<p>Pat123: added HCMP to Apps</p> <hr /> <div>The certain members of the spudding community have written computer programs pertaining to spudguns:<br /> <br /> <br /> ==the [[GGDT|Gas Gun Design Tool]]==<br /> 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 [http://www.thehalls-in-bfe.com/GGDT/].<br /> <br /> 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.<br /> <br /> ==[[CALM]]==<br /> Standing for &lt;b&gt;Compressed Air Launcher Model&lt;/b&gt; 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.<br /> <br /> CALM can be downloaded at http://www.qsl.net/wb6zqz/calm.html .<br /> <br /> ==[[EVBEC]]==<br /> EVBEC stands for Energy &amp; Volume Based Estimator for Combinations. Written by boilingleadbath, it is based on [http://www.burntlatke.com Latke's] chamber:barrel test data.<br /> <br /> Hosted on spudfiles, it is free to [http://www.spudfiles.com/forums/viewtopic.php?t=1212&amp; download] and use.<br /> <br /> ==[[SpudTool]]==<br /> A great spudding tool made by Boogieman.

[http://www.spudfiles.com/uploader/uploadFiles/ProMeterSuite.zip Download]<br /> <br /> ==[[Unit Converters]]==<br /> [http://www.digitaldutch.com/unitconverter/ UnitConverter] is a handy online converter. You can convert metric pipe sizes to U.S. sizes, pressure, volume, energy and many other kinds of units. Put a shortcut in your web browser and you're never more than a second or two away from converting, for example, cubic inches to liters.<br /> <br /> [http://joshmadison.com/software/convert/ Convert] is a downloadable windows application with capabilities similar to UnitConverter. Put a shortcut on your start bar and you're never more than a second or two away from converting, for example, cubic inches to liters.<br /> <br /> ==[[Launcher Range Calculator]]==<br /> Predicts ballistic trajectory accurately taking into account both atmospheric and ballistic variables.
