VANE ANGULAR POSITION CONTROL SYSTEM AND METHOD OF OPTIMISATION OF NAMED ANGULAR POSITION Russian patent published in 2014 - IPC F02C9/54 

FIELD: machine building.

SUBSTANCE: stator vane angular position control system, containing the devices for evaluation of preset angular position (VSV_CAL) of vanes depending on one of the speeds (N1, N2) and modulus of correction of the preset position (VSV_CAL), containing: devices for determination of angular position (VSV) of vanes; devices for measuring of fuel consumption (WFM) of the turbine jet; memory device, where the sequential angular positions (VSV_COU, VSV_REF) of vanes are related to values of fuel consumption (WFM_COU, WFM_REF) of the turbine jet measured in named angular positions (VSV_COU, VSV_REF); devices for determination of angle of correction (VSV_CORR) depending on the difference between the values of fuel consumption (WFM_COU, WFM_REF), measured between two consecutive angular positions (VSV_COU, VSV_REF) of the vanes. The invention also relates to the method of optimisation of the named current angular position.

EFFECT: optimisation of angular position of stator vanes of the turbine jet compressor.
