The rotational force thats needed to move an object about an axis is called torque. The simplest formula for torque is: Torque = F x L L is the distance between the object and the axis of rotation, also called the moment arm. Adverse yaw is created due to the drag differential between the two sides of the aircraft.

These are called left turning tendencies and include P-factor, spiraling slipstream, torque, and gyroscopic precession. When an airplane starts a turn, there is more lift, and therefore, more drag created in the raised wing. When an airplane starts a turn, there is more lift, and therefore, more drag created in the raised wing.

The reaction in the form of increased thrust allows the aircraft to overcome drag and accelerate or climb. The complication with helicopters is that the main rotor is driven by an engine that applies a twisting force (torque) to spin it. Other Designs The tail rotor is not the only way to solve the torque reaction problem.

Combining the Gweduck’s advanced hull with its counter-rotating propellers means differential power allows crosswind water taxiing impossible in floatplanes along with higher hull-in-water taxiing speeds. “We Another advantage of the counter-rotating props is the elimination of torque roll. A not so obvious advantage is taxiing.
