A barge for recovery of a rocket launch vehicle is proposed, which can recover a launch vehicle from the sea onto the land in safety during launch vehicle recovering work. The barge can recover the launch vehicle in safety by effectively preventing a slope of the structure which supports the launch vehicle.

An automatic displacement device for use in a carrier includes at least one weight mount, at least one actuator, and at least one stability regulator. The weight mount can hold at least one heavy object accommodated in the carrier' body. The actuator is coupled to the weight mount. The stability regulator is electrically communicated to the actuator and includes a sensor and a controller. The sensor can measure a state associated with an angle of the carrier's body and output a signal representative of the state. The controller calculates a tilt of the carrier according to the signal outputted from the sensor and is capable of commanding the actuator to move the weight mount in view of the tilt to perform a compensation on the carrier.

A buoyant structure having a hull, a main deck, an upper cylindrical side section extending downwardly from the main deck, an upper frustoconical side section, a cylindrical neck, a lower ellipsoidal section that extends from the cylindrical neck, an ellipsoidal keel and a fin-shaped appendage secured to a lower and an outer portion of the exterior of the ellipsoid keel. The upper frustoconical side section located below the upper cylindrical side section and maintained to be above a water line for a transport depth and partially below the water line for an operational depth of the buoyant structure.

The Lopsided Payload Carriage Gimbal in al its embodiments allow Aerial Vehicles and Water-borne vehicles to carry payloads far from the vehicle Geometric Center without significant travel of the vehicle's overall Center of Gravity. Large travel of the CG limits vehicle's performance or renders it inoperable. The embodiments rely on the interaction of the payload and the counter balancing weight through the payload link 18, balancing link 10 main link 14 and battery pylon 8 to substantially reduce the torque generated by the payload in a lopsided position. The embodiments also allow the vehicle carrying the payload to change thrust direction agilely. Finally, the embodiment acts as a mechanical stabilization device for the payload as well. This invention is adaptable to all forms of hover-capable aerial vehicles as well as water-borne vehicles.

The nacelle of a horizontal axis wind turbine is fixedly mounted on a tower, and the tower is mounted off-center with respect to a ring around which it is rotatable. The tower is a tripod. Two legs of the tripod are of fixed length and lie in a plane perpendicular to the axis of rotation of the turbine blades. The third leg of the tripod is of adjustable length and is aligned with the axis of rotation of the turbine blades. The third leg thus may be controlled to adjust for pitching of the base and other purposes. Multiple turbines, spaced apart laterally, may be mounted on a platform in a fixed orientation, with the platform rotatably mounted off-center relative to a base.
