차세대 수직이착륙기의 주요 구성 요소별 레이더 포착 면적 분석

초록

Coaxial rotorcraft and tiltrotor aircraft are attracting attention as the next-generation VTOL aircraft. In this study, the radar cross section (RCS) of the UH-60A, SB>1 Defiant, and V-280 Valor models were compared to analyze the survivability related to radar signals of VTOL aircraft. The RCS analysis was conducted using the PO(Physical Optics) method in the X-band region of 10 GHz. In order to identify the main RCS sources of the next-generation VTOL aircraft, the RCS of the SB>1 Defiant and V-280 Valor was analyzed by component. The results showed that the next-generation VTOL aircraft had an overall higher RCS than the existing VTOL aircraft. In particular, a small number of components were found to have a dominant effect on the overall RCS.
