    • A handheld tool (16) adapted to facilitate the removal of an aerofoil (4) from an array of aerofoils for an axial flow machine comprises a body portion (18), and first (24) and second (26) jaw members depending from the body portion. The first jaw member is shaped to be insertable between a first aerofoil (4A) and an adjacent aerofoil (4B) 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, such as a trailing edge (38) 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.
    • 适于便于从用于轴流式机器的翼状件阵列移除机翼(4)的手持式工具(16)包括主体部分(18)和第一(24)和第二(26)颚构件, 身体部位。 第一钳口构件被成形为能够以阵列方式插入到第一翼型件(4A)和相邻机翼(4B)之间,以便接触第一机翼的第一表面。 第一和/或第二钳口构件的位置是可调节的,以选择性地夹紧使用中的机翼。 第二钳口构件适于接触另一部分,例如第一机翼的后缘(38)。 该工具可以允许手动杠杆和/或冲击力施加到机翼上。 还提供了除去翼型的方法,涉及使用该工具的一系列手动操作。 机翼阵列可以是用于燃气涡轮发动机的定子叶片阵列。
