Rolls-Royce is aiming to keep the weight of the Airbus A330neo's engine as close as possible to that of the Trent 1000-TEN for the Boeing 787.

The powerplant manufacturer is not disclosing detailed information about the weight of the Trent 7000 which, like the Trent 1000, will feature a 112in fan – larger than the Trent 700 at 97.5in.

Rolls-Royce says, however, that its target weight will be "less than 1%" heavier than the Trent 1000-TEN which is being developed for all three 787 variants.

It says that the weights of both engines "are very similar". There will be changes involving the full-authority digital engine control, gearbox bleed system and front bearings.

The Trent 7000 is the seventh iteration of the Trent line of powerplants.

Airbus has selected Safran Group division Aircelle to supply nacelles for the Trent 7000 engines on the A330neo programme.

The airframer formally signed the co-operation pact during an event at the Farnborough air show.

Aircelle says it will capitalise on its experience with other Airbus programmes, particularly the A380, using technology centred on composite materials and acoustic management.
