    Abstract: The invention relates to a method and device for production of a three-dimensional article from a material, by means of layered application. According to the invention, a dropwise application is carried out, whereby drops of reaction components are ejected by a nozzle arrangement (3) and applied to a base reaction component (2), arranged on a substrate (1). The material for the three-dimensional article is formed in layers, with reaction of the base reaction component (2) with reaction components on contact, whereby the material is formed on a reaction of the base reaction component with one of the reaction components to give a material with one material property and on another reaction of the base reaction component with another of the reaction components to give a material with another material property. On production of the three-dimensional article, an article section is produced in which a gradual transition between the one material property and the other material property is generated.

    Abstract: The wings of a rotary wing aircraft comprise, for example, four wing bladesorming two pairs of wing blades whereby the blades of a pair are located diametrically opposite each other. The blades of a pair are connected to each other by a spar extending from wing blade to wing blade. The spar is operatively secured to the rotor head. Each spar has between the rotor head and the respective wing blade a zone with a torsion yieldability larger than in the spar outside said zone. A beam stiff against bending, bridges the zone, referred to as a torque soft zone, from the wing blade toward the rotor head except for a small flexible section between the rotor head and the radially inner end of the beam. The flexible section permits the blade flapping movements and the blade lead-lag movements.

    Abstract: The present four-blade rotor structure comprises two pairs of rotor blades.iametrically opposite each other located blades form a pair and the blades of a pair are connected to each other by coupling belts which are tension resistant and torsionally yielding. One coupling belt extends substantially horizontally whereas the other extends substantially vertically. The coupling belts are centered in the rotor head by respective centering bodies. The centering bodies are connected to their respective belt by bearing elements capable of taking up pressure loads while simultaneously permitting a blade angle adjustment. In a modification the bearings may be slide bearings.
