Abstract
The present invention relates to a cooling arrangement in which a fractal passage network is provided incorporating several passage stages. Each passage stage 4, 5, 6, 7 has substantially the same passage cross-section for consistency with other passage stages to facilitate flow pressure control across the fractal passage network. Normally, the length of passages in each passage stage are also specifically determined in order to achieve a consistent flow pressure control. The arrangement is particularly utilized with regard to cooling within turbine engine components such as blade aerofoils.
Claims10
A cooling arrangement for a component of a turbine engine, the arrangement comprising:
- a fractal network of passage stages, each passage stage having a consolidated passage cross-sectional area that is substantially equal with a consolidated passage cross-sectional area of other passage stages for flow pressure control across the fractal network.
