Solid Propellant Internal Ballistics Simulation
Research Rocket Motor design software
Hey folks. Its been long enough. I've got a new beta version of BurnSim ready for download. This is a beta, please contact me to report any bugs . Full change notes below, but a few things worth calling out specifically.
First, units. You can now select from a couple choices on linear, pressure and force units in the Settings menu. I'm a redneck who is firmly stuck in the imperial units world, so I’m looking to those of you more enlightened than I to point out any glaring issues here. Tell me what other unit options I should add.
Second, mass flux. Previously mass flux was only evaluated in the bottom grain of the motor. Now it is evaluated for each grain and the peak mass flux value reported in the UI is the actual peak seen, and also indicates which grain the max was seen. The CSV data export includes mass flux data for each grain throughout the burn.
Third, nozzle erosion. Currently just supports specifying an erosion rate. Again, let me know what you want to here.
Full change notes:
The beta can be downloaded below. This is not a full install, just the .exe. As it's a vanilla .NET application You can download, unzip, and just run. I'll work on a pretty install eventually
PLEASE NOTE, this is a beta. Back up any .bsx files and your propellant database before running this new version. Your propellant database is located in your windows 'documents' folder, titled burnsim3_propellants.xml.https://www.burnsim.com/download/burnsim.18.104.22.168.zip
