The invention provides an amphibious vehicle body water sailing drag reduction device using supercavitation. The device comprises a tail gas collecting device, a compressed gas storage device, an expansion unit, a constant temperature device, a gas conveying assembly and a supercavity emitting device. The tail gas collecting device collects and filters tail gas generated by an amphibious vehicle engine, and the tail gas is compressed and stored in the compressed gas storage device. During use, gas is subjected to pressure and temperature adjustment through the expansion unit and the constant temperature device, then the gas is conveyed to the supercavity launching device arranged on the bow of the amphibious vehicle body through the body conveying assembly, and the gas with the needed stable pressure and temperature is emitted outwards through holes in the supercavity launching device; and supercavities for reducing resistance are formed around the holes. By means of the amphibious vehicle, resistance borne by the amphibious vehicle in the water sailing process can be reduced.
本公开提供了一种利用超空泡的水陆两栖车体水上航行减阻装置。该装置包括尾气收集装置、压缩气体储存装置、膨胀单元、恒温装置、气体输送组件、超空泡发射装置。尾气收集装置收集和过滤水陆两栖车发动机产生的尾气,压缩存储在压缩气体储存装置中。使用时,气体通过膨胀单元、恒温装置进行压力、温度调节,然后经由体输送组件输送到设置在水陆两栖车体的艏部的超空泡发射装置,具有所需压力和温度稳定的气体通过超空泡发射装置上的孔洞向外发出,在孔洞周围形成用于减阻的超空泡。使用本发明能够减小水陆两栖车在水上航行过程中所受的阻力。
