摘要：
A gas turbine engine (10) including a compressor (14), a combustor (16), and a turbine (18) in serial flow within a casing (121), said gas turbine engine comprising:
an internal passage (137) defined within a portion of said casing (121), said internal passage (137) receiving hot gases which accumulate therein when said gas turbine engine becomes inactive following a shutdown thereof; and
a gas relief valve (136) disposed in an upper portion of said casing (121) proximate said internal passage (137) and operable to open when said engine is inactive such that hot gases from said internal passage (137) are evacuated therethrough, said valve (136) being closed when said gas turbine engine is in operation.
