Patent attributes
The electromagnetic launcher with at least two power coils spaced from each other along an axis substantially coextensive with an intended trajectory of non-conductive, non-magnetic projectile with a projectile winding shorted by a diode. The power coils to inductively couple a magnetic flux to the projectile winding. A non-magnetic, electrically conductive electromagnetic shield positioned inside to each of power coils. Each shield has a central opening and at least one radial cut. The power coils with shields in this position keep holding by non-conductive, non-magnetic holder with the same size of central opening as the central openings of shields. A diameter of central opening is less than inner diameter of power coils and more than outer diameter of projectile. Circuit means connected to power coils for selectively and sequentially applying pulse voltages to power coils to excite the projectile winding and accelerate the projectile by pushing and pulling electromagnetic forces simultaneously.
