Cooled turbine rotor wheel, in particular, a high-pressure turbine rotor wheel for an aircraft engine

摘要: On a high-pressure turbine rotor wheel, where blade neck interspace (14) exists between two adjacent blades (4) which is defined by the disk lobe (2) and opposite necks (5) platforms (6), part of air supplied cooling channel (9) passed via diverter (10) into to effectively cool rim (1) in this area simultaneously supply low-pressure channels (12) with cooler displace hot sealing air. Thus, life wheel increased simple means.
