Abstract

In this paper, we studied the application of a radial slot to the propulsion engine to relieve the strain of solid propellant by applying the optimal design concept to the shape and location of the radial slot. The propulsion engine under study was set to be a high-ratio, high-charge propulsion engine that requires the application of radial slots due to its high overall strain. The optimization was performed in conjunction with ABAQUS’s 3D structural analysis based on codes written in MATLAB.

본 논문에서는 래디얼 슬롯의 형상과 위치에 최적설계 개념을 적용하여 고체 추진제의 변형률 완화를 위한 래디얼 슬롯의 추진기관 적용 방안에 관해 연구하였다. 연구 대상 추진기관은 전체적인 변형률이 높아 래디얼 슬롯 적용 필요성이 높은 고세장비, 고충전 추진기관으로 설정하였다. 최적설계는 MATLAB으로 작성된 코드를 기반으로 ABAQUS의 3차원 구조해석과 연동하여 수행되었다.
