Techniques for Improving Reliability of Air Droppable Sonar Transponder Buoys.

Abstract

An air droppable transponder buoy for use with the LORELI technique has been developed. These units were originally designed to be dropped from altitudes of 150 feet and speeds of 150 kts. The main purpose of the study was to modify the buoys to slow down the rate of descent and to promulgate a clean water entry, thereby reducing the impact forces. Several approaches to the problem were attempted. A small nylon parachute, attached to the float section, was highly successful. (Author)
