Due to the events of 09/11 civil aviation is going through a very difficult
market phase. A strong decline in passenger numbers has caused the airline
companies to exercise restraint in buying new aircrafts.
The resulting cost pressure is forcing air-craft manufacturers and
their suppliers into a process of con-centration which apparently
has not come to an end yet.
Despite this situation there are outstanding projects like the construction of
the large aircraft Airbus A 380 and the plans for the 747 Advanced by Boeing,
which show that the development of new passenger aircrafts continues at
full stretch. Also in the future innovative concepts will succeed in
finding their market.
To be capable of innovation air-craft manufacturers and their suppliers
are compelled to shorten their development cycles and to keep their
development costs as low as possible a task which, against the
background of increasing technical complexity, is almost impossible
to fulfill without breaking new grounds.
So, apart from the important role they play in product design by supporting
the business processes: often, it's the IT systems that open up new options
for introducing improved concepts.

| Test and Measurement in Aircraft Construction
|
|
Measuring and testing are core elements in all phases of aircraft
construction from modeling to testing of individual components and
systems as well as their integration, and, finally, in validation
and quality control. Extensive test scenarios are developed and
executed, the interaction of components and subsystems must be
verified and then be validated. Systems by Werum are capable of administering any
kind of measurement and test data and of handling the associated information management.
Thus, they are ideally suited to support engineers in every phase of the development
process.
While the Test Data Management System DAVIS acquires, processes,
and stores the data produced in measurement and testing procedures
and archives it for subsequent analysis, the Information Management
System HyperTest® provides the results of testing and the associated
information simultaneously across departments. That means, HyperTest®
is well suited for the efforts of aerospace industry to speed up
development processes by shortening the information flow and by optimizing workflows.

In the field of aircraft construction platform con-cepts, as they have been
fairly common in the automotive industry for some years already,
become increasingly widespread. Reusability of components and
systems and their adaptability fully com-plies with the suppliers'
special interest as it saves them a considerable amount of development costs.
With the Information Management System HyperTest® Werum equips the developer
with an apt instrument to search existing measurement and test data by
different aspects and to integrate the data into the development process.
The developer can check whether an intended measurement to exa-mine a
component or assembly has been performed before and whether the results
are applicable to the current situation. So, the information of previous
tests and all relevant test conditions can find their way back into the
development process.

The systems developed by Werum are open systems which smoothly
integrate into the lifecycle-oriented workflows and organizational
structures of aero-space industry. To ensure communication with
tomorrow's tools DAVIS provides open interfaces for data acquisition
as well as for analysis or visualization. There are pre-configured
interfaces to connect standard systems. HyperTest® places the data of
distributed systems available in any kind of data type and facilitates
the further processing by common analysis tools.
Test data management systems must be highly flexible and configurable
to give the developer a free hand in defining the test design.
At the same time, configuration is to be made easily and quickly.
Therefore, Werum examines every customer's specific range of
testing tasks, identifies recurrent test configurations and
analyzes test scenarios in order to standardize specific test
set-ups and procedures. Efficient utilization of resources and
defined workflows make it possible, for instance, to extend
the productive use period of test benches considerably.

Test Data Acquisition and Control for Test Benches
Test benches are operated in continuously changing configurations
and with different layouts and media. They are used to examine material
properties, optimize the processes in aircraft or other engines,
or research new technologies. Especially for such purposes Werum
has implemented a flexible test data acquisition and control system
based on the product DAVIS for the Institute of Space Propulsion of
the German Aerospace Center, DLR. This system is able to deal with a
wide range of physical parameters and various scenarios. To ensure short
set-up times for changeovers, the user can easily modify the software
parameters to adapt the system to the current requirements. Although
it initially was established for basic space propulsion research in
aerospace industry, the concept can also be transferred to jet
engine test beds for the development and maintenance of aircraft engines.
Werum's vast experience is a strong benefit for the usage of
DAVIS as wind tunnel control system, where the focus is on data
cquisition and sequence control in testing. DAVIS is applied to
operate the wind tunnels of Toyota Motorsport and Audi..
Test Data Management
On board the DLR's research aircraft ATTAS (Advanced Technologies Testing
Aircraft System, a twin-jet VFW 614) DAVIS performs the acquisition, storage,
distribution, and visualization of data generated during the execution of
experiments. Within the scope of developing an integrated Air Traffic
Management (ATM) the ATTAS aircraft is employed to validate and assess
the air traffic control systems and procedures.
Under the overall management of Airbus Bremen the technology program ProHMS,
which does research on multifunctional highlift systems, has produced effective
concepts for wing flap systems leading to an improved performance in all flight
phases. Using the product DAVIS as basis, Werum has implemented the central test
data management system for this project.
The ProHMS research project benefited from the experience gained in setting up CASIV, an innovative test environment.
CASIV stands for 'Cabin
Systems Integration and Verification' and is a system designed to simulate
and test complex interacting cabin systems as they are used on the airbus
A 380 in every stage of development. For CASIV Werum has developed the
central test data management system with archiving component, interfaces to test
engines, test generation tool and display / operating systems.
A great challenge the TDM system and its interoperability have to face is
the heterogeneous world of operating systems, in which realtime applications
have to cooperate with standard analysis systems based on Windows.
Due to its flexible and expandable architecture the innovative CASIV test
system can also be transferred to systems other than cabin systems.
While the CASIV project focuses on integrating cabin systems, an
individual system is tested in the DEESi project (Decoder / Encoder Unit Electrical Simulation).
DEESi is one of a total of 20 system integration benches (SIB) applied in the CASIV
project for testing and integrating individual subsystems.
Within the scope of the project HLSDS (High Lift System Development Simulator)
acceptance are performed for the high lift systems of the Airbus A 380.
On the scene again: the TDM by Werum. The measured data thus collected are
visualized and stored in realtime. Subesequently, analysis operations can be
executed with DIAdem.
The test data management (TDM) system is a functional core component of the
highly dynamic test system, which can be flexibly adjusted to the various
testing demands. That means, out of several thousand available signal
channels the ones currently required are selected, the appropriate test
description is generated and transferred to the realtime test systems.
In addition to the actual measurement data of several megabytes
per second, the TDM system also acquires all relevant data on test
procedures and system configuration. It administers and archives
this data and places it available to the users in online and offline
display and for analysis purposes.

In all stages of the process of developing components, modules, and systems
huge amounts of data are produced. Their availability is of highest significance.
Whenever measurements are taken, extensive additional information has to be
managed along with the actual results. The open solution platform HyperTest®
enables logical organization and query of any information across departmental
limits or even across corporate limits.
HyperTest® supports approaches of aerospace industry, such as "Concurrent
Engineering" or "Simultaneous Enginee-ring", which have the target to speed
up parallel development processes by establishing new information channels
while focussing on the overall task of measuring and testing.
In view of constantly increasing demands, shortened cycle times and
the need to reduce costs companies look for innovative ideas and new
concepts to boost their efficiency. HyperTest® as future-looking platform
supports the goals of the enterprises.
