An ocean water power-generator for generation of renewable energy.

An airship dynamic adaptive harness is provided to stabilize airships and particularly a tethered aerostat in high winds and atmospheric changes. A novel adaptive device accommodates the supply of a lift gas and simultaneously controls opposing cables in a tethered harness with a cascade control system that provides an immediate and particularly the dynamic control of roll, yaw and particularly the pitch of the aerostat in response to real time environmental flight conditions and impart stability to the airship in high winds using a stability zone geometric suspension control system and enhance the duration of in flight missions. A lifting gas replenishment system and particularly a ground based lifting gas replenishment system adds long duration deployment to the dynamic adaptability to high wind conditions for long term deployment.

A tethered unmanned aerial system (UAS) is described, wherein the flight of one or more UASs may be used in connection with a water and light display.

Embodiments disclosed herein enable routine autonomous execution of at least some major phases of aerostat operation in response to commands from human or automated external operators, a built-in decision-making capacity, or both. Various embodiments combine one or more actively controlled tethers, aerodynamic aerostat control surfaces, mechanical assistive devices (e.g., jointed arms attached to a ground station), and/or active propulsors attached to the aerostat to govern aerostat behavior during launch, flight, and landing phases of operation. Some embodiments enable automatic autonomous performance of all phases of routine post-commissioning aerostat operation, including launch, flight, and landing, without any routine need for availability of a human crew.

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.

An unmanned aerial vehicle system includes an unmanned aerial vehicle, a tether assembly selectively coupled to the unmanned aerial vehicle, a processor, and a memory. The memory contains instructions thereon, which, when executed by the processor, cause the system to disconnect the tether assembly from the unmanned aerial vehicle.

A flying machine includes: a flying machine body that includes a rotor blade; a protective member that forms a frame shape inside which the rotor blade is disposed, that is rotatably fixed to both end portions of the flying machine body, and that is pipe shaped; and a connecting wire that passes through an inner portion of the protective member to connect the flying machine body and an external device together.

Apparatuses for securing drones during transport and methods of use are disclosed herein. An example apparatus includes a structural panel of a vehicle having a compartment configured to receive and retain a drone, a retractable cover member configured to at least partially cover the compartment to create an enclosure around the drone, and a drone securement assembly that retains the drone within the enclosure so as to prevent the drone from displacement during vehicle operation.

An aerial vehicle including a fuselage, a main wing attached to the fuselage, a support structure extending upwardly from the fuselage and having a front surface facing the main wing, an overhang positioned on a top of the support structure and extending towards the main wing, one or more rotating actuators positioned on the overhang, a rear elevator attached to the one or more rotating actuators that are configured to move the rear elevator from a flying mode position where a leading edge of the rear elevator faces the main wing to a hover mode position where the major surfaces of the rear elevator faces the main wing, and wherein the major surfaces of the rear elevator remain in front of the front surface of the support structure when the rear elevator is moved from the flying mode position to the hover mode position.

A reactive tether spool comprises a drum, a signal cable, a drum actuator, a tension sensor, and a controller. The signal cable transports power and a control signal to a UAV. A controller receives a tension measurement from the tension sensor and controls the drum actuator to maintain a determined tension on the signal cable while performing at least one of the following: dispensing the signal cable; holding the signal cable steady; and collecting the signal cable.
