<P>PROBLEM TO BE SOLVED: To provide a tail clearance measuring apparatus capable of improving measurement efficiency and advantageous in reducing a burden on workmen. <P>SOLUTION: A tail clearance measuring apparatus 30 includes a camera part 32 and a computer 34. The camera part 32 generates an image data by imaging an inner circumferential surface 1402 of a tail part 14 and an outer circumferential surface 2002 of a segment 20 which faces the inner circumferential surface 1402. Four camera parts 32 are placed to image four spots at intervals of 90 degrees in the circumferential direction on the inner circumferential surface 1402 of the tail part 14 and the outer circumferential surface 2002 of the segment 20. The computer 34 derives a tail clearance between the inner circumferential surface 1402 of a skin plate 14A of the tail part 14 and the outer wall surface 2002 of the segment 20 based on the image data sent from the camera part 32 through a cable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
