Abstract
A near surface vehicle including a vehicle body including a nose section having a canard with lift and pitch control. The vehicle body including a cockpit or cabin with a main wing mounted adjacent or above the cabin and including ailerons for lift and roll control. The vehicle body further including a tail section having a tail surface and a thrust air fan for providing air for lift and propulsion of the vehicle. The vehicle including an air diverter for deflecting air into a controllable lift area for initial lift and air deflectors or rudders for controlling vehicle direction and vehicle reverse thrust.
Claims19
A near surface vehicle, comprising:
- a vehicle body including a nose section, a passenger cockpit and a tail section, said nose section including canard means, said canard means including elevator means for lift and pitch control and endplate means for increasing lift under ground effect conditions;
- said vehicle body including a main wing, said wing including aileron means for lift and roll control and endplate means for increasing lift under ground effect conditions;
- said tail section including a tail surface, said tail surface including elevator means for auxiliary lift and pitch control, endplate means for increasing lift under ground effect conditions, and including thrust fan means and means for powering said thrust fan means for providing thrust air for said near surface vehicle;
- said vehicle body including a pair of rigid hull sidewalls and means for forming a lift area between said sidewalls including means for adjusting said lift area;
- means for diverting a portion of said thrust air from said thrust fan means into said lift area to provide an initial lift force;
- and
- means for laterally directing said thrust air to control the direction of said near surface vehicle.

A near surface vehicle, comprising:
- a vehicle body including a nose section, a passenger cockpit and tail section, said nose section including canard means, said canard means including elevator means for lift and pitch control and endplate means for increasing lift under ground effect conditions;
- said vehicle body including a main wing, said wing including aileron means for lift and roll control and endplate means for increasing lift under ground effect conditions;
- said tail section including a tail surface, said tail surface including elevator means for auxiliary lift and pitch control and endplate means for increasing lift under ground effect conditions, and including thrust fan means and means for powering said thrust fan means for providing thrust air for said near surface vehicle;
- said vehicle body including a pair of rigid hull sidewalls and means for forming a lift area between said sidewalls including means for adjusting said lift area, including forward flap means and aft flap means, said aft flap means including means for controlling the position of said aft flap means to form and control said lift area, said forward flap means including means for locking said forward flap means against said vehicle body to substantially eliminate said lift area and to decrease drag after an initial lifting phase, after which said vehicle is travelling under ground effect conditions;
- means for diverting a portion of said thrust air from said thrust fan means into said lift area to provide an initial lift force including adjustable deflector means for diverting the desired portion of said thrust air into said lift area through a passageway formed in said vehicle body into a forward portion of said lift area against said forward flap means in an initial lifting stage;
- and
- means for laterally directing said thrust air to control the direction of said near surface vehicle including movable vane means to direct said thrust air to control said near surface vehicle direction.
