Pratt & Whitney Canada engines that will power Gulfstream’s newest business jets have received type certification from Transport Canada.
The company said its PurePower PW814GA and PW815GA engines that will be used on the Gulfstream G500 and G600, respectively, came after more than 3,300 hours of evaluation, including about 350 flight hours of testing on its Boeing 747SP flying test bed aircraft.
“The PurePower PW800 engine has successfully achieved all of its objectives under a broad range of environmental and operating conditions, exceeding expectations,” Pratt & Whitney Canada vice president of engineering Walter Di Bartolomeo said in a statement on Tuesday.
“We are thrilled with the engine’s performance, fuel efficiency and environmental characteristics, which put it far ahead of anticipated standards on emissions and noise levels and ensure its best-in-class availability.”
The Gulfstream G500 and G600, both wide-cabin aircraft that can seat up to 19 people and cruise at speeds of Mach 0.9, were launched in October 2014.
First flight of the G500, which has a range of 5,000nm, was due to take place in 2015 and Gulfstream hoped to receive type certification from the US Federal Aviation Administration and European Aviation Safety Agency in 2017, with deliveries to start in 2018.
Meanwhile, the flight test program for the 6,200mn range G600 was expected to begin between 12 to 18 months after the G500, with entry into service slated for 2019.
Gulfstream was expected to have its G650 and G280 aircraft on display at the Avalon Airshow, which runs from February 24 to March 1.
