Design method of interconnection struts between flaps of large transport aircraft

In the design of modern large transport aircraft, flap system has become a standard configuration, which can increase maximum wing lift and climb rate aircraft. Meanwhile, reliability always been focus point aviation industry. The interconnection strut between flaps is kind redundancy design, mitigates failure enhancing reliability. Since 1980s, aircraft manufacturers such as Airbus Boeing have designed many kinds ICS for like A320, B737. there some study on in China, still its infancy. this paper, method studied, important parameters are proposed. A new designed, validity rationality verified. Firstly, multi-body dynamic model established working principle studied; then energy absorbing characteristics elements finally, mechanical properties mitigation effect simulated to verify effectiveness design.
