Abstract:
1. A combined thermal protection and surface temperature control apparatus comprising: a porous member comprising an entrance side, a separate exit side, and pores substantially in the size range of 5 to 50 microns; one or more coolant entrance channels extending through said entrance side, extending part-way through said porous member, and ending within said porous member before reaching said exit side; and one or more coolant exit channels beginning within said porous member, extending through a portion of said porous member, and extending through said exit side; wherein the porous member has a thermal conductivity at least as low as 0.046 BTU/hr-ft-° R at room temperature and is configured so that when coolant flows into the one or more coolant entrance channels, coolant will flow from the one or more coolant entrance channels, through the pores of the porous member which are disposed between the one or more coolant entrance channels and the one or more coolant exit channels, into the one or more coolant exit channels, and out of the one or more coolant entrance channels while substantially restricting the flow of coolant through other areas of the porous member.
