Abstract: A process for manufacturing a structural component made of composite material comprising a skin and at least one stiffening stringer applied rigidly and integrally to one face of the skin. The process comprises a) arranging, on a tool, a plurality of first layers of uncured or pre-cured composite material, forming the stringer and having a raised portion protruding from at least one flange; b) arranging, on the tool, a plurality of second layers of uncured or pre-cured composite material forming the skin; c) making a face of the skin and the flange of the stringer adhere to each other; d) applying a predetermined temperature and pressure on the assembly to compact the layers together, possibly curing the uncured material and rigidly joining the skin to the stringer; and e) performing a cutting operation on the free end side edge/s of the flange in a slanted direction.

Abstract: A method for estimating rotor torques of an aircraft capable of hovering and comprising a plurality of rotors, which are rotatable under the action of respective rotor torques; and an engine, which is operatively connected to the rotors to provide them with an engine torque. Each rotor comprises a hub and a plurality of blades articulated on the respective hub in such a way that respective collective pitch angles are adjustable. The method comprises the steps of i) calculating a symmetric component on the basis of the engine torque; ii) receiving a signal associated with collective pitch angles; iii) calculating an asymmetric component on the basis of a pitch angle difference between the collective pitch angles; and iv) calculating each rotor torque as the algebraic sum of the symmetric component and the respective asymmetric component.

Abstract: Display system for a vehicle operable by a user, the display system comprising: a graphics generator configured to acquire input safety critical data indicative of one or more operative parameters of the vehicle and generate, based on the input safety critical data, an intermediate video frame signal indicative of an intermediate video frame, wherein the intermediate video frame comprises a first frame region that is a visual representation of monitoring safety critical data and that includes encoding markers uniquely associated to the monitoring safety critical data, wherein the monitoring safety critical data and the input safety critical data reciprocally correspond in a condition of correct working of the graphics generator and do not reciprocally correspond in a condition of incorrect working of the graphics generator; a display control unit coupled to the graphics generator and configured to receive the intermediate video frame signal and determine the monitoring safety critical data based on the encoding markers; a display monitoring unit coupled to the display control unit and configured to receive both the input safety critical data and the monitoring safety critical data determined from the encoding markers, reciprocally compare the input safety critical data and the monitoring safety critical data and generate a command signal based on said comparison, the command signal being indicative of the correspondence, or of the lack of correspondence, between the input safety critical data and the monitoring safety critical data, wherein the display control unit is further configured to receive the command signal and, based on the command signal and the intermediate video frame and if the input safety critical data and the monitoring safety critical data correspond, generate a confirmed video frame signal indicative of a confirmed video frame that is configured to be displayed to the user and that is a visual representation of the monitoring safety critical data.

Abstract: The illumination optical device comprises a collimator, a light source, and an aperture. The collimator comprises a primary mirror, a secondary mirror, a tertiary mirror and a quaternary mirror mutually tilted so as to form a collimator optical path extending between the light source and the aperture and formed, in succession, by the light source, the quaternary mirror, the tertiary mirror, the secondary mirror, the primary mirror and the aperture. The light source is configured to emit light rays, along respective directions, which form a main beam propagating along directions intercepting the quaternary mirror so as to follow the collimator optical path; and a secondary beam propagating along directions not intercepting the quaternary mirror. The illumination optical device is characterised in that the collimator comprises a shielding structure configured to prevent illumination of the aperture by the secondary light beam.
