Offshore airborne wind turbine systems with an aerial vehicle connected to an undersea anchor via a tether are disclosed. A floating landing platform may be coupled to the tether and be dragged along the surface of the water along with the tether. The landing platform may be designed such that the tether can freely pass through the platform, allowing the aerial vehicle to ascend, descend, move laterally, and in crosswind flight, without creating a significant tension load on landing platform. The landing platform may also include a tether drive mechanism that can actively move the tether through the platform, thus changing the platform's location along the length of the tether.

The present disclosure relates to an aerial vehicle with a horizontal tailplane disposed along a bottom edge of a vertical tailfin. Namely, the aerial vehicle includes an empennage attached to the fuselage via a tail boom and a tail coupling. The empennage includes a vertical tailfin that extends below the tail coupling. The empennage also includes a tube arranged along a leading edge of the vertical tailfin and below the tail coupling of the aerial vehicle. The empennage additionally includes one or more rotating actuators and a horizontal tailplane. The horizontal tailplane is coupled to the tail via the tube and includes a continuous leading edge and a cutout. The one or more rotating actuators are configured rotate the horizontal tailplane about an axis of the tube. At least a portion of the vertical tailfin is configured to pass through the cutout.

Systems and methods for operating aerial vehicles in water-based locations. The systems and methods include a plurality of landing stations. Each landing station of the plurality of landing stations is coupled to at least one of: another landing station or an underwater mooring point. The systems and methods also include an aerial vehicle coupled to a tether mooring point by a tether. The aerial vehicle is configured to land on at least one landing station of the plurality of landing stations.

A ram air turbine rotor comprises at least one intra-flow path shroud structure coupled between rotor blades, along a radial position between a support disc and an outer rim. The shroud structure includes shroud sectors each coupled between a respective pair of blades. The sectors each include a first edge adjacent to leading edges of the respective pair of blades, the first edge including a first curved segment, and a second edge adjacent to trailing edges of the respective pair of blades, the second edge including a second curved segment. The curved segments are each partially defined by a respective ellipse having a semi-major axis and a semi-minor axis. The semi-major axis is a portion of a spanwise distance between the respective pair of blades. The semi-minor axis is a portion of an axial distance between the leading edge of one blade and the trailing edge of an adjacent blade.

A portable system for converting wind energy into electrical energy is disclosed. The disclosed system may include a frame hosting one or more conversion modules, arranged as desired. A given conversion module may include one or more wind energy conversion devices (WECDs), arranged as desired. The conversion modules may be electrically connected, directly or indirectly, with one or more downstream electrical energy storage elements (e.g., such as a battery or other capacitive element, optionally native to a host platform). In this manner, the disclosed system may be configured for use in storing and/or supplying electric power for downstream consumption by a host platform or otherwise. In a more general sense, the disclosed system may be utilized, for example, for micro-generation of renewable electrical energy from wind.

A helicopter includes a propulsion system, gimbal assembly, and a controller. The propulsion system includes a first and second rotor assembly, wherein the first rotor assembly comprises a first motor coupled to a first rotor, the first rotor comprising a plurality of first fixed-pitch blades and the second rotor assembly comprises a second motor coupled to a second rotor, the second rotor comprising a plurality of second fixed-pitch blades. The second rotor is coaxial to the first rotor and is configured to be counter-rotating to the first rotor. The controller is communicably coupled to the gimbal assembly and is configured to provide instructions to at least one of the first or second gimbal motors in order to orient the plurality of first and second fixed-pitch blades into a position that permits wind to rotate the first and second fixed-pitch blades and thereby charge the power source.

System and methods for controlling the oscillation of floating ground stations in aerial wind turbine systems are disclosed. Thrusters on the ground station or on one or more aerial vehicles associated with the ground station apply a compensatory force to the oscillating ground station to reduce and/or substantially eliminate wave-induced oscillations. Submerged thrusters may also rotate the ground station to a preferred alignment direction with the waves. Additionally, control systems use environmental and/or positional sensor data to develop a predictive force profile that maps desired compensatory force magnitude versus time. The control systems use that predictive force profile to direct the thrusters to apply a varying compensatory force over time.
