“…The simulation described here is not restricted to small motions or to small angles of attack, but it is based on an incompressible model for the aerodynamics. The present effort extends the work of Strganac and Mook (1990) and Luton and Mook (1993). It is not the first to use the concepts underlying the general unsteady vortex-lattice method, but it does add some innovations to the procedure.…”

“…We did not want to restrict the present simulation to linear equations of motion or periodic responses; hence, the classical approaches to resolving this dilemma were not applicable here. The present simulation is not restricted to periodic motions or linear governing equations; as a result, it can predict sub-and supercritical behavior and is a very effective tool for designing control systems to suppress flutter and reduce gust response (Mracek, 1988;Luton and Mook, 1993;Preidikman andMook, 1997a, 1998;Hall et al, 2000).…”

“…However the method has the advantage of a low computational effort when compared with modern CFD codes and can be utilized as an effective tool in the design of control systems for flutter suppression (Luton and Mook, 1993;Hall et al, 2000). Subscripts 1,2 = refer to the ending points of a vortex segments a = refer to the aerodynamic points i,j = aerodynamic panel identifiers K = refers to a vortex ring l = refers to the lower side of the panel L = refers to a control point r = refers to a particular mode of vibration s = refer to the structural points TE = trailing edge u = refers to the upper side of the panel Superscripts C = refers to the corrected solution P = refers to the predicted solution T = transpose of a matrix…”

“…Improved gust response and increased #utter stability are demonstrated for typical section type of systems. Luton & Mook (1993) combine a general unsteady vortex-lattice method with a nonlinear structural model of a cantilever wing, to perform time-domain simulations of the resulting nonlinear aeroelastic system. While this approach eliminates the need for frequency-domain aerodynamics, it prevents the use of the vast #ora of linear control techniques.…”
