Improving the Aeroelastic Flutter Characteristics of Supersonic Beams Using Piezoelectric Material

Abstract: The active aeroelastic flutter characteristics of supersonic beams are investigated. The main contribution of this research is that the piezoelectric material is used to increase the flutter velocities of the supersonic beams. A modeling approach based on the conventional theory of structural dynamics is employed. The process of deriving equations is not complicated and easy to understand. This methodology is verified to be accurate and effective. Hamilton’s principle with the assumed mode method is used to de… Show more

“…where ρ , U , and M are the air density, free stream velocity, and Mach number, respectively. The non-dimensional aerodynamic pressure ( λ ) is usually used to obtain the flutter boundary (Li et al, 2011; Seyyed et al, 2012). Thus, equations (25) and (26) can be redefined as…”

“…In aerospace engineering, it is a necessity to have a fair prediction for the critical velocity for each part of high-speed aircrafts and missiles. Thus, there is a considerable number of papers about aeroelastic stability characteristics of the structures with different shapes such as beam, [24][25][26] rectangular plate, 27,28 skew plate [29][30][31] and trapezoidal plate. [32][33][34] In comparison with these types of structures, there are less number of works regarding aeroelastic stability analysis of cylindrical and conical shells and panels.…”

“…Kouchakzadeh et al [30] analyzed the aerodynamic modeling of structures by applying the classical plate theory along with the von Karman nonlinear strains and linear piston theory. Li et al [31] used the piezoelectric material to increase the flutter velocities of the supersonic beams and adopted the supersonic piston theory to evaluate the aerodynamic pressure. Kuo [32] investigated the influence of variable fiber spacing on the supersonic flutter of rectangular composite plates and later also [33] discussed the effects of hybrid fiber distribution on the critical buckling temperature, natural frequencies, and flutter boundary of composite laminates by using the finite element method.…”
