Everything You Need To Know About Ailerons

Pilot Institute

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. This shifts the ailerons Center of Gravity (C.G.) With enough mass added, the C.G.

The Role of Newton’s Third Law in Aviation

Pilot Institute

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.

Nothing Small About It

Another advantage of the counter-rotating props is the elimination of torque roll. This is the tendency to dig in the left tip float during takeoff while countering engine torque. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
