The invention provides an airplane instantaneous sinking speed measuring device and a measuring method thereof. The device comprises a square box, a square cylinder, a balancing weight, a left friction brake block and a right friction brake block. The square box is mounted on a main undercarriage of the aircraft; a square hole is formed in the square box; scale marks are transversely arranged on the front side surface of the square box; the square column body is vertically sleeved in the square hole; scale marks are arranged on the front side surface of the square column body; a window is arranged on the square box; the balancing weight is mounted at the lower end of the square cylinder; the left friction brake block and the right friction brake block are attached to the left side face andthe right side face of the square cylinder correspondingly. When the aircraft lands or lands, the whole body formed by the square column body and the balancing weight can move downwards in one direction along the square box until the aircraft is static relative to the square box. The device can directly measure the sinking speed of the airplane at the moment of landing, is more direct, simpler and clearer compared with a flight parameter recording system used at present, and can also be widely applied to speed data acquisition of occasions such as automobile collision tests and civil equipment drop tests.

    本发明提供一种飞机瞬时下沉速度测量装置及其测量方法,该装置包括方形盒、方形柱体、配重块、左摩擦制动块、右摩擦制动块;方形盒安装在飞机主起落架上;在方形盒内设有方形孔;在方形盒前侧面横向设有刻度标线;方形柱体竖向套设在方形孔内;在方形柱体前侧面设有刻度线;在方形盒上设有视窗;配重块安装在方形柱体下端;左摩擦制动块与右摩擦制动块分别贴合在方形柱体左右两侧面上;飞机着舰或着陆时,方形柱体和配重块构成的整体能沿方形盒向下单向运动直至相对方形盒静止。本发明可以直接测量飞机着陆瞬时的下沉速度,与目前使用的飞参记录系统相比,更直接、简单明了,也可广泛应用于汽车碰撞测试、民用设备跌落试验等场合的速度数据采集。
