Electromagnetic Railgun - Instrumentation

Purpose


  • Railgun
    • control
    • investigation
    • improvement.

Skills

  • In-boremetrology
    • microwave technology
    • high magnetic field sensors
    • X-ray imaging
    • radio link from projectile to laboratory
  • Active velocity control during launch.


CMR B-scalar sensor and electronics
Active area (W x L x H):
50 mm x 500 mm x 0.4 mm
Magnetic field range: 0-20 T


Modified projectile for data transmission


Installed light barriers along the railgun
allow velocity control during launch

Facilities

  • Railgun
    • dynamic (PEGASUS, RAFIRA,
      SR/3-60)
    • static (EMA3)
  • Coil arrangements for homogeneous
    field generation
  • Multi-channel high-speed
    acquisition systems.

Results

  • Projectile dynamics throughout launch
  • Monitoring of magnetic diffusion processes
  • Data transmission from projectile
  • Reduced muzzle velocity dispersion.
