FLOW GUIDE ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an end wall having a nonaxissymmetric trough for reducing an interference loss between a shock wave and an end wall. SOLUTION: An end wall shape reducing shock wave power in transonic turbine machine airfoil, includes the nonaxissymmetric trough 30 extending up to a point in the vicinity of a rear edge part of at least one flow passage 24 from a front part of at least the one flow passage 24.
