AIRtech Advanced Innovative Repair Technologies

Aviation Services

Researching innovative technologies and methods to improve SRUs (Shop Replaceable Units) in the repair context by using modern materials, manufacturing techniques and construction methods.

The materials and manufacturing processes currently deployed in the framework of SRU repairs match the original OEM designs. When one considers that the aircraft and equipment currently in use were, for the most part, developed in the 1970s and 1980s, it is clear that there is great potential for optimisation here. Targeted research aimed at the exploitation of this potential is now under way. The goal of the "AIRtech" project is to research innovative techniques and methods whereby an SRU can be improved within the repair framework, in terms of weight, durability and repair costs, by the use of modern materials, manufacturing processes and construction methods. The possibilities for joining conventional and high-tech materials (e.g. CFRPs with aluminium) in SRU repair is also to be the subject of scientific investigation. For the customer, the reduction in weight and the resultant reduction in fuel consumption means lower costs in airline operations. Improving the durability of the SRU enables the customer to further reduce maintenance costs and, as a direct result, operating costs.
