摘　　要：转速是一对鸭舵控制低旋制导炮弹方案设计中的重要参数。阐述转速在弹丸飞行过程中的变化趋势,采用一对鸭舵控制的低旋尾翼弹为研究对象,建立有控弹道转速模型,根据该模型计算并分析转速对有控弹道特性的影响。数值仿真结果表明,转速对弹丸有控弹道各特性具有不同程度的影响。可为该类弹药的转速设计提供参考。Rotational speed is extremely important in the scheme design of guided projectile with a pair of canard at low roll rate. The change trend of rotational speed during the flight was introduced. Based on study on guided projectile with a pair of canard at low roll rate, the rotational speed model was established. According to the model, the influence of rotational speed on trajectory characteristic was computed and analyzed. The numerical simulation result shows that the rotational speed has effect on controllable trajectory characteristics at different degrees. Some results are useful for further research.
