Abstract
A blade portion of a vane is assembled to a platform portion by insertion into a cavity in the latter, in a lateral direction from an opening in the cavity, where the cavity possesses a back wall over at least a portion of its surface area. The bonding surface area between the portions of the vane is increased. The back wall of the cavity includes an inclined portion against which the portion of the blade makes contact at the end of its insertion movement, ensuring surface contact which is favorable to achieving an increased bonding area.
