Engine Performance Tsfc: RAMJET
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 | tsfc lb lbf hr (lb/lbf-hr) |
|---|---|---|---|
| RAMJET | CRUISE_M3.0_80000FT | Ramjet cruise M3; TSFC degrades rapidly below M2.5, no T/W at SLS | 3.5 |
