    • An alignment tool for measuring an amount of angular misalignment (d) between the forward frame (16) and the aft frame (20) of a gas turbine engine (10) arranged in spaced apart relation to each other along a rotational axis (15), each of the forward frame and an aft frame having a mount (40,92) for attachment of the engine frame to a base feature. The alignment tool comprises a projection tool (28) configured to attach to the mount (40/92) of one of the forward frame and the aft frame and a display tool (26) configured to attach to the mount (92/40) of the other of the forward frame and the aft frame. The projection tool includes a body (32) and a position projector (36) mounted to the body and configured to project a marker (30) onto the display tool to indicate a relative angular position of the projection tool.
    • 一种用于测量沿着旋转轴线(15)彼此间隔开地布置的燃气涡轮发动机(10)的前部框架(16)和后部框架(20)之间的角度不对准量(d)的对准工具, ,前部框架和后部框架中的每一个具有用于将发动机框架附接到基部特征的安装件(40,92)。 对准工具包括被配置为附接到前框架和后框架中的一个的支架(40/92)的投影工具(28)以及被配置为附接到支架(92/40)的显示工具(26) 前部框架和后部框架中的另一个。 投影工具包括主体(32)和位置投影仪(36),位置投影仪安装到主体并且被配置为将标记(30)投影到显示工具上以指示投影工具的相对角位置。
