Abstract: An airfoil includes an airfoil body that has a leading edge and a trailing edge and a first sidewall and a second sidewall that is spaced apart from the first sidewall. The first sidewall and the second sidewall join the leading edge and the trailing edge between a radially outer end and a radially inner end. The first sidewall and the second sidewall at least partially define a cavity extending radially in the airfoil body. A damper member has a free radially inner end in the cavity and a free radially outer end in the cavity. The damper member is free-floating in the cavity.

Abstract: A component for a gas turbine engine according to an exemplary aspect of this disclosure includes a surface having a plurality of cooling holes. The surface includes a first region and a second region each having a plurality of cooling holes. The cooling holes within the first region are arranged differently than the cooling holes in the second region.

Abstract: An airfoil includes an airfoil body including a first side wall and a second side wall that is spaced apart from the first side wall. A longitudinally elongated rib connects the first side wall and the second side wall and divides a cavity into a forward section and an aft section. The longitudinally elongated rib includes at least one opening fluidly connecting the forward section and the aft section of the cavity. The opening is located in a lateral central portion of the longitudinally elongated rib with regard to the longitudinal axis such that first and second sections of the longitudinally elongated rib bound respective lateral sides of the at least one opening. The opening defines a maximum dimension along a direction perpendicular to the longitudinal axis. The maximum dimension is greater than a minimum dimension of each of the first and second sections in the same direction.
