Looks like it, Robyn.
The Scimitar doesn't have a rocket-cycle. I don't really understand what the function of a pre-burner would be without a rocket cycle.
Not sure about those heat exchangers.
Yeah me neither. Especially with the HX3 mentioned on the Scimitar. I assume it's function is different because on the SABRE, HX3 was part of the rocket-cycle, which the Scimitar lacks.
