WebDec 23, 2016 · This paper is categorized into two parts. (1) A frame work to design the aircraft wing structure and (2) analysis of a morphing airfoil with auxetic structure. The developed design frame work in the first part is used to arrive at the sizes of the various components of an aircraft wing structure. The strength based design is adopted, where … WebThis type of beam has many applications, such as floor beams for buildings and bridges. However, there are many applications such as airplane wings and fuselages where the beam must take bending in two directions as well as torsional moments. This type of beam which can take all six generalized loads (three forces and three moments) will be ...

WebSoftware packages are to be used to design an aircraft wing spar structure and Finite Element Method (FEM) also be used to calculate the stresses developed at each station for a given bending moment. Several iterations will be carried out for the design optimization of the spar beam. The spar beam may be designed to yield at the design limit load. WebAircraft, wing box, skin, spar, stringer and ribs. 1. INTRODUCTION A wing is a lifting surface, lift is produced due to pressure difference between lower and upper surface. We study a wing box which is a part of wing of an aircraft. Wing is perpendicular cantilever beam to the horizontal plane of the fuselage.
