The invention belongs to the technical field of airplane wheel brake systems, discloses a multi-wheel frame main landing gear airplane fly-by-wire brake control system and method, and provides an airplane multi-wheel fly-by-wire brake control method and system. According to the technical scheme, in a high-speed section, rear-row wheel brakes are weakened, front-row wheel brakes are strengthened toadapt to brake head lowering torque, so that ground normal force distribution of front-row wheels and rear-row wheels is achieved, that is, the normal force of the front-row wheels is larger than that of the rear-row wheels, excessive slipping of the rear-row wheels is reduced, and the purposes of improving airplane braking efficiency, shortening the sliding distance, and reducing the tire abrasion of the rear row wheel are achieved.
本发明属于飞机机轮刹车系统技术领域,公开了一种多轮车架主起落架飞机电传刹车控制系统及方法,提出了一种飞机多轮电传刹车控制方法及系统。本发明解决技术途径是:在高速段,弱化后排轮刹车,强化前排轮刹车,以适应刹车低头力矩使前后排轮的地面法向力分配,即前排轮的法向力比后排轮的增大,从而减少后排轮的过渡打滑,达到提高飞机刹车效率低,缩短滑跑距离和减少后排轮的轮胎磨损的目的。
