摘要: 针对分布式动力串列翼飞行器在大迎角下的气动/推进耦合特性,开展了系统的地面车载试验研究。通过自主研发的高精度车载测试平台,对分布式动力翼段及全机串列翼布局模型进行了多转速、多迎角状态下的气动性能测试,获取了详实的耦合升力、耦合阻力和俯仰力矩数据。研究揭示了涵道风扇转速对失速迎角、最大耦合升力及纵向静稳定性的显著影响,并发现串列翼布局中存在明显的前后翼气动干扰现象。进一步提出通过前后涵道风扇转速差动调节静稳定性的方法,有效扩展了飞行器的稳定迎角范围,为分布式动力垂直/短距起降飞行器的气动设计与控制提供了重要的试验依据和数据支持。

Abstract: A systematic ground-based vehicle-mounted test study was conducted to investigate the aerodynamic/propulsion coupling characteristics of a distributed propulsion tandem-wing configuration aircraft at high angles of attack. Utilizing a self-developed high-precision vehicle-mounted testing platform, aerodynamic performance tests were performed on both a distributed propulsion wing section and a full tandem-wing configuration model under various rotational speeds and angles of attack. This yielded comprehensive data on lift, drag, and pitching moment. The research revealed the significant influence of ducted fan rotational speed on the stall angle of attack, maximum lift coefficient, and longitudi-nal static stability. Notable aerodynamic interference effects between the front and rear wings were also identified. Furthermore, a method for adjusting static stability through the differential rotational speeds of the front and rear duct-ed fans was proposed. This method effectively expanded the stable angle-of-attack envelope of the aircraft, providing crucial experimental evidence and data support for the aerodynamic design and control of distributed electric verti-cal/short take-off and landing (eVTOL/STOL) aircraft.
