In addition, the flying object 20 may be provided with a power storage device 230 that stores electric power generated by the rotating electrical machine unit. In addition, the flying object 20 may be provided with a detachably connected cartridge 260 that has a desired function.

The present turbine is intended for use in the field of renewable energy. The turbine comprises a rotor with a guide apparatus disposed thereon, said guide apparatus having inlets for a working fluid which are in the form of ducts that spiral around each other in helices and have nozzles situated along a tangent to the circle of rotation. The guide apparatus is configured in the form of adjacent ducts which are open along their entire length or along at least a significant portion of their length and are situated on second order surfaces of revolution or on portions of such surfaces, and in particular on convex-concave surfaces of the pseudosphere type with a cone in the pole of an axial cowl of the rotor. The result is in simplification of the structure and reduction in the turbine mass, the gyroscopic effect and the starting speed of the working fluid.

A system for electric power production from wind includes a glider having an airfoil, an on-board steering unit, a flight controller for controlling the steering unit, and a connection unit for a tether. The system further includes a ground station including a reel for the tether, a rotating electrical machine connected to the reel, and a ground station controller for controlling the reel and the rotating electrical machine. A master controller operates the system in at least first and second operation modes. In the first operation mode electric power is produced with the rotating electrical machine from rotation of the reel caused by reeling out the tether using a lift force generated upon exposure of the airfoil of the airborne glider to wind. In the second operation mode, the reel is driven by the rotating electrical machine, thereby reeling in the tether onto the reel.

The radial and axial magnetic levitation devices and the carbon brush set are mounted on the inner wall of the turbine shell, forcing the outer rotor rotating body to rotate freely in the turbine shell through the magnetic levitation bearings.

An emergency wind turbine system for an aircraft including an outer structure in which an opening is made includes an emergency wind turbine including: a mast; a turbine including a body mounted on the mast that rotates about an axis of rotation, and a single blade or two blades extending radially from the body between a blade root and a blade head; a locking device to lock rotation of the turbine body about the axis of rotation, when the emergency wind turbine moves between retracted and deployed positions, such that the blade root axis forms an acute locking angle with an orthogonal projection of the longitudinal axis of the mast over a plane substantially perpendicular to the axis of rotation of the turbine and in which the blade root axis extends, to reduce the volume swept by the turbine when it moves between the retracted and deployed positions.

The TRAVELING WAVE PROPELLER, PUMP AND GENERATOR APPARATUSES, METHODS AND SYSTEMS include force or forces applied to an arc-like flexible sheet-like material to create a deformed crenated strip fin with strained-deformations. The strained-deformations take on a sinusoid-like form that express the internal energy state of the flexible sheet-like material after it has been configured into a crenated strip fin. After being incorporated into a mechanism with couplings that prevent the crenated strip fin from returning to its un-strained state, the strained-deformations persist. Actuators may be used to sequentially rotate vertebrae attached to the fins causing the travel of sinusoid-like deformations along the fins. In a fluid medium, the traveling waves of sinusoidal deformations may exert force on the fluid causing the fluid to move and/or creating thrust. Arched blades affixed to the fins facilitate propulsion on hard surfaces such as ice.
