How plane engine works?

Answer 1

In its simplest form, * A plane (jet) engine is affixed with a fan at the front of the engine with a shaft that runs right through to the turbine. This enables the fan to abstract cold air and propel it into the next stage of the engine. (cold air accommodates more oxygen making it efficient in the combustion process.)

* As the cold air is drawn into the engine, it is directed into the compressor where the air pressure will radically increase for the combustion process.

* This compressed air is then infiltrated with jet fuel via the wing fuel supply.

* The air fuel mixture is then ignited to commence the combustion process causing the air to dramatically expand in the chamber and in turn creating exhaust gas.

* This increment of energy escapes through the narrow end of the engine (turbine) at high a velocity to create the forward propelling motion.

* The combination of the tilt of the wing (airfoil) and the high speeds of the aircraft induce the lift off the ground. Copyright © 2009 Answers Corporation

* This increment of energy escapes through the narrow end of the engine (turbine) at great force to create the propelling motion.

Answer 3

Modern 747's are powered by turbofan engines.

A turbofan works by the main fan, at the front of the engine, drawing in air. This air then travels one of two ways; it either bypasses the core (mentioned further on) or it travels through the core. The air that bypasses the core has been sped up by the front fan and exits the engine at the rear of the engine which pushes the aircraft forwards. Air that passes through the core, first of all, is compressed by a series of compressor fans which increases the airs pressure and increases the temperature of the air. This air then enters the combustor which mixes the air with fuel and this mixture is then ignited. Next, the hot gas expands and spins the turbine which powers the compressor and the front fan. Finally, the gas passes through a convergent nozzle into the atmosphere, creating a high velocity jet which pushes the aircraft.
