BurnSim – Solid Propellant Internal Ballistics Simulation Research Rocket Motor design software

BurnSim is a solid rocket steady-state ballistic simulation software package for the Windows platform. In a nutshell, input your motor, nozzle and propellant characteristics and BurnSim calculates the Kn through the burn and predicts estimated chamber pressure and motor performance. Once your motor design is in BurnSim, you can tweak the parameters such as nozzle diameter or grain core diameter and instantly see how the Kn, chamber pressure, and motor thrust is affected. BurnSim will also optimize your nozzle design.

Motor designs in BurnSim can be saved and recalled for later use. In addition, test data can be imported and graphed alongside simulation data to compare sims to results. BurnSim allows you to make notes about your propellants and motor designs, all saved in one convenient location.

Once you’re happy with the your motor design, BurnSim can then export a .ENG file for use in RockSim, wRasp or other rocket flight simulators. You may also export the data to a text file (comma delimited) for use in virtually any system. You can estimate your motor’s performance and rocket’s flight before you even cast a grain!
