Diagnostics of Gas Turbine Engines and Gas Turbines
Aviadvigatel OJSC systematically does much to assure high reliability of gas turbine engines for aviation and industrial application and their safe operation, develops engine technical condition inspection and diagnostics methods, requirements to ground-based and onboard monitoring and diagnostic systems, provides consulting services with respect to diagnostics-related support of its engines.
Parametric Diagnostics of Aero Engines
ASD-Diagnos-90 computer-aided diagnostic system developed by Vzlet-Premier SPE is used to provide high performance of PS-90A engine. This system is based on flight data processing algorithms developed by Aviadvigatel's specialists in cooperation with operating companies.
In 2009-2010 an updated software ASD-Diagnos-90 version 3.1 was put into operation. It is based on optimized algorithms. The program has got an improved interface and data base structure that provides more comprehensive flight data evaluation as well as extended capabilities of processing result analysis.
Algorithms of on-ground processing of flight data ensure:
- check of flight data adequacy
- check of adequacy of engine and engine systems faults and failures messages recorded by the airborne recording system
- determination of engine operating time
- check of engine parameters during start-up
- check of flow path parameters
- check of oil system parameters
- automated mechanisms operation check
- thrust reverser operation check
- engine vibration monitoring
The automated systems that are built based on these algorithms ensure continuous monitoring of the airline engine fleet technical condition that allows significant saving of engine operation and maintenance costs and improving flight safety.
Aviadvigatel OJSC specialists developed the software allowing fast and qualitative verifying, optimizing and improving the already existing algorithms and significantly simplifying development of new engine technical condition monitoring and diagnostics algorithms taking into account the previously acquired information stored in data bases.
Expert D-30 software developed by Aviadvigatel OJSC is designed for expert analysis of D-30, D-30KU, D-30KU-154, D-30KP engines technical condition based on run-up data and flight charts. If you would like to receive further information concerning Expert D-30 software and its purchasing, please contact us.
Parametric Diagnostic of IGTsTraditionally Aviadvigatel OJSC pays a great attention to reliability, safety and high efficiency of its gas turbines. Besides thorough design study it is achieved through using protection systems, on-line monitoring systems and automated systems of gas turbines diagnostics.
Sufficient instrumentation and use of digital automatic control system for gas turbines, gas pumping sets and gensets control makes it possible to use parametric data for efficient diagnostics of gas turbine technical condition during operation.
Compressor Controls Corporation with Aviadvigatel active support developed a gas turbine parametric diagnostics subsystem (PDS) as part of automatic control systems of gas pumping sets. PDS is a shop-level subsystem installed into a separate computer. If necessary, PDS can be customized to Ural gas pumping sets equipped with an automatic control system of any manufacturer.
Tribology-based Diagnostics of Aero Engines and IGTs
Aviadvigatel OJSC has experience in development of the methods of gas turbine engine technical condition diagnostics by oil-wetted parts wear particles, and the methods of fault search and elimination at increased content of wear particles in oil.
The key instruments of tribology-based diagnostics are spectral and ferrography analyses.
Spectral analysis of oil samples allows determining the concentration of wear debris in an oil system, which varies depending on wearing rate. There are special programs that make it possible to determine the grade of debris material using the same equipment thus significantly improving the accuracy of defect source determination.
Ferromagnetographic analysis of oil samples allows determining the size of wear debris and wear nature. For oil samples analysis, wear debris type books were compiled and engine components failure identification methods were developed. Atlases of wear particles are made and engine component fault detection methods are developed to perform oil samples analysis.
