The 2003 AMV 211 VTOL experiment with ducted-fan propulsion. A 450hp turbocharged Mazda rotary driving a belly-mounted, 94″ five-blade prop. Wings were set at an angle to the fan, and the fuselage itself provided lift. Take-off was with the fan horizontal, blowing downward. As the ship tilted forward, wings would provide lift and the fan would then start blowing rearward through a system of louvers. For landing, the process was reversed.
