SYSTÈME ET PROCÉDÉ DE RÉDUCTION DES TEMPÉRATURES MOTEUR APRÈS ARRÊT

摘要

A cooling system 100 configured to reduce a temperature within a gas turbine engine 110 in a shutdown mode of operation includes a first gas turbine engine 110 including a compressor 124 having a bleed port 138. In a first operating mode of the gas turbine engine 110, the compressor 124 bleed port (138) is configured to channel a high pressure flow of air from the compressor 124. During a shutdown mode of operation, the compressor 124 bleed port 138 is configured to channel an external flow of cooling air into the compressor 124. The cooling system 100 also includes a source of cooling air 156 and a conduit 144 coupled in flow communication between the compressor 124 bleed port 138 and the source of cooling air 156. The source of cooling air 156 configured to deliver a flow of cooling air into the compressor 124 through the compressor 124 bleed port 138.
