GAS TURBINE ENGINE COMPONENT WITH INCREASED COOLING CAPACITY

摘要

A cooling circuit for a gas turbine engine (20) comprises a gas turbine engine component (120) having a body with at least one internal cavity (122) defined by a cavity wall (130). A plurality of cooling holes (124) formed within the cavity wall (130), wherein each cooling hole (124) is defined by a length (L) extending from a cooling hole inlet (126) to a cooling hole outlet (128), and wherein the cooling holes (124) are positioned relative to each other such that a minimum allowable ligament distance (LD) is maintained between adjacent cooling holes (124) along the entire length of each cooling hole (124).
