The Aerodynamic Characteristics of Wrap-Around Fins, Including Fold Angle at Mach Numbers from 0.5 to 1.3

Abstract

An experimental investigation was conducted in the transonic wind tunnel to study the aerodynamic characteristics of wrap-around fins. Wrap-around fins with leading edge sweep angle on straight and step down bodies 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 1.3 at angles of attack up to 14 degrees and roll angles from 0 to 67.5 degrees. The results of the test are presented in plotted form for the main balance and all four fin balances.
