Abstract

Le procédé d'ajustement comprend : - une étape d'obtention (E20) d'une valeur d'un indicateur de performance de la turbomachine ; - une étape d'évaluation (E30) d'une valeur dite d'ajustement pour chacune des géométries variables déterminées conduisant à une amélioration de l'indicateur de performance par rapport à la valeur obtenue de cet indicateur ; - une étape d'ajustement (E70) de valeurs de consigne de la pluralité de géométries variables en utilisant lesdites valeurs d'ajustement évaluées ; et - une étape d'application (E80) des valeurs de consigne ajustées pour commander lesdites géométries variables ; une régulation de la turbomachine (E10) étant par ailleurs mise en œuvre en maintenant conforme à une loi de régulation nominale un paramètre représentatif d'une poussée de la turbomachine.
