INTERMEDIATE HOUSING OF THE COMPRESSOR OF A BYPASS TURBOJET ENGINE Russian patent published in 2022 - IPC F02K3/75 F02C7/42 

FIELD: turbomachinery.

SUBSTANCE: invention relates to the field of turbomachinery, namely, to structural elements of the intermediate housings of turbojet engines. The intermediate housings of the compressor of a bypass turbojet engine contains a composite conical flow separator, power racks located between the outer and inner circuits, united by a composite conical flow separator consisting of fixed and movable sectors. The fixed sectors are made in one piece with the power racks, between which the movable sectors are located, the end walls of which are connected by rotary axes to the nearby fixed sectors. The rear walls of the movable sectors are kinematically connected to the drive of the guide vanes of the high-pressure compressor by means of rotary rods, levers and drive rings. The stator part of the high-pressure compressor is connected to the fixed sectors of the flow divider, while fingers are installed on the drive ring of the movable sectors. On the rear walls of the movable sectors of the separator, inclined slots are made with the possibility of contact with the corresponding pins of the drive ring of the movable sectors. The movable sectors and the front row of guide vanes of the high-pressure compressor are kinematically connected by means of one drive ring, which contains means for attaching fingers located on its front end, as well as means for connecting to the front row of guide vanes, the latter of which are installed from the side of the rear end of the drive ring.

EFFECT: increasing reliability and reducing the weight of the structure, by reducing the number of parts while maintaining synchronization of the rotation control of the movable sectors of the conical flow separator and the guide vanes of the high-pressure compressor.
