The invention discloses a stable-descending vertical falling speed measuring device for an air-drop test, which comprises an air-drop platform, a shell, a static pressure sensor, an acceleration sensor, a pressure guide pipe, a static pressure pipe and a data storage unit, and is characterized in that the shell is arranged on the air-drop platform, the static pressure sensor and the acceleration sensor are both arranged in the shell, the static pressure pipe is arranged outside the shell, one end of the pressure guide pipe is connected with the static pressure sensor, the other end of the pressure guide pipe penetrates through the shell to be connected with the static pressure pipe, and the static pressure sensor and the acceleration sensor are connected with the data storage unit. According to the invention, a parachute stable descending vertical falling speed test before landing in the air-drop test is realized, the air-drop test cost is reduced, and the test reliability is improved.

本发明公开了一种空投试验用稳降垂直落速测量装置，包括空投货台、壳体、静压传感器、加速度传感器、引压导管、静压管和数据存储单元，壳体设置于空投货台上，静压传感器和加速度传感器均设置于壳体内，静压管设置于壳体外，引压导管的一端与静压传感器连接，引压导管的另一端穿过壳体与静压管连接，静压传感器和加速度传感器均与数据存储单元连接。本发明实现空投试验中降落伞落地前稳降垂直落速测试，降低了空投试验成本，提高了测试的可靠性。
