Step 9: Plumbing the fuel and oil systems

Now that you have the flame tube drilled, open the combustor housing and insert it between the rings until it snugs down into the back against the exhaust cap. Replace the injector side cap and tighten the bolts. I like to use hex head cap bolts just for the look of them, but the convenience is also nice as you dont have to fidle with a regular wrench.

Now you will need to get some fuel to the system, and some oil to the bearings. This part is not as complicated as it may first seem. For the fuel side you will need a pump capable of high pressure and a flow of at least 20 gallons per hour. For the oil side of things you will need a pump capable of at least 50 psi pressure with a flow of about 2-3 gallons per minute. Fortunately, the same type of pump can be used for both. My suggestion is the Shurflo pump model number 8000-643-236. Other alternatives are power steering pumps, furnace pumps, and automotive fuel pumps. The best price I have found on the Shurflo is from http://www.dultmeier.com and is currently $77 US. Do not skimp out and buy the other Shurflo pumps which look the same but are cheaper. The valves and seals in the pumps will not work with petroleum based products and I can not guarantee that you will have much luck with them.

I have provided a diagram for the fuel system, and the oil system for the turbo will work the same way. If your pump does not have a bypass return directly on it (the Shurflow does not, but some furnace pumps do) then you can omit the pump bypass as it is only there to catch blowby from the pump itself.

The idea of the plumbing systems is to regulate pressure with a bypass valve setup. The pumps will always have a full flow with this method, and any unused fluid will be returned to its holding tank. By going this route, you will avoid back pressure on the pump and the pumps will last longer too. The system will work equally well for fuel and oil systems. For the oil system you will need to have a filter and an oil cooler, both of which would go in line after the pump, but before the bypass valve.

For an oil cooler, I suggest B&M transission coolers. Oil filters can be the regular screw on type by using a remote oil filter mount. Make sure that all lines running to the turbo are made of "hard line" such as copper tubing with compression fittings. Flexible line such as rubber can blow off and end in disaster. Oil or fuel hitting a hot turbine housing will burst into flame very quickly. Also of note is the pressure involved in these pump systems. Rubber hose will soften with heat, and the high pressures from the pumps will cause the lines to rupture and slip off of fittings. Be safe and use hard lines. It is just as inexpensive as flexible lines. YOU HAVE BEEN WARNED OF THE DANGERS, SO I ACCEPT NO LIABILITY FOR YOU UNWILLINGNESS TO FOLLOW INSTRUCTIONS!

When plumbing the oil lines to the turbo, make sure that your oil inlet is on the top of the turbo, and the drain is at the bottom. The inlet is usually the smaller of the two openings. If you are using a water cooled turbo it is not neccesary to use the water jacket at all, and nothing need be hooked to these ports. It will only be useful if you would like to supply a flow of water for cooling the turbo upon shutdown.

Tanks for fuel can be any size, and oil tanks should be capable of holding at least one gallon. Do not place the pick up lines near the return lines in tanks, or the aeration caused by the returning fluids will casue air bubbles to get in the pick up lines and the pumps will cavitate and lose pressure!

For fuel injectors, I recomend HAGO nozzles from McMaster Carr http://www.mcmaster.com Look on page 1939 of the online catalog for the water misting nozzles in stainless steel. An engine of this size will need a flow of approximately 14 gallons per hour at full bore.

For my oil system I use Castrol fully synthetic 5w20 right now. A fully synthetic oil with a low viscosity is a must. The fully synthetic will have a much higher flash point and be less likely to ignite, and the low viscosity will help the turbine to get started rotating easier.

For more information about calculating fuel requirements and such, I suggest you join a user group such as the Yahoo Forums "DIYgasturbines" user group. There is a wealth of information there, and I am a regular member.

Ahh, you will need a source of ignition! Since there are numerous ways to get a spark from a sparkplug I will not even try to go too in depth. I leave it to you to search the internet for a nice high voltage circuit to get a spark, or you can cheap out and wire an automotive flasher relay to a coil and get a rather slow, but usable spark out of your plug.

For the power to all of the 12 volt systems, I like to use 12 volt 7 or 12 amp hour sealed gel cell batteries such as are used in burglar alarms and battery back ups. They are small, light, and well suited to the task, plus they fit easily on a jet kart or other small vehicle.

Ok, so you've made it this far. All you need now is a stand on which to mount your engine. You can see the test stand I made in other pictures here and get an idea of how to make one for yourself. Do you have your leaf blower ready? Ok, lets get it started!
<p>well, i have some ideals on a jet engine design, use kerosene, it must have atleast 30 to 1 compression ratio for fuel to ignight. a kind of impeller on one side and a compression chamber on the oposite side, the turbine drive shaft would be attached to a starter/generator. exhaust into thrust. the faster it turns the greater pressure for combustion, i will have to build a working model.. jet engines use atmosphereic air vrs rocket engine carries its own oxigen</p>
I also had another question. You mention using jet fuel liquids. Would using gasoline be a bad thing? Would liquid propane work? Or natural gas? I do not want to start a debate about a hydrogen generator so I will not even add that.

