What is the function of a jet?

Answer 1

an Engine moves the airplane forward, with enough power it can fly straight up. generally it's the airplane wings that catch air and create/sustain lift. So basically all the engines do is move it forwarded.

Answer 2

A jet engine operates on the same principal as four-stroke piston engines in which it intakes air and mixes it with fuel, compresses the air-fuel mixture, ignites the mixture, and expels the exhaust gases. The difference is how the engines use that cycle of intake, compression, combustion, and exhaust and translate it into motion. Piston engines rotate a crankshaft, which also rotates series of gears and shafts that ultimately rotate the wheels of a car or propeller blade on a prop aircraft or boat. Jet engines create jet streams from the exhaust gas; that is, the force of the pressurized gas pushing through the air. Think of an inflated balloon with the untied end pinched and then suddenly let go: the balloon goes flying due to the pressure of the air escaping through the small opening. Design-wise they are also very different. Piston engines use at least one (usually more, and usually in an even number) to compress air. When ignited, the force of the combustion pushes the piston down and rotates the crankshaft. The continuous rotation of the crankshaft keeps the pistons moving up and the combustion keeps the pistons moving back down, sustained because when one piston (or set of pistons) is up, another is down. Modern jet engines use a fan or series of fans to compress the air, and then the escaping exhaust gas rotates a turbine. The turbine is connected to the compressor fans by a shaft, so when the turbines rotate, they also rotate the compressors, which continues to draw in more air. After the exhaust gases pass the turbines, they exit through the exhaust nozzle at high pressure.

Answer 3

A jet engine generates thrust by expelling hot gases at high speeds, propelling an aircraft forward. It allows the aircraft to fly at high speeds and altitudes efficiently.

Answer 4

To keep flying at the sky! LolJk ;)

Answer 5

they fart on airplanes
