Rocket errors in stats?

I was going through the config files and noticed that the Rhino has a very odd Isp curve.

While clearly intended to be a heavy lifter, it has an Isp curve that's better suited to a pure vacuum engine. Isp falls from 305s in vacuum to 170 at sea level.

Was this a goof and it's supposed to actually be 270?

I also noticed that the LV-909 Terrier has spectacular sea level Isp, yet it falls off to zero precipitously afterwards.

This would make the LV-909 an excellent engine for a booster, and I'm pretty sure that's not what you had in mind.

*edit* The LV-909 is okay. Transcription error on my part.

Thanks,

Maybe these two got their curves mixed up?

Don't know about the KR-2L...

I saw an 85 on the SL LV-909 isp...

Are you joking?

I just went and double-checked the .cfg when you said that. Yeah, I made a transcription error.

The LV-909 is okay.

The Rhino numbers are definitely screwy, tho'.

I'll take a look soon.

Maybe it's an upper stage engine? It's vac ISP isn't great... Huh? This is confusing.

It's vacuum Isp, isn't great, but it's sea level Isp is atrocious.

That is normally a hallmark of an upper stage engine, not a booster.

Best,

Uh...I thought it was supposed to be the upper stage engine of the 3.75m parts. Why else make it look like a J-2X, compared to the 4 RS-25s of the 3.75m booster? To me, that Isp range makes perfect sense, when you consider the Mainsails and Mammoths to be lower stages (F-1, RS-25), the KR-2L, LV-T45, and Skipper to be upper stages / sustainers (LR-105, LR-91, J-2), and the LV-909/Poodle to be vacuum engines (RL10).
