1 Defense technology Railgun Průdek Jaromír Brno University of Technology Faculty of Mechanical Engineering

2 Contents Vocabulary Coilgun Railgun - History - Principe - Today record of railgun - Weapon in Modern Warfare

3 Vocabulary Coil-cívka Susceptibility-vnímavost Jamming-rušení Indirect fire-nepřímá střelba Vulnerability-zranitelnost

4 Coilgun -invented by Kristian Olaf Birkeland (1867 –1917) -using magnetic forces to accelerate projectile -projectiles are ferromagnetic

5 History of Railgun -invented by Louis Octave Fauchon-Villeplee in first plans to use railgun, was purposed by Germany's Ordnance Office in first large-scale railgun build in 1970 by John P. Barber in Australian National University -today biggest railgun located in Virginia, USA (at Naval Surface Warfare Center’s Dahlgren Division Laboratory)

6 Railgun in Virginia

7 Principe of Railgun -using magnetic forces to accelerate projectile (Lorentz Force)

8 Today record of railgun Speed of projectile: 3,2km/s Weight of projectile: 3,6 kg Kinetic energy of projectile: 33MJ

9 Weapon in Modern Warfare -first military railguns will be produced for next generation of cruisers -projectiles using kinetic energy to destroy target -railgun will be powered by small nuclear reactor -range of railgun 2-3 times bigger than standard technologies (Medium Range missiles) and 10 times bigger than naval cannons
