Under-Ice Surveillance Buoy

US Patent:
6134183, Oct 17, 2000
Filed:
Aug 1, 1990
Appl. No.:
7/566693
Inventors:
Bruce W. Travor - Holland PA
Roger A. Holler - Warminster PA
Donald H. Scott - Warminster PA
Martha E. Snyderwine - Holland PA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
H04B 159
US Classification:
367 4
Abstract:
An air-launched sonobuoy, particularly useful for under-ice surveillance, rries a descent-retardation parachute whose lanyards activate a surface float during descent. Upon impact into an ice region, a slip-rod is jarred loose from the cannister top thus freeing the surface float, and its RF antenna, to remain above the ice while the remainder of the components deploy.
