Abstract
In order to study the characteristic of pressure container impacted by space debris, the characteristics of pressure container filled with water under hypervelocity impact were studied by test and simulation.The targets were ball pressure containers welded by stainless steel and were charged with water occupying about 80% volume of container and nitrogen of 2.0MPa be-fore test.The water was used to simulate liquid in the pressure container of spacecraft,and the nitrogen of 2.0MPa was used to simulate the work pressure of container.The projectiles were a-luminum spheres,and the impact velocities were about 2.5km/s.The damage models of ball pressure container were obtained by test,the moving characteristic of aluminum sphere in water was simulated.The results showed that the main damage were perforation and burst for ball pressure container filled with water under hypervelocity impact.The fragments generated by pro-j ectile impacting pressure container were decelerated evidently by the water in container which caused no evident damage on the back wall of pressure container.Under the same working pres-sure,the pressure container with low designing pressure would burst more possibly.The study conclusions provided reference for designing and protection from space debris of pressure contain-er of on-orbit spacecraft.关键词
