Description

       

   <EMI ID=1.1>   <EMI ID=2.1> 

  
 <EMI ID=3.1> 

  
une lente pour atténuer ou éliminer les tensions thermiques  <EMI ID=4.1>   <EMI ID=5.1> 

  
arriéra 24. Ainsi qu'il est Lien connu dans la technique:, une pluralité de ces sections 10 d'assemblages d'aubes 

  
 <EMI ID=6.1> 

  
d'aubes de stator en une disposition axiale particulière dans le moteur. La section d'aubes montrée dans le dessin

  
 <EMI ID=7.1>   <EMI ID=8.1> 

  
elle se produira dans la paroi mince 32 du rail.

  
Dans cet exemple de mode de réalisation, la section

  
 <EMI ID=9.1> 

  
bien que la section d'aubes décrite en rapport

  
 <EMI ID=10.1> 

  
deux aubes et une seule fente pour atténuer uu éliminer les tensions thermiques dans le rail , il sera évident

  
 <EMI ID=11.1>  

  
 <EMI ID=12.1> 

  
frontale et une surface arrière caractérisée en ce que ce rail (18) comprend au moins un trou cylindrique (28) passant au travers de celui-ci , depuis cette surface frontale (22) cette surface arrière (24) et écartée radialement

  
 <EMI ID=13.1> 



   <EMI ID = 1.1> <EMI ID = 2.1>

  
 <EMI ID = 3.1>

  
slow to reduce or eliminate thermal stresses <EMI ID = 4.1> <EMI ID = 5.1>

  
rear 24. As is known in the art :, a plurality of these sections 10 of blade assemblies

  
 <EMI ID = 6.1>

  
stator vanes in a particular axial arrangement in the motor. The blade section shown in the drawing

  
 <EMI ID = 7.1> <EMI ID = 8.1>

  
it will occur in the thin wall 32 of the rail.

  
In this exemplary embodiment, the section

  
 <EMI ID = 9.1>

  
although the blade section described in relation

  
 <EMI ID = 10.1>

  
two blades and a single slot to reduce uu eliminate thermal stresses in the rail, it will be obvious

  
 <EMI ID = 11.1>

  
 <EMI ID = 12.1>

  
front and a rear surface characterized in that this rail (18) comprises at least one cylindrical hole (28) passing through the latter, from this front surface (22) this rear surface (24) and spaced apart radially

  
 <EMI ID = 13.1>
