摘要/Abstract

摘要：

以菱形翼布局高空长航时（HALE）传感器无人机研究为背景，分析了翼型内部安装平面相控阵雷达天线的基本原理。通过推导雷达探测性能的估算方程，建立了在翼型中安装平面相控阵雷达天线的数学模型。采用数值模拟的方法，对典型雷诺数下的RAE2822翼型的气动特性进行了研究并与试验数据进行了对比，验证了使用有限体积法k-ω SST （Shear Stress Transport）湍流模型求解雷诺平均Navier-Stokes方程在这一状态下的可靠性和适用性；同时对不同厚度的NACA 64A系列翼型的流场结构和流动机理进行了分析，在此基础上提出了一种满足平面相控阵雷达天线安装情况下翼型的优化设计思想。优化结果验证了这一设计思想的可行性。

Abstract:

To develop High-Altitude Long-Endurance (HALE) diamond-wing configuration SensorCraft, the installation of the planar phased array radar antenna inside the airfoil is studied. A mathematic model for the planar phased array radar antenna is established by solving the equation for radar performance estimation. To verify the reliability and applicability of the k-ω SST (Shear Stress Transport) turbulence model and the finite volume method used to solve the Reynolds-averaged Navier-Stokes equations, the aerodynamic characteristics of the supercritical airfoil RAE2822 with typical Reynolds number are studied by numerical simulation, and the results are compared with the experimental data. An analysis of the flow field structure and flow mechanism of NACA 64A series airfoil with different thickness is also carried out. On the basis of above studies, an optimization design method for the airfoil to meet the installation requirements of the planar phased array radar antenna is presented. The design results validate the feasibility of our optimization method.

Key words: phased arrays antenna, diamond-wing configuration, high-altitude long-endurance (HALE), flow field structure, flow mechanism, optimization design
