Abstract

Visualization and some desired measurements of the process of sabot discard of a fin- stabilized projectile has been studied. The paper presents an indirect shadow photographic method with a Fresnei- Lens to obtain high resolution photographs of the projectiieˊs attitude during firing. For the first time, a set of successive photos about the discarding process in the vicinity of the muzzle has been obtained. This provides a reliable test means for the intermediate ballistic study of fin-stabilized sabot discard projectile.

Key words

flow field visualization / ballistic range / high speed photography / intermediate ballistic
