Abstract:
La présente invention concerne le domaine des lanceurs électromagnétiques à rails, et a plus particulièrement pour objet un lanceur à rails et un procédé associé de lancement d'un projectile comportant au moins deux rails longitudinaux connectés à un circuit d'alimentation en courant de ces deux rails, ces rails étant au moins en partie entourés par des moyens supraconducteurs aptes à générer une induction magnétique de direction perpendiculaire au plan formé par les rails et située entre ces derniers lors de la circulation d'un courant en leur sein, ce lanceur étant caractérisé en ce que ledit circuit d'alimentation comporte les moyens supraconducteurs.
Abstract:
This invention relates to launching of a flight vehicle, such as a rocket, an aircraft and the like, from a generally upwardly directed subterranean launch shaft of at least 300 m length, preferably of a length of 500 m or more. Preferably, the launch shaft is an amortized mine shaft. Launching is by means of one of, or a combination of, several possible propulsion systems. For each system, at least some components are external of the flight vehicle and associated with or mounted in the launch shaft. One kind of propulsion system may use expansion of gas in the launch shaft behind the flight vehicle. Other propulsion systems use electromagnetism or Lorentz-type actuators, such as a coil gun or gauss gun, a linear induction motor or linear synchronous motor, or a rail gun. The launch shaft mounts guiding means for guiding the flight vehicle along the launch shaft.
Abstract:
A technique for launching a missile that avoids some of the costs and disadvantages for doing so in the prior art. In particular, the illustrative embodiment of the present invention uses an electromagnetic catapult to throw the missile clear of the launch platform with sufficient velocity to attain aerodynamic flight before the missile's engine is ignited, by means of a sled travelling along a guide, whereby the sled throwing the missile moves by means of a first coil inmovable with repect to the guide, and by means of a second coil inmovable with respect to the sled.

Abstract:
Featured is a method for injection of a payload into the tissues of an organism or a body, including the steps of generating forces by electromagnetic repulsion and accelerating the payload to be injected, using the generated electromagnetic forces. The payload is thereby accelerated to a velocity sufficient for the payload to pass through the skin of the organism and be disposed in the subcutaneous tissues. The method further includes providing an electromagnetic force generating device that generates forces electromagnetically in a predetermined direction responsive to an electric current flowing through the device, wherein the step of generating includes passing an electric current through the electromagnetic force generating device to generate the electromagnetic repulsive forces used for accelerating the payload. Also featured is an electromagnetic force generating mechanism that includes a conductive member, which is configured so as to generate electromagnetic repulsive forces in a given direction to accelerate the payload responsive to a pulsed current passing through the conductive member. Additionally featured is an electromagnetic transdermal injection device including such an electromagnetic force generating mechanism, an electrical power supply and a switch that selectively interconnects the power supply and force generating mechanism to accelerate a payload such as a medicine.

Abstract:
A hybrid gun device composed of: two barrels that accept energy from combustion of standard propellant, one being operative to produce a high intensity electric current when activated; and a second in which electrical energy is produced to add accelerating energy to a projectile in the second barrel; and at least one coil stage to convert energy between electrical and kinetic to cause the projectile to be launched at hypervelocity.
Abstract:
Superconducting cables and coils are employed to create a high force magnetic suspension, which is used to suspend a carriage that is accelerated by a linear motor around an enclosed, evacuated circular track of large circumference. The magnetic suspension counteracts both gravity and radial acceleration to prevent the carriage from contacting the acceleration passage wall. A projectile is firmly clamped into the carriage. When the carriage reaches launch speed the projectile is released from the carriage into a tangential exit tube and launched through an egress hatch into the open atmosphere and, potentially, into orbit. The carriage continues around the track, decelerates, and is re-used to launch additional payloads. Multiple carriages and projectiles can be accelerated simultaneously. Radial accelerations exceeding 10,000 g's are achievable.
