Rigid helicopter rotor system
WebA Ukrainian Navy Kamov Ka-27. Coaxial rotors or coax rotors are a pair of helicopter rotors mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions ( contra-rotating ). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau . WebAt present, coaxial rigid rotor compound helicopters and tilt-rotor aircraft have been developed rapidly [3,4,5,6]. The compound helicopter with a rigid coaxial rotor is one of the main configurations in the development of high-speed helicopters, and as the most important feature of the helicopter, the Advanced Blade Concept (ABC) rotor is ...

The rotor system found on helicopters can consist of a single main rotor or dual rotors. With most dual rotors, the rotors turn in opposite directions so the torque from one rotor is opposed by the torque of the other. This cancels the turning tendencies.
