摘要： A locking device for an aircraft is described, comprising a body adapted to be fixed to a support surface, a first ring and a second ring rotatable the one with respect to the other with respect to a rotation axis between a first angular position and a second angular position. The first and second ring enclose an area for the landing of the aircraft and are contained within the body. The locking device also comprises a plurality of cables, which connect the first ring to the second ring. The locking device is positionable in an unlocking position, wherein the first and second ring are in the first angular position, the cables are spaced from said area; or in a locking position, wherein the first and second ring are in the second angular position and the cables occupy a region of the area, so as to cooperate in contact with the aircraft to constrain it with respect to the support surface.

摘要： The invention concerns a multimode feed for a reflector antenna of a monopulse tracking system. The feed comprises: a receiving element having an aperture, which receives an electromagnetic wave and generates, from the electromagnetic wave, a waveguide signal comprising a plurality of higher-order modes, as a function of an incidence angle of the electromagnetic wave on the aperture; and a waveguide structure, coupled to the receiving element, which generates, from the plurality of higher-order modes, a first error signal at a first output port and a second error signal at a second output port. The waveguide structure has: a first coupler that extracts, from the waveguide signal, a first higher-order mode and provides a first extracted signal; a second coupler that extracts, from the waveguide signal, a second higher-order mode and provides a second extracted signal; a third coupler that extracts, from the waveguide signal, a third higher-order mode and provides a third extracted signal; a fourth coupler that extracts, from the waveguide signal, a fourth higher-order mode and provides a fourth extracted signal; a first summing element that sums the first extracted signal and the second extracted signal, thereby generating the first error signal at the first output port; and a second summing element that sums the third extracted signal and the fourth extracted signal, thereby generating the second error signal at the second output port.

摘要： A roller unit for moving a slat of an aircraft wing is provided. The roller unit is adjustable in height and axial position to adjust a gap between an idle roller and a guide rail integral with the slat. The idle roller is carried by an eccentric pin having a stem portion with a threaded portion and an axially grooved end portion. A threaded annular element cooperates with the threaded portion of the stem portion to define a desired axial position of the idle roller. An anti-rotation annular element, coupled in an axially slidable manner with the grooved end portion of the stem portion, may be coupled with the threaded annular element to prevent rotation thereof on the threaded portion of the stem portion. The threaded annular element and the anti-rotation annular element are tightened together between a pair of nuts.

摘要： A method for the integration of continuous J shaped spars in extended panels of composite material in which J shaped spars are each arranged on a rectilinear support having at least one right triangle shaped portion, and the spars carried by the respective rectilinear supports are subsequently arranged on a stratified structure carried by a mould. A vacuum bag is created which covers the stratified structure, the rectilinear supports, and the J shaped spars. Holes are created in the vacuum bag at respective connection points made along each rectilinear support. A supporting structure provided with hooking and adjusting elements with the connection points adjusts the position of each hooking and adjusting element with respect to the supporting structure in order to position the rectilinear support in a direction parallel to the vertical so that the position of the end portion of the J shaped spar, with respect to the mould, corresponds to that foreseen by the design.
