Estes Rocket Engines Buyers Guide


Whenever you purchase an Estes rocket or rocket kit, you will find that are certain Estes engines recommended for use with that rocket.

Estes engines are classified by a colour coding scheme that indicates recommended use, and a number system that is laid down by the National Association of Rocketry (NAR) that indicates the impulse, thrust and the time delay to the firing if the ejection charge.

The colours used on Estes rockets are: Green for engines recommended for single stage rockets, Purple for engines recommended for the top stage of a multistage rocket, Red for engines designed to be used as booster engines, and blue for plugged rocket engines.

A typical NAR rocket engine code would look like: A8-3. Wheler ten “A” indicates the pulse in newton seconds that will be produced by the engine, the “8” indicates the average thrust in newtons that the rocket will produce, and the “3” indicates tee seconds between the thrust firing and the ignition of the ejection charge.
