Abstract: High velocity impact on long duration and large size spacecraft by meteoroid and space debris is a threat to spacecraft safety operation,Which can in turn lead to significant damage and catastrophic failure.In order to conduct an accurate assessment of spacecrat module wall damage impacted by debris cloud created by meteoroids and space debris high velocity impact on bumper,the velocity characterization of debris cloud must be known.Based on the principles of momentum and energy conservation,the analysis model of debris cloud velocity characterization is presented in this paper.The velocity characterization of debris cloud is calculated,the travel velocity and spread angle of debris cloud material is obtained.
