Abstract

CAV is a concept for a maneuvering reentry vehicle that brings a payload through the atmosphere from (sub)orbital trajectory. CAV uses an aero shell to protect payload and avionics from reentry heating. While the aero shell is the primary shield, a keyCAV technical need is an insulation system for the interior of the aero shell, protecting control electronics and payload. Besides thermal protection, the insulation should isolate from shock, vibration, and acoustic loads. Ocellus proposes anexceptional new composite material that will meet or exceed requirements for the CAV application. This material, named BRIA, consists of a novel low-density ceramic fiber matrix filled with heat-resistant aluminum oxide foam. It is lightweight,mechanically strong, easily fashioned into shapes, an excellent thermal insulator, stable to 2600¿F, and should exhibit extraordinary energy dissipation characteristics. Our approach is to engineer BRIA to meet CAV needs for interior insulation. In apreliminary design, the BRIA insulation system is attached directly to the inner surface of the aero shell, providing more payload space and critical protection should the aero shell be damaged. Phase I work includes characterization of BRIA, modeldevelopment for BRIA trade study, and preliminary design for BRIA in CAV. Immediate benefits from this Phase I activity would be the identification of an insulation system for the CAV that would offer value-added benefits such as, designs allowinginsulation in contact with aero shell to provide more payload space and protection to payload should aero shell be damaged. Longer term benefits stem from further development of BRIA and its use in other aerospace applications and, ultimately, commercialproducts. Besides CAV, an initial aerospace market strategy is to develop BRIA as a Thermal Protection System (TPS) for Space Vehicles, such as Reusable Launch Vehicles, expendable launch and reentry vehicles, and the current Shuttle fleet. Theseapplications would be enabled by an insulation material that provides excellent high temperature insulation, and possesses sufficient thermal tolerance and mechanical strength to withstand multiple atmospheric reentry cycles. The development of this largemarket would allow manufacturing scale-up and manufacturing efficencies. The secondary market, commercial products, feeds off of the systems and experience developed in the military/space market. This market would initially focus on niche applicationssuch as flight data recorders and specialty high temperature furnaces.
