Document Type and Number:
Japanese Patent JP2000503216
Kind Code:
A
Abstract:
A hydrofoil and swim fin is provided for increasing lift and decreasing drag. In a preferred embodiment, the hydrofoil has a swept back leading edge and is oriented at a reduced angle of attack substantially transverse to the direction of movement of the hydrofoil. Structural reinforcement may be used to inhibit hydrofoil deformation during use, and a recess may be incorporated into the hydrofoil to direct fluid flow with respect to the hydrofoil surface. Torsional stress that acts on the hydrofoil when in use is also addressed.
