New Aviadvigatel Laboratory

The new testing laboratory to test strength and reliability of materials and parts for aviation engines at the Perm design bureau has received its accreditation certificate, confirming its technical competency. The certificate was issued to Aviadvigatel by the Federal Technical Regulation and Metrology Agency and the Interstate Aviation Committee. It is valid for five years.

The laboratory was created to conduct experimental tests on the strength characteristics of materials of basic parts in engines under the program to create a family of engines based on a standardized gas generator. The main goal of the experimental tests is to create a database of material strengths. This is necessary for the transfer to the third strategy of resource management, making it possible to forecast the projected service life of engine parts without conducting lifespan tests. As a base, they are using the results of experimental estimates and results from the database on material strength.

The labs testing complex is composed of nine units made by Walter+Bai AG (Switzerland):

  • Four LFMZ electro-mechanical machines to conduct tests on low-endurance fatigue, stress-rupture strength, and creep, as well as to determine the transient characteristics of metal and alloys
  • A LFV 100 servohydraulic machine to test cyclical fracture strength with axial loading
  • A LFM 100 electro-mechanical machine to determine the characteristics of polymer and composite materials under strain, pressure, curvature, and torsion at various temperatures and humidities
  • A LFMZ 50 electro-mechanical machine to check thermo-mechanical fatigue
  • A LFV 6 servohydraulic unit to test microslides for low-endurance fatigue and cyclical fracture strength under axial loading.

In addition, the lab is equipped with a Testronic 100 high-frequency electro-resonance unit made by Rumul, to test examples for low-endurance fatigue and cyclical fracture strength.

All equipment is fitted with special kit to enable testing under high temperatures (up to 1,200) and with universal software packages, ensuring the reliability of the test results. The testing complex can work automatically and continuously, around the clock. This year there are plans to acquire another high-frequency electro-resonance testing unit.

The work of the testing complex has made it possible:

  • To improve efficiency and reduce expenses on testing thanks to exclusion of need in the advanced cyclical work for most basic parts;
  • Adopt modern technologies in designing and developing engines;
  • Provide verification of analytical models, creating new, improved parts and units for gas turbine engines for aviation and industrial applications.

Testing materials and parts is a part of meeting GOST federal standards, as well as the American ASTM standards, expanding the labs potential.

Creating a testing complex at Aviadvigatel is very important for the Perm design bureau, and for the domestic aviation industry as a whole. Aviadvigatel together with leading sector institutes CIAM and VIAM is creating a new database which in the longterm may be used by UEC, UAC, and other companies.

Additional information

Staff at the strength testing laboratory have undergone training with Walter+Bai AG specialists. The average age of laboratory workers is 27. A third of the team is studying on post-graduate courses at the Perm National Research Polytechnic University.

Aviadvigatel is a leading Russian design firm developing gas turbine engines for aviation and industrial applications. It is a part of the United Engine Corporation, a wholly-owned subsidiary of OBORONPROM specializing in engine-building assets.

OBORONPROM is a multi-faceted machine-building group of companies, founded in 2002. It is a part of the Russian Technologies group of companies. Its primary activities are helicopter building (Russian Helicopters) and engine-building (UEC).
