The invention belongs to the technical field of aircraft braking systems, and particularly relates to a control system and method for keeping the course of an aircraft in the braking process based on braking force. A set of hydraulic source is adopted for supplying pressure, the hydraulic source enters six brake control valves respectively, each brake control valve is connected with two brake main machine wheels, eight machine wheels of a front axle and eight machine wheels of a rear axle are connected with a main undercarriage structure through brake pull rods, and brake force sensors are arranged on the eight brake pull rods. Signals of the brake instruction sensor and the brake force sensor enter the brake controller, and after the sensor signals are resolved, the brake controller outputs a control instruction to the brake control valve. According to the application, the aircraft can be prevented from yawing due to inconsistent braking forces generated by the left and right main wheels in the braking process when the aircraft skates on the ground, so that the safety of the aircraft is effectively improved, and the air service control burden is relieved.
本申请属于飞机刹车系统技术领域,特别涉及一种基于刹车力的刹车过程中保持飞机航向的控制系统及方法。本申请采用一套液压源进行供压,液压源分别进入6个刹车控制阀,每个刹车控制阀接2个刹车主机轮,前轴和后轴的8个机轮通过刹车拉杆与主起落架结构相连,在8个刹车拉杆上均设置有刹车力传感器。刹车指令传感器和刹车力传感器信号进入刹车控制器,对传感器信号进行解算后,刹车控制器向刹车控制阀输出控制指令。本申请能够防止飞机在地面滑跑时,由于刹车过程中左右主机轮产生的刹车力不一致而导致飞机偏航,有效提高飞机的安全性,减轻空勤操纵负担。
