Abstract

Moteur à turbine à gaz. La ou les chambres de combustion se terminent par un convergent 8 accélérant les gaz avant leur entrée dans le distributeur de la turbine, une partie tubulaire 9 à section constante, donc cylindrique ou annulaire, est disposée entre la sortie du convergent et l'entrée du distributeur 3, la longueur de cette partie dans le sens de l'écoulement étant au moins égale à la moitié de la hauteur de la veine comptée radialement. Application à tous moteurs, en particulier aux moteurs pour l'aéronautique.
