Any good Russian books?
The coaxial uses differential collective for yaw control. What are the aerodynamics at the rotors that caused Kamov to incorporate automatic pedal reversal for autorotations?
Just before the autorotating coaxial touches down, the pilot raises the collective to consume some of the rotational energy in the rotors. Does the helicopter get schizophrenia as its pedals try to decide which direction of rotation they are responsible for?
