Inertial Upper Stage Three-Dimensional Thermal Analysis

Abstract

An efficient technique for three-dimensional thermal modeling which involves automated preprocessing, analysis, and post-processing is discussed. The technique is based on a finite element method and computer-aided-design geometry modeling. The results obtained from thermal analysis are directly compatible with structural computational mesh without any interpolation. Numerical calculations are carried out for a three-dimensional convection heating fixture configuration from The Aerospace Corporation's Aerophysics Laboratory arc jet test and for an IUS SRM-2 full-scale titanium housing subject to an oxygen-acetylene torch heating performed at United Technologies Corporation's Chemical Systems Division. The computed temperature data are compared with those of thermocouple measurements. They are presented in three- dimensional colored temperature contours with enhanced temperature field visualization which provides designers with clear pictures of thermal penetration in three-dimensional objects.
