AERODYNAMICS OF STRAKE-WING INTERACTIONS

This paper reports on an experimental investigation where the longitudinal aerodynamic characteristics were determined up to high angles of attack for configurations employing parametric variations in strake span and wing sweep and includes correlations with theory. The investigation included both component and complete configuration studies to provide information for the analysis of interaction effects. Comparisons between strake-wing and high canard-wing configurations demonstrate the strake wing to develop higher lift coefficients than did the canard wing due to enhanced interference effects. Correlations with theory demonstrate the suction analogy to be a useful method for estimating the effects of vortex flow aerodynamics on both component and total forces and moments. © 1979 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
