ABSTRACT:
A linkage system for the variable stator vanes of a gas turbine engine is augmented by control means operable as a function of compressor speed designed to match the aerodynamic requirements of the airflow through the compressor so as to define the rate of schedule change of the vanes over its angular movement by compensating for the inadequacies inherent in the capabilities of the linkage system.
