摘要
目前国内民用运输机执行纵向静稳定性试飞时主要采用稳态法,而此方法存在试验时因飞行高度变化过大过快而难以采集足够试飞数据的缺点。针对FAA咨询通告AC25-7C中提出的两种关于纵向静稳定性的试飞方法进行对比分析,从而考察平飞加减速法的可执行性,分析传统的稳态法和新的平飞加减速法的优缺点和实际飞行试验时的可行性,得出初步结论为平飞加减速法有其独特的优点,主要适用于能平飞配平的试验点,而对于飞机发动机设置于最大推力和慢车推力试验点的适用性,还需通过试验进一步考察确定。
The conventional way to perform the longitudinal static stability flight test for civil transport aircraft is stabilized method. While the main disadvantage of the stabilized method is insufficiency of flight test data due to the fast and large altitude changing. This article focuses on the advantage and disadvantage about the applicability of the longitudinal flight test methods proposed by AC25- 7C,which are stabilized method and acceleration- deceleration method. The initial conclusion is that the acceleration- deceleration method can apply to the level flight trim test points,and the method is still to be confirmed by simulator test and flight test during the applicability of the maximum thrust and idle thrust test points.
