摘要

扑翼弹箭飞行器在现代化智能战争中因其独特的高升力与低噪声性能而备受关注,扑翼弹箭飞行器可解决传统微型无人飞行器在机翼大迎角时的失速与不稳定流动问题。针对此飞行器的优势,本文利用大涡模拟方法,通过动网格技术与FW-H方程,建立针对仿生双翅扑翼的气动/噪声混合数值模拟方法,对双翅扑翼的高升力机理与噪声强度展开研究。本文通过模拟扑翼流场涡结构,探究其扑动时高升力机理与大迎角稳定流动现象的产生原理,研究发现其展向涡对大迎角状态下的流动具有稳定作用,可维持高升力0.18倍周期时间,流场处于较为稳定的状态,距扑动中心10倍弦长处噪声强度最高可达85dB,具备较好的气动特性与噪声强度特性。

Abstract

The flapping-wing projectile aircraft has garnered significant attention in modern intelligent warfare due to its distinctive high-lift and low-noise performance.The flapping-wing projectile aircraft can address the stall and unstable flow issues of traditional micro unmanned aerial vehicles at large wing angles of attack.In light of the advantages of this aircraft,this paper employs the large eddy simulation method,through the dynamic mesh technology and the FW-H equation,to establish an aerodynamic/noise hybrid numerical simulation approach for bionic double-wing flapping,and conducts research on the high-lift mechanism and noise intensity of the double-wing flapping.By simulating the vortex structure of the flapping wing flow field,this paper explores the generation principles of the high-lift mechanism and stable flow phenomenon at large angles of attack during flapping.The study discovers that the spanwise vortex has a stabilizing effect on the flow at large angles of attack,capable of maintaining the high lift for 0.18 times the flapping period.The flow field is in a relatively stable state.The noise intensity at a distance of 10 times the chord length from the flapping center can reach up to 85dB,demonstrating favorable aerodynamic and noise intensity characteristics.
