本文综述了近20年来国外气动弹性力学发展情况和远景。概括介绍了三个问题,一是结构模态参数:有限单元法在模态参数分析方面取得的成就和有待解决的问题,以及高性能微型计算机给地面模态试验带来的巨大进步和前景;二是飞机气动弹性力学:跨音速空气动力学的进展和要研究的课题,风洞和飞行试验技术的现状和展望,以及颤振主动抑制的效果及其发展前途;三是直升飞机和发动机的气动弹性力学:旋翼和叶栅在空气动力学和动态特性方面的现状和发展趋势。
This paper reviews the development and prospects of aeroelasticity in foreign countries in recent 20 years. Three problems are summarized. One is the modal parameters of the structure: the achievements and problems to be solved by the finite element method in modal parameter analysis, and the tremendous progress and prospect brought by the high performance microcomputers to the ground modal test; Second, the aeroelastic mechanics of aircraft: the progress of transonic aerodynamics and the subject to be studied, the current situation and prospect of wind tunnel and flight test technology, the effect of active suppression of flutter and its development prospects; third, helicopter and engine Aeroelasticity Mechanics: Current Status and Trends in Aerodynamics and Dynamics of Rotors and Cascades.
