Engine Performance Tsfc: LOW_BYPASS_TURBOFAN
Aircraft and spacecraft engine performance parameters — thrust-specific fuel consumption (TSFC) and key design metrics by engine class and flight condition. Covers high-bypass turbofan (commercial), ultra-high-bypass (GTF/LEAP), low-bypass turbofan (military), turbojet, turboprop, turboshaft, ramjet, and scramjet engine classes at sea-level-static and cruise conditions.
| engine class | flight condition | bypass ratio (dimensionless) | notes | overall pressure ratio (dimensionless) | thrust weight ratio (dimensionless) | tsfc lb lbf hr (lb/lbf-hr) |
|---|---|---|---|---|---|---|
| LOW_BYPASS_TURBOFAN | SEA_LEVEL_STATIC | 0.6 | Military tactical dry; e.g. F100-PW-229/F110 class dry | 20 | 7.5 | 0.69 |
| LOW_BYPASS_TURBOFAN | SEA_LEVEL_STATIC_AB | 0.6 | Military with afterburner; dry TSFC ~0.7 AB ~2.0 lbf-hr | 20 | 8.5 | 1.95 |
