Abstract

To study the electromagnetic scattering characteristics of a morphing aircraft with Z-folding wings, a method of hybrid grid matrix transformation (HGMT) is presented. The radar cross-section (RCS) of the aircraft in the four Z-folding modes is calculated and analyzed. When considering the deflection of the outer wing separately, the RCS of the wing under the head and side azimuth shows obvious dynamic characteristics, while the peak and fluctuation range are quite different. When the mid wing and the outer wing are deflected upwards together, the RCS of the aircraft under the positive side direction could be significantly reduced. When the mid wing deflects upward and the outer wing remains level, the peak of the side RCS of the aircraft is slightly reduced. When the mid wing deflects upwards and the outer wing deflects downwards, this peak indicator is further reduced, while the local fluctuation of the side RCS of the aircraft is increased. The HGMT method is effective to study the electromagnetic scattering characteristics of the Z-folding aircraft.

摘要

为研究具有Z形折叠机翼的变体飞机的电磁散射特性，提出了一种混合网格矩阵变换（HGMT）方法。计算并分析了飞机在四种Z形折叠模式下的雷达散射截面（RCS）。单独考虑外翼偏折时，机翼在头部和侧面方位下的RCS呈现出明显的动态特性，但其峰值和波动范围差异较大。当中翼和外翼一起向上偏折时，飞机在正侧方向下的RCS可显著降低。当中翼向上偏折而外翼保持水平时，飞机侧面RCS的峰值略有降低。当中翼向上偏折而外翼向下偏折时，该峰值指标进一步降低，而飞机侧面RCS的局部波动增大。HGMT方法对于研究Z形折叠飞机的电磁散射特性是有效的。
