Abstract
A high-pressure compressor (12), in particular in a gas turbine (10), has a compressor rotor (17) which is surrounded by a stator (18, 19) thereby forming a main flow channel (25) and which is delimited at the compressor outlet by an end face (30) substantially extending in the radial direction, along which end face cooling air (21) is conveyed in the radial direction for the purpose of cooling. A prolonged service life is achieved in that the end face (30) is provided with a first system (23, 24) for improving the heat transfer between the cooling air (21) and the end face (30).
Claims11
A high-pressure compressor comprising:
- a compressor rotor and a compressor stator surrounding the rotor thereby forming a main flow channel therebetween;
- a compressor outlet;
- and
- a rotor end face at the compressor outlet extending in a radial direction, along which end face cooling air can be conveyed in the radial direction for cooling;
- wherein the end face comprises first means for improving the heat transfer between the cooling air and the end face.
