Integrated Hypersonic Aerothermoelastic Methodology for Trans Atmospheric Vehicle (TAV)/Thermal Protection System (TPS) Structural Design and Optimization. Thermal Protection System Optimization (TPSOPT)

摘要

This report was developed under a SBIR contract. The objective of this project was to develop a hypersonic aerothermoelastic methodology that optimizes the Thermal Protection System (TPS) for the Trans Atmospheric Vehicles (TAV) in the re-entry/maneuver flight phases. The outcome of this project is a Thermal Protection System Optimization (TPSOPT) software system that integrates multiple disciplines, including the hypersonic aerodynamics, aerothermodynamics, heat transfer, aeroelasticity, with an automatic optimization technique for the minimum weight design of the TPS while subjected to the temperature constraints. A proper orthogonal decomposition and response surface method (PODIRSM) has also been integrated into the TPSOPT system to accelerate the aerodynamic data generation process. There are three manuals generated for the TPSOPT, namely the TPSOPT Theoretical Manual, the TPSOPT Users Manual and the TPSOPT Applications Manual. The design capability of the TPSOPT system is demonstrated on two wing-body configurations including the X- 34 and Micro-X vehicles and is documented in the TPSOPT Applications Manual. In addition, a ZONAIR-Adaptive Modeling Environment (ZONAIR-AME) using the Adaptive Modeling Language (AML) was developed by TechnoSoft, Inc. ZONAIR-AME is expedient aerodynamic mesh generation tool that allows varying of parametric geometry for rapid assessment of aerodynamic design concept.
