E-rope system off-track technology is a passive off-track mode, suitable for the rocket last stage, the failure of the satellite and other abandoned aircraft rapid derailment. Aiming at the novel derailment technique, the off-orbit kinetic model under multiple coupled perturbations is studied and analyzed, and the off-track performance and the type of derailment task applicable to the technique are studied and analyzed, which is used to guide the engineering practice and control scheme design. Firstly, several de-orbit dynamic models of electric ropes under coupled perturbation are established. Based on the numerical simulation, the validity and superiority of this technique are verified. The de-orbit performance under different influence factors is studied emphatically The system parameters set the principle. Then by setting reasonable system parameters, it analyzes the applicable task types of electric rope system derailment technology. The analysis results show that the off-orbit technology of electric rope system is suitable for off-orbit mission of non-polar orbit aircraft.
