FEASIBILITY OF THE USE OF WATERBORNE PROPULSION FOR LARGE AIR CUSHION VEHICLES

Propulsive performance predictions are made for large (1,000, 2,000 and 3,000 ton) Air Cushion Vehicles (ACV) with design speeds of 60, 80 and 100 knots. Several gear train arrangements are investigated and a Z drive with dual downshafts and speed reduction in the pod is selected. Minimum required gear envelopes are used to estimate strut pod sizes. The drag of the resultant base vented strut pod system is estimated. The performance of a supercavitating propeller is calculated at hump and design speed. Based on hump and design speed performance, certain craft configurations are selected. (Author)
