Abstract
A turbomachine component or collection of components includes a first blade and a second blade and a platform from which the blades extend. The platform, between the pressure face of the first blade and the suction face of the second blade, has a non-axisymmetric surface defining a plurality of fins of substantially triangular section extending downstream of a leading edge of each of the blades. Each fin is associated with a leading position and a trailing position on the surface, between which positions the fin extends, such that the leading position is situated at between 5% and 35% length relative to a chord of the blade extending from a leading edge to a trailing edge of the blade. The further a fin is from the suction face of the second blade, the further the leading position of the fin is axially from the leading edge of the blades.
