The Aerodynamic Characteristics of Wrap-Around Fins, Including Fold Angle at Mach Numbers from 0.5 to 3.0

Abstract

An experimental investigation was conducted in the McDonnell Douglas Aerophysics Laboratory 4-foot trisonic wind tunnel to study the aerodynamic characteristics of wrap around fins. Wrap around fins with leading edge sweep angle and exposed semi-span variations were tested. One unswept fin was tested simulating various opening angles from 10 degrees beyond fully open to a folding angle of 112.5 degrees. Force and moment data were obtained at Mach Numbers from 0.5 to 3.0 at angles of attack up to 14 degrees and roll angles from 0 to 45 degrees. The complete results of this test are presented in plotted form for the main balance and all four fin balances.
