FIELD: mechanical engineering; gas turbines.
SUBSTANCE: device to prevent rotation of vane carrying sector of guide vane assembly in gas-turbine housing is essentially pin fitted in pair of holes. Holes are arranged on one straight line and are drilled in sector and in housing of gas turbine. According to one design version, pin is provided with lockring to keep it in holes. Lockring is installed under rim of sector of guide-vane assembly in groove of gas-turbine housing and occupies cross recess made in pin. According to other design version, pin is furnished with stop lug projecting relative to pin and engaging from one side with sector of guide-vane assembly and from other side, with housing of gas turbine.
EFFECT: prevention of turning of vane sector relative to gas-turbine housing, no violation of sealing in sector-to-sector joints.
