Abstract:

Equations of motion and stability equations are formulated using lumped spring-mass idealization and incompressible strip theory aerodynamics control system elasticity and inertia are taken into account. One altitude only, sea level, is investigated. Solutions of the stability equations are obtained, giving flutter frequencies and complex damping coefficients required to maintain flutter as functions of flutter velocities for various values of stiffness parameter, both with and without aerodynamic balancing centering of the control surface. Both a symmetric and an antisymmetric analysis of the aileron-aileron flight tab - aileron control system are made. An analysis of the rudder - rudder trim tab - rudder control system is included and a symmetric analysis of the horizontal stabilizer - elevator - elevator control system is also made.
