SUB-ICE TESTS PROMISING FOR EXTENDING SHIPPING SEASON

During the eight-week test program conducted in Michigan with an experimental device, the performance of SUB-ICE (Submerged Ice Cracking Engine) was about equal to theoretical predictions. The test device was a metal barge about 12 ft. wide and 16 ft. long equipped with a single combustion chamber having a volume of about five cu. ft. Pressures inside the chamber reached 400 to 600 psi before release of the combustion gases to form a high-pressure bubble underneath the ice. Working in ice about one-foot thick, the device broke about 100 sq. ft. of ice with each firing.
