Predicted Smooth Water Performance of Several Partial Hydrofoil Supported LVA Configurations

Abstract

The smooth water performance of several partial hydrofoil supported LVA (Landing Vehicle Assault) planing craft configurations is predicted and compared to the predicted resistance of configurations without foils. A smooth water resistance prediction method is developed which accounts for the forces produced by a flapped planing surface. Foils are selected for the LVA and then foil weights are estimated. The results show that the foils can be used to reduce the hump drag by 2,300 lb at a 1,000 lb additional drag penalty at high speed or they can be used to produce marginally better high speed performance at about the same hump drag.
