The high-speed impact of micro-meteors and space debris threatens the long-life, safe operation of large-size spacecraft, causing serious damage and catastrophic failure. In order to accurately estimate the damage to the bulkhead caused by the debris cloud generated by the micro-meteors and the space debris high-speed impact shield, the velocity characteristics of the debris cloud must be determined. Based on the impulse and energy conservation, the paper established the model of the velocity characteristics of debris and studied the velocity characteristics of the debris cloud. The propagation rules of the debris cloud and the variation of spray angle of the debris cloud with the projectile impact velocity were obtained.
