Abstract
A turbine blade for a turbine engine, including an aerofoil and a platform. The platform includes an internal channel having a suction opening which opens on a first surface of an upstream portion of the platform, this first surface defining a primary duct. The internal channel includes an ejection opening which opens on a second surface of a downstream portion of the platform, this second surface defining a purge cavity. The internal channel makes it possible to suck in a part of a fluid circulating in the primary duct so as to reduce the intensity of secondary flows which result from friction of the fluid on the first surface.
