could you tell me what the material of the nozzle??  I hope your answer!!!!!!!!!

[AN3jets]

@Narutz09 Hi, the nozzle is made fron high grade stainless steel. 1mm wall thickness 90mm diameter.

Hi there.

What motor are you using to start the engine?

Thanks

[AN3jets]

@biggiginthesky Hi. It is a 140w old kitchen blender that I modified.

[carlos611122]

are you using an axial flow turbine? if not, how did you addapted the anular combustor to work with a centrifugal turbine?

[AN3jets]

Hi carlos, thanks, no I am using a centrifugal turbine that came off the turbo. First you swirl the hot air in the same direction as the shaft's rotation and then bend it towards the shaft and the second set of nozel guide vanes are set at the same angle that was used in the turbo are swirling the air towards the turbine. In some instances with a verry compact engine this can be done simultanuesly. The JPX and Sophia modelRC engine had the same setup.

I really like he way you fabbed this one up.

very sleek and compact, I applauded when I saw it.

Great work!

how do u expect to run it with out oil without tearing it up?

[m13m44]

Plz can u explain how u made it and the material u use it and a schematic for it

[luiz8232]

Very nice. Congratulations.

How did you get the spark plug to spark constantly ??

[toothfairy898]

Neat turn out! I have a turbo @ batgoldfly

re doing some combustion components and will do a run up on you tube later this year.

looks like you took the pains to use turbo charger parts in your own design rather than just adding on a burner section to a junk yard auto turbo as others do.

@carlosr428 Foil bearing.

I was very impressed with this video. Indeed very interesting and successful project. Indeed cought my interest 110% how to build one of these. I wanted to ask - what kind of fuel does he needs? How exactly you calculated thrust-to-weight ratio, so you could build platform for it with enough wieght so your engine would stay in place instead of firing like a rocket? Where did you get info about MAX temps (i.e. exhaust)? How to calculate them? And last - how much your project cost to you?

[Norredam]

Where did you get the inspiration to build this?

I want to build a jet engine myself, but whats your suggestion on where to start?

Do you know if theres anywhere to get blueprints for this? :)

great vid!!

[ungas2890]

what kind of combustor did u use?....multican?...or anular?...and di u replaced the metal used for the turbine/...or u just used the original?

[dango85]

Very nice! Big stuff!! what about installing a after burner??

[bbhbhhnjny1]

hey were did u get the blueprints for this???
