Abstract
A device cools a disk of a turbine extending along an axis. The disk includes on its circumference at least one recess surrounded by disk teeth each having an upstream face. The recess includes a bottom in fluid communication with an upstream cavity by way of at least one lunula. The lunula includes lateral surfaces that are inclined with respect to the radial plane which constitutes the plane of symmetry of the recess into which the lunula opens.
