Abstract

A method of controlling a gas turbine engine (10) which has a booster compressor (13), a core compressor, combustion equipment, a core turbine, and a low-pressure turbine (18). The low-pressure turbine also drives an external load having a defined speed characteristic. The booster compressor (13) has one or more rows of variable stator vanes. The method includes: scheduling variation in the angle of the variable stator vanes as a function of the speed of the booster compressor such that the vanes open as the booster compressor speed increases; measuring or setting one or more operational parameters which are determinative of the temperature at entry to the core turbine; and biasing the scheduling of the angle variation of the variable stator vanes as a function of the operational parameter(s) to reduce variation in temperature at entry to the core turbine
