Variable-Adjustable Stator Blade Angle Position Control System of a Turbocharger Compressor and Angle Position Optimization Process of a Turbocharger Compressor Stator Blade Current

摘要

Variable-adjusting stator blade angular position control system of a turbomotor compressor and Process of optimizing the angular position of a turbomotor compressor stator blade current. a stator blade angular position control system comprising means (20) for calculating a blade reference angular position (vsv ~ cal ~) as a function of one of the speeds (n1, n2) and a module (1) reference position correction (vsv ~ cal ~) comprising: - means (2) for determining the angular position of the blades (vsv); - means (3) for measuring turbo motor fuel flow (wfm); - a memory (4) in which successive angular positions of the blades (vsv ~ cou ~, vsv ~ ref ~) are associated with the turbomotor fuel flow (wfm ~ cou ~, wfm ~ ref ~) measured at said angular positions ( vsv ~ cou ~, vsv ~ ref ~); and - means (5) for determining a correction angle (vsv ~ corr ~) as a function of the difference between the fuel flow rates (wfm ~ cou ~, wfm ~ ref ~) measured between two successive angular blade positions (vsv ~ cou ~, vsv ~ ref ~). The invention also relates to a method of optimizing said current angular position.
