| Abstract: | 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. |
