Definitions
- the foot 10 of the moving blade 1 is composed of three functional elements:
- the invention also relates to a low pressure turbine comprising a plurality of blades according to the invention.
- the lengths of the different parts 14, 15 and 16 of the stilt 11 may be variable and adapted depending on the desired mechanical characteristics. Indeed, it is possible to increase the proportion of the curvilinear portion 15 to the detriment of the rectilinear portions 14, 16 if the foot 10 of the blade must withstand the mechanical constraints imposed. Thus, the different lengths can be modulated and optimized according to the desired weight / strength ratio. For example, the shape of the stilt 11 is determined by successive iterations by means of a CAD model and thermomechanical calculations.
- the profile of the stilt presents:
