Transient air and surface contact vehicle
TLDR
In this paper, a transient air and surface contact vehicle for transporting a person has a fuselage structure for carrying a person and a vehicle support extends from the structure and abuts a surface and thereby supports the vehicle at a predetermined distance above the surface.Abstract:
A transient air and surface contact vehicle for transporting a person has a fuselage structure for carrying a person. A vehicle support extends from the structure and abuts a surface and thereby supports the vehicle at a predetermined distance above the surface. A buoyancy control device mounted on the structure and on the vehicle support provides for the buoyancy required to keep the vehicle afloat while stationary and at low speeds. At high speed the dynamic pressures generated at the bottom of the struts provide the supporting forces. A power source is mounted on the structure for moving the vehicle along the surface at the predetermined distance above the surface. A position control mounted on the structure produces a positive pitching moment to cause the vehicle to become airborne, a negative pitching moment to maintain the vehicle in surface-following contact with the surface and both moments to control the altitude of the vehicle when it is airborne. It is the pre-determined negative pitching moment that enables stable "open loop" pitch performance in the presence of high speeds and irregular surfaces.read more
