摘要
首先简要概述了物面压力分布与物面外形之间的关系,进而介绍了飞机外形设计中经常用到的一类曲线-二次曲线,并推导出二次曲线G2连续的条件和公式,最后介绍了在CATIA中运用Formulas功能实现二次曲线G2连续的方法,并以实例将该方法应用到飞机外形设计中。
In this paper, the correlation between surface pressure distribution and body geometry is addressed first, followed by an brief description for conic curve used widely and frequendy in aircraft geometry design. A G2 continuous condition expression for conic curve is given. (32 continuous conic curve is realized via CATIA-based formulas, and applied to aircraft geometry design.
