Test rig data acquisition on Airbus A380 systems

Caesar test-rig control and data acquisition systems have proven their reliability throughout the Liebherr group, and have been recently used on the Airbus A380 flaps and slats hydraulics testing

Liebherr Aerospace is participating in the Airbus A380 project as system supplier of Secondary Flight Controls for Takeoff and Landing.

They comprise High Lift Systems (flaps, slats) as well as Airbrakes and Ground Spoilers.

High Lift Systems increase the lift as well as the drag of an aircraft to allow reduced takeoff and landing speeds.

Airbrakes contribute to loss of altitude during approach by decreasing lift.

Ground Spoilers are used for lift dump and drag increase during the touchdown braking phase.

In order to verify functionality as well as endurance, the complete hydraulic system for flaps and slats are tested on a full-scale system test-rig.

Real manoeuvres are simulated including the application of true air loads.

For many years, Caesar test-rig control and data acquisition systems have proven their reliability throughout the whole Liebherr group.

For this particular application, a MOPS system was used for the multi-channel function generation.

The parallel, synchronous data acquisition was performed in mixed mode, using the MOPS as well as a CAN-based system.

The complete application software for set-up, control and monitoring was created by Liebherr engineers using Caesar TestControl and micro-LAB software development tools, ensuring maximum flexibility for the maintenance and service of the complete system.
