"Can unclassified." Includes bibliographic references. "As part of the DRDC 03AC research project SHOLAS (Ship-Helicopter Operational Limits Analysis and Simulation), a sea trial is planned for a HALIFAX Class frigate where the airwake at the flight deck will be directly measured using an array of twenty 3D ultrasonic anemometers. The data will be used to validate model scale wind tunnel experiments and numerical simulations. The airwake measurements are to be performed for a range of relative wind angles in both calm and rough sea conditions. The document describes the required instrumentation, data collection, and test plan for the sea trial"--Abstract.
