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.
