Abstract

Dans le procédé de commande de la turbomachine (2), un flux de gaz (28) alimente une chambre de combustion (10) en vue de faire tourner au moins un organe (14). Le procédé comprend les étapes de :- surveiller si se produit au moins un événement indiquant qu’une vitesse de l’organe (14) dépasse un seuil prédéterminé ; et- si l’événement se produit, dévier au moins une partie du flux (28) afin que cette partie du flux n’alimente pas la chambre de combustion.
