An airfoil has a body that includes leading and trailing edges that adjoin pressure and suction sides to provide an exterior airfoil surface. A cooling passage extends in a radial direction from a root to a tip. A trailing edge cooling passage interconnects the cooling passage to the trailing edge. The trailing edge cooling passage includes first and second pedestals of different sizes that are arranged in a repeating pattern with respect to pedestals of the same size and with respect to pedestals of different sizes.

Gas turbine engine airfoil trailing edge passage and core for making same

A system for creating a seal between a damper and a platform of a turbine engine component includes a turbine engine component having an airfoil portion, a platform, and a fir tree for joining the turbine engine component to a rotor, a damper located in an area beneath the platform, a seal having a sealing surface which seats against an underside of the platform, which seal has a seal retention feature which bends into contact with an underside of the damper, and which seal with the seal retention feature has a center of gravity which allows the seal retention feature to bend up as result of rotational movement of the rotor. A method for creating the seal is also described.
