Abstract
A water jet inlet as used in a surface effect ship, cavitation free environment is provided of a fixed round or rectangular inlet geometry, within the confines of inlet velocity ratios pertaining to the ship velocity immersion design profile. An additional embodiment is disclosed that enables the instant invention to operate at a range of drop fractions, including negative drop fractions, and allows for a truly flush inlet, resulting in minimizing the drag of the ship and potential ingestion of large floating debris.
