Improved Composite Flexible Blanket Insulation

Improved composite flexible blanket insulation is quilt of layers of advanced lightweight insulating materials. Each layer designed to optimize contribution to inhibition of radiative, conductive, and/or convective transfer of heat from hot side to cold side. Intended to protect spacecraft against heating during reentry into atmosphere, used on Earth where requirements for lightweight, flexible, highly efficient insulating materials protect people and equipment against temperatures up to about 1,650 degrees C. Such as, furnace curtains and insulating layers on firefighting equipment and protective clothing.

Thermal response of rigid and flexible insulations and reflective coating in an aeroconvective heating environment

Described here is the thermal performance of rigid and flexible thermal protection systems considered for potential use in future Aeroassist Space Transfer Vehicles. The thermal response of these materials subjected to aeroconvective heating from a plasma arc is described. Properties that were measured included the thermal conductivity of both rigid and flexible insulations at various temperatures and pressures and the emissivity of the fabrics used in the flexible insulations. The results from computerized thermal analysis models describing the thermal response of these materials subjected to flight conditions are included.
