    • A wind turbine blade having a longitudinal direction with a root end and a tip end as well as a chord extending in a transverse direction between a leading edge and a trailing edge is described. The blade comprises a flow control surface with a suction side and a pressure side. A number of boundary layer control means is formed in the flow control surface. The boundary layer control means include a channel submerged in the flow control surface with a first end facing towards the leading edge and a second end facing towards the trailing edge of the blade. The channel comprises: a bottom surface extending from the first end to the second end, a first sidewall extending between the flow control surface and the bottom surface and extending between the first end and the second end, the first sidewall forming a first sidewall edge between the first side wall and the flow control surface, and a second sidewall extending between the flow control surface and the bottom surface and extending between the first end and the second end, the second sidewall forming a second sidewall edge between the second side wall and the flow control surface. The channel at the first end comprises a first flow accelerating channel zone adapted for accelerating a flow, and at the second end comprises a second channel zone, where the first sidewall and the second sidewall are diverging towards the trailing edge of the blade.

    • The invention relates to laser cutting, using multiple laser beams directed to a processing region. At least one first laser beam (2) is coupled into the work piece (1 ) material to generate a melt (5) and to form a keyhole (3). At least one second beam (6) is guided onto selected surface regions (7) of the melt (5). The laser energy is provided to the processing region as individual beams that may be conditioned independently. The invention has the advantage that arbitrary energy distributions can be arranged in the processing region as determined according to the requirements of the laser cutting process, rather than being limited by an inappropriate beam shape of a single high power laser beam.

    • The invention relates to a method for producing a rotary hydrodynamic thrust bearing and to a rotary hydrodynamic thrust bearing. The thrust bearing comprises a first bearing part having a first bearing face and a second bearing face facing the first bearing face and being formed of pad bearing faces (5) of at least two pads (2), said pads being supported on a common base (4) by means of supporting means (3) allowing the pads to tilt slightly when subjected to an axial tilting load, one of said first and second bearing parts being rotatable relative to the other bearing part about a rotation axis in a rotational direction. The method comprises the steps of (a) providing a blank (100) for the second bearing part being essentially identical to the second bearing part apart from machining allowances on upper faces (105) of the pads (102) to be machined for forming the pad bearing faces (115), (b) using preloading means (116), simultaneously providing a predetermined substantially identical preload to each of the pads (102) of the second bearing part (101), thereby elastically deforming the pad (102) and/or the corresponding supporting means (103) so as to tilt the pad with respect to a resting position, (c) machining the upper faces of all pads to a common plane with the preload applied to all pads so as to obtain the pad bearing face of each of the pads, and (d) removing the preload from each pad so as to allow each pad to return to its resting position in which me bearing face thereof has a predetermined shoulder height (S n ).
