The Russian Federal Service for Intellectual Property (Rospatent) published a list of top-100 inventions for 2019 and the first half of 2020. The list includes the thermal flaw detector for the aerospace industry developed by the TPU Engineering School of Non-Destructive Testing. It is a totally original device for Russia.
It provides thermal imaging of aviation materials and nodes and demonstrates structural defects of the composites. It can be used during both production and operation.
This flaw detector has no analogs in Russia. In addition, comparing with the world standards, it has unique software, which is an important advantage.
“This is our own development. Firstly, the software can simulate the material testing process to select an optimal mode. It is better to simulate the process in advance than to spend a lot of time to select modes post factum.
Secondly, the sofware contains a large set of algorithms for data processing. detector. As compared to the commercially available softwarewhich have a limited number of algorithms, our thermal flaw detector uses over a dozen of them. This diversity provides flexibility and we can work with a wider range of materials”,
Vladimir Vavilov, the head of the TPU Laboratory for Thermal Testing, says.
The flaw detector can work with composite materials and other materials with complex structure. It is these materials are being actively used the production of modern aircraft and standard testing methods are not sufficient. That are the materials that are used in the aircraft production, and the standard control and inspection methods are not sufficietnt. In aviation, there is specific damage caused by the encounters of the aircraft such as bird strikes as well as strikes from baggage, tools, hail, lightning, and other factors. Failing to find this damage in time may risk the lives of passengers and the crew.
