Paper Abstract

Large numbers of borescopes (endoscopes) are used by the Royal Air Force for inspection inside engines, wing panels, etc. There is a need to establish specifications for borescopes, and test procedures to ensure that they meet the specifications both initially and after use or maintenance. A representative sample of 59 units was studied, by Sira Limited, to confirm the suitability of certain test methods and to facilitate writing a test specification. The trends of the results are presented, together with a description of the proposed test equipment under the general headings of resolution, glare, photometry and sundries. It is expected that equipment will be installed within the year, and that borescope specifications of the new type will gradually be introduced.
