Airbus Bremen:
Tests of the Control Computers for High-lift flaps
of the Airbus A380
|
|
| |
|
|
The Airbus A380 is equipped with special high-lift slats and flaps which ensure the required lift at low flight speeds, such as when taking off or touching down. These high-lift slats and flaps are controlled by a Slat/Flap Control Computer (SFCC). To ensure the functioning and functional safety of the control computers, extensive component tests are required. All inputs and outputs of these control computers are driven through a simulation environment called the High-Lift System Development Simulator (HLSDS).

| Controlling and Monitoring the Test Sequences |
|
|
At the hub of the technical tests of the computers controlling the innovatory slats/flats actuator systems is Werum's Test Data Management System (TDM). In the course of the tests, up to 2500 measuring channels are sampled at 1000 Hz, and the acquired data is saved simultaneously in the TDM. By using a central GUI the users are able to control and monitor the complete test sequence on screen - beginning with the activation of a recording instance on the TDM, through to setting up the test configuration for the test system, and starting the test script right up to completing the test and deactivating the recording instance again. On the central GUI the user can directly define the individual test configurations. These are managed in a CVS, in a way completely transparent to the user. In addition, the central GUI shows the states of the underlying systems and the hardware usage, such as CPU load and hard disk space used.

| Data Display and Analysis |
|
|
The measurement data can be displayed online while the data is being recorded on an individually configurable user interface. The interface also enables users to intervene in the simulation process through commands. To facilitate display and control, operating elements such as buttons, sliders, alphanumerical entry fields and X/Y-axis diagrams are provided. User-specific display and operating panels may be saved and then be loaded at a later time.
The TDM ensures that the data is consistently collected and saved. Through an analysis interface the user can access stored data for time or channel-based retrieval. As the analysis tool, DIAdem 9.0 from National Instruments is used. This tool accesses data in the TDM by means of a plug-in especially developed for this purpose.

| Archiving Function |
|
|
|
An integrated archiving function transfers saved data automatically to DVD media. As a DVD jukebox is used, 550 DVDs are available to the fully automated archiving system in the implemented system configuration. The access to and the analysis of data archived on DVDs is possible without any additional user interaction.
