Amfax delivers a new generic ATE for testing aerospace pilot display unit modules. The system enables testing of all module types using the same tester
Amfax have recently designed, built and delivered core PXI based automated test systems to a major aerospace manufacturer. The brief was to come up with a design that could test all the pilots display unit (PDU) modules using a single automated tester. Previously the client had a number of ATE's that each tested just one module. This meant that previously the client not only had to invest in multiple testers but had to obtain support for each unit separately. The ATE used a fully loaded PXI rack to house all of the instrumentation needed to ensure test coverage of all the measurements required for each module. The modules tested included a solar cell, electronic display, interface unit and auxiliary PCBs.
Key benefits of Amfax's involvement
The resulting system was a generic test platform which allowed the end customers to strip and test Eurofighter hydraulic components without having to send them back to the manufacturer.
This vastly reduced the costs for supporting operational aircraft.
System safety and design innovation were key
Operator safety was a key consideration for the hydraulic test rig. Hydraulic power packs capable of delivering 360bar pressure or 180 l/m flow could do serious damage. Our solution's design addressed these concerns
System software and hardware used
LabVIEW was used as the primary development language for this project and delivered the following benefits :
The real time module for LabVIEW allowed us to make use of PXI RT hardware, broadening the scope and capability of this system.
Each type of hydraulic component needed its own test sequence with step by step limits and custom control conditions. TestStand was the natural choice for this and offered these benefits :
Test Bench hardware included
