研究了高平尾布局飞机的气动特性。使用失速改出伞是飞机改出深失速的重要途径,但如何确定失速改出伞的关键参数(阻力面积等)却没有现成的方法。以ARJ21-700飞机为例,分别使用公式分析法、类比法综合估算出失速改出伞的关键参数,通过模型自由飞和模拟仿真分析验证其具有足够效能将飞机改出深失速状态。形成了一套新机失速改出伞的设计方法和关键数据图表,可供其他型号飞机失速改出伞的设计研制使用。
The aerodynamic characteristics of aircraft with high level tail are studied. The use of stalled umbrella out of the aircraft is an important way out of the deep stall, but how to determine the stall stalls out of the umbrella of the key parameters (resistance area, etc.) there is no ready-made method. Taking ARJ21-700 as an example, the key parameters of stalling umbrella were estimated by using formula analysis and analogy respectively. The free flight and simulation results show that the ARJ21-700 has enough efficiency to change the aircraft out of deep stall state. Formed a set of new machine stalling umbrella design method and key data charts for other types of aircraft stalling umbrella design and development.
