Title: Innovations by David F. Gebhard
Introduction
David F. Gebhard is an accomplished inventor based in Northport, NY (US). He holds a total of 3 patents that showcase his expertise in the field of aerospace engineering. His innovative designs focus on unmanned aircraft and vertical takeoff and landing (VTOL) technologies.
Latest Patents
One of his latest patents is for an unmanned boom/canard propeller VTOL aircraft. This design features dual turbo shaft engines driving contra-rotating propellers. The aircraft includes a bow plane that provides pitch control during normal cruising. The contra-rotating propellers generate a slipstream for the wing and tail sections, allowing the aircraft to hover without complicated tiltable rotor or jet assemblies.
Another significant patent is for a tilt wing VTOL aircraft. This aircraft has an upper wing that is pivotally mounted on the fuselage, allowing it to rotate from a cruise position to a hover position. The design includes forward and aft cutouts that produce a vortex along the sides of the fuselage. This vortex enhances the wing's tolerance to angle of attack and reduces the need for propeller bending of the airflow during mid-transition speeds.
