摘　　要：通过载人离心机在地面上持续模拟飞机全剖面飞行过载特性是提高飞行员抗荷能力的重要手段。随着有人驾驶飞机机动性能的大幅度提升,精确分析其飞行过载特性,并将之转换为离心机控制指令以实现持续有效飞行过载特性模拟是极其困难的。首先建立飞机准确的运动学和动力学方程,据此详细分析了飞机全剖面飞行时的过载特性;然后分析了载人离心机的机械和运动特性;再利用大地坐标系、机体坐标系、飞行员坐标系之间的转换关系,获取飞机过载特性到载人离心机控制指令的提取方法;最后针对含旋转、滚转、俯仰的三轴离心机,开展了面向全飞行剖面的飞行姿态、过载计算、离心机控制指令的数字仿真实验,实验结果表明所提的飞机全剖面飞行持续过载模拟方法是可行和有效的。It is an important means to improve the anti-G ability of pilots to simulate the flight G-load characteristics of aircraft in full envelop flight on the ground through centrifuge.With the great improvement of maneuvering performance of manned aircraft,it is extremely difficult to accurately analyze its flight G-load characteristics and convert them into centrifuge control instructions for continuous and effective flight G-load characteristics simulation.The exact kinematics and dynamics equations of the aircraft were established,the corresponding G-load characteristics of the aircraft in full envelop flight were analyzed in detail.Then the mechanical and kinematic characteristics of the centrifuge were analyzed.Then,the transfer relationship between the earth coordinate system,the aircraft body coordinate system and the pilot coordinate system were used to obtain the extraction method of the aircraft G-load characteristics to the centrifuge control command.Finally,for a threeaxis centrifuge with rotation,roll and pitch axis,the digital simulation experiments of flight attitude,G-load calculation and centrifuge control commands for the full flight envelop were carried out.The experimental results show that the proposed simulation method of G-load in full envelop flight of aircraft is feasible and effective.
