I didn’t see much discussion on potential efficiency gains in that thread.
A launcher would aim for higher altitudes than an airplane, so the question of maintaining efficiency the whole way becomes much more important.
I suspect this kind of engine would need something like a single-use aluminium air battery to make sense though. You could get really high energy density that way. Power density might be a challenge though.
- Tuna-Fish 3y agoI would assume they just use a generator on the shaft? This would be dramatically more weight-efficient than any kind of batteries.

The key insight is to use electric motors to drive a compressor. That way we can make it spin at any speed, allowing it to "adapt" to it's airspeed and combustion cycle."
