Abstract
The invention relates to a stator part (20) comprising a platform (22), a blade (24, 26) that has a maximum camber (526), a fin (28) extending from a root (44) to a head (46), the head (46) extending from a leading edge (31) to a trailing edge (37), the fin (28) and the blade (24, 26) being arranged such that: —the maximum camber (526) lies between the leading edge (31) and the trailing edge (37); —a ratio of a distance between the maximum camber (526) and the leading edge (31) to a fin chord length (54) is between 5% and 95%; and—the fin head defines a recess (45) extending on either side of the maximum camber (526) over a recess length (47) that is less than or equal to 20% of the chord length (54).
Claims7
A stator part for a turbomachine comprising:
- a platform defining a wall of a gas flow duct,
- a blade extending radially with respect to an axis of the turbomachine from the platform, the blade having a camber maximum, and
- a fin extending radially in the duct from a root to a tip, the root being located on the platform, the tip extending axially along the axis from a leading edge to a trailing edge, the tip having a chord length, the chord length connecting, in a straight line, the leading edge and the trailing edge,
- the fin and the blade being designed such that:
- the camber maximum is axially located between the leading edge and the trailing edge,
- a ratio of an axially measured distance between the camber maximum and the leading edge over the chord length is less than or equal to 95% and greater than or equal to 5%, and
- a fin height defined between the root and the tip varies along the axis so as to define a recess in the fin, the recess extending axially over a recess length, the recess length being less than or equal to 20% of the chord length, a projection of the camber maximum along the axis lies within a projection of the recess along the axis.
