TURBOMACHINE COMPRISING A MEANS OF SUSPENSION
The invention relates to a turbomachine (1) extending along an axis (X), comprising a high-pressure body with a high-pressure compressor (4) coupled in rotation to a high-pressure turbine (6), and a low-pressure body including a low-pressure compressor (3) coupled in rotation to a low-pressure turbine (7), an upstream casing (14) located upstream of the high-pressure compressor (4), and means of suspension (12, 13) for the turbomachine (1), intended for attaching the turbomachine (1) to an aircraft pylon (11).
Tilted propellers for enhanced distributed propulsion control authority
An aircraft comprises a fuselage, one or more support structures connected to the fuselage, one or more engines or motors disposed within or attached to the one or more support structures or the fuselage, and a distributed propulsion system. The distributed propulsion system comprising two or more propellers symmetrically distributed in an array along the one or more support structures with respect to a center of gravity of the aircraft and operably connected to the one or more engines or motors, wherein each propeller has a rotation direction within a tilted plane of rotation, and a summation of horizontal force vectors created by the tilted plane of rotation of all the propellers is substantially zero when all the propellers are creating a substantially equal thrust magnitude. Movement of the aircraft is controlled by selectively increasing or decreasing a thrust of at least one of the two or more propellers.
Turbojet of the unducted rotor type
A turbojet of the unducted rotor type and an aircraft including such a turbojet, the turbojet including a gas generator, a first unducted propeller connected to a shaft of the gas generator via first reduction gearing, and a second unducted propeller connected to a shaft of the gas generator via second reduction gearing, wherein the first propeller and the first reduction gearing are mounted at the front of the gas generator, and wherein the second propeller and the second reduction gearing are mounted at the rear of the gas generator.
Aerial imaging aircraft having attitude stability
An aerial imaging aircraft operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft includes an airframe having first and second wings with first and second pylons coupled therebetween. A two-dimensional distributed thrust array is coupled to the airframe. The thrust array includes a plurality of propulsion assemblies each operable for variable speed and omnidirectional thrust vectoring. A payload is coupled to the airframe and includes an aerial imaging module. A flight control system is operable to independently control the speed and thrust vector of each of the propulsion assemblies such that in an inclined flight attitude, the flight control system is operable to maintain the orientation of the aerial imaging module toward a target while translating the aircraft, changing aircraft altitude and/or circling the target.
ENGINE ATTACHMENT FOR AN ENGINE OF AN AIRCRAFT COMPRISING A YOKE, A CONNECTING ROD AND A WEARING PART BETWEEN THE YOKE AND THE CONNECTING ROD
An aircraft engine attachment including a beam fixed to a pylon and including a yoke with two walls, and a connecting rod with an articulation housed in the yoke, in which the connecting rod has a front flank and a rear flank which are facing inner faces of the walls. For each wall, a wearing part is disposed against the inner face of the wall and between the wall and the corresponding flank of the connecting rod. A Fixing arrangement ensures the fixing of the wearing part to the wall. Thus, the wearing parts prevent an excessive tilting of the connecting rod and the wearing of the connecting rod or of the yoke.
Link for aircraft component mounting
A gas turbine engine mount for an aircraft wing including a link body having a first joint, a second joint and a linking structure connecting the first joint to the second joint. The linking structure includes at least a flexing portion and an elastic portion. The flexing portion is configured to flex during a load outside of an expected load window.
Selectively thrusting propulsion units for aerial vehicles
Aerial vehicles may include propulsion units having motors with drive shafts that may be aligned at a variety of orientations, propellers with variable pitch blades, and common operators for aligning the drive shafts at one or more orientations and for varying the pitch angles of the blades. The common operators may include plate elements to which a propeller hub is rotatably joined, and which may be supported by one or more linear actuators that may extend or retract to vary both the orientations of the drive shafts and the pitch angles of the blades. Operating the motors and propellers at varying speeds, gimbal angles or pitch angles enables the motors to generate forces in any number of directions and at any magnitudes. Attributes of the propulsion units may be selected in order to shape or control the noise generated thereby.
Low pressure environmental control system with safe pylon transit
A disclosed gas turbine engine includes a fan section delivering air into a compressor section. An environmental control system includes a higher pressure tap at a higher pressure location in the compressor section, and a lower pressure tap at a lower pressure location. The lower pressure tap communicates to a first passage leading to a downstream outlet, and having a second passage leading into a compressor section of a turbocompressor. The higher pressure tap leads into a turbine section of the turbocompressor such that air in the higher pressure tap drives the turbine section to in turn drive the compressor section of the turbocompressor. A combined outlet of the compressor section and the turbine section of the turbocompressor intermixes and passes downstream to be delivered to an aircraft use.
Jet engine with a linking device
A jet engine with a linking device for linking the jet engine at an element of an aircraft optionally in a first mounting position and at least one second mounting position, and with at least one operating equipment appliance that has a first fluid area and a second fluid area. In the first mounting position, the first fluid area is assigned to a first functionality and the second fluid area is assigned to a second functionality. In the second mounting position, the fluid areas are assigned to the respectively other functionality. What is further described is an aircraft with at least one such jet engine.
JOINT ASSEMBLY HAVING SHIMMED BOSSES AND ASSOCIATED METHOD OF MAKING THE JOINT ASSEMBLY
An assembly that comprises a first part and a second part. The second part comprises a non-faying surface facing the base surface, a plurality of faying surfaces manifested at bosses that are shimmed if and as required, and a plurality of second through-holes. A width of each one of the plurality of bosses is equal to or greater than 2(r+T tan θ), where r is a maximum radial dimension of an outermost peripheral portion of a fastener in contact with the first part or the second part, T is the distance from the point of contact, between a fastener and the first part or the second part, and a faying surface of a corresponding boss, and θ is an angle between a central axis of the corresponding second through-hole and an outermost load vector initiating at the point of contact between the fastener and the first part or the second part.
