鸭式布局防空炮弹的鸭舵设计优化

为提高防空有控炮弹的弹道性能,以一对鸭舵控制的防空弹道修正弹为对象,阐述了系统工作原理与鸭舵控制方式,在全指令控制信号及弹体稳态飞行条件下,研究了由鸭舵偏转产生的弹道法向修正速度,给出了精度较好的估算公式。由此提出一个以鸭舵气动外形参数为设计变量的弹道修正能力综合优化设计模型,并进行了数值仿真。仿真结果表明,采用该模型对鸭舵气动外形参数进行综合优化设计,能够有效提高鸭式布局防空炮弹的弹道控制能力,为该类有控炮弹的鸭舵气动外形参数设计提供了参考。

Optimum Design of Canard Parameters of Air Defense Trajectory Correction Projectile Equipped with a Pair of Canard Surfaces

To improve the performance of air defense trajectory correction projectile (ADTCP), the operating principle of system and the canard control mode were described briefly for the projectile equipped with a pair of canard surfaces. The trajectory normal correction velocity due to the deflection of canard surfaces under the conditions of full command control signal and steady-state flight was investigated. An estimation formula was given, and an optimum design model of trajectory correction capability was proposed by taking the canard aerodynamic shape parameters as design variables. The simulation was conducted. The result show that the control performance of ADTCP can be enhanced effectively by using the optimum design, and the approach provides a reference for the design of canard shape parameters of ADTCP.
