  • Vertical take-off and landing (VTOL) aircraft
    Patent number: 11643199
    Abstract: Vertical takeoff and landing (VTOL) aircraft, especially electric VTOL (e-VTOL) aircraft include a fuselage (which may include a pair of ground-engaging skids) defining a longitudinal axis of the aircraft, forward and aft pairs of port and starboard aerodynamic wings extending laterally outwardly from the fuselage and forward and aft pairs of port and starboard rotor pods each being in substantial alignment with the longitudinal axis of the fuselage. In specific embodiments, each of the forward and aft pairs of port and starboard rotor pods comprises a forward and aft pair of rotor assemblies.
    Type: Grant

  • Method and system for distributed electrical loads connected to shared power sources
    Patent number: 11198515
    Abstract: Methodologies to deal with electrical systems and power source failures for electric vertical takeoff and landing aircraft (eVTOL) design with distributed propulsion using multiple electric motors minimize required power source energy to perform an emergency landing procedure. Interconnecting electric loads and power sources in the “Ring Topology” concept considers combination of electric loads and power sources in order to reduce the impact on the loss of a power source, as well as to better utilize the remaining energy of the remaining power sources if any load becomes unavailable.
