In order to improve the performance of large caliber guns |
|
for main battlefield tank applications a wide range of |
|
R&D programs have been performed in Germany on electric |
|
and electrically supported barrel guns since 1980. In the |
|
beginning pure electric gun technologies were |
|
investigated including rail, coil and electrothermal |
|
acceleration methods. A large caliber 105 mm |
|
electrothermal gun demonstrator supplied by a 30 MJ |
|
capacitive pulsed power supply system was introduced in |
|
1995. Muzzle velocities up to 2.4 km/s were obtained with |
|
this set-up resulting in muzzle energies up to 5.8 MJ. |
|
The missing perspective on solving the energy density |
|
requirements of the pulsed power supply technology for a |
|
system realization led to the termination of these |
|
programs in the beginning of 1996. Due to its limited |
|
electrical energy requirements the technology of ETC guns |
|
has been investigated during the last years with high |
|
priority. It is the goal to provide a future main battle |
|
tank gun with increased firepower for integration into |
|
the next generation of combat fighting vehicles. Current |
|
R&D programmes result in a demonstration of the interior |
|
ballistic performance of the different ETC concepts. 120 |
|
mm ETC demonstrators are used to perform this |
|
demonstration. The presentation gives a short briefing on |
|
the results of the former investigations on pure electric |
|
guns and introduces the background for deciding to |
|
terminate these efforts. In the following an overview on |
|
the R&D Structure of the German programs on ETC and its |
|
related technology fields is presented. Basic |
|
investigations led to the definition of different ETC |
|
concepts for the realization of electrothermal plasma |
|
ignition methods and electrothermal combustion control of |
|
ETC tailored propellants and charge designs. Based on the |
|
results of 105 mm firings and of interior ballistic |
|
simulations a 120 mm ETC cartridge was designed and |
|
investigated experimentally. First 120 mm firing results |
|
will be given. |
