ABSTRACT
Aircraft design is multidisciplinary subject. The design process comprises complex steps such as sizing of components from a conceptual sketch, airfoil and geometry selection, thrust-to-weight ratio and wing loading, configuration layout and lofts preparation etc (Swati & Khan 2014). It is an iterative process with compromises at each step to obtain optimum results that can fulfill the future mission and user requirements as per design. One of the critical parts to be developed during an aircraft design is its landing gears (Roskam 1985). These are designed for the maximum value of localized load. Although there are critical compressions & extensions during takeoff; but worst conditions in a mission profile appear during the landing phase of the aircraft (Currey 1988). In the impact phase of landing energy dissipates involving a wider spectrum of deformation in the elastic or plastic sphere thus making the landing gear design process challenging and demanding (Wu et al. 2005).
