Abstract
A gas-turbine engine includes stator vanes () angularly variable about their longitudinal axes by actuating elements in order to control airflow supplied to downstream rotor blades (). The actuating elements are arranged in the most confined downstream stages of the compressors and/or turbines, with these stages being exposed to high temperatures, so that stable and efficient operation is ensured. The actuating elements () fixed to the inner or the outer casing () are made of a material expanding, contracting or deforming in dependence of the temperature and transmit the respective deformation to the swivellably borne stator vanes ().
