초록

A twin flow turbo-jet engine which includes an inner structural cowling formed by two lateral shells and which is secured through the intermediary of a securing mechanism such as fluid actuators between a forward flange and a rear flange of the casing of the engine. At least one of the securing devices enables free thermal expansion of the casing. The upstream edge of the inner cowling may include an annular seat which is in sliding abutment on the outer surface of one cylindrical annular member carried by one flange of the engine casing. The downstream ...
