A device for effecting heat transfer to rotating equipment, in particular gas turbines, is provided. A gas turbine () comprises a first rotating unit (), i.e. an internal shaft and a second fixed unit (), i.e. a housing. A third rotating unit (), i.e. rotor blades and plates connected to the rotor blades are disposed between the first unit () and the second unit (). The first () and third () units are rotatable around a common axis () and with respect to each other. At least one device () for improving heat transfer by convection is assigned to the first rotating unit (), i.e. the internal shaft.

Device for effecting heat transfer to rotating equipment, in particular gas turbines

A gas turbine jet propulsion unit of multi-shaft-double-flow construction in which a front compressor or fan supplies compressed air into a secondary channel arranged coaxially to the propulsion unit axis and formed between outer and inner wall structures, from which a secondary air component is taken and blown out against the turbine housing structures for purposes of turbine component cooling; the secondary air channel extends essentially over the entire propulsion unit length or at least up to the area near the turbine housing structure while the secondary air component is taken off from the secondary flow by way of openings in the inner wall structure which are arranged in direct proximity of the respective turbine housing structure.
