Method for forming turbine blade with angled internal ribs

摘要

Two pairs of ribs define three intermediate cooling chambers. Each rib in each pair extends parallel to the other rib in the pair. The ribs in a first pair are non-parallel to the ribs in a second pair. A first rib from the first pair is positioned spaced toward the leading edge. A first rib of the second pair is then serially positioned spaced toward the trailing edge. A second rib of the first pair is then positioned toward the trailing edge relative to the first rib in the second pair. A second rib in the second pair is then positioned toward the trailing edge relative to the second rib in the first pair.
