Relative Wind Measurements on an FFG-7 Class Frigate

Abstract

During trials on HMAS Adelaide in March 1990, two tri-axial Gill anemometer arrays were mounted abeam of the helicopter hangars to provide information about the air flow in the vicinity of the flight deck. However, concerns were raised about the accuracy of the ship anemometers, and a comparison has therefore been made of the air flow measurements recorded from the Gill anemometer arrays with those recorded from the ship anemometers. Good agreement has been observed for certain relative wind directions, and this indicates that the ship anemometers were accurately measuring the prevailing wind velocities.
