Abstract
A thermal management arrangement () in a gas turbine engine (), including: a conduit-arrangement () providing fluid communication between a compressor section () and: a relatively thermally responsive portion () of a turbine vane carrier (); and a relatively thermally unresponsive portion () of a first turbine vane carrier. The conduit-arrangement includes: a general cooling flow outlet () disposed proximate the relatively thermally responsive portion of the turbine vane carrier and configured to discharge a general cooling flow (); and an impingement flow outlet () disposed proximate the relatively thermally unresponsive portion and configured to discharge an impingement flow (). The thermal management arrangement is configured such that a flow rate of the impingement flow is effective to accelerate a thermal response of the relatively thermally unresponsive portion toward a thermal response of the relatively thermally responsive portion.
