Abstract |
|
The main sections of an airplane include the fuselage, wings, cockpit, engine, propeller, tail assembly, and landing gear, etc. These parts are subjected to various loads. These loads are distributed & transferred to other load taking units of an airframe by different types of fittings namely shear fitting, bending fitting, hinge fitting etc. This project deals with the design and analysis of a typical lug shear fitting representative of an airframe structure applications. The design will provide safety against Tension tear out failure & Shear bearing failure. In this project for preliminary sizing of the lug of a shear fitting suitable method (ESDU91008) which is used in aerospace industry & acceptable to aviation authorities like FAA, EASA, etc. is followed to design the lug of shear fitting. The shear fitting design involves performing numerical calculation, creating a solid CAD & FEM model and performing the finite element analysis. For material selection appropriate reference as per global aerospace industry standards is followed. The 3D CAD model of fitting is realized with the help of CATIA V5 software and Finite Element Analysis is carried out with MSC PATRAN and NASTRAN software. |
