AC500飞机尾旋特性飞行试验研究

Research on AC500 Aircraft Spin Flight Test

飞机机翼翼型选择、修型和优良的气动布局设计是保证飞机具有良好尾旋特性的关键。本文在详细介绍尾旋机理及适航合格审定要求的基础上,采用飞行试验方法对AC500单发正常类飞机尾旋特性进行了研究,结果表明:AC500飞机不会由失速无意中自动进入尾旋,必须经有经验的驾驶员有意操纵才能进入,未经培训的驾驶员难以操纵进入,且进入后容易改出。本文推荐的试飞方法可供其他小型民用飞机型号合格审定尾旋科目飞行试验借鉴。

Based on the spin mechanism and airworthiness certification requirements, spin characteristics of single engine normal category aircraft of AC500 are investigated by flight tests. Flight test results show that AC500 cannot fall into spin easily unless intended fly into spin by the experienced and trained pilot. It is hard to fall into spin for the untrained pilot and easily recover even if unintentional falling into. The flight test method recommended in this paper can be used as a reference for providing other small single engine aircraft spin certification tests.
