Pratt
& Whitney Canada PW610F Turbofan
The
Pratt & Whitney Canada PW610F is a medium-bypass turbofan
that is flat-rated at 900-lbf takeoff thrust at sea level
up to 77°F.
The two-spool design of the PW610F features a single-stage
high pressure turbine driving a mixed-flow and centrifugal
high pressure compressor and a single-stage low pressure
turbine driving a 14-inch one-piece titanium integrated
bladed rotor fan. Engine control is provided by a Full Authority
Digital Engine Control (FADEC). Thrust is managed through
power lever input signal to the FADEC, which controls a
fuel metering unit. The FADEC utilizes air data, engine
spool speeds, and EGT from sensor inputs to adjust fuel
schedules and govern engine operation within limits. Additional
FADEC features include auto-start, in-flight auto-restart,
overtemperature and overspeed protection to enhance safety
and performance while reducing pilot workload.
The PW610F engine features a 3-year, 1000-hour comprehensive warranty package. It includes an initial Time Between Overhaul (TBO) period of 3,500 hours and a mid-life Hot Section Inspection (HSI) term of 1,750 hours.
The
PW600 series of engines started with the PW625, a 2500-lbf
thrust demonstrator engine that has undergone testing in
test cells as well as on a flying test bed, fulfilling all
of its stated objectives.
