Technological Challenges
Our company solves different R&D problems concerned with vibration mitigation and vibration stability improvement in various rotary systems.
- Analysis and simulation of technology factors and errors affecting the engine vibration state.
- Determination of parameter influences and acceptable values and tolerances for the rotor assembling and balancing
- Calculation the rotor imbalance and deflection limits. Definition of the rotor correction planes for low-speed balancing.
- Development of flexible rotor balancing technology.
- Development of recommendations for the design, technology and production documents improvement.
Balancing surely is the main method for vibration mitigation. The problem is extremely acute in the machine mass-production. Failure of a gas turbine engine in its acceptance test is accompanied by large financial losses.
Now this direction in our company is formulated as the development of balancing technology, taking into account the computer simulation results.
The DYNAMICS R4 models help improvement of the existing rotor balancing technnology and ultimately solve balancing problems, including those for the flexible rotors.
Results of the company engineering work in this direction usually are R&D programs to be carried out by the Customer. Besides our company engineers may accompany these works. Finally the work results are approved by an engine test.
The companies that successfully employ our experience and the capabilities of DYNAMICS R4 in technology problem solutions are UEC JSC (SALUT), UEC-Aviadvigatel JSC, UEC-Perm Motors, PJSC UEC-UMPO, A. Lyulka DB branch of PJSC “UEC-UMPO”, PJSC “UEC-Saturn”, PJSC “UEC-Kuznetsov”, JSC “MMP named after V.V. CHERNYSHEV”, JSC “UEC-Klimov”, CJSC “Ural Turbine Plant”, JSC “KMPO”.
The page photos are just some of the engines for which various technology works have been solved.
