SECTOR-SHAPED REAR EDGE TEARDROP ARRANGEMENT

摘要

PROBLEM TO BE SOLVED: To provide a member to be used for a gas turbine engine. SOLUTION: The member has an aerofoil portion 12 consisting of a plurality of internal cooling passages 18, 20, 22, 24 and a non-linear rear edge 16. The member also has a non-linear arrangement of a teardrop assembly 32 which forms a plurality of injection slots 30 for injecting coolant fluid into fluid crossing the aerofoil portion 12. The teardrop assembly 32 is constructed to maximize the thermal performance of the member by reducing a relative diffusion angle between the flow of the injected coolant and the flow line of the fluid crossing the aerofoil portion 12.
