Abstract
L'invention concerne un propulseur à turbine à gaz comprenant un générateur de gaz dont la sortie est agencée pour entraîner une turbine de ventilateur disposée en aval du générateur de gaz, et un ventilateur monté pour tourner dans un conduit de dérivation en aval de la turbine de ventilateur. Ce ventilateur est agencé pour recevoir un flux combiné formé d'un flux d'air provenant du conduit de dérivation, et d'un flux provenant de la sortie de la turbine de ventilateur, et pour agir sur ce flux combiné comme fluide de travail. Application à la réduction du bruit des propulseurs d'avions.
