MULTI-STAGE RAIL ACCELERATOR Russian patent published in 2021 - IPC H02K41/00 F41B6/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely electromagnetic launchers. A multi-stage rail accelerator contains a power housing and rails located in it, a current source and magnetizing coils, non-polar switches, a switch control system, a capacitor bank and a power source of the drive. The rail electrodes are divided in pairs into several consecutive sections located inside a common housing and forming a single accelerator channel through which the anchor moves. Each section of the separated rail electrodes is connected to its own current source, which receive commands from the control system via the control bus. The control system receives data on the position of the anchor from span sensors that record the flight of the particle in the area between the sections of the rail electrodes. The accelerator control system is connected via the control bus to the switch control device connected to the control contact of the non-polar switch. The non-polar switch closes a circuit consisting of series-connected magnetizing coils, a non-polar switch and a capacitor bank, which is connected and charged from the power source of the drive.

EFFECT: increase in the efficiency and increase of the finite speed of the anchor.
