Abstract : The patent application relates to a fanjet engine having the secondary air flow, for interstage seal cooling and inside vane platform cooling, supplied through a passage way into the rotor blade root attachments. The secondary air flow is directed through exit nozzles which are cast in the blade root attachments. The air leaving the nozzles flows in a direction opposite to the direction of rotation of the rotor assembly to supply additional power to the rotor assembly.
