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 ...


In a twin-flow turbo-jet engine, a casing comprising a compressor, a combustor and a turbine, defining a path for a first flow and having upstream flange means, and downstream flange means; inner structural cowling means in the form of two half-shells; outer cowling means wherein said inner and outer cowling means define between them a path for a second flow downstream of a fan; means for mounting the half-shells to said upstream and downstream flanges of the casing; and at least one securing assembly interconnecting the inner structural cowling means an...
