Optimization of the heat shield based on the sequential quadratic programming algorithm
With the development of the aerospace technology, precise design is in dire need in this field.Optimization of aerospace structure is the key work in the process of the structure design.The structure, especially those weight as the payload is the main object of the optimization.In order to get the best result that meet the general demand, the optimization must be executed under several constraints and calculate iteratively.In order to utilize the launch capability of the rocket, an engine heat shield is optimized in this paper.The optimization is excuted using the sequential quadratic programming(SQP) algorithm with the weight as the object, the first order frequency as the contraint and the dimensions of the truss structure section as the variables.The result shows that this optimization method produces a perfect outcome which provides basis for the fine design of the heat shield.
