Less is certainly more for P&WC’s PurePower® PW800 engine

When P&WC’s intrepid engineers set about designing the company’s latest turbofan engine – the PurePower® PW800 – they were inspired by a vision of an engine that could do more while requiring so much less. With the PW800 now in flight on Gulfstream’s G500 (and soon on the G600) business jet, inspiration has become reality with an engine that’s totally redefining what’s possible in a large business jet.

“The list of ‘less’ is impressive: less fuel consumption, less noise levels, less emissions, less weight and engine vibrations, 40 per cent less scheduled maintenance and 20 per cent fewer maintenance inspections,” says Scott McElvaine, Senior Director, PW800 Marketing & Customer Service. “And on the ‘more’ side of the equation, the engine provides the best overall performance, efficiency and quiet operation for high-speed, long- and ultra-long-range business jets, and the best power-to-weight ratio in its class.”

In the past twenty years, P&WC has certified more than 100 engines. Scott, who’s been involved in the engine program for more than a decade, maintains that the PW800 is the embodiment of all that the company has learned from all the engine programs that have gone before it.

The engine’s maintenance footprint is unlike anything else currently in the segment, he says. “Open a cowling door for example, and a ladder appears to give the technician direct access to the engine above,” says Scott.  “There are special access ports built into the engine that also allow for efficient and rapid on-wing maintenance.

Scott also points to the engine’s environmental footprint as an example of how its performance exceeds today’s standards and reaches to meet the standards of tomorrow.

“We can offer our operators peace of mind knowing the PW800 engine will meet environmental regulations over the long term,” says Scott. “The engine clears the ICAO community noise requirements by a double-digit margin, making it easily the quietest engine in its class. And it does this all the while delivering benchmark fuel efficiency with an improvement of more than 10 per cent compared to similar engines in the same thrust class.”

The PW800 also has a track record of evaluation and testing that no competing engine can match. It has had more than 9,000 hours of evaluation tests and has completed in excess of 12,000 cycles. This includes more than 510 flights and over 4,000 engine flight test hours combined on P&WC’s flying test bed and Gulfstream’s G500 flight test aircraft.

“The PW800 engine will have 99.99 per cent dispatch reliability,” says Scott, “once again ensuring operators they will be able to do more while having a lot less to worry about.”
