There is no such large airplane so far and such large ones will be necessary and impossible
The noise of the airplane comes from the engines.
Basically, the engine of the airplane provides thrust, which help it go forward. There are many types of engines that can do the job.
Depends on the airplane size and engines used.
The thrust is an airplane is provided by the engines.
The engines, driving propellers or jets, make the airplane move.
An airplane accelerates due to the thrust generated by its engines. As the engines produce forward thrust, the aircraft gains speed. The thrust must overcome drag forces acting on the airplane to achieve acceleration.
An engine producing THRUST keeps an airplane moving forward. Types of engines used by airplanes include reciprocating engines, turbo prop engines, turbojet, and turbofan engines. Some manufacturers are developing electric engines and one bicycle racer powered a very lightweight airplane using pedal power connected to a propeller.
