摘要
Abstract
Aerodynamic longitudinal static stability characteristics,hypersonic lift-to-drag ra-tio characteristics under trim angle of attack,and off-set location placement of gravity center for spherical cap segment-reversing cone capsule configuration are studied through Multi-point/objec-tive Design Optimization technique combined numerical parallel simulation methods.Contrary re-lations are presented between the aerodynamic static stability and the other two characteristics. Aerodynamic static longitudinal stability is improved as trimmed lift-drag ratio decreased and off-set location of gravity center increased,whereas,increasing trimmed lift-drag ratio or decreasing offset location of gravity center means worse static stability.The method introduced in the paper shows some guiding significance for the design of reentry capsule.关键词
