Onboard Digital Recorders Improve Flight Vibration Tests
This article discusses a new approach to acquiring random vibration environment data during aircraft flight tests, and for using these data to improve random vibration test specifications. Traditionally, flight vibration data have been acquired using telemetry systems or tape recorders, which have many disadvantages. Recently, engineers at Eglin AFB have used state-of-the-art digital recorders ...
