Bombardier Aerospace, Belfast has chosen Moog Industrial Group to supply an aerospace test system to undertake a full-scale structural test on the CSeries aircraft advanced carbon fibre wing.
The system will be used to carry out fatigue testing of the composite structures of the wing. This testing forms part of the CSeries aircraft certification test programme. Bombardier has manufactured a wing for testing that is similar to the production article, but without the wing tip, systems and control surfaces.
The test system uses structural test actuators with servo valves and has an active load abort system.
This is an independent multi-channel safety system. In the event of a primary loading system failure, it uses a Moog machine controller to take the load off the structure in a synchronised way while maintaining the desired load distribution. This prevents undesirable and unrepresentative loading being applied to a unique structure that has already accrued valuable fatigue testing hours.
