In this thesis, studies of flat or pancake type electromagnetic launcher systems are
described. The studies involved the development of several numerical models, and
are supported throughout by experimental investigation. The models were based on a
coaxial filamentary division technique, and the results they provided were compared
with those from a commercial electromagnetic finite element modelling package.
They were used to investigate some of the many possible launcher structures and
power supply arrangements, as part of a wide-ranging parametric study. The aim of
this thesis was to gain an insight into the factors that affect the performance of the
launchers. Several different techniques were implemented to reduce the computation
Practical experimentation provided a clear demonstration of the launcher technology,
and supplied valuable model validation data. To aid the experimental work new
projectile speed and yaw measurement systems were developed, and these were
supported by results from a high-speed camera. A novel dual projectile launcher was
tested, and was shown to improve the launch efficiency and to operate at higher
energies, due to the reduction in drive coil recoil. Projectile deformation was
investigated in both solid discs and flat annular projectiles.
