Description
Summary:A Mission Data Recorder (MDR) was designed and built by the Coast Guard R&D Center to support the Operational Test and Evaluation (OT&E) of the 47-FT Motor Lifeboat (MLB). The OT&E was under the overall direction of the Motor Lifeboat Replacement Acquisition Project Manager, Commandant (G-AMB). The purpose of the MDR was to collect both short-term event data and long-term vessel motions data in an autonomous manner. Some significant events have been recorded, including a 137-degree roll event, during which the values of roll, pitch, yaw, engine RPM and rudder angle were recorded. Testing of five 47-FT MLBs will continue for at least another six months. The MDR will record significant roll events and long-term vertical acceleration data for use in a crew fatigue study.
