Abstract : Ocean System Research, Inc. has developed a Rapid Thermal Ice Penetrator (patent pending) with a demonstrated capability to penetrate thick ice at rates in excess of 6 feet per minute. This report addresses the results of Arctic field testing of 6 ice penetrators complete with autonomous uprighting devices and dummy payloads. The testing proved the overall feasibility of the solid propellant ice penetrator and uprighting device concept to rapidly and autonomously penetrate thick Arctic ice. The actual thickness of ice penetrated was 10 feet, 4 inches in a time of 120 seconds. Hole diameter was approximately 7 inches. (MM)
