The present invention is to provide a launcher for an underwater vehicle by which thrust force of a mover arranged movably in a water conducting tube can efficiently be obtained. The mover forms a plurality of magnetic circuits in which magnetic flux generated by a plurality of permanent magnets flows, and the plurality of magnetic circuits includes a first magnetic circuit in which the magnetic flux flows through one of a pair of circumferential magnets, a second magnetic circuit in which the magnetic flux flows through one of a pair of axial magnets, the second magnetic circuit being formed in parallel to the first magnetic circuit, and a third magnetic circuit in which the magnetic flux flows through a radial magnet, the third magnetic circuit being formed in parallel to the first magnetic circuit and the second magnetic circuit, respectively.

A testing device for study of a magnetized plasma artillery and gunpowder, comprising a pedestal, wherein a top end of the pedestal is provided with a sliding slot for mounting a buffer device, which penetrates through an upper part of the pedestal along a front-rear direction. The sliding slot for mounting the buffer device is internally provided with a buffering slider, which can slide back and forth along the sliding slot for mounting the buffer device. A top end of the buffering slider is provided with a gunpowder combustion chamber fixing groove, which penetrates through an upper part of the buffering slider along the front-rear direction. The gunpowder combustion chamber fixing groove is internally provided with a gunpowder combustion chamber, and an upper part of the gunpowder combustion chamber is provided with a positioning ferrule for fixing the gunpowder combustion chamber.

An energy recovery pulse forming network and method that recovers at least a portion of the energy in a railgun by transferring energy dissipated from the railgun inductance back to an initial source of the energy, such as an input capacitor, for use by the network. This reduces the amount of energy required from an external power source to charge the input capacitor during subsequent railgun firings.

A magnetic apparatus and related method and energy product-by-process to motivate linear or rotational motion, comprising: at least one magnet ring tier comprising a ring of a plurality of permanent magnets; a central core comprising a permanent magnet projectile movement channel, an axis of the channel aligned in a direction normal to a geometric plane defined by the magnet ring, and running through a geometric center of the magnet ring; and each of the permanent magnets mounted in the ring at a mount angle thereof, with the components of their polar alignments parallel to the central core all oriented in the same direction; wherein: if the polar alignment of a permanent magnet projectile was introduced with a particular duality-dependent orientation into the permanent magnet projectile movement channel, the magnetic forces between the ring magnets and the projectile would be capable of motivating the permanent magnet projectile relative to the channel.

The present disclosure relates to a launch system, a launch vehicle for use with the launch system, and methods of launching a payload utilizing the launch vehicle and/or the launch system. The disclosure can provide for delivery of the payload at a terrestrial location, an Earth orbital location, or an extraorbital location. The launch vehicle can comprise a payload, a propellant tank, an electrical heater wherein propellant, such as a light gas (e.g., hydrogen) is electrically heated to significantly high temperatures, an exhaust nozzle from which the heated propellant expands to provide an exhaust velocity of, for example, 7-16 km/sec, and sliding electrical contacts in electrical connection with the electrical heater. The launch vehicle can be utilized with the launch system, which can further comprise a launch tube formed of concentric electrically conductive tubes, as well as an electrical energy source, such as a battery bank and associated inductor.
