Abstract: A lifting surface comprising a movable discontinuity located in the surface of the lifting surface. The movable discontinuity is movable between an active position in which the movable discontinuity acts as vortex generator, and a passive position in which the movable discontinuity is integrated into the surface of the lifting surface without acting as vortex generator. The lifting surface may be in an elevator, the elevator being rotatable around a hinge line with respect to the rest of the lifting surface. A bar is rigidly joined to the elevator. The bar, the elevator and the movable discontinuity are configured such that when the elevator rotates with respect to the rest of the lifting surface, the bar moves the movable discontinuity that departs from the surface of the lifting surface, acting as a vortex generator.

Abstract: A computer-aided method suitable for assisting in the design of an object zone, such as a CROR engine of an aircraft subjected to high vorticity and/or low static pressure fields when moving inside a flow field, by providing suitable seed points for constructing vortex core lines in a fluid data model of the environment of the object zone and a system based on the method. The method steps are: a) Obtaining a dataset containing all the cells or points satisfying one of the conditions of four Region-based vortex detection criteria (the Q-criterion, the Kinematic vorticity number, the Δ-criterion, the λ2-criterion); b) Obtaining a new dataset containing all the cells or points of the previous dataset satisfying one of the conditions mentioned in step a) not selected previously; c) Repeating the step b) until all the conditions mentioned in step a) have been selected in step b).

Abstract: An optical fiber connection device comprising a prism, first and second connection elements, inner and outer ferrules and an elastic element. The prism has an inner conduit ending in a first bore configured to receive an input optical fiber, and in a second bore configured to receive the first connection element, which, in turn, is configured to receive the second connection element. This second connection element is also configured to receive an output optical fiber. The conduit comprises two sections forming a ramp to lead the input optical fiber towards the fibers connection. The first connection element has an inner box, and the second connection element has an outer protrusion to provide a unique connecting position. The inner and outer ferrules, and the elastic element are retained in the second connection element.

Abstract: An aircraft comprising a fuselage extending along a longitudinal axis between a fore section and an aft section, wings mounted to the fuselage, a tail unit mounted to the aft section of the fuselage, and a first propulsion unit and a second propulsion unit both mounted to the aft section of the fuselage in such a way that a first axis of rotation of the first propulsion unit and a second axis of rotation of the second propulsion unit both extend in a vertical center plane spanned by the longitudinal axis and a yaw axis. The provided centerline mounted double-engine aircraft allows for a simple manufacture, maintenance and retrofit of the engines, in that the first propulsion unit and/or the second propulsion unit are arranged outside the fuselage.
