DEVICE TO ADJUST ANGLE OF BLADE TURNING IN TURBOMACHINE Russian patent published in 2007 - IPC F01D17/14 F01D9/02 

FIELD: mechanical engineering; turbomachines.

SUBSTANCE: proposed blade turning angle adjuster for turbomachine contains blades with radial turnable rods installed in housing bearings and connected by levers with adjusting ring enclosing housing from outside. Adjusting ring includes two semiround members whose ends are rigidly connected by bridges placed over longitudinal flanges of housing. Levers are installed for turning on ends of radial pins supported by semiround members and bridges of adjusting ring. Pins supported by semiround members are pointed radially outwards relative to semiround members, and pins supported by bridges are pointed radially inwards relative to bridges. Points of turning of levers on pins are arranged at one and the same distance from axis of turning of adjusting rings both for radial pins supported by semiround members and for radial pins supported by bridges of adjusting ring.

EFFECT: increased efficiency of turbomachine, reduced consumption of fuel owing to guaranteed equal angle of turning of adjustable blades.
