A major construction project to build a 600,000 sq ft purpose-built factory in east Belfast is nearing the end of its first phase.

Early in 2011, production of Bombardier Aerospace's CSeries aircraft wings is due to get under way early in the all-new factory, with this week, the CSeries family of aircraft being shown off at the Farnborough Air Show.

On top of news that Bombardier has recorded firm orders for a total of 90 CSeries aircraft, it emerged this week that engineers at the company have completed what they are calling the ultimate load test on the CSeries aircraft composite demonstrator wing.

As part of the complex research and development programme, a full-scale, three-quarter span pre-production demonstrator wing was assembled, which has been undergoing rigorous testing.

Loads were progressively increased on the demonstrator wing in order to simulate aerodynamic, landing gear and engine pylon forces, until ultimate loading was successfully achieved.

"We are now assessing the data from the thousands of strain gauges, and are delighted with the results we've obtained so far," said Michael Ryan, Vice President and General Manager, Bombardier Aerospace, Belfast.

"The data will help us to optimize the final production design for weight and performance. This successful demonstrator test confirms that our Resin Transfer Infusion process is an excellent means by which to manufacture the large primary structural elements of the composite wing torque box for the CSeries aircraft," he said.

Having successfully achieved ultimate loading, Bombardier engineers are continuing to carry out further tests on the demonstrator wing to assess the wing's capability of sustaining various types and levels of damage.

This will also allow them to ensure that repair systems are proven before the aircraft enter into service.
