Abstract

La présente invention porte sur un moteur à turbine à gaz qui présente un rapport de pale de système de compression défini comme le rapport de la hauteur d'une pale de soufflante à la hauteur de la pale de compresseur la plus en aval dans la plage de 45 à 95. Cela résulte en un équilibre optimum entre des effets bénéfiques d'installation, des exigences de fonctionnement, de maintenance et un rendement du moteur lorsque le moteur à turbine à gaz est installé sur un aéronef.
