Abstract: A nacelle includes a thrust reverser having a cowl movable in translation and an ejection structure also movable in translation and forming with the cowl a moving assembly, the moving assembly configured to moved, alternately, into a closed position in which the ejection structure is inserted into a housing formed in the nacelle and the cowl closes an ejection opening in the nacelle, and an open position in which the cowl releases the ejection opening in the nacelle and the ejection structure is located in this ejection opening, the positioning of the ejection structure in the housing in the closed position making it possible, in particular, to make space in the ejection opening and to reduce the size of the thrust reverser.

Abstract: A deflector provided with a spoiler for a thrust reverser of an aircraft engine nacelle. The deflector, a lateral deflector or an orbital deflector, may be in an exhaust structure of a thrust reverser and comprises a deflector plate configured to act on an aerodynamic flow. The deflector plate has a concave upstream face and a convex downstream face, as well as an intake end and an exhaust end. The deflector is fitted with a spoiler rigidly connected to the exhaust end of the deflector plate and arranged transversely in relation to the deflector plate. The spoiler endowing the deflector with specific properties to act on the aerodynamic flow.

Abstract: A deflector for an ejection structure of a thrust reverser is disclosed including a deflector plate configured to act on an aerodynamic flow, the deflector plate having a concave upstream face, a convex downstream face, an inlet end, and an outlet end. The upstream face and the downstream face of the deflector plate have different curved profiles, the deflector has a particular profile giving it properties allowing it to act effectively on the aerodynamic flow so as to enhance the performance of the thrust reverser in which it is mounted.

Abstract: Examples of extended reality environment generation are provided. The techniques for extended reality environment generation may include receiving digital content and metadata associated with a physical environment and generating a digital layout of the physical environment by scaling the received digital content. Next, Global Positioning System (GPS) coordinates and functional coordinates are associated with placement locations in the digital layout. Further, a pre-defined placement of an asset is received in the digital layout and a set of GPS coordinates and a set of functional coordinates are identified for the asset placed in the digital layout. Next, the set of GPS coordinates and the set of functional coordinates are associated with metadata of the asset and the asset stored along with the metadata as a model linked with the digital layout. Further, an extended reality environment for the physical environment is generated with the assets by extracting the model.

Abstract: A grating for the formation of a reverse flow of a turbofan engine and comprising fins of a first type having a curved profile whose rounding is oriented aft and whose center of curvature is forward relative to the fin of the first type, fins of a second type having a curved profile whose rounding is oriented aft and whose center of curvature is forward relative to the fin of the second type. In this grating, each fin of one of the two types is inserted between two fins of the other type moving from forward to aft and the cord of the fins of the second type is smaller than the cord of the fins of the first type.

Abstract: The present disclosure relates to a method of simulation by computer of the airframe-engine interaction in an aircraft using angular segmentation of mixing planes. The method enables precise simulation of the airframe-engine aerodynamic interactions in shorter times thereby accelerating the development of the structure of the aircraft.

Abstract: An aircraft turbojet nacelle comprising blowing means intended to inject a tangential airflow (Ft) into the internal volume (V) of the nacelle, said blowing means being provided in a wall of the air intake of the nacelle in the supersonic area of said air intake. The invention also concerns a method for controlling separation in an aircraft nacelle, wherein a tangential airflow is injected (Ft) into the internal volume (V) of the nacelle in the locally supersonic area of the air intake so as to pull the main airflow (F) into the extension of the inner wall of the nacelle.

Abstract: An aircraft leading edge is extended by an aerodynamic surface providing an aerodynamic flow and where air discharges are arranged preventing separation of the aerodynamic flow. The air discharges are arranged in at least two rows essentially parallel to the leading edge and in an offset manner for at least two consecutive rows. At least one block is inserted between two walls that form the aerodynamic surface. The block includes, on the one hand, an outside surface extending the aerodynamic surface, a first inclined surface contacting the first wall forming the aerodynamic surface, and a second inclined surface contacting the second wall that forms the aerodynamic surface, and, on the other hand, projecting and/or hollow shapes that are made at the inclined surfaces and that are arranged in an alternating fashion from one surface to the next, allowing air to pass on both sides of the aerodynamic surface.
