  • Patent number: 9512722
    Abstract: A handheld tool facilitates the removal of an aerofoil from an array of aerofoils for an axial flow machine includes a body portion, and first and second jaw members depending from the body portion. The first jaw member is shaped to be insertable between a first aerofoil and an adjacent aerofoil in the array so as to contact a first surface of the first aerofoil. The position of the first and/or second jaw member is adjustable to selectively grip the aerofoil in use. The second jaw member is adapted to contact a further portion as a trailing edge of the first aerofoil. The tool may allow for manual levering and/or impact forces to be applied to the aerofoil. A method of removal of aerofoils is also provided, involving a sequence of manual operations using the tool. The aerofoil array may be a stator vane array for a gas turbine engine.
