Air Cushion Icebreaking Platforms: innovative approaches to ice destruction and parameter optimisation

This article discusses innovative approaches to icebreaking and the optimisation parameters of Air Cushion Icebreaking Platforms (AC IBP). The study is conducted in the context of the need to ensure year-round navigation on northern rivers and potentially support Arctic expeditions. The primary method of icebreaking involves creating an air cavity under the ice, causing it to break under its own weight. This research employs both theoretical mathematical models and experimental data to determine the optimal parameters of AC IBP, such as the length and width of the air cushion, cushion pressure, and the power of the lifting complex. The results demonstrate the high efficiency of AC IBP in breaking ice up to 400 mm thick, exceeding design specifications. Optimising the AC IBP parameters helps to achieve minimal energy consumption with maximum efficiency. Experimental tests confirm the reliability of the design and compliance with project specifications. Further research aims to improve the AC IBP design and expand its operational conditions.
