摘　　要：针对飞机侧滑角不能够精确测量的问题,提出了一种基于GPS的飞机侧滑角校准试飞方法。先在稳定风场空域以垂直三边飞行,得出飞机的真实空速和准确的空域风场数据,再利用在此空域作协调侧滑试飞动作进行侧滑角校准。试验结果证明此校准试飞方法可行有效。Aiming at the problem that the airplane side-slip angel cannot be measured accurately, a lfight test method of the airplane side-slip angel calibration which is based on GPS was proposed. Firstly, the airplane flew in the stable wind ifeld by vertical trilateral mode and the airplane true airspeed and accurate wind ifeld data were gotten. Then, side-slip angle calibration was completed by using coordinated side-slip test movement. The results show the calibration test method is feasible and valid.
