PyBurn

A Hybrid Rocket Motor Propulsion Model - Python

• Combust.py : The primary run script, where all experimental / geometrical parameters are input
• Thermo.py : Thermodynamical + some thermochemical calculations to determine combustion parameters
• Nozzle.py : Isentropic flow through nozzles based on [5]. Determines thrust and efficiencies
• Properties.py : Approximations of key thermochemical variables with respect to oxidizer/fuel ratio. Taken from [2], Fig 4
• Inject.py : An orifice-plate model based injector flow rate calculator

Currently, only supports analysis of ABS/N2O rocket motors.

To run, call python Combust.py
