摘要
Abstract
Supersonic civil aircraft has significant changes in aerodynamic layout and design compared to subsonic civil aircraft,which will bring new risks and make some provisions of the current regulations inapplicable.By con-ducting a qualitative analysis of CCAR Part 25 and the special conditions while using computational fluid dynamics(CFD)methods,the aerodynamic characteristics of a small aspect ratio,large sweep angle supersonic civil aircraft in low-speed conditions are analyzed.The safety intent behind the minimum flight speed mentioned in the superson-ic civil aircraft special conditions is revealed through a combination of qualitative and quantitative analysis.The re-sults show that the stall speed reference defined by CCAR Part 25 is not applicable to supersonic civil aircraft.Su-personic civil aircraft adopt the minimum flight speed and zero climb rate speed as new speed references to ensure stable flight while still having climbing ability.关键词
