HYDRODYNAMIC PERFORMANCE OF THE MODEL OF A VARIABLE AREA WATERJET INLET DESIGNED FOR A 200 TON, 100 KNOT HYDROFOIL SHIP

The primary objective of this study was to assess the state-of-the-art in waterjet inlet design capability for high-speed hydrofoil applications. A contract was let for the design of a variable-area, strut-pod inlet for the waterjet propulsion system of a 200 ton, 100 knots hydrofoil ship. A basic requirement of the design was that the inlet must provide cavitation-free operation for prescribed flow-rates at both the 100 knots cruise and 35 knots take-off speed. The most up-to-date design procedures and performance prediction techniques were to be used.
