| Summary: | 碩士 === 國立海洋大學 === 電子工程學系 === 82 === A high velocity electromagnetic launcher has been designed. The
basic working mechanism is by utilizing interaction between the
current and the generated magnetic field which will produce a J
×B force in the forward direction.The Lorenz force will acc-
elerate a projectile sitting on a rail armature to a very high
velocity.From the theoretical consideration,a constant current
generated from a high energy power supply will produce the max-
cuss the means and design of a constant current power and its
implementation on a high velocity electromagnetic launcher.
nearly constant current in the armature rail and means of over-
the distributed-type capacitors system and pulse-forming
network 5km/s and 3km/s respectively,can be achieved by two
systems.Fin- ally we explored the use of Marx generator as the
power supply for our high velocity electromagnetic launcher.The
fundamental charge them in series such that the output vlotage
becomes equal to the sum of the voltages across each capacitor.
The high current erator.In our design,4-stage Marx generator.
Each stage of Marx is placed between the Marx generator and the
railgun.It increase the current fed to the railgun reach to
800KA and the velocity of 8g projectile exceed 5km/s.For
4-stage distributed-type Marx
