Internal convective heat transfer mechanism in reentry space vehicles
Abstract
Technical details of the development of an empirical formula describing the internal convective heat-transfer mechanism are discussed. Focus is placed on aerodynamic heating to the exterior thermal protection system (TPS) surfaces, thermal modeling of the TPS elements, and thermal modeling of the structure that accounts for the heat-sink effects of a heavier nearby structure on the skin panel temperature response. Inner mold line (IML) forced convection relationships are established, and applications of the approach to various types of thermal analyses required for the design and performance evaluation of future hypersonic reentry spacecraft such as National AeroSpace Plane (NASP), Assured Crew Return Vehicle (ACRV), and Shuttle-derived reentry vehicles are considered.
