Structural and Vibrational Analysis of Model Aircraft Tapered Wing

The airplane wing design plays very important role to decide the main purpose for which it will be used at the later stage. The design and shape of the wings plays a important role to decide operation for which the plane will be used. Design of Airplane wings are done in such a way that it become the air borne and can produce lift, which will be greater than the weight of the plane including the weight carrying capacity of the airplane. The lift force is required to carry the plane into the air and this lift force is generated by the specific design of the wing of the airplane. Different type of forces acts on the wing which makes the airplane airborne. In order to understand this lifts the combination of Bernoulli's and Newton’s Principle helps a lot.The wing of approx every airplane have such a profile in which there is curved at the top and flat at the bottom. This type of designing is done to make the movement of air faster at the bottom which creates the difference in the pressure and results into the generation of lift force. So we can say that the design of wing plays important role to find out the limitation of the airplane. Aircraft wing analysis helps to perform structural and Vibraional analysis of an aircraft wing. Finite element method has been used to formulate the structural and free vibrational analysis on the tapered wing of prototype airplane made up of Balsa wood. ANSYS 12.1 analysis software is used as a mathematical tool in implementation of the analysis and to extract the results and to come on to certain results regarding the wing. Free vibration study represents one of the most important studies for complex structure such as wing structure. In this research, a model for tapper wing structure was created including the airfoil shape using ProE-5 modeling software. The airfoil of the tapper wing is designed using NACA airfoil software. ANSYS 12.1 were the benchmark to proceed for the detailed Structural and Vibrational analysis of the complete tapper wing.
