Hi all!
I'm pleased to announce I've released the first version of my new motor
design tool called CoreBurner. I tend to build 'core burning' grain motors
as the grain protects the casing, but I've never had a design tool that I
felt was comparable to the bates grain simulation programs out there. While
you can use a bates grain simulator with the ends inhibited and a single
grain to get close, I wanted something that got me an accurate mathematical
model of what's going on. I've also done a lot of nozzleless motors over
the years and that's another configuration that no parametric tool
utilizing a mathematical model of a nozzleless motor to predict performance
exists for (other than my crude tool from a couple years ago which was very
limited in it's ability to work with different propellants, L over D
ratios, etc. the way it was setup), so CoreBurner supports nozzleless
motors of any size with any propellant as well.
A friend of mine intends to make a java script implementation for a web
based version of this at some point, but for now this is an excel based
tool. I hope some of you will find it as useful as I do. [image: 📈][image:

Please let me know if there's any features you'd like to see implemented in
future releases and I'll see what I can do. I will be adding cored end
burners at some point since I've had some issues with the limitations of
other tools out there with that configuration as well, but I'm not sure
when I'll get around to that.
