Hydrodynamic Performance of the Model of a Variable Area Waterjet Inlet Designed for a 200Ton, 100 Knot Hydrofoil Ship,

摘要

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.
