Engines · Jet
Six air-breathing engines, from the airliner's turbofan to the hypersonic scramjet — each solved live with the real ideal-cycle thermodynamics, so you can see exactly why each one owns its slice of the flight envelope.
The original jet — all thrust from one hot, fast core stream. Design envelope: Mach 0–3.
Open demo →LiveA big fan does most of the work — quiet, efficient, everywhere. Design envelope: Mach 0–1.
Open demo →LiveA gas turbine geared to a propeller — bypass ratio taken to the limit. Design envelope: Mach 0.1–0.7.
Open demo →LiveAll output as raw shaft power — no thrust, no propeller. Design envelope: Mach 0–0.4.
Open demo →LiveNo moving parts — ram compression alone, but only once you’re fast. Design envelope: Mach 1–5.
Open demo →LiveA ramjet that burns supersonically — the key to hypersonic flight. Design envelope: Mach 4–12.
