Pratt & Whitney
PW1500G Engine Completes First Flight Test Program
By Shane Nolan
September 15, 2011 – The Pratt & Whitney PurePower
PW1500G engine, the PW1524G engine for the Bombardier
CSeries aircraft, completed its first flight test
program logging 25 flights with 115 flight hours.
The PW1524G engine has been flight testing on Pratt & Whitney’s 747SP flying test bed at Pratt & Whitney Canada’s Mirabel Aerospace Centre, in Mirabel, Québec (Canada) since June 20.
Final production assembly and test will also occur at
the Mirabel facility for both the PW1524G and P&WC’s
advanced PW800 family of PurePower engines for the next
generation of large business jets.
“We are very pleased with this initial flight test program,” said Bob Saia, vice president, Next Generation Product Family. “Results confirmed our earlier sea level test findings validating the geared turbofan’s overall engine design.
engine operated flawlessly enabling us to conduct double the
number of flight hours we initially planned. Our expanded test
program enabled us to conduct additional flight testing, which
was planned for early 2012. This engine will return to our sea
level test facility in West Palm, Florida to continue testing.”
addition to more than 800 hours of full engine testing to date,
Pratt & Whitney has performed critical part level and engine
sub-system testing to validate designs for the PurePower engine
program, including hundreds of hours of core and rig testing,
design validation of the fan drive gear system, bird ingestion
and fan blade containment and compressor performance for the
advanced PW1000G core. Pratt & Whitney currently has five
PW1000G family engines in test and an additional five in the
PW1500G engine test program will run a total of eight test
engines over the next 16 months with engine certification
scheduled for 2012 and entry into service in late 2013.
PurePower PW1000G series engines use an advanced gear system
allowing the engine’s fan to operate at a different speed than
the low-pressure compressor and turbine. The combination of the
gear system and an all-new advanced core deliver double-digit
improvements in fuel efficiency, environmental emissions and
PurePower family of engines shares common, advanced cores across
the PW1000G and PW800 models, and features flight proven,
next-generation technology. The engine core consists of an
ultra-efficient high-pressure compressor, a low-emissions
combustor, and state-of- the-art high-pressure turbine module.
The PW1500G engine
test program also supports the development of Pratt & Whitney Canada’s
PurePower PW800 engine for the next generation of large business jets.
The PW800 engine is a 10,000- to 20,000-pound thrust turbofan that has
double-digit improvements in fuel burn, environmental emissions, engine
noise and operating costs.
