Unlike 2D grain configurations, 3D configurations are complex, hence, simulating their burnback inside the rocket combustion chamber is a tedious and time-consuming process. This study proposes a fast and simple approach for modeling, and evaluating the burning area of 3D propellant grains, based on particular features available in a commercial CAD software. A common 3D Finocyl grain configuration available in the literature has been taken as a test case. The results obtained from the proposed approach were compared with the published experimental data and showed good agreement. The proposed approach can handle any arbitrary complex grain geometry and provide fast and reliable analysis for the preliminary design stage of solid propellant rocket motors.

Many designers and manufacturers from different organizations prefer the SRM option when compared to other types of rocket propulsion systems. Although SRMs are relatively simple in principle, their modern types are complex systems that must incorporate several technical disciplines and teams to meet stringent mission requirements and design criteria. To accomplish their objective within given overall system requirements and constraints, SRM subsystems and components must be carefully designed and optimized. In this survey, the authors have attempted to highlight the most used algorithms, the most common design objectives, the recent trends, and the main challenges in SRM design optimization in a simplified and organized manner. The current effort was intended to serve as an initial guide for SRM designers and researchers in selecting the optimization method that well suits their problem, and to help them know where to go next.
