Model Explanations

Aspire Space Model (AKA Main Model)

Solomon Model

The model is named after the author of a paper about two phase injector flow. The code was adapted from the MatLab code provided within the paper. The main tweak is that instead of assuming a constant atmospheric pressure after the injector, the pressure changes over time based on the combustion pressure. This pressure is found through some rocketry equations and data from the RPA software. The paper can be found here in the digital commons library. The following citation is also provided:
