Abstract
In order to investigate the aerodynamics of a loitering munition with a non-circular cross section, a suit of wind tunnel experiment models is designed with a modularized method, and 6-component measuring experiments are conducted under the conditions of Ma=0.4~0.6. The experimental results indicate that the non-circular cross section body can provide a finite lift up to 10 percent at a high attack angle (α≥ 6°). The side force and yaw moment of the loitering munition change linearly with the sideslip angle within little sideslip angles. The loitering munition has good longitudinal, yawing and rolling static stability, and high lift-to-drag ratio. Its aerodynamic parameters have excellent linearization within usable angles of attack.
