With a total of 2 patents, his work showcases innovative designs that enhance aircraft performance and versatility.

Latest Patents

One of Billingsley's notable patents is for a VTOL aircraft that features both fixed-wing and rotorcraft configurations. This aircraft design includes an airframe with a fixed-wing section and multiple articulated electric rotors. Some of these rotors are variable-position rotors that can switch between different operating configurations based on their position. The first configuration allows for vertical flight, generating primarily vertical thrust, while the second configuration enables horizontal flight, producing horizontal thrust. The control circuitry in this design independently manages rotor thrust and orientation, allowing for advanced thrust-vectoring maneuvering. Additionally, the fixed-wing section may incorporate removable wing panels, enabling the aircraft to adapt to various missions.

Another significant patent by Billingsley involves a variable pitch rotor assembly for electrically driven vectored thrust aircraft applications. This invention utilizes articulated, variable-position electric rotors that can transition between different operating configurations. The design also includes variable-pitch airfoils or blades, which are essential for generating vectored thrust. The control circuitry in this aircraft generates signals to manage rotor position and blade pitch, facilitating smooth transitions among flight modes, including VTOL and forward flight. This innovation allows for tailored thrust-vectoring maneuvering, optimizing the aircraft's performance.
