Summary:PROBLEM TO BE SOLVED: To shorten the length of the stopping time of aircraft by enhancing accessibility to the engine during maintenance operation and to assure the transmission of the force of the engine to the aircraft and the sufficient rigidity of the turbojet engine. SOLUTION: This twin-flow turbojet engine comprises a cylindrical casing having an annular flow space formed on the outside for a secondary flow. The cylindrical casing comprises a lattice-like framework and a detachable cowling panel secured to the framework. The framework has an upstream side annular flange for securing it to an intermediate housing, a downstream side annular flange for connecting it to an exhaust housing, and a rigid beam interconnecting two flanges, parallel or tilted to the axis of the turbojet engine.
