The defense of graduate qualification works has begun at the Department of Aircraft Construction of IRSTU. One of the first to present was Sergey Terekhin's project. It was commissioned by S7 Airlines. In March 2025, Sergey won a hackathon for future aircraft 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 a diploma project. Sergey created a Russian analog of the pylon for the Embraer 170 regional airliner.
Under sanctions restrictions, the Brazilian company Embraer stopped supplying pylons (a силовая конструкция, удерживающей двигатель под крылом самолёта) to Russia, which creates risks for the further operation of the Embraer 170 fleet. According to Sergey, his development is designed to ensure the long-term technical independence of the carrier, offering a ready-made solution in case of wear and tear of existing pylons.
To implement the project, the graduate performed 3D scanning of the original assembly to accurately reproduce its geometry. He proposed using domestic VT6 titanium alloy instead of a foreign analog as a material. In addition, he performed a comprehensive analysis of fatigue strength, as well as a comparison of the stiffness and service life of the connection between the original and new structure.
Earlier www1.ru reported that a new technology for the production of the Mi-8 helicopter rotor blade fairing was developed by an IRSTU engineer.
