Abstract

A theoretical formulation for flutter analysis has been utilized to develop a working method for determining flutter speed of a typical subsonic aircraft wing. A Galerkin type of analysis has been used to derive the matrix form of equations from the differential equations of motion of the subsonic wing. Quasi-steady aerodynamic theory has been used to model the aerodynamic forces. A computer code in FORTRAN has been prepared for generation of matrices while the eigen value analysis is performed through MATLAB. The code is benchmarked through the flutter of a rectangular wing. The results from the code agree reasonably with those obtained from the industrial code NASTRAN.
