Overall efficiencies range from 30 to 80 percent, depending on the fuel and oxidizer and on the basis for the calculation. |
Currently, most rockets use a solid or liquid propellant that relies on a chemical reaction between fuel and oxidizer for thrust. |
Let that dry for an elegant metal finish, or apply the patina topcoat or rapid rust oxidizer for a unique variety of aged finishes. |
It is a very powerful acidic oxidizer which can ignite or explode on contact with many materials. |
Rocket propellants come in two parts, fuel and oxidizer, which work together to keep an engine burning. |
A third type, called a hybrid, combines a solid fuel with a liquid oxidizer. |
