EFFECTS OF STREAMWISE GAPS, HULL FLOW AND PROPELLER SLIPSTREAM UPON THE AERODYNAMIC CHARACTERISTICS OF A FAMILY OF LOW-ASPECT RATIO, ALL-MOVEABLE CONTROL SURFACES

Abstract

Effects of faired, streamwise gaps upon the free stream characteristics of a family of low-aspect-ratio, all-moveable control surfaces are presented. The family of control surfaces consisted of three aspect ratios (1, 2, and 3) and three sweep angles (0, 11, and 3) and three sweep angles (0, 11 and 22.5 degrees), each having a NACA 0015 airfoil section and a taper ratio of 0.45. Gap effects were also investigated in conjunction with simulated hull effects. Propeller slipstream effects were determined for the minimum gap condition.
