Rolls-Royce is on track to achieve ETOPS certificate for its Trent 7000 engine in October, the manufacturer said at the Farnborough Air Show.
The engine, which is the sole engine offered on the Airbus A330neo, is scheduled to enter service with TAP Air Portugal later this year and in recent weeks has been involved in route-proving flights.
“We’ve been really, really pleased with the overall flight-test program since last October,” Trent 7000 program director Chris Davie said in a briefing prior to the show. Route-proving fights to South America had particularly pointed up the quietness of the A330neo’s cabin, he added.
Rolls-Royce said the Trent 7000 offers a 10% improvement in fuel burn over its Trent 700 predecessor, which powers the A330ceo. The new engine uses technology from the company’s Trent XWB, which powers the A350, and is markedly larger than the Trent 700: “It’s as big an engine as you can put under the A330’s wing,” Davie said.
One example of the Trent 7000 is undergoing ETOPS testing at the Stennis Space Center in Mississippi and is around halfway through its 3,000-cycle program. “There have been a couple of issues with the testbed systems, but it’s progressing well and we’re hoping to complete testing by early August,” Davie said.
“We then have to strip the engine down and assess all the components. We hope to do that by the end of September/early October and are aiming to have ETOPS certification by October.”
