The invention provides an airplane sled device capable of achieving differential braking, and relates to the technical field of sled, the device comprises a main crow plate, and the top of the main crow plate is used for being connected with an undercarriage axle of an airplane. One end of the tail crow plate is rotationally connected to one end of the main crow plate, and a brake surface is arranged at the bottom of the tail crow plate; one end of the telescopic actuator is rotationally connected to the top of the tail crow plate, the other end of the telescopic actuator is used for being rotationally connected with an undercarriage supporting column of the aircraft, the telescopic actuator can drive the tail crow plate to rotate relative to the main crow plate, and when the aircraft lands, the telescopic actuator extends and puts down the tail crow plate, so that the brake surface is in contact with the snowfield or the ice surface, and the brake surface is in contact with the snowfield or the ice surface. The ground resistance in the landing skating process is increased, and the landing distance is shortened. The braking device is simple in structure, high in reliability, high in practicability and suitable for taking off and landing of the airplane on the snowfield or the ice surface.
本发明提供一种可差动刹车的飞机雪橇装置,涉及雪橇技术领域,该装置包括:主撬板,主撬板的顶部用于连接飞机的起落架轮轴。尾撬板,尾撬板的一端转动连接在主撬板的一端上,尾撬板的底部设有刹车面;伸缩作动器,伸缩作动器的一端转动连接在尾撬板顶部,伸缩作动器的另一端用于与飞机的起落架支柱转动连接,伸缩作动器能够带动尾撬板相对与主撬板转动,当飞机降落时,伸缩作动器伸长,放下尾撬板,使刹车面与雪地或冰面接触,增大着陆滑跑过程中地面阻力,有利于缩短着陆距离。该装置结构简单,可靠性高,是一种实用性较强的,适用于飞机雪地或者冰面起降的刹车装置。
