Substitution of the possibility of increasing the installed resource of the su-27 aircraft chassis units under the conditions of the right-wing regime martyr state

Abstract

The continuation (increase) of the established indicators of Su-27 aircraft does not fully ensure the maintenance of the airworthiness of aircraft of this type, due to the exhaustion of the established indicators of units, the resources and service lives of which differ from the resources and service lives of the aircraft, primarily the chassis units.

Due to the high intensity of the use of aircraft when performing combat missions, it was precisely the chassis group units that rapidly exhausted their resource in landings, which necessitated the conduct of in-depth research to address the issue of further safe operation of these units beyond the established indicators.

Studies of the technical condition of the landing gear units of the Su-27 aircraft were carried out in accordance with the “Program of research and work to determine the possibility of individual extension of the intended service life of more than 24 years and increase of the intended resource of the landing gear units of the Su-27 aircraft” in the conditions of an aircraft repair enterprise and operating units under the scientific and methodological guidance of the State Research Institute of Aviation.

To ensure further safe operation of landing gear units of the Su-27 aircraft, it is necessary to carry out work in the following areas:

1. to perform an analysis of cases and causes of destruction of the landing gear strut and to work out and implement proposals for preventing their destruction.
2. to continue research and work to determine the possibility of individual phased extension (increase) of the established indicators of landing gear units of the Su-27 aircraft;

Therefore, research and optimal selection of rational directions for developing a model and scientific apparatus to assess the possibility of increasing the established resource of the landing gear units of Su-27 aircraft is a relevant and important optimization problem, using assumptions, restrictions, boundaries and conditions of real operation. The purpose of the article is to determine the technical condition of the landing gear group units of Su-27 aircraft, establish the cause of the destruction of the main landing gear strut and substantiate the possibility of extending (increasing) their established indicators
