Dynamics Modeling and Simulation of Circularly Aerial Towed Cable Systems

Abstract:

The multi-body dynamics model of the towed cable is proposed in the aircraft circular motion. Based on the analysis of motion state and force of the towed cable which is established via the multi-rigid method, the dynamic simulation analysis is carried out, and the steady configuration of the rotation balance is achieved. In the same condition, it is similar to the numerical calculation configuration of micro-element method of the continuous model. All these illustrate that the new dynamic model is correct and credible, and the simulation solution is also robust and accurate. Finally, the influence of various parameters on the vertical length of the towed cable is analyzed in detail. The simulation results show that the aircraft speed is the most important factor which affects the system’s efficiency, and with some certain conditions, reasonable reducing the aircraft speed can increase the vertical length of the towed cable. The effective speed range is also calculated by the dichotomy.
