The invention provides a cavity air compression type underwater combined load reduction device which comprises a separated fairing, a navigation body, a hard polymer foam layer, a buffer device and a cavitator, the buffer device is used for buffering the acting force between the navigation body and water when the navigation body enters the water, the front end of the separated fairing is conical, and the cavity air compression type underwater combined load reduction device further comprises a side fairing; the fairing side wall comprises a fairing body, the front end and the rear end of the fairing body are provided with a high-pressure air cavity and a sub-high-pressure air cavity respectively, the high-pressure air cavity and the sub-high-pressure air cavity are connected through a pressure reducing hole, the front end of the fairing body is provided with a plugging device for opening or closing the pressure reducing hole, and the buffering device is located in the high-pressure air cavity. Air cushion type buffering is added on the basis of a traditional buffering device, and the head of the navigation body can be further protected against damage.
本发明提供一种空腔体压气式入水组合降载装置,包括分离式整流罩、航行体、硬质聚合物泡沫层、缓冲装置和空化器,缓冲装置用于缓冲航行体入水时航行体与水之间的作用力,分离式整流罩的前端呈锥形,还包括侧边整流罩;整流罩侧壁包括整流罩主体,整流罩主体的前后端分别设有高压空气腔和次高压空气腔,高压空气腔和次高压空气腔间通过降压孔连接,且整流罩主体的前端安装有打开或封闭降压孔的封堵装置,缓冲装置位于高压空气腔内。本发明在传统的缓冲装置的基础上增加了气垫式缓冲,能够进一步保护航行体的头部不被破坏。
