The idea of contra-rotating propellers entails the set up of two propellers on a single piston or turboprop engine, one positioned instantly behind the opposite, rotating in reverse instructions on the identical axis. This creates an interesting synchronized movement, the place one propeller spins clockwise whereas the opposite spins counterclockwise. At low speeds throughout flight, the spinning blades of a propeller generate vital rotational airflow. In a single-rotor design, this airflow is commonly wasted, and may result in stability points, inflicting the plane to show left or proper relying on the propeller’s rotation route – referred to as torque impact. Thereby, the presence of contra-rotating propellers maximizes the utilization of this airflow, providing excessive efficiency and minimal vitality loss whereas countering the torque impact.
