  • Patent number: 11628955
    Abstract: A tethered uni-rotor network of satellite vehicles, is made up of a central hub with multiple tethers radiating outward in a hub-and-spoke arrangement. Each tether attaches to a satellite vehicle; each having lifting airfoil surfaces, stabilizers, control surfaces, fuselages, and propulsion systems. The entire system operates in a persistent state of rotation, driven by the propulsion units on each satellite vehicle, so the airfoils generate lift which supports each satellite vehicle and a distributed portion of the weight of the central hub. As the system rotates, centrifugal forces pull each satellite vehicle outwards, which keeps each tether taught and applies tension across each of the lifting surfaces, thereby alleviating the bending moment common to fixed-wing aircraft.

  • Patent number: 11365002
    Abstract: A tethered uni-rotor network of multiple tethered satellite vehicles; each having lifting airfoil surfaces, stabilizers, control surfaces, fuselages, and propulsion systems, operating in persistent state of rotation, driven by propulsion units on each satellite vehicle, where airfoils generate lift which supports aerial system. As system rotates, centrifugal forces pull satellite vehicles outwards, which keeps tethers taught. The tethers are attached to inboard portions of each lifting surface, which places their structural members under tension, thereby eliminating an adverse bending moment common to all traditional fixed-wing aircraft. Tethers provide large spatial separation eliminating rotor downwash field interactions, slowing system rotation rate, and permitting an ideal elliptic load distribution across wings.

  • Publication number: 20200361603
    Abstract: A tethered uni-rotor network of satellite vehicles combines fixed-wing and rotorcraft designs. A central hub with multiple tethers to satellite vehicles radiates outward in a hub-and-spoke arrangement. Satellites have lifting airfoil surfaces, stabilizers, control surfaces, fuselages, and propulsion systems. The system operates in a persistent state of rotation, driven by satellite propulsion units. As the satellite vehicles move through space, the airfoils generate lift which supports each satellite vehicle and the central hub. As the system rotates, centrifugal forces pull each satellite vehicle outwards, which keeps each tether taught.
