研究了喷流控制飞行器的气动建模与参数估计方法,以某飞船返回舱飞行试验为例,通过辨识得到了返回舱再入过程中的气动导数、喷流力矩放大系数等重要气动参数。该方法是研究喷流干扰效应的一种有效途径,辨识结果有助于提高返回舱姿态控制的准确度。
The aerodynamic modeling and parameter estimation of jet controlled aircraft are studied. Taking the flight test of a spacecraft as an example, the important aerodynamic parameters such as aerodynamic derivative and jet amplification factor are obtained through identification. This method is an effective way to study jet interference effect. The identification result helps to improve the attitude control accuracy of the capsule.
