摘　　要：飞机在地面停机时会受到恶劣天气影响,对飞机停机情况的气动力研究是评估停机安全的关键。为了分析典型布局民用飞机的地面侧风气动力差异,确定典型系留载荷,针对两种典型布局民用飞机,在风洞中采用缩比模型和固定地板模拟飞机停机,测量飞机在0°~180°地面侧风情况下的气动力,进一步通过部件组拆测量方法分析尾翼部件气动力耦合效应;确认垂尾平尾布局耦合效应是在侧风情况下低平尾布局飞机抬头力矩较大、以及高平尾布局飞机抬头力矩较小的原因,采用工程估算方法得到后倾翻情况的前起落架系留载荷。结果表明:俯仰气动力差异导致低平尾布局飞机的前起落架系留载荷明显增加,而对高平尾布局飞机影响较小。The aircraft is impacted by severe weather on parking apron,and the aerodynamic research of parking is important for parking safety. In order to analyze the aerodynamic difference of typical-layout civil aircraft induced by ground cross-wind,and determine the typical tie-down loads,the scale mode and fixed ground plate in wind tunnel are used to simulate the aircraft park aiming at two typical-layout civil aircraft,the aerodynamic forces of aircraft which induced by cross-wind with the angles from 0° to 180° are measured. The disassemble test method is adopted to analyze the empennage aerodynamic coupling. The reasons of large pitching moment of high horizontal tail layout and small pitching moment of low horizontal tail layout at cross-wind research are confirmed in the condition of the empennage aerodynamic coupling. The engineering estimation method is used to obtain the nose landing gear tie-down loads at rear tipping condition. The results show that the deference of aerodynamic characteristics can increase the nose landing gear tie-down loads of low horizontal tail aircraft,and is of less influence on high horizontal tail aircraft.
