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。
The long flight, the UAV is a new type of UAV, in the battlefield reconnaissance and atmospheric exploration has its special purpose. According to the characteristics of UAV, a normal two-tail pneumatic layout is adopted. Through the overall modeling, meshing, numerical calculation and application of Matlab software programming simulation, the characteristics of UAV lift resistance, longitudinal static stability and transverse navigation Static stability, the calculated results meet the design requirements, which can provide the theoretical basis and technical support for the overall design of the long voyage UAV.
