How do conventional rockets work?
Rocket propellants are the fuels and the oxidizers carried by the rocket for propulsion. There are a variety of different fuels and oxidizers because they all have some tradeoffs. For example, the cryogenic propellants have a better specific impulse but they are harder to handle and tend to have low densities. A higher specific impulse helps by increasing the efficiency of the thrust per amount fuel spent. However there is a tradeoff in terms of difficulty in handling and the low densities which require a larger tank
|Propellant||Chemical Formula||Molar Mass||Melting/ Freezing (K)||Boiling (K)||Heat of Vapor-ization (kJ/kg)||Specific Heat (cal/kgK)||Specific Gravity||Viscos-ity (centi-poise)|
|RP-1||hydrocarbon CH1.97||~175||225||460- 540||246||0.45||0.58||0.21|
