Abstract
EFFECTIVE PERFORMANCE OF REUSABLE HYPERSONIC VEHICLES WILL DEPEND ON THE DEVELOPMENT OF THERMAL PROTECTION SYSTEMS (TPS) FOR NOSE TIP, WING LEADING EDGE, AND FUSELAGE STRUCTURES CAPABLE OF OPERATION FOR EXTENDED PERIODS IN AN EXTREME AEROHEATING ENVIRONMENT. MINIMUM WEIGHT DESIGN MAY BE ACHIEVED VIA A COMBINATION OF ACTIVE/PASSIVE TPS APPROACHES. THIS WOULD INVOLVE THE DEVELOPMENT OF A HIGH TEMPERATURE STRUCTURAL MATERIAL SYSTEM WHICH DISPLAYS GOOD STRENGTH, STIFFNESS AND DAMAGE TOLERANCE AT ELEVATED TEMPERATURE. SUCH A MATERIAL COULD BE PROTECTED BY A THIN LIGHTWEIGHT BARRIER MATERIAL AND WOULD REQUIRE ONLY MINIMAL ACTIVE COOLING. FOSTER-MILLER, INC. IS PROPOSING A NOVEL HYBRID ACTIVE/PASSIVE COOLING CONCEPT BASED ON STRUCTURAL ADVANCED CARBON-CARBON (ACC). THE CONCEPT IS AN INTEGRATED APPROACH WHICH COMBINES STRUCTURAL AND COOLING ELEMENTS FOR MINIMUM WEIGHT. FOSTER-MILLER IS PROPOSING A LOW COST INNOVATIVE METHOD TO CONVERT 2-D CARBON/PHENOLIC PREPREG TO 3-D DURING AUTOCLAVE PROCESSING. THE RESULTING ACC WILL HAVE IMPROVED TRANSVERSE (THROUGH-THICKNESS) STRENGTH AND CONDUCTIVITY. THE PROCESS CAN HANDLE THINWALL STRUCTURES OF COMPLEX SHAPE. INTEGRAL ATTACHMENT OF STIFFENERS IS POSSIBLE ELIMINATING THE NEED FOR SEPARATE C/C FASTENERS. CANDIDATE STRANSVERSE REINFORCING MATERIALS INCLUDE: BORON, SIC, TUNGSTEN, AND EXTENDED CARBON/PHENOLIC RODS. IN PHASE I SAMPLE TRANSVERSE REINFORCED C/C SPECIMENS WILL BE MADE AND TESTED FOR THERMAL PROPERTIES.
