Project summary

Purpose of project: Development and approval of a process of automatic monitoring of loading and service life of critical components of D-30KU-154 main engine in Tu-154M aircraft. Such monitoring is to be based on flight data representing progressive deterioration of engine critical components as a function of engine modes (their nomenclature and duration) in a specific flight.

The project is aimed at developing a complex system of organizational, technical, technological, informative and mathematical instruments which will make it possible to analyze the process of tracking the loads and service life of main parts of engine D-30KU-154 in aircraft TU-154M. It is also intended to demonstrate the possibility of reducing the engine operation expenses without impairing (or even with simultaneous enhancement) of aircraft flight safety by radically improving the engine condition monitoring procedures (these procedures will be based on experimentally established and theoretically substantiated correlations between progressive deterioration of engine most heavily loaded components, on the one hand, and. different engine modes and their duration in actual flight, on the other hand).

Technical approach

The "on-condition maintenance" principle implies that every particular engine is operated in accordance with the results of analysis of its inpidual characteristics, features and service conditions. The solution of the problem as stated in the project is to be achieved by using the methods which have already been worked out in the main by the participants in this project specializing in aerogasdynamics, methods of control of loading and service life of turbine plant components, flight testing and operation of aircraft, information science and computer programming.

Hence, there is good reason to expect the results of applied research and development under the project to be an appreciable contribution to the enhancement of the efficiency and safety of Tu-154M aircraft and, viewing the project from a long-term perspective and taking into account the high level of research and technology in defense industries, as well as the latest achievements in the field of research, to the solution of similar problems with other Russian civil aircraft.

In the long-term view, the implementation of this project will offer ample opportunities for joint work with foreign partners in the field of application modern ground and airborn acquisition and computer devices. Such cooperation may be possible, for instance, with Teledyne Controls in the area of updating airborne measuring systems in Russian aircraft and fitting them with highly reliable solid-state data acquisition devices.
