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 aircraft side slip angle can not be accurately measured, a GPS-based test method for calibrating the side slip angle of the aircraft is proposed. First of all, in a stable wind farm airspace should be flown vertically to get the real airspeed of the aircraft and the accurate airspace wind farm data. Then, the side slip angle should be calibrated in this airspace to coordinate the side slip test. The test results prove that this calibration test method is feasible and effective.
