초록

본 연구는 초음속 로켓 제트 후류 전산음향 해석에 소요되는 해석 시간을 줄이기 위해 수행되었다. 해석 시간을 줄이기 위한 방안으로 초음속 제트 후류를 2차원 축대칭 문제로 가정하고 전산음향 해석을 수행하였다. 전산음향 해석 결과, 음향하중 계측 결과와 유사한 결과를 보였다. 본 연구를 통해 2차원 축대칭 전산해석을 이용하여 초음속 로켓 제트 후류의 음향하중 예측이 가능함을 확인할 수 있었다.

This study was conducted to reduce the computation time required for the computational acoustic analysis of the supersonic rocket jet plume. In order to reduce the computation time, computational acoustic analysis was performed assuming that the supersonic jet plume is a two-dimensional axis-symmetric problem. The results of computational acoustic analysis showed similar results to the acoustic load measurement results. Through this study, it was confirmed that the acoustic load prediction of the supersonic rocket jet plume can be predicted using a two-dimensional axis-symmetric computational analysis.
