BurnSim Description

BurnSim is a solid rocket steady-state ballistic simulation software packag. 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. Get BurnSim and take it for a spin to see what it can actually do for you! Main features: Supports the following grain configurations in any number and combination: BATES grains with 0-2 restricted ends End burning grains (defined as BATES grain with zero diameter core) Moon or Offset Core D Grains C-Slot Finocyl Star X-Core Different propellant types can be specified for each grain Instantly see a graph of Kn, chamber pressure, thrust, and see how it changes when you change motor attributes. Graph Mass Flux over the burn, a value that can be used to monitor erosive burning Import test data and graph it along side simulations Save your motor designs and propellant characteristics, as well as notes and imported test data Export predicted motor performance into .eng files for use in Rocksim or wRasp Export predicted motor performance into .csv files (comma delimited text files) for use Excel or any other program. Thrust estimations based on nozzle geometry Optimize your nozzle design for maximum performance. Propellants can be defined with characterization data that changes over varied pressure ranges
