    Abstract
  • The work was done for the research of interior ballistic. A wide range fiber probe (depth of field is 13 m) was designed for measuring the motion history of projectile launched by a 32 mm two-stage light gas gun. The projectile velocity was measured by using a VISAR with velocity per fringe 100 m/s. The obtained result shows the projectile reaches a velocity of 3 960 m/s at the distance of 11.3 m, which is well consistent with the result from the magnetic measurement. The acceleration history of projectile was also obtained by differentiating the velocity profile. This work proved that the VISAR can been used in the interior ballistic research.
