A method of enabling cooling of the engaging firtree features of a turbine disk and associated blades |
摘要 |
<p>A gas turbine engine turbine section includes a turbine disk (20) which carries a stage of turbine blades (22). The turbine blades (22) have fir tree roots (24) which locate in fir tree grooves (26) in the rim of disk 20. Some of the projections that form the fir tree roots (24) of blades (22) and fir tree grooves (26) of disk (20) are truncated so as to define spaces between their truncated surfaces and the roots between adjacent overlapping projections, thus enabling the passing of a cooling air flow therethrough. <IMAGE></p> |
