Rapid Thermal Ice Penetration: Feasibility Study for an 'A' Size Sensor.

Abstract

Ocean Systems Research, Inc. has developed a Rapid Thermal Ice penetrator (patent pending) with a demonstrated capability to penetrate thick Arctic ice at rates in excess of 6 feet per minute. This report addresses research and testing performed to determine the feasibility of the concept for rapid delivery of "A" size (4 7/8 inch) environmental sensors through 10 feet of ice under 2 minutes. Two prototype "A" size penetrators were built and successfully tested. A prototype autonomous uprighting device was also built and tested. An analytical model was also developed to provide the capability to predict the affect of various parameters such as payload diameter, weight, etc. on penetrator performance. Three additional payload sizes were evaluated, those being 10, 14, and 21 inch diameters. (MM)
