An aircraft propulsion unit includes a turbojet engine, a lateral pylon connected to the fuselage of the aircraft, and a nacelle on the lateral pylon. The nacelle includes an upstream section having an air intake, a downstream section housing a reverse thrust device, and a middle section having two fan half-cowls surrounding a fan housing of the turbojet engine, and when said half-cowls are in a closed position defining an aerodynamic continuity between the upstream and downstream sections. The fan half-cowls include a maintenance half-cowl positioned under the horizontal median plane of the nacelle, able to move between the closed position and an open position allowing access to the turbojet engine for maintenance operations on the turbojet engine. The nacelle further includes at least one standby lock, designed to hold the maintenance half-cowl in a position intermediate to the closed and open positions.

An aircraft strut includes a primary structure which includes: a top stringer, a bottom stringer, at least one transverse frame which links the top stringer to the bottom stringer, a front end wall which links a front end of the top stringer to a front end of the bottom stringer, a rear end wall which links a rear end of the top stringer to a rear end of the bottom stringer, two lateral frames arranged on either side of the transverse frame, each lateral frame having a lattice form. An aircraft includes at least one strut described herein.

An aircraft is configured for thrust-borne lift in a vertical takeoff and landing flight mode and wing-borne lift in a forward flight mode. The aircraft includes an airframe having a first wing and a first payload station. A distributed propulsion system that is coupled to the airframe includes a plurality of propulsion assemblies configured to provide vertical thrust in the vertical takeoff and landing flight mode and forward thrust in the forward flight mode. A control system is operably associated with the distributed propulsion system and is operable to independently control each of the propulsion assemblies. A payload module is configured to be transported by the airframe from a pickup location to a delivery location. The payload module is magnetically coupled to the first payload station during transportation and, responsive to a command from the control system, is magnetically decoupled from the first payload station at the delivery location.

An engine support truss assembly for aircraft includes a mounting plate having a front side and a back side opposite the front side, a truss structure mechanically coupled to the front side of the mounting plate, and a backup structure mechanically coupled to the back side of the mounting plate. The truss structure includes a plurality of structural members each including precipitation-hardened stainless steel. The backup structure is configured to provide mechanical support to the truss structure.

An assembly having a pylon with an upper spar and four lateral scoops, a wing with a skin, longitudinal spars and fittings, and, for each lateral scoop, two fastening assemblies, wherein the skin and the fitting each have a first bore and wherein the upper spar and the lateral scoop each have a second bore, wherein each fastening assembly has a screw passing through the first and the second bores, a nut, two eccentric rings, threaded onto one another and onto the screw, and a system for stopping the eccentric rings rotating. The assembly makes it possible to dispense with the use of the spigots while also ensuring the reaction of the shear forces contained in the XY plane by the bolts on account of the reduced tolerances between the various bores, the external and internal surfaces of the eccentric rings and the plain zones of the screws.

An adapting part is designed to be held on a casing of a turbo-engine, partially covering the casing. The adapting part includes, in the extension of one of its axial ends, a first connector to engage with a first complementary connector associated with the casing to form a sliding connection. The adapting part also includes, at its other axial end, a second connector to be secured to a second complementary connector associated with the casing to form a rigid connection.

The gas turbine engine can have a casing, a rotor rotatable around a rotation axis relative the casing, the casing extending along and around the rotation axis, a first component mounted externally to the casing by a first mount, the first mount defining a torsion axis extending along a vertical radial orientation normal the rotation axis, the first component having a center of gravity located on a first side relative the torsion axis, a second component mounted externally to the casing on the second side, extending along the vertical radial orientation from a bottom portion to a top portion, a second mount structurally connecting the bottom portion to the casing, and a structure connecting the top portion to the first component on the second side relative the torsion axis.

An assembly having an articulation spindle mounted in a first sleeve inserted into a first arm of a clevis and in a second sleeve inserted into a second arm of said clevis said assembly comprising a blocking device. The blocking device comprising a screw with a first cylindrical portion which is screwed into an extension of the second sleeve and against which the second end of the articulation spindle can come to press, and a second portion, in the extension of the first portion, with a smaller cross section than said first cylindrical portion, a locking washer which is interposed between the second portion of the screw and the extension of the second sleeve in a locked position, and a longilinear element which passes through the screw and the second sleeve in a locked state.

Disclosed is a motor bracket of a multicopter flying robot. The motor bracket for the multicopter flying robot disclosed in the present invention includes: a body 110 receiving a rotary motor 500 therein which is used in the multicopter flying robot, a connection portion 120 which is formed on the outer surface of the body and receives two power supply lines 510 and 520 connected to a power terminal of the rotary motor 500, and a power supply member 300 which is pushed into the connection portion 120 and electrically contacts the at least two power supply lines 510 and 520. The connection portion 120 includes a spatial separation portion 122 which performs a function of forming separated spaces of which the number is the same as the number of the at least two power supply lines 510 and 520.

To reduce the overall mass of an engine assembly for aircraft, this assembly comprises a part of the fuselage of an aircraft, a turbomachine comprising an unfaired propeller, together with an annular row of unfaired after-guide vanes located aft of the propeller and rotationally fixed in relation to a longitudinal axis of the turbomachine, and a mounting pylon. At least part of the leading edge of the pylon is incorporated within the annular row between two after-guide vanes.
