Design of Test Equipment for XWB Engine Controller

We worked with Aero Engine controls providing the necessary resource to successfully and efficiently design the necessary equipment required for Production assurance.

Two types of test rig are required for this purpose:

1. A full production acceptance test system which includes signal simulation and measurement resources.

Covering support and simulation of the following:

  • CAN
  • AFDX
  • Proximity Sensors
  • LVDTs
  • Speeds
  • Torque Motors
  • Differential Pressures
  • Permanent Magnet Alternator

2. An assembly test rig which carries out basic functional testing using a set of fixed loads to check that the unit has been assembled correctly

The test rig was constructed with a view for maximum flexibility for future changes to the project. This was achieved by allowing space within the rig for adding extra instrumentation and giving good airflow to all areas of the rig.

The basis of the design was a PXI rack for instrumentation and control with the load and conditioning scheme custom PCB’s being designed in a modular fashion to allow for easy replacement.

Within the 19inch rack format a generic lay out of all the instrumentation was used so that the lay out was the same across the two rig types leading to easier maintainability.

This enabled the test system to be accessed from all sides and the components within could be easily replaced and upgraded when and where necessary.

Our engineer managed the entire design cycle of the test rig taking it from the initial specification to the release of the completed automated test system to the production floor completing all required validation and type approvals for the system.
