Abstract

In order to study the inspiration capacity,impact power and erosion effect of underwater self-excitation inspiration pulsed jet equipment，a number of impact performance tests of two equipment with different chamber length, chamber and under nozzle diameter in inspiration and non-inspiration conditions were conducted. The results show that confining pressure and under nozzle diameter has great influence on the inspiration capacity, as the confining pressure is increase, the inspiration capacity is decrease and there exists an optimum range of under nozzle diameter. The confining pressure and the under nozzle diameter has small influence on the best impact range of equipment. The impact power of target center and first lap increases significantly compared with the non-inspiration condition, so the equipment produces better shaped charge effect. The variation regular of target center and each lap is diffferent along with the variation of under nozzle diameter. The influence of the under nozzle diameter on the erosion depth, erosion surface area and erosion volume is also different.
