Duck Rudder Correction Institutions Flight Characteristic Analysis And Correction Capability Study

With the development of age,modern war asks for the shoot precision of weapon equipment system increasingly high.Since the high shoot precision and the low cost,2D-correction shell has got increasingly attention from the Ministry of National Defense of various countries.To 2-D correction shell,the correction ability of its correction organization has a direct influence on the result of correction and the precision of shoot.This paper makes some 2D rudder correction shell as the object of study,and studying the gas-dynamic character of the correction shell that installing various correction organization and the correction ability of various correction organization.According to the feature of rudder,designing different sizes and different heights for rudder correction organization,processing systematic gas-dynamic simulation for rudder correctional organization of different sizes and different deflecting angles.According to the result of simulation,matching gas-dynamic mathematical equation,including resistance equation lift force equation,overturn moment equation,damping moment equation and so on.The gas-dynamic law and feature of correctional organization getting from gas-dynamic simulation conform to the gas-dynamic law and feature getting from theory.According to the analysis of gas-dynamic simulation for shell,it makes use of kinematic simulation software to analyze and study the technology of decreasing process and control-posture for rudder.Through simulation for decreasing process and control-posture of rudder,it makes correctional shell maintain stable in the process of simulation.Applying the way of dynamic and kinematic united simulation,processing multiple subjects united trajectory dynamic simulation for correctional shell.Through the simulation for kinematic trajectory,confirming the best correctional strategy of rudder correctional organization.According to the best correctional strategy,processing kinematic simulation for correctional ability of rudder correctional organization of different sizes and different deflecting angles,getting the maximum correctional ability of correctional organization.
