Abstract (en)
An impingement cooling arrangement (1) for cooling a target surface in a gas turbine (10), the arrangement includes an impingement component (60) and a target component (70) having the target surface. The impingement component includes pluralities of linearly arranged impingement holes (61h, 62h, 63h) through which impingement jets of cooling air are ejected towards the target surface. The target component includes a target region (71, 72, 73) corresponding to each plurality that extends from the target surface towards the impingement component and on the target surface linearly corresponding to the linear arrangement of the impingement holes of the corresponding plurality. At least one trench (80) is present on the target surface adjacent to each target region and extends linearly corresponding to the target region. Each target region is arranged such that the impingement jets from the corresponding plurality are received on the target region and guided by the target region into the trench formed adjacent to the target region.
