title = "Modeling and dynamic analysis of a cable towed decoy",
abstract = "The dynamic characteristics of aeronautic cable towed decoy during release have been studied extensively. The releasing process is divided into falling stage, releasing stage and towing stage. The cable is broken into arbitrary number of segments and the decoy is considered as rigid body. A multi-body dynamic model is built for the towed decoy system based on Kane{\textquoteright}s equation. Cable and decoy{\textquoteright}s airloads are considered in the dynamic model, as well as the effects of cable{\textquoteright}s motion. The decoy{\textquoteright}s aerodynamic coefficient are obtained by CFD method. An interpolation method is employed to obtain the aerodynamic coefficient at any flight speed or any flight altitude. A simplified model is built to improve the computing efficiency while it still keeps the high fidelity. Numerical simulations of the dynamic characteristics in different conditions are conducted. The results show that when the towed decoy releases at high flight speed or low flight altitude, the amplitude of decoy{\textquoteright}s pitching angle decreases and the relative position of its mass center varies smoothly.",
