Complex Response of an Airfoil-Store System with Structural Non-Linearity

  • The mathematic model of an airfoil-store system was simplified with the equivalent linearization method for aeroelasticity system.The parametric areas,in which there were complex flutter in the system,were obtained by introducing the subharmonic bifurcation condition of a symmetric piecewise linear oscillator.These areas were verified with numerical simulation.The results of the analyses show that,in addition to limit cycle response of cycle 1,there are complex responses,such as those in cycle 3,cycle 5,and cycle 7 etc.,in the system.