This might be a stupid question (they're really are stupid questions) where does the exhaust go when it's in the motorcycle frame?
After sending that comment I realized that I used the wrong they're. I meant to use there. I appologize to the whole of the Internet.
Anything is possible after all you say one is available for 40k. <br>Possible by you and me? Seriously doubtful. Now while its not fair for me to judge your skills and resources, theres an old adage... (If you have to ask).<br>I did a Google search for &quot; turbine powered glider &quot; and then selected images. There is a lot of slick stuff out there. It seems there are quite a few 2 and 3 model turbines being used as sustainer's. My suggestion of using 4 might be over-kill, but as stated earlier it sure would look cool. What I see in my minds eye is something like the De Havilland Comet, only a glider profile.
<p>Nozzles start on page 2084 now.</p>
<p>I am F.Russell Grice i like to try my Grice-Device Fuel-Expander on a turbine engine to see how many more MPG it get them? A auto gets 5 to 16 more MPG look scnow.comgricedevice read Grice-Device can help streatch miles per gallon?</p>
<p>Curious about the weight to thrust ration? Wondering if a small light weight version could be made safe enough to fit inside a 800 lb glider and used as a sustainer engine.</p>
<p>You might look into model aircraft turbines. There a bit pricey at <br>2500.00 per engine new, and only about 15lbs of thrust so you will need <br>at least 4 engines to work as &quot;sustainer engines&quot;. This would give <br>60lbs thrust. Still kinda light but If my memory serves me correctly <br>gliders have a 20:1 or better glide ratio (I think). 40 to 60 - <br>Wikipedia. So 4 engines should work pretty good as a sustainer. And all <br> for a mere 10,000.00. Rest assured you would have the slickest <br>personal glider on earth. I would duct them with two in each wing if <br>possible as they are only about 6&quot; in diameter. If you build it I want a <br> photo.</p>
Glider manufactures build one today, single sustainer, 40 lbs and it mounts into the fusilage behind the seat pilot seat, at near center of gravity. At the press of a button a hatch opens, the sustainer appears and you start engine, works in reverse also. I was wondering if this might be a possible build. You can buy it for $40k.
<p>Your own personal U2...</p>
<p>Excuse me but the web site: http://icdn4.digitaltrends.com/image/2015-mercedes-benz-gla45-amg-rear-spoiler-2-1500x1000.jpg-- does NOT belong in my writings. I was trying to cut n paste. and it did NOT cut, but it pasted a photo of a Mercedes AMG. Sorry</p>
<p>Sorry for the misplaced reply comment. The comment about the sustainer's was meant for someone else.</p>

