I developed a spreadsheet to compare different fuel types at different pressures, mixture rates, and flow rates. During the duration of flight, the atmospheric conditions at altitude were considered, change in mass accounted for, and engine performance applied to model flight performance. The results were what I used when determining the requirements for the Gizzard-1 Engine.

This analysis was performed specifically to provide a 1d flight simulation, similar but lighter than what OpenRocket and RockSim do, while also allowing cross-comparison of different liquid motors - a functionality not tied to either of the regularly utilized software.
