Explanation

Molecular weight 44.013, colorless, sweet smell, freezing point -90.81 ° C, boiling point 88.47 ° C, gas density (1.3kPa, 15 ° C) 1.874kg/m3, steam relative density (air=1) 1.530, liquid relative density 1.23 (water=1), saturated vapor pressure (20 ° C) 5.150MPa, which can be used for cold air propulsion, unit propulsion, bipropellant propulsion, solid liquid propulsion and electric propulsion. nitrous oxide can be used in multi-mode propulsion system, non-toxic, safe, good compatibility of materials, low injection cost, self pressurization, high storage density, long-term storage in space, wide source, dual-use, cheap, can be used as oxygen source and cold source. The specific impulse of nitrous oxide monopropellant is low; Heating is required during startup and there is power consumption; High pressure insulated containers are required for storage, transportation, and use; Narrow liquid range.
