摘要 为了获得鸭式制导炮弹的最佳气动外形参数,建立了鸭式制导炮弹的气动外形参数优化数学模型,以气动性能参数要求为设计依据,提出一种鸭式制导炮弹气动外形参数的优化设计方法。对某鸭式制导炮弹算例的气动外形参数进行优化,结果表明:优化得到的气动外形参数能够保证该弹在飞行过程中稳定性适当,稳定性与操纵性匹配,舵偏角和平衡攻角匹配较好。该方法可作为此类弹箭气动外形设计的工具。 In order to obtain optimal aerodynamic shape parameters of guided projectiles equipped with canards ( GPEC), an optimization model of aerodynamic shape for GPEC is established. An aerodynamic shape optimum design method is proposed for GPEC based on some aerodynamic parameters requirements. By optimizing the aerodynamic shape parameters of an example, the results show that: the GPEC has proper stability with optimal aerodynamic shape; the stability matches the maneuverability very well, and the angle of the canard deflection matches the balance angle of the attack. This method can be used as a powerful tool of the aerodynamic shape design for this kind of projectile.
