The Moscow-based enterprise "UEC-Salut" (part of the United Engine Corporation of the Rostec State Corporation) has created a mobile test facility for the AI-222-25 aircraft engine. The new equipment will allow engineers to check the operation of the systems of the Yak-130 training aircraft unit after repair.
The development significantly simplifies engine maintenance and speeds up acceptance testing without transportation to the manufacturer. All main systems are designed to ensure conditions as close as possible to the real operation of the engine.
Serial AI-222-25 aircraft engines are used on Yak-130 training aircraft in Russia and abroad. "UEC-Salut" is already using the development in the maintenance of power units at customer airfields. The mobile test facility has shown high efficiency: it can be quickly deployed at any site, which has significantly increased the efficiency of acceptance testing and simplified the maintenance of aircraft engines.
In real time, specialists monitor the rotor speed and vibration on the front and rear supports, the temperature of gases behind the turbine, oil and fuel pressure, as well as other critical parameters.
UEC has also completed the development of a digital twin of the AI-222-25. The advanced technology will improve the performance of the power plant and design components of new engine modifications with lower time and material costs.
Earlier, www1.ru reported that the former vice president of UAC explained why the PD-35 engine project was curtailed.
