摘 要:
文章通过对火星探测进入轨道的分析，提出了一种以动压为控制目标的开伞控制方法，并借鉴过载-时间控制法的相关思想，结合火星探测进入轨道的特点，研究了该开伞控制法的原理和实现方法。根据火星探路者的实际进入条件，采用该方法的分析结果与实际飞行中的开伞情况基本吻合。[著者文摘]

Abstract:
On the basis of the analysis of the atmospheric entry trajectory for the Mars exploration, a method of the parachute deployment control which was responsible for scheduling the appropriate time to initiate parachute deployment by the dynamic pressure was presented. According to the character of the atmospheric entry trajectory for the mars exploration, and the use for reference of the idea on the method of acceleration - time control, the principle and the algorithm of the parachute deployment control were studied. The analysis result by the method of the parachute deployment control under the Mars Pathfinder actual entry condition was in agreement with the flight result.[著者文摘]