Never gonna work unless you start at the beginning. <br><br>Now build a miniure arc reactor and have someone drill a hugehole in your sternum so you can mount it. For sake of ease just rout the interface wiring just route the wires out down below.<br><br>Go ahead an start building your suit, by the time you are ready to power it there should be a viable engine of some kind. Lol<br><br>Do not attempt any of the suggestions in this message as they are probably dangerous and were meant as humor. I know not too good huh?<br><br>Anyway, cheers all
<p>okay i know this sounds stupid but im wanting to make a real working ironman suit but i need to know how to make to turbine small enough to fit the hand and feet so my suit can fly. i need some help. more or less hands on help.</p>
<p>Sorry to say, but you'll never be able to make it actually fly (for a couple of reasons). First off, if you make the turbines small enough to fit in your palm (literally), then they would not have nearly enough power to lift you off the ground. Second, Jet Engines produce huge amounts of heat, and so you would have singed hands if you ever tried. Also, Jet Engines need a large amount of air traveling (more or less) in a linear direction, so unless you have a large hole in your hand to allow air to enter the turbines, you would have a lot of trouble pumping through enough air. Lastly, unlike in the movies, controlling flight with the center of thrust(s) being the ends of your limbs is really difficult. Really cool idea though :)</p>
<p>This is actually wrong, anything is possible. The trick is having he lines stronge enoguh to support the pressure. As long as lift exceeds weight yo have flight. With .1% of atmospheric change you get 212 lbs of lift. Do with as you will!</p>
<p>Listen, I work on an aircraft that has one VERY large augmented jet engine (F110-GE-100), with a maximum thrust of 28,000 lbs and a dry weight of roughly 4,000 lbs (no fuel). 28,000/4,000 = 7. That is a Thrust to weight ratio of 7:1. For the purposes of math, the average (looks like most of us are men) male weighs ~180lbs plus the weight of the suit, lets say at least 80 lbs. Therefore (180 + 80 = 260) lbs / 7 = ~37 lbs for the engine running at MAX not factoring in the weight of the engine in the suit, the thrust necessary to sustain flight with fuel onboard or protective equipment given that the turbine inlet temperature can hit 1510 degrees Celsius. Using the same ratio applied to my jet. This engine will consume ~78 lbs of fuel per 1 flying hour (NOT AUGMENTED/NO BURNER) (78/6.7=11.6G*3.62(for FY2014)=$42/hr). The added weight of fuel will bump your engine size up to roughly 48 lbs (for 1 hr flight time). And thus, you will be putting a 180lbs man in a 80(suit)+48(eng)+78(fuel&lt;1hr)=206lbs for the whole suit minus the pilot, safety equipment, the ACTUAL size of the engine given that I got lazy with my math earlier, and no flight controls (fly straight until you hit something). There is much more but you get the picture. The total weight with all of these things would weigh ~300-350lbs, which makes it impractical given that the pilot probably cannot hold it up. </p><p>All that being said, you would be better off using an external combustion engine (chemical rocket engine), or you could do humanity a HUGE solid and start researching/developing a more efficient hall effect thruster. But please, for your's and everyone else's safety, please don't actually try to make an Iron Man suit. Failure to comply may result in injury or death to personnel.</p>
<p>You should be more worried about him succeeding. Injury and death by accidents is a hell of a lot better than knowing there's a walking flying death machine that can go anywhere and destroy anything. </p>
Yeah and if you dropspit on the floor screen, before you caraformer acetate you can go back in time.
<p>idk if you could fly, but there are lots of people who have built Iron Man's blaster thingies</p>
Use plasma engines
<p>Watch this:</p><p>https://www.youtube.com/watch?v=Czy0pXRRZcs</p>
Im pretty sure iron man doesnt yse simple turbine engines for his advance suit,one if the engines where that small it would not work and two in the movie he has flew in space and water.
<p>It's not real... It's a movie. Special effects, photoshop, cgi...</p><p>Gesh, next people will think the cgi effects used by Nasa for the planets and all are reall on the spot photos...</p>
I can see no advantage of having thrusters mounted in the hands and feet; it would make the hands of the suit clumsy and not very good at other tasks. It would also be impossible to control. Central on the back is the best place for a thruster, out of the way.
<p>Based on the reply from the aircraft guy, I would suggest you add a hook to the back of the suit and using relatively invisible line, simply hoist the man in the suit into the air for your YouTube Video. You can use software to edit out the lines just like they do in the movies. Iron man really doesn't fly its done with greenscreen and cables with very good editing.</p><p>Get some fireworks to create the illusion of rocket power and there you go. Up, up in the air. Its Iron man....</p>
I don't think it is stupid and not possible. And, it doesn't have to be the same as the movies. It needs a lot of knowledge and enthusiasm. I don't have too much aerodynamic knowledge but I could join you if u r serious.
<p>Because it IS stupid. No one has built a homemade Iron Man or Rocketeer jet pack because it won't work. Go ahead and kill yourself or just go back to the bedroom in your mom's house and read your comic books.</p>
Hay how could you that,you at flight noww, but have you made repulsor,radiator,arc reactor and i think its not possible!!!!!! If it is possibe so plz mail me pics at ktarun811@gmail.com<br>I will be wating
I've been wondering if a &quot;quad&quot; type thing can be made with jet engines
<p>This thing is so far beyond the capability of 99.99% of instructable-types (including me). But I just love reading creative &quot;logic&quot; especially when it seems so Rube Golberg-ish. Colossal entrainment! Thanks!</p>
<p>Oh my good LORD !! Wouldn't it be totally awesome if we ALL had jet turbine engines? They run on practically anything combustible (like the Chrysler gas turbine of 1965//Leno's got one.) No phttp://icdn4.digitaltrends.com/image/2015-mercedes-benz-gla45-amg-rear-spoiler-2-1500x1000.jpgistons, rods, crank, rings, camshaft, lifters pushrods, rocker arms, valve springs, valves oil seals NONE OF THAT. A simple gas turbine and NO it's NOT THE MAZDAAAAH Wankel either. Check out the sites--wow!</p>
<p>There is a guy who built what has to be the most intricate turbo jet engine. His site is www.rcdon.com. Check it out if you are looking to build one of these.</p>
<p>These incidents modern machine needs a skilled engineer team a great team of workers.</p><p>http://www.friv8.in </p>
<p>This instructable is from 2006. No wonder the links are dead. This one should be canned...</p>
<p>Just tried the links and videos at the bottom of the 'structable, no go. The sites have both gone dark and are now place holders and the videos are messed up, VLC wouldn't even show the videos - so be wary. The build however looks impressive.</p>
I am trying (somehow) to put this together with a waveboard to make it hover at least a foot. can anyone help?
f=ma my friend. it is the most important thing you will ever learn.
I'm assuming that f = either force or fuel. m = mass. what is a?
force = mass * acceleration. Newton's second law of motion.
<p>Gravity should be included in the calculation. Newton wasn't in touch with gravity in space or black holes, etc.</p>
i thought it was the third law of motion?
Nope, it's the second law:<br> <br> From http://en.wikipedia.org/wiki/Newton's_laws_of_motion<br> <br> Second law: A body of mass m subject to a force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., <strong>F = ma</strong>. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body<br>
<p>you are right, but never, never ever ever quote Wikipedia</p>
<p>That quote is a verbatim quote from my college physics textbook which predates Wikipedia by about 30 years.</p>
force = mass X acceleration
How is this project coming?
