Engine Performance Tsfc: TURBOPROP
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) |
|---|---|---|---|---|
| TURBOPROP | CRUISE_20000FT | Cruise 20000 ft typical turboprop; e.g. PW127/TPE331 | 12 | 0.42 |
| TURBOPROP | SEA_LEVEL_STATIC | Converted to equivalent TSFC basis (lb/shp-hr = ~0.50); PT6A class | 10 | 0.5 |
