E - Dwight Filley's TWO Air Screws 2008-2010
INTERNATIONAL HYDROFOIL SOCIETY'S ALBUMS > E - Dwight Filley's TWO Air Screws 2008-2010
Dwight Filley created two hydrofoils propelled by a human-powered airscrew. Neither flew well and the air screw was a danger to the pilot. Of course the performance was dominated by prevailing winds. The project was abandoned in favor of water-screw propelled hydrofoil boats.
