“…Based on the previous methodologies, many researchers in academies or rocket companies in the United States and several European countries have developed sophisticated internal ballistics codes to deal with fluid-structure interactions with moving grain boundary [13][14][15][16][17][18]. A substantial use of the level set and its related methods has been observed in these sophisticated internal ballistics codes.…”

Practical surface-tracking methods are successfully developed to simulate the evolution of the grain geometry, which is dynamically regressing during the combustion of the solid propellant. Three methods, namely the fronttracking, emanating-ray, and least-distance methods, are proposed. The front-tracking method is based on the Lagrangian approach, whereas both the emanating-ray and the least-distance methods are formulated from the Eulerian viewpoint. Three two-dimensional test cases have been examined to compare the programming complexity, simulation accuracy, and computational efficiency of the proposed methods. It is found that the least-distance method performs superior to the other two methods in many numerical respects. The least-distance method is implemented on the tetrahedron grid system to track the outwardly regressing surface of a three-dimensional cubical propellant. Comparison between the predicted erosive volume and burning surface area with the theoretical results yields satisfactory agreement. A grain design similar to one of the Falcon Launch V cases has been employed to demonstrate the usefulness of the proposed methodology in application to a practical three-dimensional grain burnback analysis.

“…Hu et al (1994) presented a design study on high thrust ratio approach using single chamber dual-thrust solid rocket motor. Dunn and Coats (1997) described dual-thrust approach using dual propellant. The above cited literature does not provide variety for dual-thrust motor design and optimisation approach, providing an exigent motive to address this issue.…”

2012) Uncertainty-based computational robust design optimisation of dual-thrust propulsion system, Journal of Engineering Design, 23:8, 618-634, This paper proposes a robust design optimisation methodology for performance evaluation of high-fidelity propulsion systems under both aleatory and epistemic uncertainties. In this paper, uncertainty-based robust design methodology is applied using first-order orthogonal design to estimate worst case of the uncertainties. The effectiveness and computational efficiency of proposed formulation is obtained by decoupling computation of both types of uncertainties in the optimisation process loop. The system robustness is measured by directly minimising the variance of target mean and standard deviation and adhering to performance constraints. A parametric sensitivity analysis of performance parameters due to input parameters variations is also performed to identify the most significant design variables. A hybrid genetic algorithm and simulated annealing approach are used as an optimiser. By using the proposed method, the objective function to maximise the booster phase to sustain phase thrust ratio and total impulse could be achieved while adhering to the motor performance constraints to provide an insensitive solution.

The research work proposed herein addresses and emphasizes a design methodology to design and optimize Finocyl Grain configurations considering particular test case for which the Average thrust and constraints have been given. A parametric solid model of the grain has been developed which enables automatic volume calculation of the grain void and solid propellant at each web increment thereafter burning area has been calculated. The motor performance is calculated using a simplified ballistic model, steady state pressure is calculated by equating mass generated in chamber to mass ejected through nozzle throat. Genetic algorithm has been employed for conducting optimization thereby achieving the design and performance objectives while adhering to design constraints. Latin hypercube sampling is used for better design space exploration and thus creating initial population to decrease computation time. Sensitivity Analysis of the optimized solution has been conducted using Monte Carlo method to evaluate the effects of uncertainties in design parameters caused by manufacturing variations.
