FIELD: engine devices and pumps.
SUBSTANCE: axial flow compressor stage guide vanes contains a body made with a longitudinal connector, inner semirings and rotary blades, which are installed by their inner journals into half rings. Reciprocal fixation of the semirings is performed by means of a stud with a spring-loaded pin mounted on it, which can be fixed in a recessed position, and a slot with a hole for the pin.
EFFECT: invention makes it possible to rigidly connect the semirings of the guide vanes of any stage of the stator of a gas turbine engine compressor having a longitudinal connector, to simplify the assembly and disassembly of the guide apparatus and to improve the processability of the compressor casing.
