摘要
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 high tail（ or T tail） aircraft aerodynamic characteristics was analyzed. Anti-stall parachute is an effective way to recover an aircraft from deep stall. But the key parachute parameters（ drag area,parachute cord length） determination is uncertain. In this paper,using ARJ21-700 airplane as an example,these parameters are estimated by combining the formula analysis results and comparison results.Then its validity is proved with the use of model free-flight test and model simulation results. A new antistall parachute method are developed and can be used in the anti-stall parachute design of other aircraft.
