Author Topic: exotic engine list (Read 1444 times)

I am writing a paper which involves powerplants a little more exotic then the regular piston and turbofan. What I have so far are:

ram jets
scram jets
solar
pulse jets
nuclear (both the NB-36H testbed and Pluto Project)
rocket

Seems like there should be more to the list so feel free to mention anything.

steam
coal (germans thought about making a coal powered a/c at end of wwii)
wind driven (like the top 'wing' of an auto gyro)
Human pedal power

erm........ thats about all i can think of right now

hydrogen?

I like the sound of that coal powered one. That's when you know you're down and out in a war.

Hitech, I would use Ion drives but I won't be leaving the atmosphere for this paper.

Yes, hydrogen has been used as a fuel for high altitude ram jet tests.

I know Germany tested and used hydrogen peroxide for one of their submarines. I believe the hull for that test model was used in the type XXI by the end of the war.

Actually most late war LW aircraft were coal powered, indirectly at least, as the synthetic German aviation fuels were derived from coal.

Don't forget wankel rotary engines.

Turbo-compound recip engines are pretty complex: multiple exhaust-driven turbines, with one turbine geared to help spin the crankshaft, and one turbine spinning an intake charge compressor...

Burrito power. Methane.

a matter/ anit-matter injection type matrix
Using a crystal type structure to regulate the 2 streams therfore producing energy..

Actually its no joke. When Rodenberry was first developing star trek he had several scientists that worked together to give him a hypothetical futuristic way to power a starship. So it is possible.linkage from smart people

Vacuum Energy.

A long time ago I read about a guy who was proposing that if vacuum energy could be harnessed, it could be used to propel almost anything since the energy output was enormous and inexhaustible...in space by using the energy to create high energy particles to shoot rearward of the craft (same principle as ion engine..only on steroids), in the atmosphere using that energy to superheat the air and expel it as propulsion (kinda like a jet engine without having to mix fuel to ignite it)

Isotta Fraschini L. 121/R.C. 40 used in the CC-2 Caproni. Reciprocating engine to drive the compressors for a jet.

Also the English, Bristol I believe, designed a stupendously complicated hybrid recip/turbine. I'm not aware that it actually flew on anything.

Just wondering... did anything ever fly with a steam engine as power source?

Alot of BS in that area it's funny if you look around...... but the genral Idea exisits ....yes .... noones really built anything that works yet.

But some of the thoeries state that inertia is an effect caused by 'resistance' in the zero-point "vacuum"

It's an odd idea ... experiments ahve more or less proved it's exsistance .... it's exsistance however does not prove it can be harnessed as a power source .... this might however change if we can work our brains around it ....

read this book once .. intresting read .. some off the wall stuff .... but written by a Janes man.....

and check out the such questions as the Aurora, some think the technology exisists .. it's just being kept black...

::shrugs:: I just find it intresting that Boeing is spending money on anti-gravity research which is based around all this stuff......
