PVC Rocket Motor Design Tables (KNSU)

These tables were produced to help those who are interested in building PVC rocket motors avoid CATO events. Each of the motor configurations given should work without a problem if the skillet method is used to produce the propellant, and the outside of each grain is inhibited.

A model was run to calculate maximum chamber pressure and thrust for a variety of motor types. Only those configurations producing chamber pressures between 300 - 400 PSI were used because they provided the most thrust without risk of exceeding the PVC burst pressure.

The PVC pipe that I use is schedule 40, and the diameter of the pipe is given at the top of each table. For clarification, the "Grain ID" just refers to the diameter of the core of a BATES grain.
