Rotor

 

For design missions where the aircraft needs to spend a large amount of time in hover, the rotor is the most efficient lifting device. However, it is very difficult for the rotor to propel the aircraft forward and provide lift at a high velocity. In order to increase maximum velocity, a variety of methods have been used to add propellers and wings to rotor aircraft, forming compound helicopters.

Aircraft in this sub-category include:

Kamov Ka-22

Piasecki 16H-1

Lockheed AH-56
