COMPRESSOR INTERMEDIATE HOUSING OF TURBOJET Russian patent published in 2020 - IPC F02K3/75 F02C7/42 

FIELD: machine building.

SUBSTANCE: invention relates to the field of turbomachinery, namely to the elements of the construction of the intermediate casings of gas turbine engines. Disclosed is an intermediate housing of turbomachine with a flow divider, comprising power posts 1, arranged between external 2 and internal 3 circuits, combined with a composite conical flow divider, consisting of fixed 4 and movable 5 sectors. Fixed sectors 4 are made integral with power posts 1, between which there are moving sectors 5, end walls 6 of which are connected by rotary axles 7 with nearby fixed sectors 4, and rear walls 8 of movable sectors 5 are kinematically connected to drive. According to the invention, the outer diameter of internal circuit 3 is formed by stator part 9 of the high-pressure compressor with adjustable guiding devices 10, also stator part 9 of the compressor is connected to fixed sectors 4 of the flow divider, besides, the drive of guide vanes 10 of the compressor and movable sectors 5 of the separator is made common.

EFFECT: technical result achieved when using the claimed invention is to increase reliability and reduce weight of the structure by reducing the number of parts, as well as simplifying the engine control system.
