COMPARATIVE ANALYSIS OF METHODS FOR DETERMINING THE MASS OF THE SHAFT OF A SPORTS AND AEROBATIC AIRCRAFT, MADE OF TITANIUM AND COMPOSITE MATERIAL

Abstract

Comparative analysis of an acrobatic aircraft's weight and shaft which is made of a titanium alloy and composite materials. The article contained requirements and specificities of an acrobatic aircraft's landing gear shaft design. The article describes prediction method of an acrobatic aircraft’s weight fraction of shaft which is allows to take into account shaft mass on wing loading upon condition that composite materials will be used in construction. Research objectives include: –Documentation of an acrobatic aircraft’s shaft design. – Analytic dependence conclusions on shaft mass by applying energy absorption of landing impact. – To quantify the algorithm of shaft mass based on strength prediction of shaft construction. –To quantify the mass and construction of shaft based on patterns that are made of titanium and composite materials. – Comparative analysis and references to practical using these methods to quantify shaft’s mass. –To quantify how shaft mass influenced by wing loading. –Designing shaft construction that is made of titanium alloy VT22 and composite material VKU26 by taking into account quantity and ply layup. Comparative analysis shaft mass which is made by different variety of composite materials. The constructive analysis is distinguished for decreasing the shaft mass that is made by composite material and references on ply layup.
