Airplane heavy landing indicating device

The invention provides an aircraft heavy landing indicating device, which mainly comprises a turntable (3), a pointer (4) and a conversion device, and is used for measuring and displaying the magnitude of ground impact force on an aircraft during landing by converting the movement distance of a piston rod (8) of an aircraft landing gear into the rotation angle range of the pointer (4) on the turntable (3). The device is simple in structure, low in manufacturing cost and convenient to install, operate and use due to the fact that the device is installed on the aircraft landing gear, field staffcan rapidly read the indication condition of the device after the aircraft lands, and therefore maintenance or repair operation is conducted, and the attendance rate of the aircraft is guaranteed. 本发明提供一种飞机重着陆指示装置，主要包括转盘（3）、指针（4）和转换装置组成，通过将飞机起落架的活塞杆（8）的运动距离转换为转盘（3）上指针（4）转动角度范围，来测量和显示飞机降落时受地面冲击力大小情况。该装置结构简单，制造成本低，因安装在飞机起落架上，安装和操作使用方便，外场地勤人员在飞机降落后迅速读取装置的指示情况，从而进行维护或维修操作，保证了飞机的出勤率。
