Data Logging Model Rocket Engines on the Shepard Test Stand #OHS

The Shepard Test Stand is a neat way to strap on a model rocket engine and log data from an Arduino. The Shepard Test Stand is on display at the Open Hardware Summit.

The Shepard Test Stand is a test stand for Estes rocket motors. It is named after Alan Shepard, America’s first astronaut, as it is our first test stand. We anticipate using an Arduino board to provide the physical interface between the data collecting computer and the required sensors. This project is the first in a series of projects to develop the required skills for the practice of safe rocket engine operation, and to develop the capability to measure and record data about a rocket engine’s performance. The use of Estes class motors provides a relatively safe environment to learn in before moving to higher powered motors and engines. The ultimate vision is to develop test stands for full scale liquid rocket engines for use in orbital launch systems.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. What is this actually measuring? Does anyone have any documentation on what a shepard test stand is?

  2. The test stand in the video is measureing thrust. You can get a crude approximation of the thrust of a rocket motor using your bathroom scale.

    Or you can use something like a force-sensitive resistor (https://www.adafruit.com/products/166) connected to an arduino and sampled at (small) discrete time steps to get a much better idea what the thrust curve of a given rocket motor looks like.

    Also, kudos to whoever made that video. Their range safty was very nearly textbook perfect. 🙂
