摘要: 对新型的持续载荷飞行模拟器(SGFS,Sustained G-load Flight Simulator)模拟过失速机动过载的方法进行了研究.针对过失速机动中飞机角运动剧烈的特点,推导了考虑飞机转动带来的附加过载的飞机飞行员过载计算公式.在SGFS过载模拟数学模型中应用此公式,以典型的过失速机动动作.Herbst机动为例,对机动时的飞行员过载进行了仿真研究.仿真中SGFS能够较精确地跟踪输入的飞行员三轴过载指令,最大误差小于0.2g.研究结果表明:过失速机动时飞机转动引起的附加过载不可忽略,同时也表明SGFS可较好地用于对过失速机动飞行员过载的模拟.Abstract: Methods of simulating G-loads in post-stall maneuvers on a novel sustained G-load flight simulator (SGFS) was studied. Considering features of intense angular motion of the aircraft in post-stall maneuvers, additional G-loads generated by the rotation of the aircraft were also counted in the calculation of G-loads on pilot, which was later employed in the mathematical model for SGFS G-load simulation. G-loads on pilot in a typical post-stall maneuver known as Herbst maneuver were simulated by using the model. SGFS tracked 3-axis G-loads command precisely with the maximal error less than 0.2g during the simulation. The results indicate that additional G-loads on pilot generated by aircraft rotation could not be neglected and show SGFS could meet the requirements of post-stall maneuver G-loads simulation.
