The invention discloses an aircraft attitude angle calculation method based on coordinate transformation. The method is characterized by comprising the steps of establishing an intermediate coordinatesystem O-X1Y1Z1, a geodetic coordinate system O-XYZ and a machine body coordinate system O-X2Y2Z2; realizing the conversion between a geodetic coordinate system and an airframe coordinate system through an intermediate coordinate system according to the conversion between a roll angle and a pitch angle of an aircraft, so that the attitude angles of the aircraft under different coordinate systemsare calculated. Meanwhile, corresponding oil quantity data query under the geodetic coordinate system and the airframe coordinate system is performed by using an oil quantity database of one coordinate system. By means of the operation, quick aircraft attitude angle calculation and oil quantity query under the corresponding attitude angle are achieved.

    一种基于坐标转换的飞机姿态角计算方法,其特征在于,建立中间坐标系O‑X1Y1Z1、大地坐标系O‑XYZ和机体坐标系O‑X2Y2Z2,以飞机滚转角和俯仰角的变换,通过中间坐标系实现大地坐标系与机体坐标系之间的转换,从而进行飞机不同坐标系下的姿态角计算,同时使用一个坐标系的油量数据库,进行大地坐标系和机体坐标系下对应的油量数据查询。本发明通过上述操作实现了快捷的飞机姿态角计算及对应姿态角下的油量查询。
