A method for determining the free-field thrust of a gas turbine engine using an enclosed gas turbine engine test facility without recourse to a outdoor gas turbine engine test facility. The method includes the steps of calculating the gas turbine engine intake momentum drag and cradle drag generated and compensating for these losses. In a further embodiment, the base drag is calculated and also compensated for.
Méthode permettant de déterminer la poussée en forme libre d'une turbine à gaz en utilisant un banc d'essai de turbine à gaz fermé sans utiliser de banc d'essai de turbine à gaz extérieur. La méthode comprend une étape de calcul de la traînée dynamique d'admission de la turbine à gaz et de la traînée de bâti générées et une étape de compensation de ces pertes. Dans une autre configuration, la traînée de base est calculée et également compensée.
