Revolutionary Method for Diagnosing Turbojet Engines in Assembled Condition Invented in Russia

Specialists from Smart Engines have proposed a new method for performing tomography of a jet engine in its entirety - without disassembling it into parts and in a single tomographic measurement on a serial industrial installation. Five million dollars were invested in the development of AI technology.

The specificity of jet engine research is associated with fundamentally different requirements for the materials used to create parts of the "cold" and "hot" parts of the engine.

For the "hot" part of the engine, it is important that the parts withstand overloads and high temperatures. The "cold" part, the body itself and the compressor, are created from lightweight materials to minimize the overall weight of the engine. Dense heat-resistant materials are able to absorb all radiation, and light materials are almost transparent. As a result, some real defects are not visible on the engine tomography.

Researchers have proposed a new method of non-destructive testing, combining AI technologies and computed tomography to obtain an objective tomographic reconstruction of all-metal units "as assembled." The technology builds a digital twin of the engine and allows for reliable detection of defects - cracks, voids, delaminations, as well as metal shavings - in a single measurement.
