FIELD: mechanical engineering.
SUBSTANCE: device of blade of an adjustable inlet guide vane comprises disc-shaped element and annular element aligned with said disc-shaped element to make a block therewith. Between the disc-shaped element and the annular element a set of blades of the adjustable inlet guide vanes is attached with possibility of rotation. Each blade of an adjustable inlet guide vane comprises the first rotary pin and the second rotary pin. First rotary pin is pivotally supported by the first bearing arranged in the disc-shaped element, and the second rotary pin is pivotally supported by the second bearing arranged in the annular element.
EFFECT: simplification of the design of the adjustable inlet guide vane blade and the corresponding activation system, as well as simplification and acceleration of their assembly.
