 ADVANCED NACELLE SAVES FUEL
 CHULA VISTA, Calif., Oct. 22 /PRNewswire/ -- Rohr Inc. (NYSE: RHR) recently participated in an industry-government team led by GE Aircraft Engines in a successful series of test flights to evaluate a concept to improve aircraft performance by maintaining laminar flow on a nacelle. Nacelles are the complex aerodynamic structures surrounding an aircraft engine.
 The benefit of laminar flow comes in the form of reduced friction drag. And since nacelle friction drag today accounts for 4 percent to 5 percent of the total friction drag of the aircraft, any reduction in nacelle friction drag causes a corresponding reduction in fuel consumption and aircraft operating costs. Thus, it is desirable to maintain laminar flow over as much of the nacelle surface as possible.
 The team's Hybrid Laminar Flow Nacelle configuration effectively combined improved aerodynamic lines with a nacelle surface suction system to achieve laminar flow.
 Drawing on more than a decade of laminar flow control experience, Rohr designed and provided the inlet and fan cowl fairings as well as the suction system's piping and valves, all in accordance with General Electric specifications. Allied-Signal, Garrett and NASA also provided equipment and on-site test support.
 "Laminar flow technology can save the US airline industry on the order of $100 million a year in reduced fuel bills and will be a key initiative at Rohr for future nacelles," said Dr. Alek Mikolajczak, Rohr's vice president of technology and new business.
 The flight tests were conducted during July and August at GE Aircraft Engine's Mojave Flight Test Center, Mojave, Calif., on an Airbus A300 powered by GE CF6-50C2 engines. The lessons learned from the evaluation are providing the aerodynamic, mechanical and structural guidelines to develop a production Hybrid Laminar Flow Nacelle for commercial applications by mid-decade.
 Rohr designs, integrates, manufactures and supports engine nacelle systems and components for commercial, military and business aircraft. The company also manufactures solid rocket motor casings and nozzles for the Titan IV launch vehicle. Rohr, headquartered in Chula Vista, has facilities in the United States and Europe.
