changes, a fact which killed many experienced pilots when they attempted the transition to jets. These drawbacks eventually led to the downfall of the pure turbojet, and only a handful of types are still in production. The last airliner that used turbojets was the Concorde, whose Mach 2 airs...
Airbreathing jet engines of the ram-powered variety, such as the ramjet, are typically considered more straightforward and more reliable than conventional ones since they contain fewer moving parts. The turbojet uses turbines to pull in and compress air before feeding it into the combustion ...

MODERN turbojet engines have a shaft speed range of approximately 2 to 1 (from ground idle to take-off) and it is necessary, therefore, to have some form of infinitely-variable-ratio gearbox to obtain a constant speed for accessories such as a.c. generators. Various means of doing this ...
A jet engine is any of a class of internal-combustion engines that propel aircraft by means of the rearward discharge of a jet of fluid, usually hot exhaust gases generated by burning fuel with air drawn in from the atmosphere.
Rocket and missile system, any of a variety of weapons systems that deliver explosive warheads to their targets by means of rocket propulsion. Rocket is a general term used broadly to describe a variety of jet-propelled missiles in which forward motion r
