Abstract
A moving blade for a high pressure turbine of a turbomachine. The blade has at least one cooling circuit including at least one cavity extending radially between a tip and a root of the blade, at least one air admission opening at one of radial ends of the at least one cavity to feed the at least one cooling circuit with cooling air, and a plurality of slots opening out from the at least one cavity and into a side of the blade in a vicinity of the trailing edge of the blade. The slots are arranged along the trailing edge between the root and the tip of the blade substantially perpendicular to a longitudinal axis of the blade, at least the slot closest to the root of the blade presenting an inclination towards the tip of the blade lying in the range 10° to 30° relative to an axis of rotation of the blade.
