ABSTRACT:
A gas turbine engine having a turbine with internally cooled, stationary nozzles incorporated into first and second stage nozzle segments and a system for supplying air to the nozzles, for effecting a flow of cooling air into impingement and film cooling relationships with a tip shoe mounted in the nozzle case, and for generating a flow of air which first impingement cools a nozzle case lip supporting the upstream ends of the second stage nozzle segments and then acts as a buffer, keeping hot gases from entering the space between the nozzles and the nozzle case.
