摘　　要：以3,4-二氨基呋咱(DAF)部分取代高氯酸氨制备低特征信号富燃料推进剂。采用最小自由能法计算推进剂的能量性能。结果显示,推进剂的比冲随DAF含量的增加而提高,含15%DAF的推进剂比冲可达7 969.636 N.s/kg。该系列推进剂的红外和可见光信号衰减随着DAF含量增加呈现先降低后增加的趋势,含10%DAF推进剂的红外和可见光信号衰减最小,红外和可见光透过率分别达到78.1%和70.9%。The fuel-rich propellants with low characteristic signal containing 3,4-diamino-furazan （DAF） were prepared. The energy properties and characteristic signal of the propellants were analyzed. The results show that the specific impulse becomes higher with more content of DAF in the propellant. The highest specific impulse of the propellant is about 7 969. 636 N·s/kg when the content of DAF is 15%. The signal transmittance first increases as the content of DAF in the propellant increases, then decrease. The propellant containing 10% DAF involves the lowest characteristic signal with visible light transmittance 78.1% and infrared transmittance 70.9% respectively.
