Abstract:

Carrier landing operations are often suspended due to severe deck motions. Attempts to compensate for deck motions require detailed knowledge of the nature of such motions over short time intervals because of landing approach typically lasts only 30 sec. The report contains the results of examining ship motion amplitude and frequency characteristics over short time periods in rough sea conditions. Included are histograms and power spectral density plots of pertinent recorded ship motions. These are presented for several short intervals over a three hour period so that a variation of motion characteristics with time is evident.
