In order to study whether the lateral jet technology can suppress the roll damping reverse effect of canard layout configuration missile, this paper conducts CFD based aerodynamic characteristic simulation of canard layout configuration missile. Taking a certain canard layout configuration missile as the research object, the aerodynamic characteristics differences between the missile with and without jet, different aspect ratios, Mach numbers, and attack angles are analyzed. The simulation results show that: at attack angle of 0° and Ma=1.7, the canard layout configuration missile exhibits roll damping reverse effect; As the attack angle increases, the roll damping reverse moment caused by the wash flow from the duck rudder becomes smaller, which is beneficial for roll control of the missile; The lateral jet can significantly suppress the roll damping reverse effect of the missile and improve its roll control ability; As the aspect ratio increases, the roll control ability of the canard layout configuration missile is gradually enhanced. |
