PROGRESS IN AIR-STABILISATION FOR HYDROFOILS

Computer simulations of air stabilized hydrofoils (accomplished by admitting a controlled quantity of air to the fixed foil and strut parts for changing their lift) reveal a requirement for 4 percent more engine power with air stabilization to achieve speed levels attained in non-stabilized craft. In high-speed hydrofoils, above 57 knots, no extra power requirement is anticipated due to air-feed drag diminution. Air-control is also useful in the transition between full and partial cavitation by rendering the air fed foil controllable while the mechanical control method is ineffective.
