| 摘 要： | 现有的基于四元数的飞机本体运动方程没有完全消除欧拉角。本文推导了气流坐标系与机体坐标系的转换关系,尤其考虑了俯仰角为±90°时的情况。得到了以向量式表示的、完全消除欧拉角的飞机本体运动数学模型。该模型便于面向对象程序实现,并用于大姿态角飞行仿真。

| Abstract: | Existing quarternion-based model of rigid aircraft motion does not totally eliminate eular angles. The transformation between wind- and body-axes coordinate systems, especially for the case of near-vertical flight, was deduced. A new model of rigid aircraft motion, in form of vectors, eular angles totally eliminated, was proposed. The model can be easily realized by object-oriented language and used in near-vertical flight simulation. |
