Abstract

Aircraft with a blunt-nosed slender body configuration exhibit free-to-roll motion during maneuvering flight. The separation vortex on the forebody and the wing parameters are the two key factors affecting this motion. A blunt-nosed slender body configuration normally includes multiple sets of wings, which enhances the complexity of the roll motion. The strips, narrow wings, and tail rudders are installed at different axial locations on the blunt-nosed body to study the influence of wings on the roll motion. Wind tunnel experiments are conducted to investigate the motion at Reynolds number Re_D = 1.54
