OpenThrustPy is a software created by members of the Waterloo Rocketry design team at the University of Waterloo. The aim of the project is to provide an accurate thrust curve and apogee prediction for hybrid engine rockets that use NOS as their oxidizer.

- Accurate thrust curve prediction
- Plotter functionality
- Multiple injector flow models
- Easily configurable to different rockets
- More to be added...
- More graphing capabilities
- Fuel regression for more accurate thrust curve
Right now to use the program, you should first generate an RPA table using RPA software found here: http://www.propulsion-analysis.com/index.htm. For our purposes, the free version worked fine. The table should have increments of 10 Psi for the pressure and 0.1 for the OF ratio. After that build and run the program. Input your settings and run the simulation.

This program merely models the thrust and apogee of a rocket using research and data. It can not guarantee the safety or functionality of any rocket being built. We do not take any responsibility for any mistakes, accidents, disasters, etc. that can occur while building or testing your rocket. This program is meant as an aide and should not be used as the sole source of data. Double check all your calculations and always follow proper safety procedures.
