摘要:二十世纪最重大的发明之一就是飞机;人类自古以来就梦想着能像鸟儿一样在天空中翱翔。而两千多年前中国人发明的风筝虽然不能把人带上天空,但它也应该算飞机的鼻祖了。现在随着科技的不断发展,飞上天空早已成为常见的事了,飞机也有直升机和固定翼飞机两种。飞机为人类的进步与发展插上了翅膀,将人们的活动范围从陆地、海洋扩展到天空,并且越飞越高、越飞越快、越飞越远,创造了人类历史上一个又一个辉煌,并对社会生活的各个方面产生了和正在产生着极其巨大的影响。本文对直升飞机的攻角、迎角阻力、平稳飞行力学状态进行了分析,对固定翼飞行器的攻角飞行、飞行阻力进行分析,并用这些参数描述主要战技指标,评价战机的优越性性。

Abstract: one of the great inventions of the 20th century was the airplane;Human beings have long dreamed of flying in the sky like than two thousand years ago, a kite invented by the Chinese could not bring people to the sky, but it should also be the granddaddy of the , with the development of technology, flying into the sky has monplace, with helicopters and fixed-wing plug in the wings for human progress and development, to expand the activities of the people from the land, sea to the sky, and the fly higher and higher and faster, the fly far, created the human history one after another brilliant, and on every aspect of social life and is having a huge this paper, the Angle of attack of the helicopter, Angle of attack resistance, steady state of flight mechanics are analyzed, and the Angle of attack of the fixed wing aircraft flight, flight resistance is analyzed, and these parameters describe the technical indicators, evaluate the superiority of aircraft.

一、直升飞机飞行原理

直升机能飞上天的原理是什么? 要想理解它必须先理解1600年伯努利发现的"[color=Blue]伯努利原理[/color]"
