现代模拟技术的发展,已经完全可以做到实验室中比较逼真地模拟复杂的宇宙和航空飞行。飞行模拟常常要显示和测量飞行器在三维空间的姿态运动,一般都是通过解飞行器在三维空间的角运动方程,经过欧拉角速度方程转换,求出欧拉角(即飞行器相对于地直座标系的姿态角,如φ,θ,φ),控制飞行模拟转台或天—地景投影系统,以模拟飞行器在空间的实际姿态运动。 欧拉角速度方程存在奇异性(即解的不连续性和非唯一性),相对应的三轴转台存在“自锁”现象,单独使用,不能模拟飞行器的全姿态运动,而宇宙飞行,卫星姿态控制、双机格斗空战等模拟,往往都要求在大角度全姿态范围内运动,要显示和模拟全姿态运动,则必须
The development of modern simulation technology has been able to simulate the complicated cosmic and aeronautical flight relatively realistically in the laboratory. Flight simulations often show and measure attitude movements of an aircraft in three-dimensional space. Generally, the Euler angles (that is, the relative position of the aircraft relative to the ground coordinates) are obtained by solving the equation of angular motion of the aircraft in three-dimensional space through Euler angular velocity equations. Department of attitude angles, such as φ, θ, φ), control flight simulator turntable or day - landscape projection system to simulate the actual attitude of the aircraft in space movement. The Euler angular velocity equation has singularity (ie, solution discontinuity and non-uniqueness). The corresponding three-axis turntable has the phenomenon of “self-locking”. It can not simulate the full attitude movement of the aircraft, but the space flight and the satellite attitude Control, dual combat air combat and other simulations, are often required to move in a wide range of full attitude to display and simulate full attitude movement, you must
