Why does chinook have two rotors?
The two rotors are linked by a transmission that ensures the rotors are synchronized and do not hit each other, even during an engine failure. Tandem rotor designs achieve yaw by applying opposite left and right cyclic to each rotor, effectively pulling both ends of the helicopter in opposite directions.
Do Chinook blades counter rotate?
Tandem-rotor helicopters such as the CH-47 Chinook also use a counter-rotating arrangement. The efficiency of a contra-rotating propeller is somewhat offset by its mechanical complexity.
How do Chinook rotors work?
Lift, in a Chinook helicopter, is produced by a rotor system consisting of two fully articulated counter-rotating rotors. The forward rotor is driven by the forward transmission through the rotor drive train. The aft rotor is driven by the aft transmission through a vertical drive shaft.
Does a Chinook have a tail rotor?
Tandem rotor helicopters like the CH47 have two lifting rotor discs and no tail rotor as the counter-rotating discs cancel out the twist of the rotor discs.
Can a helicopter fly without a tail rotor?
One significant advancement in the last decade has been the no-tail rotor, or NOTAR, helicopter. As you now know, vertical-lift flight is impossible without a tail rotor to counteract the torque produced by the main rotor.
