[0019] FIG. 1 is a perspective view of a moving blade 10 in accordance with the present invention, e.g. for a high pressure turbine in a turbomachine. This blade has a longitudinal axis X-X and it is fixed to a rotor disk (not shown) of the high pressure turbine by means of a root 12 that is generally in the shape of a fir-tree. It typically comprises a base 14A, a tip 14B, a concave wall 16A, a convex wall 16B, a leading edge 18, and a trailing edge 20. The root 12 joins the base 14A of the blade at a platform 22 defining an inside wall for the stream of combustion gas flowing through the high pressure turbine.
[0020] Such a blade is subjected to the very high temperatures of the combustion gases and it therefore needs to be cooled. For this purpose, and in known manner, the moving blade 10 has at least one internal cooling circuit made up, for example, of at least one cavity 24 extending radially between the base 14A and the tip 14B of the blade. This cavity is fed with cooling air...
