Abstract:

A trial to measure ship motion and airwake has been carried out aboard an Adelaide class FFG-7 frigate. Data processing procedures are described which take the raw measured data from the data acquisition system, convert them to imperial units, and correct the Gill anemometer data for non-cosinusoidal response to angle-of-attack variation. A method of salvaging data corrupted by high frequency signals is also presented, along with a discussion of further data processing required to enable the results to be used as a data base for a computer simulation of the Sikorsky S-70B-2 helicopter and FFG-7 combination.
