Abstract: A nozzle of a turbine stator of a turbine engine, wherein at least two of the vanes are fixed to each inner platform and to opposite each outer platform, and a maintaining unit is configured to maintain each sector with respect to a case of the turbine stator and to connect sectors together and has a rotational maintaining element, a radial maintaining element and an axial maintaining element. The radial maintaining element is flexible so as to permit a radial expansion of each sector and is constituted by an elastic joint fixed to the case so as to surround the sectors.

Abstract: A layout for connecting two platforms of a turbomachine which support blades. A common clearance between the blades is occupied by a seal which includes a core placed in channels under the surface of the platforms and strips which close off the clearance and which are embedded in a layer of easily eroded material. Not only do the core and the strips close off the clearances, but the seal can be designed with a sufficient stiffness to oppose any excessive movement of the platforms. The strips can also be used alone without the seal.

Abstract: While remaining in one piece and unsectored, a nozzle permits a slight radial expansion of an assembly. The nozzle is formed by an inner platform mounted in a sliding manner with respect to a stator and an outer platform mounted in a free manner with respect to the case of the stator. Rods are fitted in a pivoting manner so as to radially guide and axially block upper parts of vanes, which are mounted in a sliding manner in the inner platform. The assembly is advantageously completed by gaskets. The nozzle can be used in high pressure turbines of turbojets.

Abstract: A system is described for removably attaching a pre-vaporizing bowl to the wall of the combustion chamber. The system prevents relative rotation between the pre-vaporizing bowl and the combustion chamber, as well as any relative axial movement between these elements. The system enables the pre-vaporizing bowl to be readily removed from the combustion chamber without the necessity of subjecting the assembly to any machining operations. By eliminating any welded elements, the present invention eliminates the need for transporting the assembly to a machine shop in order to disassemble the elements. The system includes a mounting member fixedly attached to an upstream end of the wall of the combustion chamber around an opening defined through the combustion chamber wall to accommodate the fuel injection nozzle. A flange, which defines a groove, extends in an upstream direction from the pre-vaporizing bowl.
