| ROCKET ENGINE COMPONENTS | ||
The most common and well-known rocket engines are chemical engines. A chemical engine is an engine that mixes fuel and oxidizer, combusts them, and uses the resultant energy for mechanical or propulsive use. A car engine is a very common example of a chemical engine. It takes fuel (gas) from the tank and mixes it with an oxidizer, (atmospheric air) and combusts them in the piston chamber. Propulsive force is the ultimate result when the energy of this chemical process is delivered mechanically to the road by the wheels through the transmission system. |
