Methods for assessing the technical condition of the power elements of fighter aircraft outside the assigned indicators
Abstract
According to the Vision of the Air Force, it is planned to upgrade the fleet of aircraft to new aircraft in the service of NATO countries. However, in the transition period of re-equipment with new equipment there is a problem of maintaining the serviceability of the aging fleet. The main problem in ensuring the serviceability of the Air Force aircraft fleet is a significant depletion of resource indicators due to the high intensity of flights. The purpose of the article is to publish the results of research on a set of partial methods for assessing the technical condition of the power elements of fighter jets, when their formal resource is exhausted. These partial methods are a general method of assessing the technical condition of the power elements of fighter aircraft outside the assigned indicators. The use of the general technique will allow to make more objective decisions on the continuation (increase) of the resource of the power elements of fighter aircraft and to determine their technical condition with greater accuracy. The general technique uses in the calculations the theory of probabilities in the processing of operational data, the theory of solid mechanics and the finite element method in the calculation of the stress-strain state, the method of clustering and the theory of pattern recognition in the classification of technical condition. Despite the use of such a variety of different types of mathematical calculations - the method is intuitive and quite practical.
