Abstract
The Halifax Class frigates are in the process of a mid-life modernization. The engineering changes made to the ships during the refit have resulted in significant superstructure modifications affecting both the airwake over the flight deck and the accuracy of the mast-mounted anemometer system. This requires that the CH124 Sea King Ship-Helicopter Operational Limits (SHOL) envelope be re-certified for operation from post-refit ships. This re-certification will involve extensive wind tunnel experiments conducted by the National Research Council (NRC) in addition to a limited sea trial program. This report summarizes DRDC’s contribution to the sea trial conducted on HMCS FREDERICTON in December 2013 that was part of this effort. The ship was instrumented with supplementary anemometers at the bow and mast to help validate the wind tunnel experiments. Aircraft operations were conducted by Aerospace Engineering Test Establishment (AETE) as part of the SHOL development with support from the prototype Flight Deck Motion System (FDMS) developed by DRDC Atlantic. Analysis and interpretation of the resulting data set is presented in separate reports by AETE and NRC.
