the jet propulsion with closed combustion type

[DFINITLYDISTRUBD]

aaahh! another doodeler!!!! I've got notebooks upon notebooks of drawings like that starting from when I was 11 to the present date. I'm still filling them!! with engines,electric motors, electronic circuits, wing designs, hull designs, sail designs, propellor designs, aerodynamic studies in design, etc. !!!!!!!!!

I repeat:
"cloesed combustion has more efficiency though it mat be hard to control"

If you only seal one end and open another end( or close to open), the effect will be influenced seriously. You should think a method.

If is because the turbine absorbs less energy than current engine.

The new engine Ive mentioned above will have reeds for intake and exhaust!!
I've recently acquired six very heavy duty looking reed valves that should be able to take the abuse at the exhuast end. (finally)

If they can't I'm looking into replacing the reed portion of the valves which are steel with either titanium ,tungsten or berillium reeds which I will likely have to have custom made.

Ok, thank you.

we can allow the combustion nearly to closed, not allow it nearlly to open.

If you really want to order an expensive reed valve, I suggest you would rather start from a new design of valve: ( New structure than common) . You can compare which has better function as well as compare their prices.
Pls consider

Attachment 477(Hope this works!)

HOT DAMN IT DID!!!!!!

Computers sure can be complicated at times!!!!!!!!!

I really don't want too (money is expensive) but it's either that or order a just as expensive other type of system. I like using reed valves because they are simple and have very few moving parts.(depending on type they typically only have between 1 and 4 gates which are simply flaps of metal that are opened by flow of air or fluid through them in 1 direction then closed by flow in the opposite direction. Doesn't get any simpler or cheaper to make than that!
