BurnSim Main WindowName of the propellantCommon propellant properties, including characterization numbersHere you can specify propellant properties based on chamber pressure. For some propellants, properties change with chamber pressurePropellant NotesC* or Characteristic Exhaust Velocity. This can be calculated in ProPepCharacteristic ISP is simply another representation of C*, aboveBurn Rate Coefficient (A)Burn Rate Coefficient (N)Propellant Density, measured or theoretical from ProPepSpecific Heat Ratio is currently not required, will be used for Startup Transient Simulation in the futureMolar Mass is currently not required, will be used for Startup Transient Simulation in the futureClick this button to add a new propellantClick this button to edit selected propellantClick this button to delete the selected propellantFile MenuAction MenuSettings MenuView MenuHelp MenuGrain Type for specified/highlighted grainsPropellant for specified grain selected from propellant databaseGrain LengthGrain DiameterGrain Core DiameterCore Offset, Fin Thickness, etc - this field will change depending on the type of grain selectedNumber Of Points when a star grain is selected - this field will change depending on the type of grain selected Number Of Points when a star grain is selected - this field will change depending on the type of grain selectedFin Length for finocyl grains - this field will change depending on the type of grain selectedInhibited Ends - select the number of inhibited ends for the grain(s). Can be 0-2.Add Grain - this button adds a grain with the specified propertiesDelete Grain - this button will delete any grains selected in the gridUpdate Grain - this button will update any grains selected in the grid with the properties specified.Grain Up - moves the grain up in the motorGrain Down - moves the grain down in the motorDisplayes motor grains and propertiesImage of the selected grain cross sectionFuture feature where a longitudinal cross section of the motor will be displayedOpen a BSX FileStart a new motor simulationSave current motor diskExport current motor to ENG file for use in flight simulatorsExport current motor data to CSV for consumption in other applicationsRun simulationEnter this tab for nozzle propertiesEnter this tab for editing propellantsOptions for startup transients.
