Design and Analysis of Wing Root Fitting of a Medium Fighter Aircraft Made of B4C Reinforced Al7075 Alloy

Abstract

In the present work, an attempt has been made to synthesize metal matrix composite using Al7075 as matrix material with B4C particles as reinforcement using liquid metallurgy technique in particular stir casting process. Microstructural characterization was carried out for the above prepared composites by taking specimens from central portion of the casting by microstructural studies and SEM analysis. Tensile, shear, compression and bending properties of the prepared composite were studied before and after addition of Al7075 particulates to note the extent of improvement. Microstructural characterization of the composites has revealed fairly uniform distribution of B4C particulates and some amount of grain refinement in the specimens. The design and analysis of wing root fitting of on medium fighter aircraft carried out using CATIA V5 and ANSYS workbench software. Finite element method is used for the stress analysis. Calculation of equivalent stress, shear stress and total deformation will be considered under this study.
