The Influence of Ship Motions on Operations of SH-2F Helicopters from DF-1052-Class Ships:Sea Trial with USS Bowen (DE-1079).

摘要

A 4-day sea trial was conducted with the USS BOWEN (DE-1079) in an attempt to extend the existing operating envelope of SH-2F helicopters from DE-1052-Class ships. Participants included teams from the Naval Air Test Center, the Naval Air Engineering Center, and the Naval Ship Research and Development Center (NSRDC). The present report concerns NSRDC measurements of ship motions, sea conditions, and wind conditions and their relationship to the degree of difficulty experienced in aircraft operations. Air turbulence or gustiness was found to be somewhat more important for the relatively small SH-2F helicopter than ship motions although the maximum double amplitude roll of 19 degrees and maximum double amplitide pitch of 5.6 degrees did produce difficulities. However, these motions did not provide the limiting conditions under which safe SH-2F operations can be performed. The highest sea encountered during the trial was a low State 5. Additional trials in higher seas are required to establish the highest acceptable motion limits. The present results contain several important operational implications. (Author)
