Normal Force Computation for Axisymmetric Multistage Launch Vehicle

Abstract:

The increased demand upon the aeroelastician to obtain the distributed aerodynamic normal force loads for arbitrary launch vehicle configurations necessitated accurate method. In this work, computational fluid dynamics (CFD) is used for the determining the distributed aerodynamic loads of an axisymmetric multistage launch vehicle in the linear angle-of-attack range. ICEM-CFD and ANSYS-FLUENT software are implemented for the meshing and computational analysis. About 2750 iterations were used for the simulation purpose. Computational results are compared to available experimental data. In general, a good result within engineering error margins is obtained.
