Simulation And Research On Exterior Ballistic Of Certain Medium Caliber Command Guidance Antimissile Ammunition

This paper taking certain medium caliber command guidance antimissile ammunition as research object, according to operational purpose, combining the detecting guidance equipment of existing warships as well as the flight features of air attack objective, designs the operational mode and guidance control principle of the ammunition and makes a research on command guidance antimissile technique engineering application. Based on the aerodynamic force test result and exterior ballistic data from actual flying test, setting up six free degree exterior ballistic mathematics model, through introducing the control model of each sector, simulating the feasibility of the radar command guidance exterior ballistic plan, the value of control force of actuator, the selection of starting control point, also the influence of all kinds of control parameters in control strategy on exterior ballistic correction capability, establishes the basic indexes of projectile body control parameter and optimizes the service performance of ammunition structure and control principle. In the end, the paper analyzes the error source which influences the control precision and the mathematical model of error source, reasonably combines different kinds of exterior trajectory disturbance and accuracy error source of control command, analyzing the influence of practical hitting accuracy of the ammunition and getting the major factors and secondary factors influencing the hitting accuracy, supplies theory gist for certain medium caliber command guidance antimissile ammunition index optimization and evaluation of operational performance.
