Abstract:

The report deals with the analytical investigation of the thrust agumentation, lift forces and mixing properties of a two-phase flow propulsionlift system which has application to Air Cushion Vehicles ACV and Surface Effect Ships SES. The results of Water-Augmented Vehicles WAVE computer program investigations show that significant thrust augmentation can be obtained by the injection of spray inherently produced through the interaction of ACVs and SESs with water surfaces. In addition propulsive efficiencies of 60 can be obtained with relatively quiet operation. The flow model I analysis conducted was based on a modified, one-dimensional duct flow and considered the transverse injection of spray and cushion air into the propulsion duct. Flow pressure losses, leakage of propulsion air from the propulsion duct, droplet breakup and the penetration of spray droplets into the propulsion duct where taken into account.
