Model Tests in Ice to Confirm Effectiveness of the 140-Foot WYTM Air Bubbler System.

Abstract

A 1/24th scale model of the 150 FT. WYTM was equipped with an air bubbler system. The bubbler system was operated at various flow rates from no flow to twice the nominal system capacity. Tests were performed in both solid ice and brash to determine the effectiveness of the bubbler system in reducing the power required to transit ice fields. In all cases, a flow was found which reduced the total power from that required for a ship without the air system. This model test formed the basis for designing the air bubbler system for the Coast Guard 140' class of icebreaking tugs. (Author)
