Abstract: A system may include a tether, a slip ring, a tether gimbal assembly, a drive mechanism, a control system. The tether may include a distal tether end coupled to an aerial vehicle, a proximate tether end, and at least one insulated electrical conductor coupled to the aerial vehicle. The slip ring may include a fixed portion and a rotatable portion, where the rotatable portion is coupled to the tether. The tether gimbal assembly may be rotatable about at least one axis and is coupled to the fixed portion of the slip ring. The drive mechanism may be coupled to the slip ring and configured to rotate the rotatable portion of the slip ring. And the control system may be configured to operate the drive mechanism to control twist in the tether.

Abstract: An airborne wind turbine system is provided including an aerial vehicle having a fuselage, an electrically conductive tether having a first end secured to the aerial vehicle and a second end secured to a rotatable drum positioned on a tower onto which the tether is wrapped when the aerial vehicle is reeled in, a perch extending from the tower, one or more perch booms attached to the perch panel and pivotably mounted to the tower, wherein when the aerial vehicle is secured to the perch, the aerial vehicle is positionable in a lowered parked position, and wherein the aerial vehicle is movable to a raised parked position caused by rotation of the one or more perch booms with respect to the tower.

Abstract: Wind energy systems, such as an Airborne Wind Turbine (“AWT”), may be used to facilitate conversion of kinetic energy to electrical energy. An AWT may include an aerial vehicle that flies in a path, such as a substantially circular path, to convert kinetic wind energy to electrical energy. The aerial vehicle may be coupled to a winch assembly via a tether. The winch assembly may include a winch drum and a drum door. The winch assembly may be configured such that the drum door may operate in two or more positions, such as an open position and a closed position, to reduce the likelihood of stability problems occurring at the aerial vehicle during winding or unwinding of the tether.

Abstract: A system may include an aerial vehicle, a perch platform configured to receive the aerial vehicle, and a ground station coupled to the aerial vehicle via a tether. The ground station may include a winch including a winch drum configured to move laterally and spin in a manner such that the tether is wound onto on the winch drum in a repeating pattern, possibly utilizing a fixed position levelwind. The system may additionally include a tower around which the winch and the perch platform can rotate about a vertical axis relative to the tower. The system may further utilize the tether forces on the levelwind to help move the perch platform around the vertical axis or be driven actively by a motor.
