Counter-rotating Propellers
Counter-rotating propellers refer to a pair of propellers that rotate in opposite directions on the same axis. These propellers are commonly used in aviation to increase the efficiency and performance of an aircraft. The counter-rotating propellers work by cancelling out the torque effect caused by a single propeller, which can cause the aircraft to roll in the opposite direction. This allows for better stability and control of the aircraft. Additionally, counter-rotating propellers can provide increased thrust and speed, as well as reduce noise and vibration. They are commonly used in military aircraft, helicopters, and some commercial aircraft.
