摘　　要：在中国空气动力研究与发展中心超高速所的超高速碰撞靶上进行了-110°、20°和150°温度条件下铝质Whipple防护屏在4.0～6.0km/s范围内的超高速撞击试验。试验获得了该Whipple防护屏在三种温度条件下的弹道极限参数及其变化规律,结果表明：在本文试验状态下,温度对Whipple防护屏弹道极限参数的影响不显著;试验得到的弹道极限参数均大于Christiansen方程的预测值。Hypervelocity Impact tests have been conducted to study the effect of temperature on the performance of the Whipple shields at hypervelocity impact range of HAI, CARDC. Impact velocity varies from 4.0km/s to 6.0km/s, and the temperature of the Whipple shields are set to - 110℃, 20℃ and 150℃. The test results suggest that the ballistic limits are mildly affected by the variation of temperature, and those ballistic limits derived from the tests are slightly greater than those predicted by Christiansen equations.
