THE DEPENDENCE ANALYSIS OF DURABILITY, THE CATASTROPHE RISK AND THE TRANSPORT EFFECTIVENESS ON THE AIRPLANE CONSTRUCTION MASS

Abstract

The analysis of conditions to provide durability, reliability and the transports effectiveness of the civil aircrafts is performed.

One of the main perfection characteristics of the civil aviation airplanes is ratio between the construction mass to the quantity of passenger seats, i. e. the airplane construction mass per a passenger seat. The lower this index is, the higher the airplane economic effectiveness will be. From the other hand, decreasing the construction mass is connected with decreasing its durability and increasing the catastrophe risk. In the work the attempt to analyse the conditions and restrictions within the limits of minimizing aircraft deadload is done. The maximal take off mass of the airplane max M may consist of: the payload mass П.Г M (passengers and cargos), the fuel mass Т M and the airplane construction mass К M . For example, for the airplane Tu-204, the flying mass components are: Mmax = 107,9 T; П.Г M = 25,2 T; Т M = 32,7 T; К M = 50 T.
