ASYMMETRIC HYDROFOIL PROPULSION METHOD AND APPARATUS

摘要

An asymmetrically arranged hydrofoil and propeller system is disclosed for improving the speed and lift of watercraft such as amphibious vehicles. When the vehicle is propelled through water by propellers, a downwash of water from the upper surface of the asymmetrically arranged hydrofoils is intercepted by upwardly moving propeller blades which improve the speed, lift and efficiency of the watercraft.
