WebThe reason for using C C to describe aileron-control braking effectiveness is that only the chordwise force produces torque (assuming a wind turbine blade with no pitch or twist). Because of this direct relationship between chordwise force and rotor torque, C C serves as a convenient parameter for evaluating an aileron's braking effectiveness.
