三维喷管的类型和基本特点在航空、航天领域,轴对称的三维喷管的应用要远远早于二维喷管。但奇怪的是,二维喷管名词的出现却先于三维喷管,因而引起了许多误解。早期的动力装置的排气管、喷管等几乎无一例外地都选择了轴对称的圆截面。近代和现代的活塞式飞机、汽车的排气管,涡桨式飞机、喷气式飞机以及各种导弹的尾喷管也大多为圆截面的。那么,现代飞机的重要组成部分——喷管的基本功能是什么呢?在航空界,涡
Three-dimensional nozzle type and basic characteristics In the field of aviation and aerospace, the application of axisymmetric three-dimensional nozzle is much earlier than the two-dimensional nozzle. But strangely enough, the advent of two-dimensional nozzle nouns preceded the three-dimensional nozzle and caused many misunderstandings. Exhaust pipes, nozzles, etc., of the early power plants, almost invariably chose an axisymmetric circular cross section. Modern and modern piston aircraft, automobile exhaust pipes, turboprops, jets and tail pipes for various missiles are also mostly circular in cross section. So, the important part of the modern aircraft - what is the basic function of the nozzle? In the aviation industry, vortex
