Large-Scale Computations for Stability Analysis of Launch Vehicles Using Cluster Computers

摘要

A procedure is developed to generate a large aerodynamic database suitable for the static stability analysis ofnlaunch vehicles in the transonic regime by using the Navier–Stokes equations. Effects of structural deformations arenalso included using modal representation. It is shown that a large number of cases suitable for design can bencomputed within practical time limitations by using efficient protocols suitable for massively parallel computationsnon superclusters. Results are validated with wind-tunnel measurements that show good comparisons within thenlimits of themodel size.Massive computations on superclusters reveal important observations, such as highermodesnhaving pronounced effects near transonic regime.
