| dc.description.abstract | So far, chemical rocket propulsion is the only practical means to reach space. Among this rocket propulsion category, Solid Rocket Motor (SRM) placed itself well as the simplest and cheapest propulsion system compared to liquid and hybrid propulsion systems. The design of modern SRMs is a complicated and highly interactive process that involves significant trade-offs between competing objectives such as performance, cost, safety, size, weight, etc. One of these designs is the dualthrust single-chamber SRM (DT-SRM) that is used in several new rocket vehicles. In the literature, the design of DT-SRM has only been treated from the propellant grain perspective ignoring the inherent interaction with other motor design parameters.Moreover, most of these design models were numerical which increased the computational burden. Such approach is limited when implemented on a real-world problem, where all design parameters are affecting each other, and subsequently need to be optimized from a system point of view to give a more efficient and reliable design. Consequently, the ultimate goal of this thesis is to propose, validate, and implement a cost-effective and integrated system design optimisationframework to the preliminary design of DT-SRM based on the main motor design disciplines namely, casing, propellant grain, nozzle, and mass. To satisfy the condition of the dual thrust, an analytical mathematical model for the complex 3-D finocyl propellant grain shape is built and integrated to the other motor design models to form a system design model. The particle swarm optimisation (PSO) algorithm was utilized, with slight modification, in a multidisciplinary design optimisation (MDO) framework to search for the optimum design variables that minimize the total mass of the motor under specified performance and geometrical constraints. The validation results against existing test-firing data confirmed the reliability of the proposed system designoptimisation approach. The proposed approach was successfully implemented in thepreliminary design of a DT-SRM test case, where the performance simulation results of the optimized system showed an improved DT-SRM system design. As a complementary study, the design optimisation results were supported by a flight performance analysis using a six-degrees of freedom (6-DOF) simulation, in which the optimized DT-SRM was capable to deliver a certain payload to a certain distance in a stable flight path. The proposed approach represents an affordable and reliable tool to the preliminary design and optimisation of DT-SRMs intended to serve as a propulsion system for medium-size aerospace vehicles. | |
