Airbus Test Rig
At the location Bremen (Germany) Airbus Germany operates with several different test rigs. The largest attempt plants are usually the High-Lift-Testrigs. The landing flap and/or slat systems of an airplane with all drives are built up in full-scale.
The task of the test rig automation basically consists in the control of hydraulic and pneumatic cylinders, which are used for the simulation of aerodynamic air loads. These air loads depend on the traverse path of the landing flaps and on time. In addition to the load simulation, the test rig automation also controls the supply of the test rig with mineral oil and the supply of the airplane-lateral drives with Skydrol. Furthermore, extensive monitoring is necessary.
These monitoring mechanisms are necessary, in order to protect the service personnel as well as the high-quality and original components, often only available as prototypes. All test parameters are redundantly seized and examined for plausibility. Forces, pressures and positions are supervised on valid values; gradients are limited. In addition, the test rig is secured by light barriers and door contacts, so that it can be operated securely.
The complete control is based on a industial PC as control computer, an operator PC for software development and translation with Matlab, and several windows clients for visualization. All computers are supplied via UPS. The operator's computer has mirrored hard disks. The control computer works diskless and boots from the operator's computer.
The control program was developed using the EtherLab®-Technology.
