Based on the conformal inlet of flying wing unmanned aerial vehicle(UAV)and the relevant engineering application,grilles with different grille hole spacing were designed.Research on the integrated design of aerodynamic and stealthy performance was carried out based on multilevel fast multipole method(MLFMM)and the numerical simulation with hybrid grid.Results indicated:(1)With the decrease of grille hole spacing,the electromagnetic shielding effectiveness increased gradually;at the frequency of 1GHz,the ele...
