AIRCRAFT ENGINE COMPRESSOR AND DESIGN FOR FIXING POSITION OF ADJUSTABLE STATOR BLADE Russian patent published in 2023 - IPC F04D29/34 

FIELD: aircraft engineering.

SUBSTANCE: design (2) is proposed for fixing the position of an adjustable stator blade in an aircraft engine compressor, which holds the adjustable stator blade (3) in a given position during compressor operation, thereby improving the pneumatic characteristics of the compressor. The structure (2) for fixing the position of the adjustable stator blade contains an installation section (5), a limiting section (7) and a force transmission section (6), and the installation section (5) is located in the mounting hole (11) of the housing (1), the limiting section (7) is cone-shaped and thus fits into a conical hole (12) formed in the upper part of the shank of the adjustable stator blade (3), and the force transmission portion (6) is connected between the mounting portion (5) and the limiting portion (7) to transfer the load from the restrictive section (7) to the installation section (5).

EFFECT: improving fixation of the position of an adjustable stator blade.
