Abstract :
The present study outlines a procedure to evaluate flutter characteristics of a Bisplinghoff Ashley and Halfman (BAH) wing. The flexibility matrix has been derived using bending, torsion and shear stiffness distribution along the span of the wing. The procedural aspect of deriving the dynamically coupled energy equivalent mass matrix is outlined. The aerodynamic matrix used can be derived using the doublet methods. Nastran package has been used to develop the aerodynamic influence coefficient matrices using the doublet in strips. The final flutter analysis has been computed to verify the procedural aspects of the calculations.
