Abstract:

The combined radiation and conduction heat transfer in multilayer insulation (MLI) of reusable lunch vehicle was investigated by the finite element method to simulate reentry aerodynamic heating conditions. The temperature field in MLI was presented. The effects of the design parameters such as foil arrangement, foil spacing and the distance form the top foil to the heat boundary were analyzed to give an instruction for MLI optimum design.
