The invention relates to an active load reduction structure of an aircraft. The active load reduction structure comprises an aircraft head, an aircraft middle section, an aircraft tail section, an airinjection rectifying valve, an air injection on-off valve and a high-pressure air cylinder. The air injection rectifying valve is located in the center area of the aircraft head and is a device for injecting uniform high-pressure air. The air injection on-off valve is located on the rear portion of the air injection rectifying valve, is connected with the air injection rectifying valve and the high-pressure air cylinder, controls on-off of air flow and is directly controlled by an aircraft air injection control system. The high-pressure air cylinder is positioned at the rear part of the air injection on-off valve and stores all high-pressure air required for generating a supercavity. The supercavitation technology is applied to load shedding in the high-speed underwater entry process of the aircraft, so compared with a traditional buffer head cap and a load shedding head type load shedding technology has a more excellent supercavitation technology load shedding performance. High-pressure compressed air serves as an air source, so compared with fuel gas injection load reduction, the structure is more compact and smaller and is more suitable for being applied to small and medium-sized underwater vehicles.
本发明涉及一种航行器主动降载结构。包括航行器头部,航行器中段,航行器尾段,喷气整流阀,喷气通断阀和高压气瓶部分。其中,喷气整流阀位于航行器头部中心区域,为喷射出均匀高压气体的装置。喷气通断阀位于喷气整流阀的后部,连接着喷气整流阀和高压气瓶,控制着气流的通断,受航行器喷气控制系统的直接控制。高压气瓶位于喷气通断阀的后部,储存着产生超空泡所需要的全部高压气体。本发明将超空泡技术应用于航行器高速入水过程的降载问题,相比于传统的缓冲头帽和降载头型降载技术具有更优异的降载性能。本发明以高压压缩空气作为气源,相比于燃气喷气降载,系统更为紧凑小巧,更适合应用于中小型水下航行器。
