A350-1000´s engine starts running on the Rolls-Royce test beds in Derby, UK.

Following closely after the first engine run of the Trent XWB-97 in July, the engine has achieved full takeoff power of 97,000 lbs.

Alistair McIntosh, Chief Engineer for the Trent XWB-97, said: “Reaching 97,000 lbs of thrust is another important milestone for us.  Like the saying goes ‘you need to learn to walk before you can run’, so we’ve been building up thrust levels over the last couple of weeks to understand how the engine performs against our models, before hitting full thrust.”  The engine will continue to test over the coming weeks to further explore the function and operability of the Trent XWB-97 design, across various thrusts and maneuvers.

“What impresses me most is the amount of running we’ve been able to do so far with this engine and how quickly we’ve done it.  It really shows how far we’ve come with our design techniques and tools,” added Alistair.  “We’re also coming from a solid baseline of having so much experience of the -84 engine.  What we need to do now is to execute the program we’ve set out, continue running this engine, and getting more -97 engines on to the test beds.”

Qatar Airways shows off 1st painted A350-900 MSN6

Qatar Airways’ first Airbus A350-900 has broken cover with its full livery.

The Doha-based airline is the launch customer of the A350 and it is planned that the first aircraft will be delivered by the end of the year.

This 1st aircraft, the MSN6, has been painted in the carrier’s distinctive grey-and-maroon livery.

In the pictures shown by Qatar Airways, the Rolls-Royce Trent XWB-84 engines are not installed.

As these pictures are from last week, the powerplants have already been installed in the FAL in Toulouse, as shown in these 2  pictures:

Test flights ongoing to demonstrate that the A350 can safely fly 7 hours using a single engine.

Airbus intends to ramp up flight tests this week to demonstrate that the A350 eventually should be allowed to fly routes taking it as many as 7 hours from an emergency landing strip. Trans-Atlantic flights to Goose Bay in Canada, Azores and Cape Verde are planned as these are common diversion airports.

The A350 would have unprecedented regulatory leeway compared with other twin-engine jets on ultra-long polar or over-water routes.

If European regulators grant approval in coming years, the wide-body jets would be able to take more direct routes to slash flight times, save fuel and give Airbus a potential marketing advantage connecting a limited number of destinations. Later, the FAA will be asked to give its stamp of approval. When the A350 goes into service in coming months, Airbus expects to have approval for diversions of more than 3 hours. (Between ETOPS 180 and ETOPS 330)

Industry officials said Airbus would win bragging rights for the A350 to fly virtually any nonstop route in the world without having to make adjustments to stay closer to potential diversion airports; Australia-Brazil and SouthAfrica-Australia are some of new nonstop routes that would be open for twin-engine jets.

More broadly, the issue also highlights the reliability of the latest generation of Rolls-Royce engines, along with electrical, fuel and fire-suppression systems.

“This is the first time we are targeting such an aggressive ETOPS certification,” said Fernando Alonso, SVP for flight testing at Airbus. To combat fire, one batch of extinguishers is designed to put out the flames. A second group would release chemicals in a controlled way to assure the fire doesn’t rekindle.

Rival Boeing currently has approval to fly certain aircraft as far as 5,5 hours from the nearest suitable airport in case of an emergency. When plans for the A350 were unveiled, Boeing said it didn’t intend to match Airbus’s goal.

On its A330-300 wide-body, Airbus already has approval to fly as far as 4 hours from the nearest airport under so called Extended-range Twin Operations, or ETOPS, rules.

Finnair, A350 European launch customer, details the route plans.

Airbus A350 XWB European launch customer Finnair will initially deploy its new aircraft on routes to Shanghai, Bangkok and Beijing when it enters service in the 2nd half of 2015.

Finnair, which has 11 A350s on firm order and another 8 on option, will subsequently roll the aircraft out to its Hong Kong and Singapore services in 2016.

Finnair will operate the aircraft in a 297-seat configuration including 46 business class seats in a 1+2+1 layout. Economy will feature a 3+3+3 layout, including 43 "economy comfort" seats with additional leg-room.

FAA Issues Special Conditions on Tire Failure Debris Penetration for A350. Meantime, Airbus completes the impact study for the wing.

The Federal Aviation Administration has issued a final special conditions rule [a Federal Register notice Docket No. FAA-2013-0907] for Airbus Model A350-900 series airplanes that will be effective on 8/September.

“These airplanes will have a novel or unusual design feature associated with fuel tanks constructed of carbon-fiber reinforced plastic (CFRP) materials located within the tire-impact zone, including the wing fuel tanks.

The ability of carbon-fiber composite material to resist penetration or rupture when impacted by tire debris has not been established. No current airworthiness standards specifically address this hazard for all exposed wing surfaces. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.”

Meantime, Airbus has completed the impact study for the A350 wing. Engineering consultancy Frazer-Nash has successfully completed a contract to accurately model impact damage on the A350 XWB.

The team analyzed particular areas on the leading edge and lower wing covers of the A350 XWB wings, with particular focus on the composite components.

The work involved Frazer-Nash conducting non-linear Finite Element Analysis to evaluate the predicted damage to the leading edge structures during bird impacts for different speeds and angles. The work also assessed the integrity of the wing lower covers in the event of tire debris impact.

Glyn Norris, Aerospace Business Manager at Frazer-Nash, “This project has been a great success. We were able to use our extensive modelling experience to support Airbus in successfully gaining certification”

What are those big jars onboard the A350 test aircraft used for?

During the Farnborough Airshow, the A350 prototype that was in display was visited for many people. And when visiting the interior of the flight test prototype, many questions were regarding the big grey-vessels that were onboard.

Crawford Hamilton, who works in the Airbus customer affairs team during the Farnborough Airshow explained what the big jars on board the aircraft were used for.

“We load them up with a mixture of water and glycol. That’s to stop them freezing and they simulate the loads in an airplane. We can move the centre of gravity of the aircraft by either filling them or taking the water mix out of them. And that means we can then start to look at how the airplane will look when it is loaded up with passengers or freight and understand what it does under those conditions.”

In ILA Mrs. Merkel asked about the jars too.

A removal in one engine during the A350 flight testing campaign. 420min-ETOPS clearance targeted for EIS.

Rolls-Royce reports smooth operation of the Trent XWB-84 during A350 flight testing .

“So far engine performance has been really good and reliable,” says Trent XWB Program Director Simon Burr, who notes that the single unplanned removal to date was a precautionary move to replace a faulty oil level sensor.

With the bulk of testing over, Rolls is focused on endurance-running to support ETOPS clearance—targeted at 420 min. from entry into service for the A350-900.

The work, conducted at Rolls’s  “60 bed”  facility at the NASA Stennis site in Mississippi, is aimed at demonstrating reliability across 3.000 simulated flight cycles.

The engine returned to Derby for tear down and inspection some weeks ago, following completion of a 3rd —and final—simulated diversion cycle.

ETOPS testing included runs at 30 min. per cycle. “We have been doing 60 cycles a day and ran through difficult weather for 43 hours continuously,” says Burr.

“We are in good shape and looking forward to entry into service.”
