Abstract
An airfoil includes a body that has a platform, an airfoil extending outwardly from a side of the platform and a root extending outwardly from another side of the platform. A member is connected in an articulated joint to the body.
Claims21
An airfoil comprising:
- a body including a platform, an airfoil extending outwardly from a side of the platform and a root extending outwardly from another side of the platform, the body having one of a socket or a socket member that are connected together in an articulated joint;
- and
- a member including the other of the socket member or the socket, the socket member irremovably interlocked with the socket such that the socket member cannot be removed from the socket non-destructively.
An airfoil comprising:
- a body including a platform, an airfoil extending outwardly from a side of the platform and a root extending outwardly from another side of the platform;
- and
- a member connected in an articulated joint to the body, the articulated joint including a socket and a socket member movably interlocked with the socket, wherein the socket is a slot and the socket member is a button having a shank and enlarged head on the shank.
A turbine engine comprising:
- optionally, a fan;
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor, the turbine section being coupled to drive the compressor section and the fan, and
- at least one of the fan, the compressor section and the turbine section including an airfoil having a body including a platform, an airfoil extending outwardly from a side of the platform and a root extending outwardly from another side of the platform, and a member connected in an articulated joint to the body, the articulated joint including a socket and a socket member movably interlocked with the socket, wherein the socket is a slot and the socket member is a button having a shank and enlarged head on the shank.
3 more elements
A method for processing an airfoil, the method comprising:
- depositing multiple layers of a powdered metal onto one another;
- joining the layers to one another with reference to data relating to a particular cross-section of an airfoil;
- and
- producing the airfoil with a body including a platform, an airfoil extending outwardly from a side of the platform and a root extending outwardly from another side of the platform, and a member connected in an articulated joint to the body, wherein the body has one of a socket or a socket member that are connected together in the articulated joint, and the member includes the other of the socket member or the socket, the socket member irremovably interlocked with the socket such that the socket member cannot be removed from the socket non-destructively.
1 more element
A method for processing an airfoil, the method comprising:
- providing an airfoil that includes a body having a platform, an airfoil extending outwardly from a side of the platform and a root extending outwardly from another side of the platform;
- providing a damper member including a damper body;
- and
- forming an articulated joint to connect the body and a damper member together such that the damper body extends adjacent the platform, the articulated joint including a socket and a socket member movably interlocked with the socket, wherein the socket is a slot and the socket member is a button having a shank and enlarged head on the shank.
