Effects of Spatial and Seasonal Climatic Characteristics of Atmospheric Perturbation on RLV Lifting Reentry Flight
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.
