Radial Slot Application Method for Strain Relief of Solid Rocket Motor

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. . , .
