Abstract:

This report summarizes the effort to review existing documentation and at-sea test results and assess performance of the SLICE ship control system. At-sea data taken by NSWC-Carderock, Lockheed Martin and documentation provided by Lockheed Martin provided the baseline information to conduct the assessment. The assessment focused on the SLICE ship control hardware and software including the control surfaces actuation system motion sensors control computer and control algorithms. Seakeeping performance improvement with ride control was not demonstrated during NSWC at-sea testing. Lack of recording of the position command signals to the control surfaces prevented a detailed analysis control surface actuator performance. Analysis of selected test runs from the Lockheed-Martin at-sea testing effort identified some problem areas as detailed in this report.
