ENGINE WITH ROTATING DETONATION COMBUSTION SYSTEM
A Brayton cycle engine including a longitudinal wall extended along a lengthwise direction. The longitudinal wall defines a gas flowpath of the engine. An inner wall assembly is extended from the longitudinal wall into the gas flowpath. The inner wall assembly defines a detonation combustion region in the gas flowpath upstream of the inner wall assembly.
Turbofan comprising a system comprising a screen for closing off the bypass duct
A turbofan has a nacelle delimiting a duct for a bypass flow and comprises a fixed structure comprising a guide vane support with guide vanes, a mobile cowl able to move in translation between an advanced position and a retracted position, arms, each one being mobile in rotation between a stowed position and a deployed position and comprising a distal end and a proximal end, a flexible screen, of which an exterior edge is attached to the guide vane support rearward of the guide vanes, and wherein the distal end of each arm is fixed along the interior edge, actuators to cause the mobile cowl to move, and an operating system which moves each arm. Replacing the reversal doors and their drive mechanisms with the flexible screen and the set of rotationally-mobile arms allows a reduction in weight.
Two-dimensional supersonic nozzle thrust vectoring using staggered ramps
A system and method for vectoring the thrust of a supersonic, air-breathing engine. A thrust vectoring mechanism uses two asymmetrically staggered ramps; one placed at the throat, the other positioned at the exit lip of the nozzle of the engine to re-direct exhaust flow off-axis with the nozzle.
Engine with rotating detonation combustion system
A Brayton cycle engine including a longitudinal wall extended along a lengthwise direction. The longitudinal wall defines a gas flowpath of the engine. An inner wall assembly is extended from the longitudinal wall into the gas flowpath. The inner wall assembly defines a detonation combustion region in the gas flowpath upstream of the inner wall assembly.
THRUST REVERSER FOR TURBOFAN PROPULSION SYSTEM OF AN AIRCRAFT AND THRUST REVERSAL METHOD
A thrust reverser system for a turbofan propulsion system of an aircraft includes a fixed structure and a translating structure configured to internally define a sequential flow path for air. The translating structure is slidable along an axial direction between a stowed position in which the translating structure is connected to the fixed structure, and an opening position in which the translating structure is spaced apart from the fixed structure in the axial direction to define a circumferential opening for outflow of air to external environment. An iris mechanism has a plurality of blades jointly movable between a rest configuration in which the blades jointly define a passage for air, and a deployed configuration in which the blades at least partially occlude a bypass duct of the turbofan propulsion system.
AIRCRAFT TURBINE ENGINE
The invention concerns an aircraft turbine engine (1), comprising a gas generator comprising at least one annular gas flow duct (2), the duct (2) being defined by two annular housings, respectively an external housing (3b) and an internal housing (3a), extending one around the other and connected together by at least one tubular arm (5) for the passage of a lubricating oil line (7). According to the invention, the line (7) comprises a first fixed section (14) secured to the external housing (3b), a second fixed section (16) secured to a piece of equipment (4) of the turbomachine capable of moving or vibrating during operation relative to the housings (3a, 3b). and an intermediate section (18) connecting the first and second sections (14, 16), this intermediate section (18) having a generally elongate shape and comprising longitudinal ends engaged and capable of swiveling and/or sliding in ends of the first and second sections (14, 16).
BLOWER
A blower includes: a base; a case disposed above the base and provided with an inlet and an outlet; a fan disposed inside the case and forming a flow of air from the inlet to the outlet; a rotating plate disposed below the case and rotatably disposed on the base, in which the base includes a rotating shaft housing that is a cylindrical shape and protrudes toward the rotating plate, and the rotating plate includes a shaft body that protrudes downward from the center and is inserted into a shaft insertion groove of the rotation shaft housing and at least one bearing that is disposed on a lower surface of the rotating plate, is radially spaced from the shaft body, and is in contact with an upper surface of the base.
BLOWER
A blower includes: a base; a case disposed above the base and provided with an inlet and an outlet; a rotating plate disposed below the case and rotatably disposed on the base; an electric wire whose part is exposed to an outside of the base and the other part extends upwards of the rotating plate through the base; and an electric wire holder including an electric wire holder that is fixedly disposed on the rotating plate and fixes one side of the electric wire extending towards of the rotating plate from an inside of the base, in which the base includes an electric wire fixing protrusion that fixes the other side of the electric wire extending from an outside to an inner space of the base and an electric wire guide rib that fixes a partial arrangement of the electric wires whose arrangement is changed in an inner space of the base according to a movement of the rotating plate.
SYSTEM AND METHOD FOR RECONFIGURING A BLEED SYSTEM
A system includes a bleed system configured to direct a bleed flow from a compressor section to an exhaust section of a gas turbine engine. The bleed system includes a first bleed conduit section configured to couple to the compressor section, a second bleed conduit section configured to couple to the exhaust section, and a first rotatable joint coupling together adjacent conduits of the first and second bleed conduit sections. The second bleed conduit section has components configured to rotate between a plurality of configurations relative to the first bleed conduit section and the compressor section via the first rotatable joint. The plurality of orientations corresponds to a plurality of exhaust outlet orientations of the exhaust section, and the components of the second bleed conduit section are the same in each orientation.
Belly band seal with anti-rotation structure
A belly band seal for use in a multi-stage turbomachine having plural rotor disks includes a seal strip positionable in a space between a pair of arms defined by opposing portions of adjoining rotors. The seal strip includes opposite edges for locating in respective slots in end faces of said pair of arms. The belly band seal further includes an anti-rotation structure disposed on a radially inner surface of the seal strip. The anti-rotation structure is configured as a cantilever having a pivoted end fixed to the radially inner surface and a free end comprising a radially inwardly extending engagement member for removably positioning in a radial recess in one of the arms. The cantilever is configured so as to urge the engagement member toward the radial recess by spring action. The radial recess is configured to constrain a tangential movement of the engagement member upon being positioned therein.
