Aerothermodynamics Research for Long-March Reusable Launch Vehicle

摘要

In order to strengthen the innovative competence of China aerospace transportation system continuously and meet the needs of international space transportation market in the future, CALT should take account of the research for system themes and key technologies for Reusable Launch Vehicle (RLV), which is one of the options after the new generation of Long March (LM) series launch vehicles in the future. At present, the first step for RLV of LM is to be rocket-powered, vertical taking-off, horizontal landing, partially reusable two-stage-to-orbit (TSTO). The ultimate objective of LM launch vehicles is single-stage-to-orbit (SSTO). Aerothermodynamics, especially for orbiter glided entry, is the one of the main key technologies for RLV. According to the request of the first generation partially reusable LM RLV, carry out research on the key Aerothermodynamics problems, which include reusable aerodynamic configuriation design, glided re-entry aerothermodynamics characteristic, wind tunnel experiment technologies and numerical simulation technologies, flight demonstration technologies and aerodynamic database management technologies. Based on these, we provide the winged-body aerodynamic shape which meets system request and flight mission, studying the complicated aerodynamic phenomena and improve the ability of predicting aerodynamic characteristic, improving the high capability ground wind tunnel experiment technologies and numerical simulation technologies and utilizing modern database technologies to build aerodynamic data management database for RLV and form the aerodynamic design data book for RLV ultimately.
