摘要
为提升重复使用运载器(RLV)竞争力精细化设计边界,在融合3颗卫星载荷采集的大气数据基础上,采用大/小尺度扰动分别建模的方法,建立了沿RLV再入飞行轨道的全域参考大气模型,开展了大气密度空间性和季节性(1月、4月、7月和10月)气候变化对跟踪RLV高纬度升力式再入标准轨道的影响分析.结果显示季节性和轨道空间性变化带来的大气密度偏差特性和散布特性,会强烈影响跟踪标准轨道的终端分布特征.这表明引入大气参考模型可以提升RLV性能,降低运行成本.
Abstract
In order to improve the competitiveness of reusable launch vehicles(RLV),a global reference atmospheric model along the RLV reentry trajectory is established by integrating the atmospheric data collected by the three satellite payloads of TIMED,Aura and Envisat and using the method of large-and small-scale disturbance modeling respectively.The effects of atmospheric density spatial and seasonal(in January,April,July and October)climate change on the high-latitude lifting reentry standard trajectory tracking RLV are analyzed.The results show that the characteristics of atmospheric density deviation and dispersion caused by seasonal and spatial changes strongly affect the terminal distribution characteristics of the tracking standard trajectory.This indicates that the introduction of atmospheric reference model can improve the performance of RLV and reduce the operating cost.
