【摘要】 建立了便携式防空导弹舵面偏转运动的数学模型,包括正弦偏转运动、不带零位脉冲调宽偏转运动和带零位脉冲调宽偏转运动,推导了相应的等效舵偏角矢量的公式,对比了3种舵面偏转运动对导弹性能的影响,所得结果对导弹设计中舵机的选取有参考价值。更多还原

【Abstract】 The mathematical model of rudder surface deflection of portable antiaircraft missiles is established,including sine deflection,pulse width modulation deflection with null position and pulse width modulation deflection without null position.The formulas of the corresponding equivalent control surface angle vector are deduced.The influence of three rudder surface deflection on missile performance is contrasted.The results are valuable for the selection of actuator in missile design.更多还原
