Abstract

A seal arrangement (178;478;578) for a gas turbine engine (20) according to an example of the present disclosure includes a component (61;69;70;161;461A,461B;569A,569B) including a body having a cold side surface (180;480A,480B) adjacent to a mate face (81;181;481A,481B;581A,581B), and a seal member (82;182;282;382;482) including a leading edge region (187;287;387) and a trailing edge region (188;288;388) spaced by sidewalls (189;289;389;489;589). The seal member (82...482) defines one or more grooves (184;284;384;484;584). The one or more grooves (184...584) abut the cold side surface (180;480A,480B) to define one or more cooling passages (191;491;591), with at least one of the one or more cooling passages (191;491;591) having a flared inlet (494) defined by a corresponding one of the one or more grooves (184...584).
