对于很高速度的水下导弹(如水下射弹),采用水下喷气发动机是最合适的。这种水下冲压发动机似乎可更适合用于较远射程的导弹。针对这类应用,本文研究了双组份自燃反应的液体燃料三乙基铝(TEA)。利用对烟火混合物的热力学特性进行计算的程序,进行计算机计算,从而得到理论比冲。使用TEA的冲压发动机的可行性需要在静状点火试验中证明。因而已研究出一种特殊的喷射装置。 For very high speed underwater missiles (such as underwater projectiles), underwater jet engines are most suitable. This underwater ramjet seems to be more suitable for longer-range missiles. For such applications, this paper studies the two-component self-ignition liquid fuel triethylaluminum (TEA). The calculation of the thermodynamic properties of the pyrotechnic mixture is carried out using computer calculations to obtain the theoretical specific impulse. The feasibility of using a ramjet engine needs to be demonstrated in the static ignition test. Therefore, a special spraying device has been developed.
