Trailing-edge flaps Calculator

Trailing-edge flaps are aerodynamic control surfaces mounted on the trailing edge of an aircraft’s wings. They are hinged at the back edge of the wing and can be extended or retracted during flight. Trailing-edge flaps serve multiple purposes, primarily to increase the lift and/or alter the camber of the wing, allowing the aircraft to operate at lower speeds during takeoff and landing while maintaining controllability.

Where:

  • is the change in lift coefficient
  • is a constant related to the specific flap design and aircraft configuration
  • is the deflection angle of the trailing-edge flap in radians
