Abstract

Non destructive testing of ballistic missiles engine has been industrially carried out in the Aquitaine plant of Aerospatiale for many years by means of the following methods : - infrared thermography - ultrasonics - radiography X which have been proving their complete efficiency. However, in the aim of still improving the investigation range, the sensitivity of detection and equally for decreasing the testing cost, new methods have been evaluated. Among these, holographic interferometry which is presented here in its industrially used form. The use of brand new pulsed lasers, has permitted getting rid of strict limitations of a production workshop. This article will treat in a quantitative way, the contribution of holographic interferometry to the global efficiency of the non destructive testing carried out..
