BurnSim is free software for simulating solid rocket motors, built to be as simple to use as possible while staying accurate for real motor designs. This wiki documents BurnSim 4, the current cross-platform (Windows, Mac, Linux) rewrite of BurnSim, and covers general topics related to experimental solid propellant motors: propellant characterization, motor testing, data acquisition, and more.
Still running BurnSim 3? Its interface differs substantially from what's shown below - see the BurnSim 3 documentation instead.
