Test Solutions: Linear Actuator End-Of-Line Testing

Challenge

Create a universal test system to test various aircraft linear actuators to ensure proper stroke, load, current draw, and other operational parameters are within specification.

Solution

A custom 500lb load test system built from off-the-shelf components and based on the National Instruments NI cRIO-9063 platform with LabVIEW applications for control, safety monitoring, data collection, and reporting. 

Summary

Linear actuators are used throughout aircrafts to perform actions that are both flight (e.g., landing gear deployment) and non-flight (e.g., cargo bay door release) critical. Actuators are typically electrically driven and apply a range of forces to move a piece of the aircraft into a desired position. Components must be tested through their range of expected operation and at safety limits that exceed the norm.

Test Solutions: High Voltage Dielectric Tester

Challenge

Create an accelerated life test solution to automate configuration, control, and failure detection of high voltage dielectric materials.

Solution

The National Instruments Compact RIO (cRIO) platform with integrated real time embedded controller and FPGA Scan Engine capabilities programmed with LabVIEW and the LabVIEW Real-Time module.

Summary

All electrical insulation materials fail at some level of applied voltage. “Dielectric strength” is the maximum measured value of the electric field a material can withstand before breakdown occurs.

Test Solutions: Improving and Refactoring Third-Party Legacy Software

Challenge

Add new measurement capability to an existing legacy software application with concern for code reuse, robust design, and long-term maintenance.

Solution

A legacy version of LabVIEW 5.1 Professional Development System, Traditional NI-DAQ driver, and legacy E-Series multifunction DAQ measurement hardware.

Summary

During the life cycle of a product, manufacturers often find that the test and measurement requirements change. A product may be used in new or more precise applications. Corner use cases not previously tested may now cause failures and changing requirements pose a particularly difficult issue for mature products.
