Abstract

The Prognostic Center of Excellence at NASA Ames is currently researching actuator prognostics, specifically in the application of electro mechanical actuators (EMA’s). Cal Poly ME students Michael Koopmans and Catlin Mattheis and EE student Austin Lawrence have chosen to undertake the task of building a test stand that will be flown in flight while testing EMA’s specific faults. A stand was designed to fit inside a standard 19” rack, take power from the aircraft 3 EMA’s, a computer, data acquisition, and electric magnets switches are powered. A MIL STD 1553 interface is present to allow fault injection. Vibration and temperature data can be recorded during experiments. However, due to time constraints, not all tests were completed and the control system needs optimization. The stand is 90% complete and with a little more work the test stand should generate interesting and valuable data to compliment the Health Systems Management algorithms relating actuator faults and numerical relationships.
