| Modeling Approach |
Main combustion chamber and nozzle analysis only. No true power balance calculation. |
Full power balance with fluid analysis starting at pump inlet, through turbine(s), precombustion device(s), valve(s), injectors, main chamber(s), and nozzle(s) |
| # of Input Parameters |
35-40 |
80-150 (depending on cycle modeled) |
| Key Outputs |
Engine thrust, products of combustion, throat & nozzle areas, Isp, weight estimate |
Engine thrust, products of combustion, Isp, weight, reliability, cost, turbo-machinery speeds & power, internal pressures, geometries & areas, and more |
| Execution Time |
1-3 Seconds |
15-120 Seconds |
| Engine Cycles |
Generic staged-combustion, gas-generator, expander, tap-off, and pressure-fed cycles |
Over 20 different flowpaths and variations of staged-combustion, gas-generator, expander, split-expander, tap-off, and pressure-fed designs for "real life" engines |
| Combustion Chemistry |
Frozen and equilibrium flow analysis via minimization of Gibbs Free Energy. Approximately 30 species available in database. |

| Cycle Losses |
Estimation of cycle performance via expert system prediction of analogous efficiencies from historical engines |
Detailed tracking of losses based on results of power balance and fluid flowrate requirements (e.g. gas generator drive gas, etc.), heat transfer losses, etc. |
| Nozzle Analysis |
Rao nozzle analysis with flow divergence loss calculation |

| Engine Weight |
Estimation of upper and lower weight ranges from assessment of major component weights and assumed cycle pressures & flowrates |
Component-level weight analysis using various physics-based, historical, or scaling relationships for engine parts and systems. |
| Engine Cost |
-None - |
Local implementation of the Liquid Rocket Engine Cost Model (LRECM) from NAFCOM. For Government customers only. |
| Engine Reliability |
-None - |
Top-level estimate of engine reliability and safety |
