  • Publication number: 20210016875
    Abstract: An Electric Vertical Take-off and Landing (EVTOL) Passenger Air Vehicle (PAV) using a plurality of electric motors positioned concentrically about the passenger compartment and utilizing ducted turbines to produce thrust allowing the vehicle to take off and land vertically and fly without the use of aerodynamic wings. Utilizes a plurality of independent electric battery powered motors providing sufficient thrust to ensure the vehicle can hover and complete a safe landing despite a loss of thrust from any two adjacent motors and up to half of the motors, if non-adjacent, by utilizing redundant onboard flight control systems to vary motor torque as need to maintain steady, controlled flight. Design utilizes a pivoting seat for passenger comfort as well as shock mounting of the seat for safety. Ingress and egress are facilitated by integrated folding air stairs. The turbine fairing is designed to be rapidly manufactured as two parts, as upper and lower shells, using a composite forging process.
