Body of aerodynamic shape and method for cooling body provided in high temperature fluid flow

摘要

PROBLEM TO BE SOLVED: To provide a device for cooling an aerodynamically shaped body provided in a hot fluid flow.SOLUTION: An aerodynamically shaped body 1 extends along a camber line 100 from a leading edge 11 to a trailing edge 12 and includes a coolant supply plenum. The coolant supply plenum is delimited by a wall of the body 1. The wall of the body 1 extends from a first side of the camber line 100 toward a second side of the camber line 100 and extends over the leading edge 11, so that a leading edge wall section is provided. A first leading edge cooling duct 20 extends from an inner surface to an outer surface, is in fluid communication with the coolant supply plenum through an inlet opening 21 and opens out onto the outer surface through a discharge opening 22. The inlet opening 21 is provided on the first side of the camber line 100, and the discharge opening 22 is provided on the second side of the camber line 100. The leading edge cooling duct 20 extends inside the wall from the first side of the camber line 100 toward the second side of the camber line 100 and crosses the camber line 100 in a leading edge 11 region.SELECTED DRAWING: Figure 2
