Research on Influence Factors of Trajectory Correction Interval for Cross Canard Configuration

Abstract

Correcting law is an important component for two-dimensional trajectory correction technology of spin-stabilized projectile, and it is a key issue to acquire the ideal circular error probability (CEP) of impact points by reasonable correction interval. This paper focuses on the influence factors to determine the correction interval, correction interval determining method based on transient duration of ballistic dynamic process is proposed. The optimum correction interval can be obtained by comprehensive consideration of initial launch parameters, dynamic transient duration and on-board electronics response time. Monte Carlo experiments are performed on square-crossing fixed-cant canard configuration of 155mm spin-stabilized projectile to verify the proposed approach.
