 so I really don't know. I've abandoned researching this stuff long time ago. My apologies.<br><br>If you would like to build one, buy a turbocharger first and then look around for info on how to attach a combustion chamber to it, give it a fuel and oil supply and always wear some ear protectors.<br><br>Regards
I feel it impotant to warn you: I'm new to this stuff. The things I mentioned above are those I found out till now, and far less than complete. I've even omitted some details in order to keep the comment as short as possible.<br><br>This thread can help you a lot (as driving you through the steps of making a simple home made jet engine):<br>https://www.instructables.com/id/How-to-build-your-own-Jet-Engine/<br><br>Unfortunately the workaround of attaching a shaft to get power out from the engine is not described here, so it is up to you. If you want to simply use the thrust, then this is a complete step-by-step tutorial for you. It works with nearly any fuel of your choice. (I didn't try it because I don't have funds to buy a turbocharger and a welding machine).<br>You can find lots of vids about these jets made out of a turbocharger on youtube. I warn you again: These stuff are extremely loud, so never experiment without a good hear-protection.<br><br>Also check out this one: https://www.instructables.com/id/Design-a-Jet-With-The-Unknown-Basics/<br><br>It's got a lot of important basic information that helps thinking around your project.<br><br>Good luck!
Great effort! But i really don't think it's possible to make a crude jet engine out of tin cans and some metal scraps, you'll never get enough compressions lol. But still very nice design, if you had machined parts you could probably make this work!
did this actually work? a video of it running would be awesome
No, this did not actually work, or else I would have made a video.
this is not gonna work...the problem is the space between blades and the case, the blades shape and the number of blades...as n108bg said, this type of engine work's with high rpm's so it's like a ticking bomb...if you really wanna build this turbine, you should try good materials not food cans. i understand that you're trying to build something complicate, easy, simple and cheap, but it's hard... sorry for my bad writting ;) i'm romanian
Be more imaginative
excuse me?...i don't understand what did you want to say...
Dude u are brilliant and imaginative.dont be discouraged because it did not work.try using an electric motor to keep the blades moving before firing
I built this. I haven't had any luck with it, but the Instructable was in-depth. It looks great and is an awesome conversation starter.
Awesome! Thanks for the comment. Do you have any pictures of the build or finished product??
Ill try to take some
Sorry kid.<br><br>you don't know anything about jets or heat or melting point.<br><br>tin cans? lol. come one. read and learn. try the library for rc books.
It sure looks cool, I can give you that.
Thanks!! Unfortunately thats all it has..
I wonder if tin can blades like yours would work for a turbomolecular pump to create high vacuum? They spin at around 80000RPM though, so balance is of utmost importance.
Hmmm, maybe that would work, but these blades specifically wouldn't work, as they are definately NOT perfectly balanced..
yeah, but they might be a good start with careful detail to precision. I wonder if they could handle the strain from centipetal acceleration? I wouldn't want to be nearby if it failed.
I suppose they may be useful as a first mockup, but other than that I wouldn't want to be near something that fast made from cans that wasn't computer-cut.. And, bearings would be a must..
The explanation was very helpful - i'm probably going to make some kind of a jet engine for my AS tech project
I'm glad it helped you out, if you make anything share it with us!!
Hey, hydrogen isn't a bad idea. With a touch of research, it would make one whallop of an engine. Look at the Continuous Detonation Engine (CDE) or pulse detonation engine (PDE). One other example is the oblique detonation wave engine (ODWE). They run off of the hydrogen/oxygen golden ratio detonation principal to attain theoretical hypersonic speeds of up to mach 5. Granted, rolled tin/steel cans might not be the best choice of materials for this, but you have one hell of an idea rolling here. Nice job.
Thanks! I'll definately try to look into those
Come on morgoth_lord give him a chance, all what has been invented is for 2 reasons WAR or ACCIDENT , fozzy13 keep it up, just do a little more research, and u will come up with an improve
I think part of the problem is you might need something to start the fan blades spinning. In an aircraft jet engine they don't simply light the fuel and let it go, they &quot;spin up&quot; the engines first (father is an airline pilot). If you get the blades spinning first before you add ignition it might work better. Even blowing compressed air through the intake might get them spinning.
Compressed air was blown through the engine when I was trying to start it.
oh, ok. It didn't say it, so that's why I mentioned it. how fast did it make the blades spin?
Fair enough, I thought I had included it somewhere. I have no idea how fast the blades were spinning, only that they were screeching like a turbine should when I really got it going.
okey dokey
Try building a jet engine like this maybe year ago. Ill do it again when i have time. Im thinking axe cans for fuel. Those things burn nice.
Gasoline works surprisingly well, but jet fuel would be the absolute best.<br />
Jet Dragsters and Jet Funny Cars usually run K1 kerosene. It's a lot cheaper than Jet fuel and really easy to get.<br />
Kerosene is basically jet fuel
True... but Jet A has additives and other stuff that K1 doesn't, and you can walk to most gas stations and buy K1 and put it in a can. Whereas Jet A you gotta go to an Airport that sells Jet A and they usually frown on putting it in a can. Plus I'm sure trying to leave an airport with a can of Jet A would raise some eyebrows at Homeland Security.
