摘要： PURPOSE:To accelerate a projectile much more and miniaturize an engine by a method wherein a branch electrode is provided at the side of the muzzle of one rail between a pair of accelerating rails provided in a launching unit to permit the igniting of a ramjet engine through the branch electrode upon accelerating the ramjet projectile electromagnetically. CONSTITUTION:When a ramjet projectile 10 is loaded into a launching passage 3 and, thereafter, a switch 6 is put ON, electric current is conducted through an annular solid armature 15 whereby the ramjet projectile 10 is accelerated electromagnetically. In this case, a through-hole 20 is formed in the projectile 10 from a suction hole 14 to an injection hole 13 and, therefore, the flow speed of air flowing through the through-hole 20, becomes about Mach 7-8 substantially the same as the speed of the projectile. Thereafter, when the projectile 10 is contacted with an initiating electrode 16 through the branch electrode 7 when the projectile 10 leaves the muzzle 3a of the rail gun 4, the excessive energy of a power supply 5 is thrown into a conductive phase 17 to explode it whereby solid fuel 12 is ignited. Then, a ramjet engine, operated by the solid fuel 12, is started and the projectile 10 is accelerated additionally.

摘要： PURPOSE:To increase a launching speed of a missile without increasing a size of an apparatus and capacity of a power source by forming an inner wall of an arcing chamber of the same material as that of a plasma producer or a material capable of producing a plasma together with the producer. CONSTITUTION:A hollow cylinder 22 is interposed between an arcing chamber 10 and a porcelain cylinder 50. The cylinder 22 is formed of the same as that of a plasma producer 12 or a material capable of producing a plasma together with the producer such as polyethylene material, polypropylene material. When the producer 12 is decomposed to produce the plasma, a plasma is produced together in the cylinder 22. This is equivalent to the fact that the cylinder 50 is reduced in thickness without increasing an entire apparatus and the producer 12 is filled in larger amount than that of a conventional apparatus. Thus, pressure of the plasma is increased, and a launching speed of a missile is increased larger than that of the conventional apparatus.

摘要： PURPOSE:To generate a convergent wave having a fast propagating speed by providing a flier for forming a disc shape for splitting a disc-shaped space in a pressure holding vessel, and charging a disc-shaped or a circular bursting charge at one side of the flier. CONSTITUTION:When a copper fine wire 19c is energized to simultaneously planely explode bursting charge 17 at its peripheral edge, the charge 17 is sequentially exploded from its peripheral edge toward its center, and a disc-shaped flier 16 made of a synthetic resin thin plate is sequentially deformed from its peripheral edge to its center toward a surface side of a lower side vessel forming member 12. Thus, a shock wave to be propagated and converged from a periphery of a space 18 toward its center to generate a shock wave, which raises gas of the space 18 to a high temperature (20,000-30,000 deg.C), to a high pressure and generates plasma in the gap by self-amplifying operation. When the shock wave reaches a center of the convergent space 18, it is reflected by a reflecting member 15 to pressurize a flying unit by breaking an aluminum foil 14d to fly it along a launching tube 3.

摘要： PURPOSE:To obtain high thrust force by centrifugally separating high temperature hydrogen generated from reactive powder due to chemical reaction with high pressure steam from oxide and injecting it in a method for shooting a rocket body by using high pressure steam due to electrothermal chemical reaction. CONSTITUTION:When a switch 8 is closed in order to shoot a rocket, a heating wire 11d is heated by energizing, water 10 in a water chamber 4b is heated to generate high pressure steam 30. Then, a rocket body 1 is slightly raised by the steam 30, and stationary power supply contact pieces 7a, 7b are connected to relatively lower terminals 6c, 6d. A powder containing chamber 15b is melted by the steam 30, reactive powder 14 is chemically reacted with the steam 30 to generate high temperature and high pressure gas. The gas is collided with turbine blades 16 to be spirally rotated to inject high temperature hydrogen 18 centrifugally separated from oxide 17 from a nozzle 3. The above injecting operation is conducted at several stages to shoot a rocket.
