Engine is the main component of the any body that is vehicle.with out engine body cant move forward.According to the newtons first law of motion the body will not move unless the force will act on that body.All these principles make the design of a vehicle that uses to travel from one place to another place.Same type of situation will respond in case of the aircraft's also.In aircraft engine is the main one which drives the whole body in to the motion from the static point to air borne.Air craft engines will be classified below.
1.Piston Engine
2.Turbo Fan or Prop Engine
3.Turbo Jet
4.Ram Jet.
1.Piston Engine :This type of engine is uses in the small aircraft that is two sitter aircraft.Actually we are using the four stroke piston engine in the aircraft means it has the four different type of strokes works individually to drive the engine.It has the all parameters that explains the standards of the engine and its performance.Same as the auto vehicles its also having the staring procedure it comes under the flying procedure.This type of engines will be imported from the U.S.A.It has the speed limitations that works only in the limit of altitude that the oxygen supply will be available for the engine.
2.Turbo Prop Engine :This engines is uses the average vehicles that is the altitude and the crew of the aircraft will be limited for this engine.It has the compressor in front of the engine which sucks the air from the atmosphere and increase the pressure of that air slightly. And in the combustion chamber air and the fuel will be mixed and the ignition will be take place then the air and fuel mixture will burn out with the release of hot flame and gasses from the turbine section this turbine section will be increase the speed of the gasses passing out from the engine exit.In front of the engine it has the propeller to sucks the air and transfer the air from the atmosphere to engine compressor chamber.
3.Turbo Jet :Its also same as the turbo prop engine but it does not contain the propeller in front of the engine.Remain the work will be same as the above one like.It has the compressor in front of the engine which sucks the air from
the atmosphere and increase the pressure of that air slightly. And in
the combustion chamber air and the fuel will be mixed and the ignition
will be take place then the air and fuel mixture will burn out with the
release of hot flame and gasses from the turbine section this turbine
section will be increase the speed of the gasses passing out from the
engine exit
4.Ram Jet Engine : It contains the ram pressure in front of the engine no moving component was appeared in this engine .Remain the working process will be same as the all engines working.
