Abstract

A hybrid iterative physical optics-method of moments(IPO-MoM) technique is presented for the analysis of jet engine structures which are both electrically large and complex. In this technique, the IPO method is used to analyze smooth inlet region and the MoM method is used to analyze electrically complex region inclusive of blades and hub. It is efficient and accurate by virtue of combining the respective merits of both methods. Numerical results are presented and validated through comparison with Mode-FDTD and measured results.

전기적으로 크면서 동시에 복잡한 구조인 제트 엔진의 산란 해석을 위해 하이브리드 IPO-MoM(Iterative Physical Optics-Method of Moments) 기법을 제시하였다. 이 기법에서 IPO 기법은 전기적으로 부드럽게 변하는 inlet 영역을, MoM 기법은 회전축과 회전날개를 포함한 전기적으로 복잡하게 변하는 영역을 해석하였다. 각 기법의 장점을 융합하여 상대적으로 효율적이고 정확한 해석이 가능하였다. 수치 결과를 제시하고 기존 Mode-FDTD, 측정 결과와 비교하여 제시한 기법을 검증하였다.
