摘要： In order to improve cooling of a blade 31, 41/disc 32, 42 combination, a pre-swirler feature 40, 50 is utilised in order to present coolant air through presentational pathways typically incorporating holes 37 or grooves/slots such that coolant air displaces hotter air leaked past a seal 35, 45. The swirler features 40, 50 are located within stationary housing components 34, 44 such that the coolant air is propelled at substantially the same rotational speed as the disc 32, 42 whilst presentation of the coolant air flow A, C, E is such that hot air displacement is achieved at least adjacent front faces 36, 46 of blade roots 33, 43.

摘要： A mounting arrangement 31 incorporates a blade pocket cavity 35, 135, 235 between a blade platform 34, 134, 234 and a rotor disc post 53. Coolant air is presented within the cavity 35, 135, 235 in order to provide cooling of the platform 34, 134, 234. In order to inhibit ingress of hot air from adjacent wheel spaces 36, an air curtain is created across an open end 45, 145 whereby coolant air is contained within the cavity 35, 135, 235. Air flow from the air curtain itself may pass along a surface 48, 148 to provide more direct cooling for the platform 34, 134, 234. Apertures 49, 50 may be provided in order to bleed coolant air from the cavity 35 and also draw an air flow 51 across the surface 48 for greater cooling efficiency.
