Abstract

A cover plate retention system of a turbine engine (20) includes a gaspath component (300) having a hot side configured for exposure to a hot gaspath of the turbine engine and an opposing non-gaspath side (305). The cover plate retention system includes a cavity (310). The cavity has an opening disposed on the non-gaspath side, and is collectively defined by a pair of parallel side walls (312), a first end wall, and a second end wall (315). A top rail (330) is disposed at a top of the first end wall and extends therefrom along a major portion of the top of each of the parallel side walls (312). A bottom rail (332) is disposed a fixed or specified distance below the top rail (330) on the first end wall and extends therefrom along at least the major portion of each of the parallel side walls (312) to form a three-sided cover plate retention slot.A cover plate retention method for the turbine engine includes forming the cavity in the gaspath component; forming the top rail; and forming the bottom rail.
