HOW A ROCKET WORKS
A rocket moves forward by ejecting gases backward, similar to a leaky balloon.
But instead of air, a rocket ejects hot gases produced by burning a mixture of fuel and oxygen.

HOW TO DESIGN AND BUILD A ROCKET ENGINE
Components of a rocket engine
To build a rocket engine, we need to determine the following dimensions:
- The throat diameter Dt.
- The nozzle exit diameter De.
- The combustion chamber diameter Dc.
- The combustion chamber length Lc.
- The combustion chamber wall thickness Tw
- The water flow gap.
- The diameter of the fuel injection holes (df).
- The diameter of the oxygen injection holes (do).
The calculation formulas can be found in this document:
