FIELD: mechanical engineering, possible use for turning guiding compressor blades, and also nozzle blades of turbine used in aviation engineering for decreasing turning force, increasing precision of installation of blades in the stream.
SUBSTANCE: device for turning guiding blades of compressor and also nozzle blades of turbine includes body with blades, adjusting ring, positioned concentrically to the body and connected to each lever of blade via a joint, allowing radial movement, and has additional ring positioned concentrically to adjusting ring and connected to it by cylindrical joint, which via joints, allowing radial movements, is connected to at least three additional levers held on blade pins and located diametrically oppositely to main levers relatively to pin.
EFFECT: increased efficiency of compressor, turbine and engine.
