Engine Performance Tsfc: HIGH_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 | notes | overall pressure ratio (dimensionless) | tsfc lb lbf hr (lb/lbf-hr) |
|---|---|---|---|---|
| HIGH_BYPASS_TURBOFAN | CLIMB_10000FT | Climb power setting ~10000 ft | 40 | 0.4 |
| HIGH_BYPASS_TURBOFAN | CRUISE_35000FT_M0.80 | Long-haul cruise typical; BPR 8-12 | 38 | 0.52 |
| HIGH_BYPASS_TURBOFAN | CRUISE_35000FT_M0.85 | Cruise condition 35000 ft M0.85 typical commercial | 40 | 0.55 |
