摘要

The spoiler of civil aircraft plays an important role in flight as one of the important control surfaces. Different from the high lift devices such as flap, slat and so on. the spoiler is used for reducing the speed or the altitude in flights, making roll maneuver with aileron, and breaking lift on the ground. Moreover, the deflection of spoiler is usually reached a large value, the aerodynamic load acting on the spoiler can be remarkable due to the large designed deflection angle. Thus, it is necessary to research the load acting on the spoiler in the design of civil aircraft load. This paper introduces the principle of the spoiler load of civil aircraft, and gives an engineering method for the spoiler load design of civil aircraft.
