摘要
推导了存在风切变时在气流坐标系(相对风轴系)中飞机质心空间三维运动方程和在体轴系中飞机的旋转运动方程。指出了按航迹坐标系(绝对风轴系)建立移动运动方程时的某些不便之处。为了进行比较,给出了分別应用上述两组运动方程计算的波音-727飞机起飞飞行轨迹的不同结果。
In this paper, the special three dimensional equations of motion of the mass center of the aircraft with windshear in the air—axes system (relative wind—axes system) are derived, and the equations of rotational motion of the aircraft in the body—axes system are presented also. Some inconvenient factors are pointed out if the foundation of the forces equations is finished in the path—axes system (absolute wind—axes system ). In comparison, the different results from two sets of equations of motion respectively for take—off trajectories of Boeing—727 aircraft are presented.
