Abstract
The arrangements and the methods serve for the efficient and reliable cooling of components,in particular in turbomachines, even in the event of a local increase in the static pressure,of a hot fluid which flows over the component. In order to ensure sufficient cooling of the components,the distance between the cooling holes,is in each case selected in such a way that the cooling holes,in the region of increased static pressure,of the hot fluid are at a smaller distance from one another than in the regions of lower static pressure. A typical design of the invention is shown in FIG.
