AL-41ST-25 was developed at the A. Lyulka Design Bureau and created by specialists from the Ufa enterprise UEC-UMPO. It surpasses existing analogues of engines of the same class in terms of power, efficiency, and time between overhauls.
Its design efficiency is 39.1% with the possibility of a phased increase to 40%. The design efficiency of analogues does not exceed 38.5%. .The engine meets Russian and international environmental standards and will operate for at least 120 thousand hours. Its projected lifespan will increase to 150 thousand hours.
Testing the "heart" for units that provide the necessary pressure for gas transportation through gas pipelines was initially conducted on UEC-UMPO stands.
Later, the AL-41ST-25 was installed at the "Arskaya" compressor station in Tatarstan, where it will undergo pilot industrial operation. During comprehensive 72-hour tests, the prototype engine successfully coped with the tasks.
