Abstract | ||||
This paper investigates the chaotic behavior of an in-plane electrodynamic tethered satellite system (EDTSS) operating in a circular orbit under the influence of Earth's oblateness, represented by the J2 zonal harmonic. The system is modelled using the dumbbell model, consisting of two point masses connected by an inelastic tether. The equations of motion are derived through the Lagrangian formulation, incorporating the effects of the Lorentz force generated by the current interacting with Earth’s magnetic field and the radial acceleration due to the oblateness of Earth. To analyze the conditions under which chaos may arise, the Melnikov method is applied, leading to the identification of a necessary condition for the occurrence of chaotic motion. Based on this condition, the parameter domains that are likely to result in chaotic behavior are determined. To confirm the analytical findings, numerical simulations are conducted and discussed. The results highlight the critical role of the oblateness effect and its interaction with electrodynamic forces in governing the nonlinear dynamics of tethered satellite systems. | ||||
