I am trying to determine typical relationships between engine mass and performance for various types of engines, so I'm looking for a broad spectrum of examples to extrapolate from. I'm segregating data by propellant and cycle, and for some categories such as staged combustion kerosene-LOX, I have plenty of data, but for others I have found very few examples.

Other than Kestrel, are there any examples of pressure-fed, kerosene/LOX engines with publicly available specifications?

Other than LR87, LR91, and the Viking family, are there any examples of gas-generator cycle, hypergolic-storable propellant engines with publicly available specifications?

The specifications I'm interested in are mainly vacuum thrust, vacuum specific impulse, mass, length and diameter. Sea level thrust/ISP and burn time are also nice to have.

  • $\begingroup$ Pressure feed kersoene/LOX was used during early ground tests of the F-1 engine for the first stage of Saturn V when the combustion chamber and nozzle should be tested before the turbine and pumps were available. The very heavy tanks for high pressure were no problem for a ground test. $\endgroup$ – Uwe Sep 25 '18 at 20:05
  • $\begingroup$ I'm really asking about production/flight engines, or at least configurations which were planned to fly. $\endgroup$ – Russell Borogove Sep 25 '18 at 20:06
  • $\begingroup$ @RussellBorogove thank you for posting and answering your own questions, I hope you realize how helpful all of your self-answered questions are :). It's like someone reputable telling you, "hey you should/could think about this" then delivering on the reason behind why it all mattered with an inherently credible source. $\endgroup$ – Magic Octopus Urn Sep 26 '18 at 1:10
  • $\begingroup$ Hah, I was just going through my old questions trying to see if any had answers I should accept, then thought I'd bounty this, then tried googling for the answer again and realized Astronautix was the resource I needed. I always feel cheesy when I self-answer. $\endgroup$ – Russell Borogove Sep 26 '18 at 1:11
  • $\begingroup$ astronautix.com isn't anything I've ever seen, it's really cool, I'm glad you posted it! Honestly, I'd love a weekly Borogove self-answer; it'd be informative, not cheesy, even on topics you consider blatantly obvious it would help someone. Anything unanswered belongs :). $\endgroup$ – Magic Octopus Urn Sep 26 '18 at 1:36

I did find on Astronautix several examples of pressure fed kerosene-LOX engines, some of them built, others "notional":

As well as some gas generator hypergolics, mostly Russian vernier thrusters:
