A comment on this question Orange lines coming from rocket engine nozzle? stated in part

The RS-88 is not a full flow engine and there is not a visible bypass exhaust. ... Perhaps they eject the bypass from the preburners into the nozzle.

What engine cycle does this engine use? I would be surprised if it has preburners, but I could not find any information on it. This paper doesn't say. This Rocketdyne press release about its BANTAM precursor says it's based on the Atlas sustainer engine, which was a gas generator cycle, but nothing about the RS-88 itself.

  • $\begingroup$ Incomplete answer, but I found that the wikipedia page on the RS-88 is categorized in "List of engines using the pressure-fed cycle" and this (paywalled) paper about the RS-88 which may help: arc.aiaa.org/doi/abs/10.2514/6.2005-4422 $\endgroup$

  • $\begingroup$ @fasterthanlight Good info. I assumed that at least the abort motor variant would be pressure-fed for reliability, but everything I could find just talked about the thrust chamber. $\endgroup$

    $\begingroup$ Unfortunately, the supporting information for this engine as pressure-fed is a little spotty, citation links do not mention anything about the engine being so. $\endgroup$
