半倾转构型是电驱动垂直起降飞行器(Electric vertical take‑off and landing, eVTOL)的一种常用构型,因此需要对其总体参数设计规律、总体参数优化方法以及过渡飞行功率特性进行研究。首先,提出了一种使用纵向配平框架的半倾转构型性能算法,采用升力旋翼和平尾融合算法解决操纵冗余问题。然后,通过试验数据对比,验证了算法的精度。接下来,使用该性能算法并结合重量模型,分析了各项总体参数、电池能量密度的变化对空机重量、重量效率的影响,并针对特定需求得到了一套满足要求的总体参数。最后,使用半倾转构型性能算法对过渡状态下的功率、迎角、加速度进行扫描,通过分析计算结果,定性选择过渡路径,并通过优化加速度降低过渡过程的能量消耗,得到了过渡过程中剩余功率的变化趋势,为半倾转构型eVTOL的设计与工程研制提供了可参考的研究思路。
The lift‑tilt configuration represents a prevalent architectural solution for electric vertical take‑off and landing (eVTOL) aircraft. Consequently, systematic investigations into its general parameter design principles, optimization methodologies, and transition flight power characteristics are imperative to inform the design process. This paper proposes a performance analysis algorithm for lift‑tilt configurations based on a longitudinal trim framework, wherein a lift rotor‑horizontal tail fusion algorithm is developed to address the control redundancy issue. The predictive accuracy of the proposed algorithm is validated through comparison with experimental data. Subsequently, by integrating this performance algorithm with a weight estimation model, the influences of general parameter variations and battery energy density on empty weight and weight efficiency are quantitatively analyzed, yielding a set of general parameters that satisfy specific mission requirements. Furthermore, comprehensive parametric sweeps of power, angle of attack, and acceleration during the transition regime are conducted utilizing the proposed algorithm. Through detailed analysis of the computational results, the transition trajectory is qualitatively determined, and the energy consumption during the transition phase is minimized via acceleration optimization. Additionally, the variation trend of excess power throughout the transition process is characterized, thereby providing a systematic research framework and technical reference for the conceptual design and engineering development of lift‑tilt eVTOL aircraft.
