RESPONSE PREDICTIONS OF HELICOPTER LANDING PLATFORM FOR THE USS BELKNAP (DLG-26) AND USS GARCIA (DE-1040)-CLASS DESTROYERS

Motion-response predictions of the helicopter landing platform for the USS BELKNAP (DLG-26) and USS GARCIA (DE-1040)-Class destroyers are presented. Predictions have been obtained by a computer- implemented procedure, which calculates response statistics at an arbitrary point on a ship in long-crested, irregular seas. The procedure is based on ship-motion theories in the state of the art. Results are presented for several ship speeds, states of sea, and ship headings-ranging from head to following waves. Existing envelopes of helicopter operations are discussed, and suggestions are made, based upon the results of this study, for the listed new operational envelopes in higher states of seas: responses other than roll, e.g., vertical response at the landing platform, must be considered; quartering sea landings may be safer than bow sea landings; and, to increase safety of operations, BELKNAP should be stabilized in roll.
