Abstract (en)
The assembly has apertures (101) distributed radially and equidistantly over entire length of a circumference of a disk (10) that is open toward the outside. Each aperture has a shape complementary to the shape of a foot (121) of a blade (12) to form a mounting of dovetail type. A non-metallic film (20) coated with an adhesive is placed between the foot and the aperture to cover the whole surface of the foot. Lateral walls (122) of the foot of the blade are supported against lateral walls (102) of the aperture, so as to allow the retention of the blade in the interior of the aperture. Independent claims are also included for the following: (1) a turbomachine fan comprising assemblies for mounting of the foot of a blade (2) a turbomachine compressor comprising assemblies for mounting of the foot of a blade (3) a turbomachine equipped with assemblies for mounting of the foot of a blade (4) a method for mounting of the foot of a turbine blade in an aperture of a metal support.
