Turbine blade image capture method for gas turbine blade using turntable on rotary table

摘要

A gas turbine blade (1) positioned on a rotary table is moved in synchronism with a digital line camera (2). The blade is positioned on a turntable (3) that rotates eccentrically on the rotary table (4). The axes of rotation of the rotary table and the turntable and the longitudinal axis of the blade are parallel. The rotation speed of the rotary table is synchronized in a nonlinear fashion with the constant rotation of the turntable.
