Description
Summary:To study the electromagnetic scattering characteristics of a W-type flying wing with two rotors, a computing method is presented. The method includes two modules: dynamic grid transformation and instantaneous RCS (radar cross-section) computing. The results show that the surface of the blade and the leading edge of the wing have a high level of scattering under the irradiation of forward radar waves. The scattering characteristics of the rotor support cabin are enhanced when electromagnetic waves are incident from the side. At the given positive elevation angle, the mean of aircraft RCS curve under side direction decreases first and then increases with the increase in azimuth. The fluctuation range of the aircraft RCS curve under different tail azimuths is similar at the given negative elevation angle. The computing method is effective for analyzing the RCS of the W-type flying wing.
