摘　　要：通过对国内外引信用涡轮发电机转速控制技术方案的分析,提出利用形状记忆合金新型材料,实现在变化的气流条件下,控制涡轮发电机转速的机构方案——涡轮发电机可调喷管机构。该机构利用变化的气流速度对进气道管壁气动加热温度的改变,利用形状记忆合金双程驱动器的感温特性,实现对进气道出口面积的调整,进而控制流入涡轮发电机的气流动量,实现对涡轮发电机转速的控制。该项研究成果还可应用于火箭发动机喷管的自适应调节,实现发动机推力调整的目的。Based on the analysis of fuze turbine alternator speed control mechanism schemes at home and abroad,a turbine alternator adjustable nozzle mechanism scheme using the new material of shape memory alloy（SMA） was brought forward to fulfill the control of turbine alternator speed under altering airstream condition.As the aerodynamic heat temperature of the entry pipe wall varies with the flow speed change,the sensitivity to temperature of SMA is used to adjust the exit area of the entry pipe,then control the flow momentum into the turbine alternator,so that the turbine alternator speed is under control.The research result also could be applied in the adapting adjustment of the rocket engine nozzle to fulfill the engine thrust adjustment.
