NOTES ON ICEBREAKING WITH AIR CUSHION VEHICLES
A theoretical approach to the icebreaking of floating ice plates by means of air cushion vehicles (ACVs) is presented. The method makes use of currently available analytical equations for determining the response of floating ice sheets to moving ACVs. Deflection and strain values of the ice under a load moving at constant speed are maximized when the speed is equal to a critical value, a function of craft length and water depth. When subjected to moving loads with speeds of less than half the critical value, the ice sheet response is similar to that in reaction to a stationary load. Examples of the calculation procedures are given, and the results compare favorably with published data.
