[Problem] The purpose of this invention is to provide the following: fluid machinery that takes in a fluid and converts same to a rotational flow so as to increase operating efficiency; and a power system, combustion device, and drying device using said fluid machinery. [Solution] This fluid machinery comprises the following: an intake section via which a fluid can be taken in; a rotational-flow conversion means that converts the direction of travel of said fluid to a rotational flow; a main body consisting of a vessel inside which the fluid rotates, said vessel being formed such that a fluid channel becomes gradually narrower in the direction in which the rotational flow travels; and an exit section from which the rotational flow exits. Said fluid machinery could be used as a combustion device or a drying device and could also be provided as a power system that has motor machinery that converts the rotational flow from the exit section into axial or vibrational kinetic energy.

PCT/EP2014/067894SENVION SESAMUELSEN, Olaf
The invention relates to a method for mounting internal tower fittings by introducing at least two separate supply modules (3, 4) into a wind turbine tower (1), wherein a separate supply module (3, 4) in each case structurally combines a segment of at least two system components (33, 34, 35, 36) of the wind turbine tower (1) and wherein an upper segment end (30, 40) is arranged on an upper edge (37, 47) of the supply module (3, 4) and a lower segment end (31, 41) is arranged on a lower edge (38, 48) of the supply module (3, 4), comprising the following steps: arranging the upper edge (37, 47) of a first separate supply module (3) on an upper end (17) of the wind turbine tower (1), connecting an upper segment end (30) of the first separate supply module (3) to a lower segment end (41) of a corresponding system component (33, 34, 35, 36) of a second separate supply module (4) and arranging the upper edge (47) of the second separate supply module (4) on the upper end (17) of the wind turbine tower (1). This results in a simplified mounting of the internal tower fittings and an increase in the safety of the installation personnel when mounting internal tower fittings.

F03D 1/06
PCT/NL2014/000028CORTEN HOLDING BVCORTEN, Gustave Paul
The invention concerns a blade for a wind turbine comprising an airfoil with a thickness of at least 20% and in particular at least 25% comprising a vortex generator pair between chordwise position 20%c and 70%c, said vortex generator pair comprising 2 not directly connected fins and a base which interconnects said fins and where said fins are placed under opposite angles of attack, characterized in that said fins are cambered by at least 1% in particular by at least 2% and more particularly by a least 3% of the fin chord. According to an embodiment of the invention the base of the vortex generator pair is W-shaped, the fins of a pair are designed to generate contrarotating vortices and the distance between the suction sides of the fins is approximately 150% of that between the pressure sides and the trailing part of the fins is rounded so that non- concentrated vortices are generated.

F03D 7/02
PCT/EP2014/067890SENVION SEWEISSFLOG, Oliver
The invention relates to a wind turbine comprising a wind rotor (13) for driving a generator (14) comprising a converter (15) for generating electric power, a controller (2) and an internal power supply unit (4), for which an auxiliaries transformer (3) is provided which is connected at the feed-in connection (31) thereof to the generator (14) and/or converter (15) via a power link (17) and supplies power to the internal power supply unit (4) via the low-voltage connection (41) thereof. A switching device (6) for the auxiliaries transformer (3) is provided which is designed to reverse a power flow through the auxiliaries transformer (3) in a reverse operating mode. For this, in the reverse operating mode the feed-in connection (31) of the auxiliaries transformer (3) is switched as output and is connected to a high-voltage consumer, and an output connection (32) of the auxiliaries transformer (3) is switched as input and is fed from the low-voltage connection (41) of the internal power supply unit (4). Therefore, by virtue of the power flow through the auxiliaries transformer being switched over to a reverse operating mode, said auxiliaries transformer can be used to generate the high-voltage level required on first operation, for which is was previously necessary for a separate booster transformer to be provided.
