Ice Penetrating Buoy.

A submarine-launched, ice-penetrating sonobuoy is disclosed. The buoy is torpedo-shaped with a collapsible obturator tail-fin section removably attached at the tail-end, standard electronics in a mid-section and an explosive nose cone at the front. Immediately after launch, the tail-fin section expa...

Description
Summary:A submarine-launched, ice-penetrating sonobuoy is disclosed. The buoy is torpedo-shaped with a collapsible obturator tail-fin section removably attached at the tail-end, standard electronics in a mid-section and an explosive nose cone at the front. Immediately after launch, the tail-fin section expands to exert a drag on the buoy to halt any forward motion. The tail-fin section is discarded and the nose cone and mid-section portion rise until the nose impacts the underside of the ice. Upon impact, a pre-selected shape charge ruptures the ice and an a spring-antenna, connected to the midsection, is raised through the hole. Supersedes PAT-APPL-53 763-93.
