Analysis and Calculation of Drift of a Terminal Guidance Shell

The drift of a semi-active terminal laser guidance shell is different from that of common shells. On the basis of various typical rigid trajectory models, this paper analyzes the basic characteristics of the drift of one type of terminal guidance shell by simulation and the formative reasons of the drift are discussed. The pivotal elements which have vital effect on the drift value are found, and then the integral time step for calculating the drift is also discussed. Conclusions drawn have the application value for calculating the drift of firing table of terminal guidance shell and have positive instructive significance for trajectory design of a new type of terminal guidance shells.
