Surely the Isp, i.e. thrust per propellant weight flow rate, would have to be much higher for that air turborocket? 250s is not that great already for a rocket

Surely the Isp, i.e. thrust per propellant weight flow rate, would have to be much higher for that air turborocket? 250s is not that great already for a rocket that has to carry all of the propellant; the big advantage of an airbreathing engine is that only a fraction of the accelerated massflow is propellant.
- msandford 5y agoI believe that's the ISP of the initial reaction that makes a hydrogen rich gas that you feed into your air breathing thing. That's how it reads to me anyhow. You'll likely get extra ISP from the hydrogen/air combustion too.
- pfdietz 5y agoThat's correct; it was the Isp of that combination if just used in an ordinary rocket engine, not an airbreathing engine.
