Extract

Three basic problems encountered in the use of propellers on hovercraft are erosion, corrosion and noise. The tip velocity of a 9 ft diameter hovercraft propeller can exceed Mach 0·8, giving rise to fairly high noise levels. When operating over shallow water the propeller may run in a fine suspension of sand and sea water, which at these high speeds is akin to operating in a highly corrosive vapour blast cabinet.
