The article presents the views of the authors regarding the problem of controlling the exhaustion of the resource of aircraft power elements by modern means of non-destructive control based on the phenomenon of corrective force and the possibility of predicting their ultimate (pre-destructive) state.
Since the beginning of full-scale hostilities on the territory of Ukraine, caused by the full-scale invasion of the Russian Federation, the aviation of the Air Force of the Armed Forces of Ukraine has been effectively performing combat tasks as assigned. However, this led to a significant increase in the intensity of use of aviation equipment and an increased depletion of the resource indicators of all units, especially those that differ from the airframe resource. Since the rearmament has not yet been completed, research and work is being carried out to extend the assigned resource indicators of individual units and component products. In the article, the main attention is paid to the chassis riser of the Su-27 type aircraft, as the most critical from the point of view of flight safety and resource residues.
The article also analyzes the theoretical foundations of such a non-destructive testing tool as the phenomenon of coercive force and gives the advantages of this tool over others, especially since this method allows you to estimate the residual resource and monitor the limit state of the material.
The results of tests of the method of non-destructive testing based on the phenomenon of coercive force on the responsible (from the point of view of flight safety) structural element of the aircraft - the main landing gear of the Su-27 type aircraft are presented. Compared experimental data with tabular data.
At the end, the algorithm for measuring the coercive force on the object under study is given.
The use of the specified method makes it possible to more objectively solve the issue of determining the technical condition of individual power elements of different types of aircraft, and also provides an opportunity to more reasonably make decisions about the extension of resource indicators assigned to these elements by the developer.
