螺旋桨性能的研究因新型飞行器的发展而重新活跃起来,这些飞行器包括电动固定翼飞机、多旋翼电动垂直起降飞行器和倾转旋翼飞行器。这些类型的飞机利用一系列现代螺旋桨,通常具有更先进的平面形状和特征,如下反角,并在传统性能带之外的飞行包线中运行。先进材料(主要是复合材料)的使用、高几何掠角和可变角速度是非定常空气动力学的来源,这通常与叶片的结构响应相结合。来自实验研究的数据大多是历史性的,大多数研究是在1960年之前进行的,当时航空业迅速转向喷气推进。这些研究缺乏颤振边界评估。现代螺旋桨很可能被推向其颤振边界,但迄今公布的实验数据库不足以提供颤振边界评估。本文综述了现有的实验研究的价值和状态的最先进的数值方法的状态,以建立现代研究的螺旋桨失速颤振的要求。
Research on propeller performance has been reinvigorated by the development of new classes of vehicles, ranging from electrically powered fixed-wing aircraft, to multi-rotor electrical Vertical Take-off/Landing (eVTOL) vehicles and tilt-rotor aircraft. These types of aircraft utilise a range of modern propellers, often with more advanced planforms and features such as anhedral, and operate in flight envelopes that are outwith the traditional bands of performance. The use of advanced materials (mostly composites), high geometrical sweeps and variable angular velocities are the source of unsteady aerodynamics, that is often coupled with the blade’s structural response. Data from experimental investigations is mostly historic, with the majority of studies conducted before 1960, when aviation shifted rapidly towards jet propulsion. These studies lack in flutter boundary assessment. Modern propellers are likely to be pushed toward their flutter boundaries, but the experimental database published to-date is insufficient to provide flutter boundary assessment. This review examines the value of the available experimental research and the status of the state-of-the-art numerical methods, in order to establish the requirements for modern research on propeller stall flutter.
