Description

technical field [0001] The invention relates to the technical field of electromagnetic accelerators, in particular to a small electromagnetic accelerator system. Background technique [0002] Currently commonly used electromagnetic accelerators include reluctance coil accelerators and synchronous induction coil accelerators; [0003] Reluctance coil accelerator: It consists of a series of solenoid driven coils and a yoke core of ferromagnetic material. The so-called reluctance refers to the resistance that prevents the magnetic circuit around the coil from establishing magnetic flux. Obviously, placing ferromagnetic material in the coil lumen can reduce the reluctance. As the core moves, the reluctance of the magnetic circuit around the coil changes, thus exerting a force on the core projectile. The iron core of ferromagnetic material has a greater magnetic permeability (μ p >>1). When the iron core travels to the center of the coil, the magnetic flux is easier to...

AI Technical Summary

Problems solved by technology

[0007] 1. Traditional accelerators usually adopt a single-stage acceleration mode. The surge is extremely high, and ordinary switches cannot bear it, but the price of high-power switches is extremely expensive. Moreover, even an arc-extinguishing switch will be damaged due to contact when high-voltage and high-current are connected. Resistance and ablation, resulting in short life of the switch, and the loss is also very large, making the acceleration efficiency low

[0008] 2. The traditional step-up method is low-frequency (most of them use "220V, 50HZ" to rise to high voltage through a transformer), which is bulky, heavy, small in power, and low in energy conversion efficiency.

[0009] 3. The accelerators currently in use are generally industrial and military. Although the accelerated object carries a large kinetic energy, the mass of the energy storage device is also very large. Generally, several warehouses are used to store the electric energy used for one launch.

Such a device is bulky and cumbersome, cannot be transported, and its internal structure is closed, so it cannot directly demonstrate the acceleration principle and working mechanism for people

Moreover, some modern experiments are limited by the development of computer technology, and it is impossible to calculate and analyze the nonlinear problems caused by the introduction of ferromagnetic substances in electromagnetic accelerators. Therefore, a large number of experiments are required to find a set of parameters with slightly higher efficiency (because the system There are 11 independent variables that affect the acceleration efficiency and speed), and the efficiency is generally low

[0010] 4. Traditional electromagnetic accelerators can only work in a single mode (magnetic resistance mode or induction mode)
