Preparation and Characterization of Slush Hydrogen and Nitrogen Gels
Because of the high specific impulse achieved with liquid hydrogen in combination with various oxidizers (liquid oxygen and liquid fluorine, for example);, it has become an important rocket fuel in spite of the problems associated with its use. Some of these problems or disadvantages are: (1) low density, (2) temperature stratification, (3) short holding time due to the low latent heat of hydrogen, (4) hazards associated with the high vent rates, and (5) unstable flight conditions caused by sloshing of the liquid in the fuel tank.
