Abstract: A multiple piece turbine rotor blade with a shell having an airfoil shape and secured between a spar and a platform with the spar including a tip end piece. a snap ring fits around the spar and abuts against the spar tip end piece on a top side and abuts against a shell on the bottom side so that the centrifugal loads from the shell is passed through the snap ring and into the spar and not through a tip cap dovetail slot and projection structure.

Abstract: A flexible seal having an X-shaped cross section that forms four contact points on four contact surfaces of two opposed seal slots. The flexible seal is used for a component in which the two seal slots undergo a large deflection such that the opposed slots are not aligned and a rigid seal will not form an adequate seal. The flexible seal can be used in a component of a combustor or a turbine in a gas turbine engine where opposed seal slots undergo the large deflection during operation.

Abstract: An air cooled turbine airfoil, such as a rotor blade, with a sequential impingement cooling circuit that provides a high level of cooling with a low amount of cooling air. The airfoil is formed of a spar and shell construction in which the spar is formed from a series of alternating layers that form the cooling circuit with the shell forming the gap for the impingement cooling channels. Two different layers form the impingement cooling channels with a third layer being a separation layer. The impingement cooling circuit includes a first impingement channel to cooling a forward half of the pressure side wall, a second impingement cooling channel to cool the aft half of the pressure side wall, a third impingement cooling channel to cool a forward section of the suction side wall, and a fourth impingement cooling channel to cool the aft section of the suction side wall.
