That is the rotor hub and blades
Well, if you're referring to how a helicopter flies, the rotors on a helicopter are slanted and shaped so that when the rotors spin air slips under the rotor and gets pushed down therefore creating lift.... You need to check your grammar.
In the plenum tube that goes from the air filter box to the intake manifold. It is the only thing plugged into the large rubber tube ontop of the engine.
The Marine corps. It is called Marine one like the airplane by the air force the president uses is called air force one.

An air ambulance helicopter is generally the same as an ordinary helicopter except for the fact that it is equipped to save lives just as a regular ambulance is equipped. Air ambulance helicopters must have the medical supplies necessary to save lives.
The helicopter blades push air down. By Newton's third law, the air pushes the helicopter upward.
When a helicopter flies close to a water surface, the air below the helicopter is disturbed by the movement of the rotor blades. This disturbance can affect the lift generated by the rotor blades, leading to a loss of altitude due to reduced lift. This phenomenon is known as "ground effect."
Join the army or air force as a helicopter pilot.

A helicopter requires air to generate lift from its rotors. Since the moon has no atmosphere, there is no air for the helicopter to push against and create lift. This makes it impossible for a traditional helicopter to work on the moon.
