The Rolls-Royce Trent 1000 TEN, which will power all variants of the Boeing 787 Dreamliner, has been granted full flight certification from the European Aviation Safety Agency (EASA). The first set of passenger engines are delivered to the Boeing facilities in Seattle, ready for entry into service later this year.

The Trent 1000 TEN (Thrust, Efficiency and New Technology) incorporates technologies from the Trent XWB and Advance engine programmes to deliver improved thrust and efficiency and reduced noise footprint.

The Trent 1000 TEN, which flew for the first time on the Dreamliner in December 2016, powered the first flight of the Boeing 787-10 in March this year.

The Trent 1000 is one of the two powerplant offerings on the Dreamliner, alongside the GEnx. Features of the TEN — an upgraded version of the original Trent 1000 — include a new compressor system scaled from the Trent XWB engine programme and a new turbine design to allow extra thrust. Unique to the TEN is a modulated air system which optimises the secondary air flow within the engine using a valve system with no moving parts.

The original Trent 1000 is in service on around 170 Boeing 787s. Rolls-Royce announced in August last year that it was replacing all Trent 1000 intermediate pressure turbine blades with a new design due to fatigue cracking issues first noted by All Nippon Airways.
