LOW PRESSURE LOSS COOLED BLADE

摘要

A rotor blade comprises a root section, an airfoil section, a leading edge cooling cavity, an intermediate cooling cavity, and a trailing edge cooling cavity. The leading edge, intermediate, and trailing edge cooling cavities each extend spanwise through the airfoil section from a coolant inlet passage in the root section, and each terminate proximate the airfoil tip.

1. A rotor blade comprising:
a root section including a coolant inlet passage; an airfoil section including a suction sidewall and a pressure sidewall each extending chordwise between a leading edge and a trailing edge, and extending spanwise between the root section and an airfoil tip; a leading edge cooling cavity extending spanwise through the airfoil section from the coolant inlet passage and terminating proximate the airfoil tip; an intermediate cooling cavity disposed aft of the leading edge cavity and extending spanwise through the airfoil section from the coolant inlet passage and terminating proximate the airfoil tip; and a trailing edge cooling cavity disposed aft of the intermediate cavity and extending spanwise through the airfoil section from the coolant inlet passage, and terminating proximate the airfoil tip.
