7,000 mph with No Moving Parts

NASA's X-43A is the ultimate in keep it simple thinking. The engine, know as a scramjet, actually has no moving parts.

Scramjet burns fuel in a stream of supersonic air compressed by the forward speed of the aircraft. Conventional jet engines draw in air and burn it with fuel so it expands in a combustion chamber. The hot air is then forced out the exhaust nozzle to produce thrust.
