Race 2 Space 2026: Lúin of Celtchar

Overview

This repository contains some notebooks for using the python wrapper for NASA CEA

Notebooks

01_single_problem.ipynb

This demonstrates setting up propellants and some basic parameters, running a single rocket problem, and accessing the results.

02_phi.ipynb

This runs multiple problems across a range of phi values to demonstrate looping and accumulating results, plus some graphing techniques such as multiple result parameters across a shared axis of the independent variable (phi in this case).

03_2_vars.ipynb

This runs problems across 2 independent variables, pivot tables the results and projects onto both static and interactive graphs.

Setup notes

Was difficult to get going on linux Main bit is compiling the dan_cea for linux

gfortran -o Dan_CEA2 dan_cea2.f

and telling the wrapper to look there with

import os
os.environ["CEA_USE_SITE_PACKAGES"] = '1'
from CEA_Wrap import Fuel, Oxidizer, RocketProblem
