Analysis on Aerodynamic Performance and Stability of one Certain UAV

摘要:

长航时,无人机是一种新型的无人飞行器,在战场侦察和大气探测等方面有其特殊的用途。根据无人机特点,采用了正常式双尾撑气动布局,通过总体建模、网格划分、数值计算并应用 Matlab软件编程仿真,分析了无人机升阻特性、纵向静稳定性和横航行静稳定性,计算结果达到设计要求,可为长航时无人机总体设计提供理论依据和技术支持。

Abstract:

The long-endurance UAV is a new unmanned aerial vehicle. In battlefield reconnaissance and high-altitude at.mospheric sounding and so on has its special uses. According to the characteristics of UAV, double tail brace conventionalconfiguration was constructed. Through modeling, meshing, numerical calculation and matlab software simulation, vortexlattice method was applied to analyze the UAV lift-drag characteristics, longitudinal static stability, lateral and directionalstatic stability. The calculation results fulfilled design objectives and which could provide theoretical basis for long-endur.ance UAV conceptual and preliminary design.
