Pratt & Whitney Canada’s PurePower PW814GA and PW815GA engines—which will power the Gulfstream G500 and G600, respectively—received type certification from Transport Canada earlier this week. During testing, the PW800 engines logged more than 3,300 hours, including more than 350 flight hours on P&WC's Boeing 747SP flying testbed. In addition, the PurePower PW800 engine's common core technology, leveraged in six PurePower engine applications, has amassed a total of 15,000 testing hours.
"The PurePower PW800 engine has successfully achieved all of its objectives under a broad range of environmental and operating conditions, exceeding expectations," said P&WC vice president of engineering Walter Di Bartolomeo. "We are thrilled with the engine's performance, fuel efficiency and environmental characteristics.” This includes a double-digit improvement in fuel burn over the previous generation of engines in this thrust class, as well as low levels of nitrous-oxide emissions and smoke.
P&WC is providing the entire integrated powerplant system—engine, nacelle and thrust reversers—for the G500 and G600. The Gulfstream G500 is slated to fly this year, followed by the G600 in 2017. Entry into service for the new twinjets is expected in 2018 and 2019, respectively.
