Variable Geometry Vertical Takeoff and Landing (VTOL) aircraft system |
| abstract |
A variable geometry vertical takeoff and landing VTOL aircraft system can transport passengers from a point of departure to a destination via partially or fully autonomous flight operations. The VTOL aircraft system can operate in hover-based ascent/descent mode, level flight cruise mode, and transition modes between these two modes. Thrust may be provided by a ducted propeller unit hinged relative to the fuselage; the thrust source may be steered for ascent/descent, transition, and cruise for controlled ascent by hingedly connecting the thrust source to the airfoil struts of the fuselage , descent and cruise. More precise thrust control can be achieved by further articulation of the annular propeller duct relative to the airfoil strut. The airfoil struts and propeller ducts may exhibit an airfoil-shaped or variable segmented cross-section to maximize achievable lift. |
