Rolls-Royce announced today (17 May) that the Trent 900, which will be the first engine into commercial service on the Airbus A380, had successfully completed its first flight.
The Airbus A340-300 flying test bed on which the Trent 900 was installed was airborne for 3 hours and 20 minutes during which it reached an altitude of 35,000 ft and speeds up to MACH .86.
Airbus Test Pilot Peter Chandler said the engine had more than met expectations on this, its first flight test. He added: "The flight really is a great success. The engine performed very well during the flight and we have been able to complete the preparation for our follow-on flights."
The aircraft will now undertake a programme of approximately 50 flying hours through to August, enabling the engine, nacelle and aircraft interfaces to be fully evaluated before the start of flight testing of the 555-seat A380 in early 2005.
Ian Crawford, Director Airbus Programmes, Rolls-Royce, said: "We're delighted to see the Trent 900 successfully complete its first flight. We've been pleased with the results from the testing already completed and these have given us confidence for the rest of the programme.
"There's no doubt that our low-risk approach of blending new technology with Trent in-service experience means a high level of predictability in development - but it's still a great moment to see the engine take to the air."
Environmental testing has shown the Trent 900 to be the world's cleanest large turbofan engine measured by emissions per pound of thrust. Its significantly lower noise levels also mean it is on target to be the quietest engine on the A380. Future programme milestones include engine certification in October this year and while the engine will only require a rating of 70,000lb thrust at entry into service, it will be cleared for 81,000lb at certification. It has already run successfully at 88,000lb thrust in test.

The GE90-115B has more thrust (115300 with room to grow)
Maximum Diameter (Inches) 135
Length (Inches) 287
High-Pressure Turbine Stages 6/2
In comparison, the Trent 900 has a thrust of 68000-80000
Fan diameter: 116 inches
8.0 – 8.1 high bypass ratio
Eight-stage IP compressor
Six-stage HP compressor
Tiled combustor with 20 fuel injectors
Single-stage HP and IP turbine
Five-stage LP turbine
So the Trent is smaller.

I wonder if with all that thrust from the new engine, did they keep engine 1 throttled back a bit during takeoff (and throughout the flight) to maintain centerline thrust? Or do you think they didn't put the new engine at takeoff power?

Wow, that RR Trent 900 engine dwarfs all the other small CFM engines on the A340 . . . reminds me of the time back in Jan 2003 when N747GE had the GE90-115B as the #2 engine, it made the other PW engines look tiny.

I'm not really surprised. For a double Decker, that is just the right size but for a single deck with a length almost the size of a A330.. The engines are way too large for the 777. DoThey provide the 777 with more speed or because the engine was made large to be efficient ?
4 decks 4 engines 4 long haul
25 RayChuang: The reason why the Rolls-Royce Trent 970 and the Engine Alliance GP7270 engines have such big front fans is because Airbus wants the front fan rotatio
26 Mdsh00: The engines are way too large for the 777. Pardon me but I thought the GE's on the 777 are still larger...
