Ducted fan VTOL vehicles

A ducted fan air flow vehicle comprising:

• a fuselage and associated air flow control surfaces;
• a first duct disposed forward of a cabin payload area of said fuselage and a second duct disposed aft of said cabin payload area, each of said first and second ducts having a peripheral wall, an upper inlet end and a lower outlet end, and each enclosing a fan arranged to force surrounding ambient air to flow therethrough in a direction from said upper inlet end to said lower outlet end of said first and second ducts, respectively, thereby creating a vertical lift force directed along respective duct flow axes;
• at least one adjustable opening in a forward-facing side of the peripheral wall of said first duct and at least one adjustable opening in a rearward facing side of the peripheral wall of said second duct;
• wherein said fuselage between said first and second ducts is aerodynamically shaped to produce additional lift force during forward vehicle motion, said fuselage tilted upwardly and said lower outlet end of said first duct configured such that a lower surface of said fuselage is substantially aligned with flow exiting said first duct.
