The Research On Rolling Characteris-Tics Of Canard-Controlled Missiles

Canard-controlled missile is applied broadly in tactical missile because of its high maneuverability、good manipulation performance、rapid Response and easy to fix etc. The capability of canard missile is mainly restricted in rolling controll characteristics. The rolling moments could be reduced, even the phenomenon of anti-effect has disappeared completely, because noticeable reverse rolling moment is induced by the canards’ down wash when the canard have roll command deflection.In this thesis, to investigate the rolling control characteristics on canard-controlled missile with fixed-tail, a numerical simulation method was conducted. To analyse influence on the rolling aerodynamic moments by configurations parameter of the canard-controlled missile. To investigate influence on characteristics of fin find out the reasons that strengthen rolling control characteristics and reduce rolling moments induced by the canard’s downwash. To investigate characteristics of wing find out resources that wing rolling moments at unsymmetrical state and reduce rolling moments by downwash from fin; To investigate influence on distance between fin and wing,base on being satisfied with capability,the rolling moments of canard-controlled missile with fixed-tail change with distance between fin and wing.To contrapose these laws that fin parameter、wing parameter and distance between fin and wing effect rolling characteristics of canard-controlled missile with fixed-tail by numberical simulation. To connect with pitching’s characteristics of the kind missile,and design a outline of accord with technical and tactical target, then complete force test of missile and analyse experiment result. To choose proper configuration of fin and wing,to match appropriate distance between fin and wing. The canard-controlled missile with fixed-tail can controll rolling moment and realize technical and tactical target.The research achievement can offer for gist to design canard-controll missile and improve capability, and directly apply engineering and practice.
