摘要
近些年来垂直起降(VTOL)飞行器发展迅速,并获得了一些突破性进展,但仍有许多尚未解决的问题。结合旋翼机和固定翼飞机的优点,提出一种旋翼固定翼复合式飞行器布局方案,兼具优异的垂直起降性能及高速飞行能力,具有转换过渡稳定平滑、可控性强的特点。在该旋翼固定翼复合式布局中,特型旋翼可旋转以提供垂直升力,也可停转、锁定与固定式机翼保持平行,最终转换为固定翼面使得飞机转换为固定翼布局,并在机翼上布置矢量推力装置,实现高速飞行。概念设计研究围绕设计方法、特型旋翼、矢量推力系统等关键技术展开,并开展了平飞模式飞行特性、垂直起降模式飞行特性、航程、航时以及飞行操纵等性能的分析。通过试制小型原理验证机,并对各飞行状态及转换过渡飞行进行飞行试验,验证了该布局的可行性。结合实际算例展开分析计算,验证了该方案设计方法的准确性和实用性。
Vertical takeoff and landing （VTOL） aircraft technology has been developed rapidly in recent years with some breakthroughs and also unsolved issues. A rotary wing and fixed wing compound VTOL aircraft configuration is proposed, which combines the advantages of rotorcraft and fixedwing aircraft. It possesses the performance of VTOL capability and high-speed cruise. And the stability and controllability of conversion flight benefits from this configuration. The multifunctional rotary wing rotates for lift and transforms to a fixed wing surface in high-speed flight while the vectored thrust appliance pro- vides axial thrust. A specific conceptual design method and the key technologies for this type of VTOL aircraft are discussed. The specializations of the conceptual design for airframe aerodynamics, the multifunctional rotary wing, vectored thrust ap- pliance and power system are illustrated. The manipulation theory, flight characters and the performances of horizontal flight mode, vertical flight mode and conversion flight are analyzed. A prototype is manufactured. The results of primary flight tests prove the feasibility of this configuration. And a design example has been analyzed according to this method. The accu- racy and practicality are proved by the results.
