摘　　要：现役火箭残骸坠落时大多采取传统无控方式,针对该控制方式存在落点散布范围广、疏散搜寻工作量大的问题,提出了火箭残骸坠落的栅格舵控制方式。仿真结果表明,使用栅格舵控制的火箭残骸落在目标点半径6 km范围内的概率高达99.58%,与传统无控方式相比,该方式有效缩小了火箭残骸的理论落区范围,在满足落区控制需求的同时,也减小了火箭弹道设计阶段的理论落区勘察难度。同时以某火箭一级为研究对象的真实飞行试验数据也证明了栅格舵控制方式的有效性和仿真结果的合理性。这种栅格舵控制技术,亦可在火箭可重复使用的发展上发挥作用。The traditional uncontrolled mode is mostly adopted when the wreckage of the rocket in service falls,which has the problems of wide distribution of landing points and heavy workload of evacuation and search.In order to solve this problem,taking thefirst stage of the rocket as the research object,a gridfins control method for the fall of rocket wreckage is proposed.The simulation results show that the probability of the rocket wreckage controlled by the gridfins falling within the radius of the target point 6 km is as high as 99.58%.The rocket primary gridfins guidance control scheme not only meets the requirements of landing area control,but also reduces the difficulty of theoretical area investigation in the stage of rocket trajectory design.The realflight test data of a rocket'sfirst stage also prove the effectiveness of the grid fins control method and the rationality of the simulation results.Compared with the traditional uncontrolled method,this method effectively narrows the theoretical landing area of the rocket wreckage.The widespread application of gridfins control technology can also contribute to the development of reusable rockets.
