Abstract This article demonstrated the research work on the problem of canard-wing interference of rolling airframe missile via wind tunnel rotating force measuring experiment. According to the result of the wind tunnel experiment, the variation law of rolling rate with different canard-wing setting angle is obtained. The results obtained by four point average method or eight point average method show that the longitudinal aerodynamic problem of rolling airframe missile can be solved with quasi-steady method. The strong interference from down wash under small attack angle condition is one of the main causes which lead to large fluctuation of the longitudinal aerodynamics. The research concluded a rule of the Magnus effect caused by canard-wing interference refer to the rolling rate and change of attack angle. Magnus force and Magnus moment at medium angle of attack have a strong nonlinearity and large absolute value.
