Abstract

In the aerospace industry the accuracy of product geometry and the aerodynamic contour  provided traditionally, by the mould loft template method. The assembly accuracy control is carried out using optical measuring instruments, such as a level and a theodolit in combination with leveling rulers came to the aircraft industry from geodesy. Measurements are carried out according to reference points pre-embedded in the product at the design stage.

The introduction of modern high precision coordinate measuring machines (CMM) into the production cycle is promising and actively developing direction to improve the quality of manufactured aircraft. To control the geometry of parts and assemblies, stationary portal-type CMMs and mobile CMMs of the "hand" type replace traditional rod tools and templates, and in the assembly and control operations of the product, traditional optical devices are replaced by a laser tracker.

The aim of this paper is the use of laser trackers for non-contact real-time large-sized product shell displacement measurement under static loading, which makes it possible to reduce the complexity and duration of tests, and ensure high measurement accuracy.
