Effects of Mid-Chord Flaps on the Ventilation and Force Characteristics of a Surface-Piercing Hydrofoil Strut,
Abstract
Ventilation and side force characteristics of a NACA 16-012 strut with span-wise mid-chord flaps attached from 0.5 to 0.7 chord were determined. This strut configuration represented a strut system with retractable mid-chord flaps in the extended mode. Experimental results showed that such a strut system exhibits the advantage of a streamline strut at preventilation speeds (low drag) and the advantage of a blunt-based strut at ventilation/post-ventilation speeds (no side force reversal).
