Hi can you make a tutorial for making this thx!

Will it blend? :]
if it can sustain a flame... not a jet, a flame, all you have managed to do is waste some time and break up a perfectly fine lighter

You dont even understand how mad i got when i saw this,
so mad i took the time to make a account on this website
just to tell you that the little piece of metal you made there has no way of working, ever.... making a turbine of this size is almost impossible
because of sustaining combustion at this scale is lust not possible. also you have no lubrication systems, no bearings, no combustors, no stators.
You have nothing here to support that this could ever work.
Your metals i am sure are just some carbon steel so this thing would melt itself before it began to self sutain, not to mention its idle rpm would be around
100 000rpm because of its size.

so please dont come here with your lies
thank you
Amen!

Eloquently put.....
for more thrust use diffrent types of fule
Great start, even if it starts and melts, I would be interested in video,Interested pulse jet fan!

Hello can you post instructions on how to build this I don't understand the pics
The SuperNatural (author)  galoo1232 years ago
i will post one of the instructions it will be up soon
are you trying to build one?
i am but don't understand the steps, a step-by-step or a video would be cool

Sorry
There are too many inconsistencies with your replies, and the physics in some of your replies just don't add up, for this planet at least for example you mentioned "3 blades power it and it is better to have one opposite direction for more thrust" HUH?, on one of your replies that used "super glue and lead" to attatch the turbine blades to the shaft and that the tip only got hot not the fan section later completely changing the story, it runs with combustion within it for 15-20 minutes and it's held together with superglue and lead (low melting). That's just to mention a couple
Im done on this subject, being HONEST, and based on your instructable, which is doing nothing thaT name implies, you keep referencing pictures or angles you don't show.....
I think it's a little insulting to the people who put effort into listing an honest, complete instructable it's insulting that you post such a FALSE piece, and edit your replies after the fact, THERE IS NO WAY THIS WOULD OPPERATE AS A JET ENGINE, BASED ON YOUR INSTRUCTABLE AND YOUR SHIFTING EXPLANATIONS AND "PARTS YOU CAN'T SEE...MAYBE AN ELECTRIC FAN POWERED TORCH .... BUT NOT A JET... POST A VIDEO..... DONE
THANKS supernatural?

oh my god you are driving me crazy but its ok i have told you that i have lost a piece or two while being shipped here ok???
and i used superglue and lead as i mentioned to hold the blades but i never said i used it at the hottest part!!! it is near the end blades and the motor and also when i tested the blades backwards it gave me more thrust. ok???? maybe i could have curved the blade weird or something
so stop making bad comments..
i am not joking it does work
and i want to post a #$^$^%@$^%$^#^#@%@ video!!!!
i really want to okay???
2 months and no video yet.....
Still waiting on that video, fraudsteez.

I have to see video of it running before I vote, I have worked on jet cat turbines, the tolerances and components required for a turbine to function not to mention temperatures and materials are complex and expensive..a few problems I see...Your intake is non existent, there is no ignition source, no chamber separation , I guess it all boils down to how you define what a functional jet engine is.... Not trying to be mean, just, need more proof. My friend B Wilcox managed to build a 2.5" kerosene turbine and the support equipment to run it alone took up 4 times the space the turbine in its test stand.
Again not trying to be mean just want to see it working, that's all...
The SuperNatural (author)  hellboy2 years ago
yes well bellboy I see that you know a lot about jet turbines yes and i also do as you mentioned there are no intake? well there is if you can see the picture closer there are square bits which is rotatable to change the airflow and also removable and the ignition source is taken apart i used a electric lighter igniter which is used for lighters and also some of the parts are missing because i shipped it and it got damaged on the way. and yes we need a combustion chamber and few more turbine blades. and also i used very little space as you mentioned that yours took up 4times more space. but i found all the small parts i needed actually which i handmade my self. and they are very cheap it can withstand the temperature and the force.
P.S i would like to see your friends jet too thanks

Hello
Still with all the tabs open your intake orifice to exhaust is off, the exhaust end uses the Venturi principal to concentrate the output of the jet making the hole smaller than the intake, small jet engines use ceramic bearings due to the high temperatures, how hot and how long can you run it? Please post more pictures and definitely a video of it running...
Thanks
The SuperNatural (author)  hellboy2 years ago
yes, again hellboy you are telling that my exhaust hole is too wide? you cannot see the whole thing form picture there is a big groove that centers all the thrust made by the jet and i also lost a part while moving to a different house. it is a little cap with four thin wire strips that can be placed on the exhaust hole to make the exhaust smaller which makes it give more thrust. I can run his mini jet for about 30 min non stop after that only the blades and the exhaust is hot because of the gas that ignited inside. well hope that helped you.
P.S I want to see yours
-The SuperNatural-
Sorry made no sense, just post a video of it running to shut me up....and just to clarify your combustion is taking place within the jet and running for 1/2 an hour means its super efficient, must see video..... where does your igniter go?
And what temperatures are you talking about?
There are two that I worked with and they belong, as I said my friend Bob Wilcox, look him up, he's a jet guru and a good teacher.
Thanks

The SuperNatural (author)  hellboy2 years ago
Well if you have seen the picture closely there is a moter that creates more thrust and speed and also I told you I ignite it with a electric lighter igniter. And sorry I told you the maximum time the maximum time is 30min and normal time it can run is about 15- 20 min yes it is quite efficient. And you also need to wait a bit because in the picture some parts are not shown which means it is damaged while being shipped or lost and now I live in a apartment so I might have some hard time making it back
I will finish it and upload the video in few weeks if I could
If you vote for me I promise you I will finish the jet and private message you and everyone else the jet operating
And remember the fuel used in this jet is not oil or anything else it is gas
And the temperature is very hot after running it for 30min i can't measure the temperature but it sure is hot
P.S private message me if you have any questions
sorry Hellboy wrote your name wrong

Hi : This is really cool,
I'm Just checking on the correct angles of the compressor and intake turbines ??
Are they fixed (welded ) to the shaft,and if yes it looks like they will not produce any pressure since they are on the opposite direction.

please specify
Thanks
The SuperNatural (author)  mbourhan2 years ago
as you can see the whole thing is very tiny so you don't need that much energy to run it and you asked that the angles are different? yes but they do create thrust because the whole thing makes pressure in the combustion chamber which i did not show but when its lit the combustion chamber and the other 3 blades power it and it is better to have one opposite direction for more thrust thanks and vote for me in the contest.

This is cool. you need to add a video to this post
The SuperNatural (author)  tstupple2 years ago
thanks i think i am good enough for a 15 years old
and yes i will post a video soon
Please, PM me when done.

and pics or vid of it working?
The SuperNatural (author)  Bongmaster2 years ago
i want to show you but i have to find a ball baring to support it i will show it soon thank you Bongmaster
plez vote on the pocket sized contest thank you again
