Claims (3)

  1. Fonctionnement d'un groupe motopropulseur avec au moins un compresseur, une chambre de combustion et au moins une turbine, caractérisé en ce qu'après l'arrêt du groupe motopropulseur, un rotor de la ou de chaque turbine est entraîné pour une durée déterminée afin de provoquer par là-même un refroidissement uniforme du rotor, le rotor de la turbine respective étant entraîné à une vitesse de rotation comprise entre 0,1 et 10 tr/min.
  2. Fonctionnement selon la revendication 1,
    caractérisé en ce qu'après l'arrêt du groupe motopropulseur, le rotor de la turbine respective est entraîné à une vitesse de rotation comprise entre 0,2 et 5 tr/min.
  3. Fonctionnement selon la revendication 1 ou 2, caractérisé en ce qu'après l'arrêt, une circulation d'huile est provoquée ou établie afin d'empêcher ainsi un cokage de l'huile après l'arrêt du groupe motopropulseur.
