What types of engines are present in aircraft?
All the aircraft engines work on the Principle of Newton’s third law of motion. Aircraft engines require a system that can provide thrust so that the aircraft is propelled forward. In most aircraft engines the basic mechanism is to accelerate a working fluid that pushes the aeroplane forward, while the gas moves backwards with high force.
Gas Turbine Engines
Most of the modern aircraft engines are powered by the gas turbine engines which are also called as the Jet engines. They are called Jet engines because the take in a lot of air, compress it and pushes it behind through a nozzle at high pressure, which gives the aircraft the necessary thrust to move forward.

Jet engines are further classified Turbofans, TurboShaft and TurboProp Engines. All these engines use the same principle of Jet engines but they are put to different uses. The Turboprop engine uses energy from the engine to run fans mounted on the outside of the plane. TurboShaft engines are similar to Turboprop engines except that the shaft is used to power a variety of additional gadgets. The Turbofan engine has additional fans located on the front of the aircraft that draws additional air into the engine
Piston Engines
Piston engine are internal combustion engines that burn a mixture of fuel and air inside a combustion chamber. The chamber is provided with a piston that moves within the compression chamber. The energy for the movement of the piston is provided by the air-fuel mixture. Piston engines operate similar to the car and other automobile engines. In its basic operation, a valve in the engine permits air into the chamber (called the cylinder) which is compressed by the moving piston. When an appropriate compression is reached, fuel is allowed into the compressed air through another inlet as a fine spray. Finally, the compressed fuel-air mixture is ignited with a spark provided by a spark plug, which causes the mixture to explode violently. The explosive power is used to move the piston back, and remove the exhaust gases from the compression chamber. The return movement of the piston is conveyed to the wheel and fans of the aircraft which causes it to rotate at high speed. In a propeller powered aircraft, much of the thrust is created by the propellers, which creates the upward lift for the aircraft.
Rocket Engines
Rocket engines produce the most power in the class of aircraft engines. They need so much of power in order to push the aircraft outside the gravitational pull of the earth. Rocket engines use a mixture of oxygen and a very combustible material to produce the thrust. The uniqueness of the rocket engine is that it carries its own oxygen to ignite its fuel. This is very different from the working of the jet engine, which takes air from the surroundings to ignite the fuel. Hence, a rocket engine can go into space where there is no air.
