Fluid Structure Interaction on AGARD 445.6 wing at Transonic Speeds

Aircraft is a complex structure, but a very efficient man made fly ing machine. An aircraft is a machine that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. It counters the force of grav ity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet. In this project the flu id–structure interaction problem will be illustrated using the AGARD 445.6 wing by predict ing its initial boundary condition. AGARD 445.6 wing is used because the experimental res ults are available. This configuration was chosen because extensive research has been done in the field of aero-elasticity using this model. The main objective of this project is to study the Fluid Structure Interaction over the wing of Aircraft and determine the aero elastic properties through modelling as well as analyzing the AGARD 445.6 wing structure using CATIA V5 to generate solid model and the stress analysis is done using ANSYS –FLUENT. As Flu id Structure Interaction oscillation are strong enough to deform the structure of an aircraft the so the study is quite complex as the method involves a series of iterations.
