HYDROFOIL STRUT ARRAY HYDRODYNAMICS

The hydrodynamic problem of calculating the potential flow characteristics of a hydrofoil atteched to a strut is discussed. A computerized-numerical method based on linear lifting surface theory is used to calculate the lift, induced drag and pressure distribution of an unswept, untapered, planar hydrofoil attached to a symmetrical strut with or without an axisymmetric nacelle in the mid-wing position at the junction of the foil and strut. Particular attention is given to the junction of the foil with the strut or nacelle. One of the several practical results of the program is the ability to calculate the cavitation inception speed of the complete hydrofoil system.
