本文介绍了笔者在静气动弹性效应的理论与实验研究中的若干进展。静气动弹性研究涉及作用于飞行器的气动力与结构变形的相互作用,是研究飞行器的风洞试验数据和飞行试验数据相关性的一个重要方面。文中讨论了在进行静气动弹性分析时对一些问题的处理,并对风洞试验模型及某型导弹进行了计算,结果表明:对于所选算例,结构变形使升力线斜率降低,压心前移。 This article introduces some progresses in the author’s theoretical and experimental researches on static-dynamic elastic effect. Static-dynamic research on aeroelasticity involves the interaction of aero-dynamics and structural deformation acting on the aircraft. It is an important aspect to study the correlation between the wind-tunnel test data and the flight test data of an aircraft. In the paper, some problems are dealt with in static-dynamic elasticity analysis. Wind tunnel test model and some missile are calculated. The results show that for the selected example, the deformation of structure causes the slope of lift line to decrease, shift.
