High lift systems put to the test for A380

Liebherr-Aerospace is participating in the Airbus A380 project as system supplier of secondary flight controls for takeoff and landing.

These 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 reducing 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's 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 multichannel 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 setup, control and monitoring was created by Liebherr's own engineers using Caesar's TestControl and u-Lab software development tools, ensuring maximum flexibility for the maintenance and service of the complete system.
