【摘要】 针对西北工业大学航空学院微型飞行器研究室研制的PY-1型扑翼机,建立了扑翼的运动模型,并采用非定常涡格法模拟了该扑翼的升力特性,分析了迎角、飞行速度对升力特性的影响。计算结果与实际飞行试验吻合,验证了非定常涡格法模拟扑翼非定常气动特性的正确性和有效性。研究结果可为扑翼机的气动设计提供参考。更多还原

【Abstract】 In this study,with background of NPU model of flapping wing, PY-1,a flapping model is established. Unsteady vortex-lattice method (UVLM) is used to analyse the lift characteristics of flapping wing. Comparison with the reference result show that UVLM is correct and efficient to simulate the flapping wing flight. In this paper, some parameters and their influence on lift of flapping wing are studied, such as attack angle, etc. The results are consistent with the actually flight test, and useful to the aerodynamic design of flapping wing.更多还原
