The gas turbine factory was founded in 1975 with a principal production programme of manufacturing rotor and stator parts and circuits for jet engines.

In 1981 the factory adopted the technology of precision blade forging becoming the only producer of its kind outside EU countries. Its technology is based on The Rolls Royce company's licence.

In 1982 the company adopted the production of centrifugal compressors for tank motors, and in 1985 it began producing rotor compressors for helicopter TV 2 and Astazou gas turbine.

In 1991 the company took on the production of axial compressors for the NK12St and NK14St stationary gas turbine, necessary for the transport of gas on Russian gas lines.

In 1996 the company developed a partnership with the CFM-i corporation regarding the fabrication of CFM 56 motor parts used in civilian aviation.

In order to carry out demanding process operations, we are equipped with equipment amongst which some parts are unique to the national engineering industry (e.g. the NC broaching machine for turbine disk slots, the CNC 5-axis grinding machines with 0,008 mm accuracy, the CNC 5-axis for simultaneously milling machines ...).

Product quality is checked in our well-equipped measuring laboratory, chemical laboratory and metallurgical laboratory.

The factory is in possession of EN 9100:2018 (TECHNICALLY EQUIVALENT TO AS9100 D AND JIS Q 9100:2016) Standard.

The gas turbine factory has been a 100 % private company since 2003.
