ARC - First Titanium Matrix Composite Aircraft Part Passes Critical Design Review for Flight.GAINESVILLE, Va.--(BUSINESS WIRE)--July 8, 1996--Atlantic Research Corp. (ARC) announces that the first titanium matrix composite aircraft part has successfully passed the critical design review for flight. The Air Force F-22 System Program Office, Pratt & Whitney, Parker Bertea, and Atlantic Research Corp. recently reviewed performance test results, processing information and quality assurance data for a new titanium matrix composite piston for a turbine engine actuator A mechanism that causes a device to be turned on or off, adjusted or moved. The motor and mechanism that moves the head assembly on a disk drive or an arm of a robot is called an actuator. See access arm. . The actuator, which is manufactured by Parker Bertea of Irvine, Calif., is the divergent nozzle actuator for the Pratt & Whitney F119 turbine engine which is being developed in West Palm Beach, Fla. The F119 engine is the power plant for the twin engine F-22 fighter. The titanium matrix composite piston rod blank is manufactured by Atlantic Research Corp. Atlantic Research Corp. uses advanced techniques for co-winding titanium wire with silicon carbide silicon carbide, chemical compound, SiC, that forms extremely hard, dark, iridescent crystals that are insoluble in water and other common solvents. Widely used as an abrasive, it is marketed under such familiar trade names as Carborundum and Crystolon. monofilament monofilament, n a single strand of untwisted synthetic material such as nylon; used to create surgical sutures. monofilament to produce the composite material composite material or composite, any material made from at least two discrete substances, such as concrete. Many materials are produced as composites, such as the fiberglass-reinforced plastics used for automobile bodies and boat hulls, but the that has the same stiffness as a stainless steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. piston rod, but weighs 40% less than steel. This is the first titanium matrix composite part that has been included in the bill of materials The list of components that make up a system. For example, a bill of materials for a house would include the cement block, lumber, shingles, doors, windows, plumbing, electric, heating and so on. for initial flight release testing in a full scale development program. When the F-22 successfully completes the flight test program, the titanium matrix composite piston rod will be incorporated into the production bill of material. ARC, a unit of Sequa Corp., is a leading developer and producer of solid propellant solid propellant n. A rocket propellant in solid form, combining both fuel and oxidizer in the form of a compact, cohesive grain. rocket motors, gas generators, liquid propulsion systems, and advanced composite materials. As an example of defense conversion, ARC also produces solid propellant and other components for automotive airbags. ARC is a partner with AlliedSignal in joint ventures to supply the automotive market with inflator systems. Sequa Corp. is a diversified industrial company whose other principal interests include the manufacture and repair of jet engine components, as well as the production of specialty chemicals, can machinery, and automotive products.
