Abstract

The present invention relates to a standoff panel thermal protection system and a method of making the same. The system (1) includes a sandwich panel comprising: a first ceramic matrix composite facing sheet and a second ceramic matrix composite facing sheet. A ceramic matrix composite core is positioned between the first ceramic matrix composite facing sheet and the second ceramic matrix composite facing sheet. The ceramic matrix composite core has a perimeter. The first ceramic matrix composite facing sheet and the second ceramic matrix composite facing sheet extend beyond the perimeter to form an enclosure between the first ceramic matrix composite facing sheet and the second ceramic matrix composite facing sheet. The ceramic matrix composite core gap. Holes are formed through the sandwich panel. The heat protection system further includes: a soft commodity seal positioned in the gap; a plurality of spacer members; a plurality of standoff brackets; and a plurality of fasteners positionable through the plurality of holes to couple the sandwich panel to the plurality of supports.

Description

technical field [0001] The present disclosure relates to a standoff panel thermal protection system for a vehicle and a method of manufacturing the same. Background technique [0002] Reusable launch vehicles and hypersonic vehicles employ thermal protection systems to protect primary structures, fuel and internal components against the thermal loads experienced in flight. Various architectures of thermal protection systems have been used in the past, including ablative layers, integrated thermal structures, phase change materials, and various other parasitic systems, including parasitic standoff panel systems, bonded tiles, thermal blankets, and oxide CMC-wrapped tiles . [0003] The aforementioned parasitic standoff panel constructions have used superalloy metal honeycomb panels or non-oxide laminate panels as structural elements making up the exposed surfaces of the vehicle. The panels are usually attached to the stand-off brackets with metal fasteners installed such th...
