| Abstract: | This paper studies the effects of the hypervelocity impact on typical Whipple Shields at cryogenic temperatures.The cryogenic setup,installed in the target chamber of a two-stage light-gas gun,is developed to cool the targets down to-150 ℃ with liquid nitrogen to provide the essential condition for tests of shield structures at cryogenic temperatures.Several hypervelocity impact tests were carried out at cryogenic temperatures,and the impact results are compared with those obtained at room temperature,including the characteristics of bumper penetration,debris cloud,and rear wall damage.The ballistic limit curves of typical Whipple shields at cryogenic temperatures are obtained. |
