We created a Jupyter Notebook to calculate parameters for the injector.
| Inner nitrous orifice angle | 14º |
| Middle nitrous orifice angle | 18º |
| Ethanol orifice angle | 46º |
| Nitrous orifice distance | 0.27 inches |
| Middle nitrous orifice to ethanol orifice distance | 0.64 inches |
| Height of faceplate for oxidizer | 0.53 inches |
| Height of faceplate for fuel | 0.17 inches |
| Oxidizer annulus height | 0.24 inches |
| Fuel annulus height | 0.10 inches |
Using Huzel and Huang (pp. 144-148), we calculated chamber lengths to avoid to minimize the risk of longitudinal instability. These lengths are 125, 127, and 172 inches.
