fd3/64 gas turbine jet engine

[pizzagorgonzola]

it amazes me how similar it sounds to much bigger engines.

[spacemonkeys0681]

how much thrust

[rainerfilm]

Just imagine that the rope snaps and your engine becomes a rocket.

[reedy93]

@rainerfilm Two 6mm cap heads in slots only allow it to move 40mm .the rope is steel wire so it,s not going any where

[flyingpigstuff]

Every farmer should have one of these connected to a poop digester.

You Talk To Much Just Reeevit Up

[JDKMM7]

Where did you find the fan?

[reedy93]

made it same shape as wooden wheel but turned and milled out of ally with no cover and runs with 0.08mm. max clearance to nylon inlet. drawing in the gtba newsletter

[JDKMM7]

so you cast it yourself?

[reedy93]

the turbine wheel on this engine is as drawing, made out of 1/8 inch thick 310 stainless welded to a boss with the blades hacksawed out and hand ground to shape with the angle of the blades twisted on,the compressor wheel is milled out of an ally blank no casting on this engine.

[Fassja]

Whera i can buy this?

[haseeb8181]

please guide me in making such a engine

[TORCHforAMERICA]

how much did it cost

[reedy93]

hard one to answer as depends how much you do yourself and if you can find the material for free,cost me about £100 and a lot of spare time,if you what one to fly a jet its cheaper to do the overtime and buy one but not as satisfying

[HurtfulProductions]

Could you send some schematics of this engine my current one does not have enough power for what I am disigning

[reedy93]

it,e all in the book Gas Turbines for Model Aircraft by Kurt Schreckling ...just google it ,has all drawings ,math and building instructions.

[bignitro50]

Wow I can see the metal change colors at 1:40

[Blazinjayson]

carefull that thing miht fly thru that window there...

[JustWonderingHowToDo]

Excellent, really nice job.

I know that this type of turbine is an older type. How much trust does it have and how does thet compare to the newer turbines that are sold today. Where do they get there extra trust.

[rudeboyzero]

Modern turbines are much further developed, and use high tech materials, allowing them to run at much higher speeds => more thrust.

Also, better diffusers, combustors, compressors, turbines and NGV's these days mean turbines are much more effecient.

Bearing design also plays a vital role. In the old days, these things were running on ordinary caged steel 1$ bearings...while todays turbines run on cageless ceramic bearings.

[reedy93]

agree with everthing you say but you can make all the bits yourself with this design ,like you say power is only 5 lb if you really push it with a ally wheel and m/c turbine wheel 7lb but i think if you need more power build kj66 or buy one of the new design for 22lb plus in the same size case

[XeadXhot]

Do you have a design?

I'd use 2 of them to generate electricity and power a gocart.

[gschjetne]

A single turbine with a mechanical reduction gear would probably be much lighter and much more efficient. But at that scale a mass-produced IC engine is much cheaper, easier to use and less complex.

[reedy93]

can,t argue with that statement

[01driver]

I just love jet turbines! That is sweet!

[turbofanman1]

hahhahahahahahahaha

[scolen3]

what did it cost you to make one over buying an already made jet?

[jman1gall1]

dude plz tell me how much and how to make one i wanna put 4 -6 of those bad boys on a set of wings like that jet man SERIOULY

[turbofanman1]

HAHHAHAHAHAHHAHHAHHAHAH

[slartibartfast69]

brilliant to see an FD3 working.

checkout my vids, i've made some videos of my jet engines you might find interesting

[maxou5757]

Nice but Ge90-115's are better

[bradleydenniswarren]

hi, im a student and i was very fascinated by your jet engine. i am interested in mechanics and technology and i thought this would be an excellent project for me and a few of friends and some teachers to work on. so if you could possibly send me some parts or even theblueprints used in your engine that would be much appreciated

[kimmer6]

Go to work for General Electric in Schenectady, NY. They make some of the best industrial gas turbines in the world. See the world on their expenses. Get a good reputation and some other ex-GE employees will pay you $30K a month if you're good at it.

[kimmer6]

Bradley, don't pay attention to the ass scab who said nerd. I filled a 32 page passport in 18 months, bought a Ferrari 308 when I was 29 and did some stuff you only see in an action movie. Life is easy now. I retired before 50.

[reedy93]

the book GAS TURBINES FOR MODEL AIRCRAFT by Kurt Schreckling has the drawings that the engine is based on.( fd3/64) but with mods to improve -ally comp wheel-combuster with walking stick vapouriser designed by mark drake-stainless body etc.

[stickman101cv]

hi there i have a fd3/64 but with out a exhaust nozzle any ideas where to get one

[simonwass]

make one, the fd3 was a home build engine with no parts. there was a commercial engine the fd3/67 but its parts would not fit the fd3/64

[9P38lightning]

Looks good dude! Who did your Fabrication work? I have Started one just like it all drawn on cad, alu open fronted compresser wheel. And the jig fixture is made for the turbine. Turbines are made from various st/st. And I have done all my own programming for all machined parts. The front diffuser is one piece out of titanium But I am clueless on the fab work.

Can you help.

[marck757]

Very dangerous the way you did that.

[ben45smith]

Thats louder than a real damn jet engine... christ man did you put a megaphone on the end of that or something..?? anyways that is bloody cool.. im just about to start on a little turbo fan myself... only its gonna be electric for now... ill build a different one at a later date

[reedy93]

it is a real damn jet engine...just smaller,camera mic,s get swamped with jet noise.i,m just finishing electric ducted fan sea harrier.i will try to put my kj66 on if it stops raining.

[JETS4]

your turbine is great! its the first model turbine home made

[reedy93]

did it sunday..the gas had got hot in the sun fully manual start..it was only the gas that flamed..i had safty glass's..ear defenders and fire extinguisher and fan start to blow gas away

[superskullmaster]

dude get a proper starting system, thats impractical and semi dangerous the way you did that.

[simonwass]

nothing wrong doing it manually, we all did before the fancy ecu's. all an ecu does is check what an experienced man can do, i start my fd3 manually, never have a problem. if i can build it (including the turbine and compressor wheels) then i'm capable of starting it! video shows a very good start with no flames out the back, and only a blueing of the casing, mine has a hot spot which cools once sustaining.
