None in production.
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.
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.
Basically, the engine of the airplane provides thrust, which help it go forward. There are many types of engines that can do the job.
It depends on the size of the aircraft. A smaller airplane like Cessna has only one engine. The biggest cargo plane like Antonov has six engines.
Depends on the airplane size and engines used.
The thrust is an airplane is provided by the engines.
