摘要:
为了提高鸭式布局制导炮弹的弹道控制性能,该文研究了一种通过匹配弹体稳态转速和攻角摆动频率以形成较大有效升力的有控弹道参数设计方法。给出了稳态转速的近似设计公式,提出一种精度较高的弹道法向诱导速度估算公式,并分析了其主要影响因素。仿真结果表明,采用该方法设计稳态转速与法向诱导速度,可在保持稳定飞行的前提下,有效提高制导炮弹的弹道控制能力,不同气动外形参数方案对应的诱导速度值相差可达25%。研究结果可为该类有控弹箭的弹道参数设计提供参考。
Abstract:
To improve the performance of a guided projectile equipped with a pair of canards,an approach of designing the controllable trajectory parameters is investigated here,which matches the projectile’s steady-state spin velocity and frequency of angle of attack to obtain much more effective lift forces.The approximate design formula of the steady-state spin velocity is given.An estimation formula for the normal induced velocity is also proposed,and some main influencing factors are analyzed.The simulation results indicate that the capability of trajectory control can be enhanced effectively under the premise of stable flight by adopting this approach.The difference of induced velocities for different schemes of aerodynamic configurations can reach 25%.These results can provide a useful tool for the design of guided projectiles.
