V1.0 Size Calculation (150 N)
December 20, 2025
This entry records the basic size calculation for a 150 N thrust, 10 bar chamber pressure, GOX/ethanol engine. This is a very small size, and we are still evaluating its manufacturing feasibility.
Assumptions
- Thrust $F=150 N$
- Chamber pressure $p_c=10bar / 1.0 MPa / 145 psia$
- Propellants: GOX/ethanol
- Performance: use CEA results as thermo-chem input
Report Links
- CEA report and structural report are collected here
