Shape Optimization of Hypersonic Axisymmetric Body for Low Drag and Low Heat Load

摘要：

We have conducted shape optimization of hypersonic axisymmetric body with fineness ratio 1.5 for low drag and low heating rate by incorporating constrained optimization method (in this study, Sequential Quadratic Programming (SQP□algorithm was applied□ with Navier-Stokes flow solver. In this study, it is shown that the minimum drag is obtained not for a pointed nose body but for a blunted nose body, even when the stagnation convective heating rate is not constrained. By the present method, we successfully found the optimized shape which suffices the heating rate constraint with almost the same drag coefficient as the result with no heating rate constraint.
