Ramped tip shelf blade |
摘要 |
<p>A gas turbine engine blade (10) includes pressure and suction sides (18,20) extending between leading and trailing edges (22,24) and root (26) to tip (28). The pressure side includes a tip rib (40) recessed therein to define a tip shelf (46) terminating in an inclined ramp (44). The ramp may be aligned with streamlines of combustion gas flow for preventing interruption thereof and the increase of heat transfer therefrom. <IMAGE></p> |
