AN EXPERIMENTAL STUDY OF PILOT VISIBILITY FROM A VTOL AIRCRAFT IN OVERWATER HOVER.

Abstract

A test program which investigated in small scale the phenomenon of spray generation and the resulting impairment to pilot vision when an in-line VTOL configuration, such as the LTV XC-142A, is in low-altitude overwater hover is described. Also given are the improvements to pilot vision when deflectors are used to divert the spray from principal regions of interest to a pilot. A device in close proximity to the fuselage is, at best, only locally effective. The major conclusion is that a deflector positioned at the water surface cavity produced by the slipstreams of the propellers can be very effective in reducing spray. The use of such a deflector, however, may present potential problems affecting hover performance and spray ingestion through the propeller plane. (Author)
