Abstract

L’invention consiste en un composant structurel d’échappement (20), pour propulseur BLI situé à l’arrière du fuselage et comprenant une soufflante entrainée en rotation par une turbine (5). Le composant structurel d’échappement (20) comprend un flasque de fixation (19) configurée pour être fixée sur une partie arrière du fuselage et une deuxième partie reliée mécaniquement à la première partie (19) et s’étendant vers l’arrière. La deuxième partie formant une tubulure (24) par laquelle s’écoulent des gaz d’échappement de la turbine. De plus, un moyeu (17) relié mécaniquement à la deuxième partie est agencé coaxialement à cette dernière. Le moyeu (17) guide en rotation et maintient axialement un arbre de soufflante. Le composant structurel d’échappement (20) est adapté à fixer à la partie arrière de fuselage le groupe propulseur. Ainsi, le composant structurel d’échappement (20) remplit plusieurs fonctions. Figure pour l’abrégé : Figure 2The invention consists of a structural exhaust component (20) for a BLI thruster located at the rear of the fuselage and comprising a fan driven in rotation by a turbine (5). The exhaust structural component (20) includes an attachment flange (19) configured to attach to an aft portion of the fuselage and a second portion mechanically connected to the first portion (19) and extending aft. The second part forming a pipe (24) through which the turbine exhaust gases flow. In addition, a hub (17) mechanically connected to the second part is arranged coaxially to the latter. The hub (17) rotationally guides and axially holds a fan shaft. The exhaust structural component (20) is adapted to attach the power unit to the rear fuselage. Thus, the exhaust structural component (20) performs several functions. Figure for abstract: Figure 2
