A regulating system for a gas turbine, in particular an aircraft engine, has devices for blade-tip injection (ASC) for increasing the compressor stability, these devices being activated as needed. The regulating system is characterized in that it has devices for active clearance control (ACC), preferably in the high-pressure compressor, with which the radial clearance in the high-pressure compressor is kept in an optimum operating range, and the regulating system has a shared engine regulator (1) for both devices (ASC, ACC). The technical problems of the prior art are avoided through the present invention, and an improved regulating system for a gas turbine, in particular an aircraft engine, is made available for active stabilization of the compressor.
Système de régulation pour une turbine à gaz, en particulier un groupe motopropulseur, présentant, pour augmenter la stabilité du compresseur, des dispositifs d'injection à la pointe des aubes (ASC), qui sont activés en cas de besoin. Le système de régulation est caractérisé en ce qu'il comprend des dispositifs permettant la régulation active de l'intervalle (ACC), de préférence dans le compresseur haute pression, par lesquels l'intervalle radial dans le compresseur haute pression est maintenu dans une plage de fonctionnement optimale, et dans lequel le système de régulation comprend un régulateur de turbine (1) commun pour les deux dispositifs (ASC, ACC). L'invention permet d'éviter les problèmes techniques de l'état de la technique et procure un système de régulation amélioré pour une turbine à gaz, en particulier un groupe motopropulseur, permettant une stabilisation active du compresseur.
