Title (EN) PROPULSION ASSEMBLY HAVING UNCOUPLABLE HOUSING PORTIONS
(FR) ENSEMBLE PROPULSIF MUNI DE PARTIES DE CARTER DECOUPLABLES
Abstract:
(EN) The invention relates to a propulsion assembly, including a turbine engine configured to be attached to an aircraft by means of a suspension, of which some housing portions may be uncoupled to attenuate some bending modes of the turbine engine in the event of damage, the propulsion assembly comprising at least one first and one second housing portion (33a, 22) extending axially one after the other, one of said housing portions overhanging said suspension, in which the first housing portion (33a) has a first attachment portion (41) rigidly connected to the body (43) of the first housing portion (33a) and a second attachment portion (42) more flexibly connected to the body (43) of the first housing portion (33a), and in which the second housing portion (22) is permanently attached to the second attachment portion (42) of the first housing portion (33a) and releasably attached to the first attachment portion (41) of the first housing portion (33a).
(FR) Ensemble propulsif, incluant une turbomachine configurée pour être fixée à un aéronef par l'intermédiaire d'une suspension, dont certaines parties de carter peuvent être découplées afin d'atténuer certains modes de flexion de la turbomachine en cas d'avarie, l'ensemble propulsif comprenant au moins une première et une deuxième partie de carter (33a, 22) s'étendant axialement l'une après l'autre, l'une desdites parties de carter étant située en porte-à-faux par rapport à ladite suspension, dans lequel la première partie de carter (33a) possède une première portion de fixation (41) connectée de manière rigide au corps (43) de la première partie de carter (33a) et une deuxième portion de fixation (42) connectée de manière plus souple au corps (43) de la première partie de carter (33a), et dans lequel la deuxième partie de carter (22) est fixée de manière permanente à la deuxième portion de fixation (42) de la première partie de carter (33a) et de manière libérable à la première portion de fixation (41) de la première partie de carter (33a).
