STRENGTH AND BUCKLING ANALYSIS OF A COMPOSITE WING STRUCTURE USING MSC.PATRAN AND MSC.NASTRAN

The Wing of airplane considers the most important component between other components of airplane due to simple fact that the airplane has no ability to fly without wing and other elements depend on it. These importance’s of wing come from the aid of wing that it must supply airplane with sufficient lift force (L). So due to this important, modern design are achieved by using software to enhance the design and produce better results. The aim is to describe wing structure and components by using Patran 2011 by MSC Software Company and then analyze this structure by using Nastran 2011 by MSC Software Company to see the behave of this wing under strength and buckling test for different composite material and estimate the proper structure of wing and material which will provide minimum value of Equivalent stress and maximum value for buckling load factor. We will have a model of wing for small acrobatic airplane with high overloads acting on the wing (n = 12) and safety factor equal 1.5 to insure maximum safety design.
