Model Rocket Parts

I need to know what parts are an engine model rocket and what their function is. Help????

A model rocket engine is very simple compared to something as complex as a brilliant engine space shuttles' fuel and LOX liquid fuel boosters SRB solid.

You essentially take a bottle of something strong but light to form the body (they often resemble cardboard tubes dense) fuel pack, solid in it, enclose it with your rocket together and use a system Ignition by electric spark to start combustion. This created an equal and opposite reaction, the future direction "down" making your rocket go "up".

A homemade rocket fuel can be as simple as a mixture of water, sugar, honey and potassium nitrate (easily obtained from strain disposal of chemicals) in the reports of law.

Visit the links below (in truth, all four, they are quick to read and very informative).

The main parts are the case, nozzle, fuel, late charge ejection.

The casing is the outer tube, usually cardboard.
The nozzle which directs the gases created by burning fuel rocket motor giving the exact amount of thrust. A nozzle that is too wide will dissipate the thrust and the rocket takes off. A nozzle that is too narrow will increase the pressure and the rocket will explode.
The fuel model rocket Estes common style is the black powder which was pressed in a grain of fuel "solid."
The delay is a slow burning mixture of black powder that is used to add extra time between fuel load and eject without adding extra push.
The ejection charge is a fast-burning fuel creates greenhouse gas quickly enough to push the parachute from the rocket.
