The certain members of the spudding community have written computer programs pertaining to spudguns:
Contents
the Gas Gun Design Tool
Written by David Hall (D_hall of the SGTC), it is the most commonly used program to predict pneumatic cannon performance, and is free for the download at Hall's website.
Accuracy of the predictions is typically within 5-10% of the actual value, although there has not been much testing of very long where the (unaccounted for) flow resistance due to barrel length is significant, or very high pressure launchers where the non-modeled liquefaction of the propeller gas(ses) may take place.
CALM
Standing for Compressed Air Launcher Model this is a Pneumatic Launcher simulator program by AKB of the SGTC. Since it is written in the Python programming language you can read the code and see how it works. It is not graphical, but produces tables of pressure, velocity, height, etc.
CALM can be downloaded at http://www.qsl.net/wb6zqz/calm.html .
EVBEC
EVBEC stands for Energy & Volume Based Estimator for Combinations. Written by boilingleadbath, it is based on Latke's chamber:barrel test data.
SpudTool
A great spudding tool made by Boogieman. Click here to try it out
ProMeterSuite
Spud Calculators galore. Requires Microsoft Excel. Download
Unit Converter
I just found this a long time ago and is really handy when converting metric pipe sizes to U.S. sizes. Download
Launcher Range Calculator
Predicts ballistic trajectory accurately taking into account both atmospheric and ballistic variables. Download
Other Calculators
