摘要

为了提高刚性同轴转子在悬停和高速巡航条件下的性能,本研究开发了一种新颖的气动优化方法,可区分上部和下部转子。该方法利用升力线和重新制定的粘性涡流粒子法(rVPM),对同轴转子的复杂尾流场进行建模,并准确评估叶片上的气动载荷。通过创新的求解器对几何特性进行优化,如平面配置和非线性扭转,该求解器集成了模拟退火和奈德-梅德算法,确保了快速和全面的优化结果。对比分析表明,这些量身定制的几何调整大大提高了两种运行状态下的效率,超过了传统方法。这项研究为解决同轴转子设计中不同飞行状态带来的各种空气动力学挑战提供了一个战略框架。

An rVPM-Based Aerodynamic Hybrid Optimization Method for Coaxial Rotor with Differentiated Upper and Lower Blades in Both Hover and High-Speed Cruising States
To enhance the performance of rigid coaxial rotors across both hovering and high-speed cruising conditions, this study develops a novel aerodynamic optimization method that differentiates between the upper and lower rotors. Utilizing the lifting line and reformulated viscous vortex particle method (rVPM), this approach models the complex wake fields of coaxial rotors and accurately assesses the aerodynamic loads on the blades. The optimization of geometric properties such as planform configuration and nonlinear twist is conducted through an innovative solver that integrates simulated annealing with the Nelder–Mead algorithm, ensuring both rapid and comprehensive optimization results. Comparative analyses demonstrate that these tailored geometric adjustments significantly enhance efficiency in both operational states, surpassing traditional methods. This research provides a strategic framework for addressing the varied aerodynamic challenges presented by different flight states in coaxial rotor design.
