Abstract
A tool for correcting the twist angle of a turbine blade includes an adaptor configured to engage a tip of the blade, a socket drive configured to engage the adaptor, a first handle connected to a first side of the socket drive, a second handle connected to a second side of the socket drive, and a torque gauge configured to measure a load applied to the blade.
Claims18
A tool for correcting a twist angle of a turbine airfoil, the tool comprising:
- an adaptor configured to engage a tip of the airfoil;
- a drive member configured to engage the adaptor;
- a first handle connected to a first side of the drive member;
- a second handle connected to a second side of the drive member, the first and second handles configured to transmit a twisting load to the tip of the airfoil through the drive member and the adaptor;
- and
- a torque gauge mounted on the tool and configured to measure the twisting load applied to the airfoil by the tool.
An apparatus for correcting a twist angle of a turbine airfoil, the apparatus comprising:
- a base plate;
- a fixture connected to the base plate and configured to engage the root of the airfoil;
- a twist angle gauge connected to the base plate and configured to measure the twist angle of the airfoil;
- and
- a tool configured to apply a measured load to a tip of the airfoil, wherein the tool comprises:
- an adaptor configured to engage a tip of the airfoil;
- a socket drive configured to engage the adaptor;
- a first handle connected to a first side of the socket drive;
- a second handle connected to a second side of the socket drive, the first and second handles configured to transmit a twisting load to the tip of the airfoil through the socket drive and the adaptor;
- and
- a torque gauge configured to measure the twisting load applied to the airfoil.
