A brief analysis of the working principle of Rotorcraft shell flight!

In flight, the most obvious difference between the rotorcraft and the helicopter is that the rotor of the helicopter is tilted forward, while the rotor of the rotorcraft is tilted backward.

It should be noted that when some rotorcraft take off, the rotor can also be connected to the engine through a "clutch", and the engine drives the rotation to generate lifting force. This can shorten the take-off and run distance, and climb almost steeply, but it can't ascend vertically, nor can it stay still in the air (ie, "hover"). After lift-off, release the clutch and follow the rotor to spin freely in the air. Rotorcraft shell

When a rotorcraft is flying, the lift is mainly generated by the rotor, and the fixed wing only provides part of the lift. Some rotorcraft do not even have a fixed wing, and all the lift is generated by the rotor. Rotorcraft shell
