The European Aviation Safety Agency (EASA) has granted full flight certification to the Rolls-Royce Trent 1000 TEN, destined to power all variants of the Boeing 787 Dreamliner, the engine company announced Friday. The milestone comes as the first set of production engines arrives at Boeing facilities in Seattle, ready for entry into service later this year.

The Trent 1000 TEN incorporates technologies from the Trent XWB and Advance engine programs to deliver improved thrust and efficiency and reduce noise footprint by some 50 percent compared with previous-generation widebodies. 

Earlier this year the Trent 1000 engine achieved its third “first” when it powered the first flight of the Boeing 787-10 Dreamliner on March 31. That engine also powered the first flights of the 787-8 and the 787-9. More recently the Trent 1000 TEN powered an 18-hour test flight during which a Boeing 787-8 Dreamliner test aircraft drew a giant outline of the airplane across the U.S.

Features developed for the Airbus A350’s more-powerful Trent XWB also found in the 76,000-pound-thrust TEN include a “rising-line” compressor and three-stage bladed disc (blisk) at the front of the high-pressure compressor.

Rolls-Royce says that on flights of up to 3,000 miles the TEN offers a specific fuel consumption advantage of some 3 percent, although that differential decays over longer sectors. For flights of average 787 range, the basic Trent 1000 delivers a fuel-burn advantage “well ahead” of the GEnx-1B at shorter ranges, according to Rolls.
