This paper presents an analytic study on the effect of laminate lay-up of composite missile stabilizer structure for achieving a maximum flutter speed without strength penalty. The flexible stabilizer structure in high–velocity flow may experience flutter, an aeroelastic phenomena where vibrations of the structure become unstable and can cause stability loss and flight vehicle failure. Flutter in missiles is mainly affected by the aerodynamic and structural properties of the stabilizers whereas flight vehicle body has a minor role.
