Honeywell (Stand B11, Hall 2) has received US and European certification for its TFE731-40 engine retrofit aboard the Falcon 50. Anheuser Busch is the first customer to commit to the Falcon 50-40 conversion.

The TFE731-40 powered Falcon 50 aircraft can climb to 41,000ft (12,400m) in approximately 16 minutes less than the -50's present climb performance of 39 minutes to 39,000ft. At altitude, the new engine can deliver as much as a 24% increase in cruise thrust over TFE731-3 engines and nearly a 10% reduction in TSFC.

Exchange

The retrofit programme will be on an exchange basis for TFE731-3 engines currently powering nearly 250 Falcon 50 aircraft in service worldwide.

Each TFE731-40 will give Falcon 50 operators flat-rated, hot-day performance of 3,700lb (16.4kN) of take-off thrust at sea level, improved fuel economy at altitude and extended engine inspection intervals. The engine is rated at 1,010lb of cruise thrust at 40,000ft at Mach 0.8.

Hourly Maintenance Service Plan rates for 2001 will also drop by nearly 40%. The 731-40 engine carries maintenance intervals of 2,500h for major periodic inspections and 5,000h for compressor zone inspections, a 16% improvement over existing engines.

Control

The engine includes a Digital Electronic Engine Control allowing automatic takeoff, climb and cruise thrust settings; newly designed ceramic seals; a new oil pump; enhanced turbine cooling; an improved combustor and improved compressor durability.

"The TFE731-40 engine will give Falcon 50 operators faster time-to-climb and cruise speeds, improved engine reliability, durability and reduced cost of ownership," says Dominique Hedon, vice -president, Commercial Propulsion, Honeywell Engines and Systems.
