EXPERIMENTAL STUDY OF PILOT VISIBILITY FROM A VTOL AIR/SEA CRAFT NEAR THE OCEAN SURFACE.
Abstract
A major problem associated with the operation of a VTOL air/sea craft near the ocean surface is the impairment of pilot visibility. Clouds of spray, generated by downwash impingement on the water surface, surround the aircraft and block the pilot's view. The objective of the study was to determine promising methods for alleviating the problem. A model-scale experimental facility was constructed to study the details of spray generation and the characteristics of the resulting spray pattern. Several spray alleviation devices were then designed and tested. To evaluate their effectiveness, a technique for quantitative measurement of visibility was developed. Comparative tests were conducted with and without the spray alleviation devices. (Author)
