Propeller Inflow Measurements on an Air Cushion Landing Craft Vehicle (LCAC)

Abstract

Air inflow velocity data are presented for the starboard propulsion propeller of an LCAC vehicle. Data at various radial and angular locations centered on the propeller shaft are shown for two stations upstream of the propeller but behind the LCAC superstructure. Test conditions include multiple speeds over water as well as bollard conditions at full power. Severe velocity deficits are found in the lower outboard quadrant of the inflow, and these deficits become more severe closer to the back face of the craft superstructure.
