A method for controlling the angle of adjustment variable guide vanes

摘要

A method for control and / or control of the angle of adjustment of adjustable guide vanes of a grid of a compressor, in particular of a high-pressure compressor, a gas turbine, in particular of an aircraft engine, wherein the adjustment angle as a function of an aerodynamic speed of rotation of the compressor according to a first adjusting law is determined, characterized in that the adjustment angle, in addition, in a function of a mechanical rotational speed of the compressor is determined in such a way that, when the mechanical rotational speed of the compressor a certain proportion of a maximum permissible mechanical rotational speed has been reached, the adjustment angle as a function of a second adjusting law (13) is determined, wherein the second adjusting law (13) has a larger displacement angle, namely, a larger opening angle, is generated as the first adjusting law (12).
