Abstract

A gas turbine engine includes a turbine section including at least one turbine rotor having at least one blade (102). A blade outer air seal (104) is positioned radially outward of a radially outer tip (103) of the at least one turbine blade (102). The blade outer air seal (104) has a forward hook (106) and an aft hook (108). The forward hook (106) is supported on a forward retainer (110) and the aft hook (108) is supported on an aft hook retainer (124). The aft hook retainer (124) provides structure to prevent rotation of the blade outer air seal (104) relative to the aft hook retainer (124). There is an interference fit between the aft hook retainer (124) and the forward retainer (110). A load path is provided from a static structure through the aft hook retainer (124) to the forward retainer (110).
