ABSTRACT:
There is disclosing a novel dynamic seal for a projectile having an inter chamber for cylindrical canisters of discrete liquids wherein a circumferential gap is formed between adjacent canisters in said chamber. The seal comprises a ring member which is formed of an elastomeric material and possesses an annular chamber containing a deformable substance of relatively high density. The ring member is juxtaposed about said circumferential gap so that by the centrifugal force of the spinning projectile the ring member is deformed and forced radially against said gap, thereby sealing and preventing leakage of liquid through said gap.
