The invention provides a parachute opening device of a drop sonde, and belongs to the technical field of airborne meteorological detection and sounding equipment.The parachute opening device comprises a parachute cover, a parachute cabin used for containing a parachute, a fusing device arranged at the bottom of the parachute cabin and a base, the parachute, a nylon rope and a compression spring are arranged in the parachute cabin, and when the parachute opening device opens the parachute, the fusing device is used for fusing the parachute. And after the fusing device fuses the nylon rope, the parachute pops up from the parachute cabin under the action of the reset elastic force of the pressure spring to realize parachute opening. The parachute opening device of the drop sonde is of an active ejection type parachute opening structure, resetting of the compression spring is controlled through fusing of the fusing device so that the parachute can be ejected out through the reset elastic force of the compression spring, the parachute opening device is simple in structure, the parachute opening process is not affected by the environment and the landing posture, and the parachute opening efficiency is improved. The parachute opening success rate is high, the detection loss height is small, and the influence on flight safety after the sonde opens the parachute is reduced.
本申请提供了一种下投探空仪的开伞装置,属于机载气象探测、探空设备技术领域,所述开伞装置包括伞盖、用于容纳降落伞的伞舱、设置在伞舱底部的熔断装置以及底座,所述伞舱内设有降落伞、尼龙绳以及压簧,所述开伞装置开伞时,熔断装置熔断尼龙绳后,所述降落伞在压簧复位弹力的作用下弹出伞舱实现开伞。本申请所提供的下投探空仪的开伞装置为主动弹射式开伞结构,通过熔断装置的熔断控制压簧的复位以利用压簧复位的弹力使降落伞弹出,该装置结构较为简单,开伞过程不受环境和降落姿态的影响,开伞成功率高、探测损失高度小、降低了探空仪开伞后对飞行安全的影响。
