Honeywell’s HTF7500E engine, selected to power Embraer’s new Legacy 450 and Legacy 500 series aircraft has passed its First Engine To Test (FETT) milestone.
“The engine has delivered full-rated thrust in static and flight testing,” said Ron Rich, Vice President, Propulsion, Honeywell Aerospace. In the first phase of testing, the HTF7500E has completed nearly 60 hours of testing, including 79 starts and has over 20 hours of flight test time on our Boeing 757 test bed.”
HTF7500E has a 34.2-inch fan and a bypass ratio of 4.2. The engine is configured with four axial compressor stages, a single centrifugal compressor, an effusion-cooled combustor, a two-stage high-pressure turbine and a three-stage low-pressure turbine driving a high-efficiency fan. The engine will be offered with an on-condition maintenance program from the first day in service.
Honeywell will provide the HTF7500E to Embraer as an integrated powerplant system (IPPS) including nacelle, thrust reverser and all engine mounted accessories. Other Honeywell components and systems on the Legacy 450 and Legacy 500 series aircraft include the 36-150 Auxiliary Power Unit, Environmental Control System and electronic fuel controls.
The HTF7500E engine is expected to certify in 2011.
