Rocketry

For a few summers I have been involved in sugar rocketry, building and launching rockets through my own research and learning. Sugar rocketry uses a mixture of sugar and an oxidizer, such as potassium nitrate, as a solid fuel packed into a tube to create an engine for launch.

Model

Scratch-Built Rocket Body

I built this model rocket from scratch to launch and test my sugar rocket designs. It includes a nose cone, body tube, fins for stability, and a recovery system designed to bring the rocket safely back down after flight.

Engine

Sugar Rocket Motor

The engine provides the thrust needed for launch. It uses a sugar-based propellant mixture, and in this setup black powder sits above delay fuel to deploy the parachute near the peak of the flight.

  1. Sugar
    • Acts as the fuel in the propellant mix.
    • Burns when combined with the oxidizer.
    • Helps create the gas that produces thrust.
  2. Potassium nitrate
    • Works as the oxidizer in the engine.
    • Supplies oxygen so the fuel can burn quickly.
    • Is one of the most common ingredients in sugar rocketry.
  3. Delay fuel
    • Burns more slowly after the main thrust phase.
    • Creates a timed gap before recovery deployment.
    • Helps the parachute open closer to apogee.
  4. Black powder
    • Sits near the top of the motor in this setup.
    • Provides the charge to eject the parachute.
    • Is used for recovery, not for the main thrust.

Guide

Best Video Resource

This is the most useful guide I have found for learning how sugar rockets are made. It has been the best video reference I have used while researching the process and understanding the overall build.

Launch Data

Rocket Launch Tableau Dashboard

This embedded Tableau dashboard appears to compare rocket launch activity by top agency. I included it as a useful outside visualization because it connects well to the broader topic of rocketry and shows how launch data can be organized interactively.
