Development Aerodynamic Technology for Deep Space Entry/Re-entry Exploration
In response to the aerodynamic technology development requirements for deep space ex-ploration entry or re-entry vehicles,China has,since 2011,achieved numerous significant scien-tific and technological breakthroughs over the last 13 years.These achievements encompass light-weight small-sized aerodynamic configuration design,simulation of high temperature complex cross-basin flow coupling effect,prediction and verification of dynamic characteristics of short blunt bodies,as well as research on special aerodynamic issues.Such progress has effectively supported the successful implementation of major lunar exploration and Mars exploration mis-sions.Look ahead,in preparation for deep space exploration missions such as Mars sample re-turn,Jupiter system exploration,and edge-of-the-solar-system exploration,China must advance research into atmospheric-assisted orbit modification technologies,complex effects simulations and testing technics of complex effects of various celestial body atmospheres,and advanced flight measurement and inversion technologies.This paper reviews the evolution of China's aerody-namic technology for deep space entry/re-entry vehicles,with particular emphasis on the aerody-namic technology achievements of Chang'e-5/Chang'e-6 return capsule and the Tianwen-1 lan-der.Finally,based on the future prospects of deep space exploration projects,this paper analyzes the developmental needs for relevant aerodynamic technologies.
