Moscow-Magnitogorsk and Sverdlovsk-Moscow routes was given the status of an independent enterprise of the USSR Civil Air Fleet. From the first years of work, the repair of Po-2 aircraft and M-11, M-17 engines was mastered, and later the enterprise began to repair the ASh-62IR engine, one of the most mass-produced products for civil aviation of those years. In the post-war years, the enterprise specialized in the repair of ASh-82FN engines for Il-12 aircraft, and then mastered the repair of ASh-82T for Il-14.
During this period, a production repair line was created, which made it possible to repair several thousand motors a year. Developing your competencies the plant mastered the overhaul of R-5 gearboxes and ASh-82V engines for the Mi-4 helicopter. Their repair was carried out until 1987, when, one might say, the piston era ended.
In turn, the plant mastered the repair of gas turbine engines in 1973, when work began on TV2-117A turboshaft engines. Two years later, the range of services was expanded to include the VR-8A main gearbox for Mi-8 helicopters. The repair of these products, as well as the more modern TV3-117, VR-24 gearboxes and AI-9V auxiliary engines, ensured the presence on a very capacious market of units for the world’s most massive heavy helicopters of the Mi-8 family.
Another area of work was the repair of gas turbine engines: work on the NK-2-8 and D-30KU-154 was mastered. Finally, as the demand for the repair of aircraft engines for Soviet-made airliners began to fade, the plant began work on land-based industrial engines, such as the NK-12ST and NK-16ST. A new direction is being mastered – the repair of PS-90GP-2 engines for gas pumping units.
Engine repair continues to be the most significant part of UZGA’s business. According to the results of work in 2020, in the total revenue of 25.226 billion rubles, this area took more than 23%. The prospects for the repair of engines are twofold: on the one hand, the division’s production program is based on the repair of products at the final stage of their life cycle. Of course, both TV2-117 and TV3-117 engines, and helicopter gearboxes will need to be repaired for many years, since the fleet of Mi-8T/P and Mi-8MTV/AMT helicopters still numbers hundreds of machines.
Gas pumping units will also require timely repairs and upgrades. For an aging fleet of engines, the production of an increasing number of components used in maintenance and repair will need to be mastered independently. For example, not so long ago launched section of pipelines today operates almost at full capacity. But the engines repaired at UZGA are not eternal. You need to learn new products.
