浅析飞机的大攻角气动问题及其研究方法

A SIMPLE ANALYSIS OF THE AERODYNAMIC PROBLEMS OF THE FIGHTER AIRCRAFT AT HIGH ANGLE OF ATTACK AND THE STUDY METHODS

本文分析了现代战斗机的发展趋势,阐明了进行大攻角/过失速机动的必要性,指出解决至今威胁着飞行安全的失速/尾旋问题仍为当代空气动力学家的重任;论述了各种研究大攻角气动问题的方法之优劣;对我国开展大攻角气动问题研究的技术途径提出了一些建议。

The developing tendency of modern fighter aircraft isanalyzed.The necessity of undergoing high angle of attack/post-stall(PST)maneuvers is explained,and still the heavy responsibilities formodern aerodynamicists to solve the stall/spin problems which havethreaten flying safety up to now is pointed out.The advantages andshortcomings of various methods used for studying the high-angle-of-attack problems are expounded.Finally,some suggestions about tech-nical approaches to study high-angle-of-attack aerodynamic problems inChina are given.
