A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines.
Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much … See more

Most people use the term 'jet aircraft' to denote gas turbine based airbreathing jet engines, but rockets and scramjets are both also propelled by jet propulsion.
Cruise missiles are … See more

Jet aircraft fly considerably differently than propeller aircraft.
One difference is that jet engines respond relatively slowly. This complicates takeoff and landing … See more

For a long range jet operating in the stratosphere, the speed of sound is constant, hence flying at fixed angle of attack and constant Mach number causes the aircraft to climb, without changing the value of the local speed of sound. In this case: See more

After the first instance of powered flight, a large number of jet engine designs were suggested. René Lorin, Morize, Harris proposed systems for creating a jet efflux.
After other jet … See more

Because of the way they work, the typical exhaust speed of jet engines is transonic or faster, therefore most jet aircraft need to fly at high speeds, … See more

There are several types of engine which operate by expelling hot gas:
• turbojet
• turbofan (which come in two main forms low bypass turbofan and high bypass turbofan)
• See more
