Abstract
An aerofoilincludes cooling channelswith transfer passagesbetween adjacent channels. In normal operation, the constriction in each cooling channelensures direct through coolant airflow in the direction of arrowheads A. However, when a channelis blocked by a blockageairflow in adjacent channelsis forced through the transfer passagesin order to provide airflow in the blocked channeland facilitate cooling. This blocked channel airflow is in the direction of arrowheads B. Generally, the cross-section of the transfer passagesis determined for conformity with the outletcross-section of the channelin order to achieve substantial coolant flow balance across the coolant channelsof the aerofoil
