Comprehensive analysis on mechanical behavior of airworthy raw materials for aircraft landing gear system

Abstract

The development of new materials for the airplane and aviation is moving at a quick pace. The new materials must achieve robustness, strength, weight decrease, cost financial aspects, materials test data, and environmental- friendly. The materials test information is being utilized for the design of landing gear and other structural components for aircrafts. The landing gear comprises of shock strut, pin, bush, torsional link, wheel, tire, axle, up lock, trailing arm and retraction component. In this paper, yield and ultimate strength, percentage elongation, percentage area of reduction and young’s modulus are find out by conducting tensile test on the raw materials such as aluminium alloy, alloy steel and titanium alloy used in the landing gear system and to conduct structural analysis test on landing gear components such as pin, bush and torsional link. These significant parameters obtained from the tensile testing and structural analysis are valuable for the choice of raw materials for the structure of airplane segments. Thus, the mechanical tested data for different raw materials have corresponded with the authentication of affirmation given by the producer and in this way, this investigation will be especially helpful for assembling the landing gear segments by our Indian defense sector.
