    Firing Control Optimization of Impulse Thrusters for Trajectory Correction Projectiles by Min Gao, Yongwei Zhang, Suochang Yang

    Published 2015-01-01
    “…Further simulations show that the impact point dispersion is mainly influenced by the total impulse deployed, and the impulse, number, and firing interval need to be optimized to reduce the impact point dispersion of rockets. Live firing experiments with two trajectory correction rockets indicate that the firing control scheme works effectively.…”
