Abstract (en)
[origin: CA2897929A1] A blade of an axial turbomachine has a vane which extends radially and a first set of branches or divisions, which radially extend a radial end of the vane, and a second set of branches which radially extend the other of the radial ends of the vane and which are offset over the circumference of the turbomachine. The branches extend axially along the entire length of the vane. The sets have different numbers of branches. The branches further occupy the channel of the turbomachine and further counteract debris in the event of intake.
