摘要
根据在国外试飞的经历,介绍并分析了单旋翼带尾桨直升机旋翼转速包线拓展试飞有关内容。首先根据该试飞科目要求来源,结合相关适航规范确定试验点;其次介绍了科目的试飞基本方法,并分析了无动力时初始试验点的选择和旋翼转速的控制;最终进行了空中演示试验并对试验结果进行了分析,所得结论为该科目的试飞提供了参考。
This paper analyzes the main rotor speed envelope expansion flight test about a single main rotor and tail rotor helicopter based on the author＇s experiences in flight test abroad. First the flight test points required for this flight test was decided by the correlation airworthiness specifications and the sources about requirements for rotor speed envelope expansion flight test. Then the generally method for rotor speed envelope expansion flight test was presented,also the analysis of the choice for initial flight test point and rotor speed control in the power off was addressed. Lastly,the rotor speed envelope expansion demonstration flight test was implemented and the results of the flight test were analyzed. All of these will give a useful reference for the flight subject.
