Abstract
In modern high-altitude rescuing work, the traditional rescuing methods have problems of low safety and reliability. To solve this problem, a tethered-net rescuing method based on electromagnetic launching is proposed in this paper. The method launches four ferromagnetic mass blocks through the reluctance coil launchers and uses the kinetic energy of the mass blocks to drive the tethered net to fly out. Finally, the object will be trapped and the rescuing task will then be completed as long as the tethered net can be restored along with the trapped object. On this basis, the structural design of the reluctance coil launching unit is presented with its mathematical model established. The correctness of the model is verified by experiments. The exit velocity of the projectile is measured and agreed with the numerical results. The current investigation provides an important theoretical basis for the tethered-net capturing to perform high-altitude rescues.
