Ignition controller test

System for functional and parametrical test of ignition systems for gas turbine engines

Test measurements of control functions, high voltage parameters, and arc quality

System for functional and parametrical test of ignition systems for gas turbine engines. Measurements on control functions, high voltage parameters, and arc quality. The system tests a single controller at a time but can interface with different types using a fixturing concept developed by the customer.

The system is serviceable via a remote connection.

Software based on TestStand and LabView

Based on Teststand and Labview using a modified sequential process model. User Interface with emphasis on graphing and displaying the measured parameters on each unit.

Product diversity handling handles varying test limits and stimuli that change depending on the specific variant of the UUT.

Data logging in a custom formatted SQL database that leverages DSE’s Statistical Process Control package.

Product Diversity handling, data logging, and the Graphical User Interface (GUI) are implemented using DSE’s EasyStand toolbox.

GPIB instruments and unique mechanics for arc-chamber

The customer selected GPIB instruments because of known good performance experience from their R&D laboratories - unique mechanics for controlled arc-chamber with the possibility to change the gas media in the arc chamber.
High voltage probes enable measurement and analysis of the arc current via the GPIB scope.
High-voltage connections between the test rack and the fixturing system are handled by rugged connectors that ensure signal integrity.
