PRATT & WHITNEY'S PW4000 PERFORMANCE IMPROVEMENT PACKAGE RECEIVES FAA CERTIFICATION

 EAST HARTFORD, Conn., June 17 /PRNewswire/ -- Pratt & Whitney's (P&W) enhanced PW4000 turbofan, to improve thrust specific fuel consumption in the 50,000 -- to 62,000 -- pound thrust class engines, has been certified for service by the Federal Aviation Administration (FAA). Rigorous sea level and altitude testing proved the modified engine configuration to have durability and operability well in excess of airline requirements.
 Testing at simulated altitude conditions in the P&W Andrew Wilgoos laboratory, confirmed a 3.1 percent improvement in thrust specific fuel consumption (TSFC) of the PW4000 propulsion system.
 This engine configuration, referred to as Phase III, includes an improved, state of the art fan blade, improved materials, coating and cooling of the high pressure turbine airfoils, reduced leakage fan case, improved low turbine aerodynamics, and enhanced full-authority digital electronic control (FADEC) capabilities for turbine case cooling optimization. For engines being installed on Airbus or McDonnell Douglas aircraft, where Pratt & Whitney provides the entire propulsion system, an improved nacelle with enhanced nozzle performance and thrust reverser sealing improvements have been added.
 A three percent reduction in TSFC can mean substantial savings to an operator. For example, an MD-11 operator could save up to $300,000 per aircraft per year in fuel costs based on flying a typical mission.
 Current plans call for the Phase III PW4000 engine to begin MD-11 flight testing in July with aircraft certification scheduled for later this year. Phase III engine certification for Airbus and Boeing airplanes will follow in early 1994. The Phase III package will be available for retrofit for in-service PW4000 engines.
 Pratt & Whitney is a unit of United Technologies Corporation (NYSE: UTX), based in Hartford, Conn.
