THE POSSIBILITIES FOR OPTIMIZING THE FUNCTIONAL SYSTEM STRUCTURE OF CIVIL AVIATION AIRCRAFT

Abstract

This is an analysis of the traditional approach to systems with individual reserving reliability calculation usage. An alternative calculation method for these systems with an individual reserve system has been developed. Its application is demonstrated.

The airplanes functional systems execute many important functions: make the planer’s steering surfaces drive by mechanization means, provide the aviation engines fuel supply, provide the cabin air pressure and air conditioning in them, provide all the consumers with electricity, protect the airplane from ice, provide fire extinguishing functions, provide automatic piloting, and air navigation. The functional systems of the same type on all the route airplanes execute the same functions. At the same time, systems with the same name from different developers, or one developer, which is seen more often, on different types of aircraft, may have a different functional systems structure. With the same development in machine building, which provides a similar level of aggregate systems reliability, the reservation level is different in individual and typical aircraft system types with the same name. Such a position is connected with the absence of research in the field of the system’s optimization structure.
