PRELIMINARY PROPULSION PERFORMANCE ESTIMATES FOR AN 80-KNOT HYDROFOIL CRAFT

It is shown that a controllable-pitch propeller can be selected which will meet the takeoff and the maximum speed thrust ratio of 4.5 at 35 knots. It is recommended that auxiliary propulsion devices be investigated to facilitate hydrofoil takeoff.
