우주발사체 비행에 의한 발사장 주변의 음향 소음에 대하여 분석하였다. 발사체 엔진배기 제트에 소음원을 위치시키고 소음의 방향성, 대기 감쇄 등을 고려하여 발사장 주변의 특정 지점에 미치는 소음의 크기를 예측하였다. KSLV-I의 발사 소음을 예측하고 이 결과를 비행시험시의 측정 결과와 비교하였다. 분석 결과는 소음의 방향성에 의해 큰 영향을 받는 것으로 나타났으며 소음 방향성 정보에 대한 적절한 가정에 의해 시험 결과와 예측결과가 서로 잘 일치하는 것을 확인하였다.
Abstract
The acoustic noise around a launch pad by launches of space launch vehicles was analyzed. The magnitudes of sound noise at some points near launch pad were predicted by locating the sound source at the exhaust jet plume of the rocket engine and considering several factors such as the directivity of the sound propagation and atmospheric attenuation. Specifically, the launch noise of Korea Space Launch Vehicle-I(KSLV-I) was estimated, and was compared to the actual measurement results. The analysis results proved to be heavily affected by the characteristics of directivity of sound propagation and the analysis showed good agreements with the measurements when the directivity of the sound was appropriately adjusted.
