摘要
根据适航条款的要求,归纳出民机横航向稳定性的试飞要点。对国产某型支线客机的横航向稳定特性进行了评定研究,提出了合适的飞行试验方法,并进行了飞行试验评定。试验结果表明,该试验方法所验证的本体阻尼特性满足适航审定的最低要求,而且通过自动偏航阻尼器的增稳作用,飞行品质有显著提升,飞行员更易于完成横航向控制的飞行任务。
Key points for lateral and directional stability of civil aircraft are summarized according to the requirements of airworthiness regulations. Lateral and directional stability of a domestic regional jet aircraft was evaluated and studied,proper flight test methods were presented and evaluated through flight test. Flight test results show that the experimental method of otology damping characteristics meet the minimum standards for airworthiness certification. The flying quality has been significantly increased through the stability augmentation of automatic yaw dampers,and it is easier for the pilot to complete the flight mission for lateral and directional control.
