At the IRNITU Department of Aircraft Engineering, the defense of final qualifying works has begun. One of the first projects presented was by Sergey Terekhin. It was completed on commission from the airline S7 Airlines. In March 2025, Sergey became the winner of a hackathon for future aviation engineers in Moscow. This gave him the right to an internship and subsequent employment at S7.
In parallel with his remote internship, he worked on his graduation project. Sergey was creating a Russian equivalent of a pylon for the Embraer 170 regional airliner.
Under sanctions restrictions, the Brazilian company Embraer stopped supplying pylons to Russia (the load-bearing structure that holds the engine under an aircraft wing), creating risks for the continued operation of the Embraer 170 fleet. According to Sergey, his development is intended to ensure the carrier's long-term technical independence by offering a ready-made solution in case the existing pylons wear out.
To implement the project, the graduate carried out 3D scanning of the original assembly in order to reproduce its geometry precisely. As the material, he proposed using the domestic titanium alloy VT6 instead of a foreign equivalent. In addition, he performed a comprehensive analysis of fatigue strength, as well as a comparison of the stiffness and service life of the joint between the original and the new design.
Earlier, www1.ru reported that an IRNITU engineer developed a new technology for manufacturing the blade fairing of the Mi-8 helicopter.
