Mathematical formulation for aeroelastic analysis of low aspect ratio box beam structured delta wing immersed in incompressible flow is analyzed in this paper. An algorithm based on Hamilton’s variational principle and Galerkin approach has been used for the determination of divergence instability of a delta wing structure at high angle of attack. The structural model incorporates non classical effects such as anisotropy. As compared to moderate swept wing, the nonlinear lift terms corresponding to that of vortex lift comes into effect in a highly swept delta wing. Polhamus leading edge suction analogy concept has been used for calculating the nonlinear terms. The box beam structure and Polhamus concept are used together for the formulation of the stability of the fluid structure interaction problem.
