What Is A Model Rocket Engine?

Estes model rocket engines are made with black powder and are used to safely launch a model rocket into the air. They are factory-assembled and comply with the safety requirements of the National Association of Rocketry. They are single use and range in power from 1/2A to F sizes. The engine is started using an electrical launch system that is powered by alkaline batteries.

How Does a Model Rocket Engine Work?

1. When the engine is started, it produces thrust and boosts the rocket into the sky.

2. After the propellant is used up, the delay is activated, producing tracking smoke and allowing the rocket to coast.

3. After the delay is used, the ejection charge is activated, which deploys the recovery system, such as a parachute or streamer.
