Abstract (en)
[origin: EP1251243A1] The turbine blade (11), made with a root (13) that fits into a socket (14) of a disc (12) with internal air cooling, has a deflector (20) on the blade root comprising one or more fins to channel the air circulating in the lower part of the socket to regulate the air flow towards the intake (15). The deflector can be made as part of the blade, or a separate component attached to the root of the blade and having an access port (21) for the air intake in the form of a calibrated hole. The deflector fins can lie perpendicular or at an oblique angle to the general axis of the blade.
