A control mechanism of a vehicle-mounted system for electromagnetic launch of fire extinguishing bombs for high-rise buildings is provided. A stress wave amplifier is fixedly connected to a secondary coil, a primary coil is fixedly connected to a coil base, a guide shaft passes through a central hole in the primary coil and the coil base, and a head of the guide shaft is fixedly connected to the secondary coil. A step-up transformer TM1 boosts a 380-V alternating current and changes it to direct current to charge a pulse capacitor C1 and store energy in the pulse capacitor C1. A discharge thyristor M3 is triggered, and the pulse capacitor C1 releases the energy instantaneously. A stress wave is generated between the primary coil and the secondary coil. The stress wave is transmitted to a fire extinguishing bomb through the stress wave amplifier, to launch the fire extinguishing bomb.

A liner motor based on radical magnetic tubes includes: a dynamicer (mover, QDZ) and a stator (STA), the structure of the stator (STA) is: a stator magnetic tube (SCG) is nested into the inner wall of a pure iron tube (DTG), the stator magnetic tube (SCG) provides a radial magnetic field, a stator tube (DZGD) is formed within the stator magnetic tube (SCG), the dynamicer can travel in the stator tube; the dynamicer iron core is a tube of a radial magnetic field and installed on a tubular coil skeleton, on which winding the dynamicer coil to form the dynamicer main body; the sliders (HDZ) are installed on both ends of the dynamicer main body load.

An accelerator for a projectile includes a coil; an H-bridge coupled to the coil with four relays S1-S4, and a controller to control current flow in the coil, wherein when relays S1 and S4 are on and relays S2 and S3 are off, current goes through the coil in one direction, and when the states of the relays are switched, current direction reverses, wherein switching the current direction ensures that the projectile has a positive acceleration.

In accordance with one embodiment of the present invention, a method of multi-use multi-vision modular covers comprising of aggregating multiple devices into physical meshes and virtual networks where devices exchange multi-source data transactions and transmissions between meshed devices to project on their respective screens the exchanged images, videos, and/or visual adjustments to produce multiple video See Through streams between meshed devices in static states and/or in motion. In a preferred embodiment, the invention is combination of devices, cameras, and/or screens that produce See-Through video streams with enhancements to hide, protect, and sustain modular permutations of invisible armors, invisible cloaks, invisible vehicles, invisible crafts, invisible land drones, invisible flying drones, invisible camo nettings, and other invisible configurations managed by manager-of-manager portal platforms that can provision, manage, and monitor all these configurations and deployments during a battle while producing synergies of invisible combined arms tactics to defeat the enemies of God.

An electromagnetic launcher with a curved or spiral-shaped, open-ended guideway and conductors for launching a projectile. The projectile, movably retained on or within the guideway, is accelerated along the guideway using electromagnetic forces until it reaches an end of the guideway, then the projectile is launched in a desired direction. The direction of the launch of the projectile is determined by orienting the guideway in the desired direction using an actuator.

According to a first aspect of the present invention, there is provided a method of slowing down a moving projectile, the projectile moving within an electromagnetic railgun, the method comprising: using an electromagnetic field generated by the railgun to slow down the projectile, wherein the projectile is a munitions projectile, and/or a carrier for catching the munitions projectile.

The present disclosure relates launch systems, launch vehicles for use with the launch system, and methods of launching articles utilizing the launch vehicle and/or the launch system. In particular, various improvements for electroantimagnetic launch systems, vehicles, and methods are provided.

The invention relates to a device for projecting a projectile B using a compressed air, in particular provided to be built into a replica weapon, associated with a source of electrical energy. The device comprises a sheath (10) which receives an electromagnetic means (12) for moving a movable piston (34) within the sheath (10) between a thrust nose (14) sealing a front (10-1) of the sheath provided with a projection tube, and a breech (18) sealing a rear (10-2) of the sheath. The invention also relates to a method for controlling the device.
