Abstract

A seal assembly of a gas turbine engine includes a blade outer air seal (112), a downstream vane (114), and a pressure wall (102). The blade outer air seal (112) includes a radially outer surface (115) and the downstream vane (114) is coupled to the blade outer air seal (112) via a fluid sealing engagement (134). The pressure wall (102) is coupled to the blade outer air seal (112) and defines a metering orifice (142). The metering orifice (142) of the pressure wall (102) is configured to meter air flow from a first plenum (122) upstream of the pressure wall (102) to a second plenum (123) downstream of the pressure wall (102). At least a preponderance of the radially outer surface (115) of the blade outer air seal (112) at least partially defines the first plenum (122) and the fluid sealing engagement (134) at least partially defines the second plenum (123).
