Abstract
Metallic thermal protection system (MTPS) is a key component in space vehicle design. By introducing thermal contact resistance (TCR) on the interface between different layers of MTPS, an one dimensional (1D) thermal conduction model for MTPS with multiple functions is established for thermal design. An optimization method is proposed to determine the thermal parameter by comparing the results of 1D finite differential simulation with the test ones. The thermal mode is analyzed by three dimensional FEM analysis and the results show that the mechanical characteristics of MTPS appear to be asymmetric which provides a new consideration to insulate the fluctuating load.
