Few more angles. Apart from the ATM and truss most of the rest is placeholder.

@ParkerFromMars 2) The gas generator is fed through bleed from the LOX and LH2 lines. Runs to the LH2 turbo impeller and then LOX, then dumped through the nozzle extension. White sphere provides Helium for same path for start sequence. Runs both sides from LH2turbo.

@ParkerFromMars 1) If u can excuse the terrible writing. Its a fairly simple design.

Right is primary flow. LH2 goes to upper nozzle regen cooling and then chamber. LOX goes to top of chamber and does some transpiration cooling.

4/5 Finally the Rocketdyne RS30. A highly restartable small RL10 sized staged combustion engine meant for the IPP space tug. Uses scaled down SSME components. Narrow throat and extension gives 1:400 expansion ratio and over 470s of Isp.

3/5 The RL20 evolved into the XLR-129. Initially intended for the ISINGLASS rocket spyplane and later P&W's contender for the shuttle program after uprating. Can operate with the nozzle retracted or extended. Here with 1:35/75 and 1:80/144 nozzles.

2/5 We also have the Pratt and Whitney RL20-P3 in sea level and vacuum versions. P&W's first attempt at a staged combustion design.

1/5 Coming soon to Bluedog Design Bureau, the absolutely gigantic Aerojet M-1. Part of a set of 4 "what if" cryogenic engines I'm working on that are almost done :) Considered for Nova before being cancelled as funding was diverted to Saturn V/Apollo.

Various mounting options including a fictional compact variant with smaller exhausts.

@torybruno I thought you might like this. An RS-68 engine I made for the Bluedog Design Bureau mod for KSP. Including my interpretation of what a regenerative model might have looked like if it had ever gotten made. #ksp #kerbal

2/3) The fairing is available in all 3 historical lengths and is extensible to non-historical lengths too. Pictured together with its 500 series older sibling in pic two.
