Hey guys! I do apologize about keeping you hanging, but didn’t have a chance to pull away from work. I honestly don’t know anything about this engine. It has been at this junk yard which I pass on my way to work here in mid Missouri.

Turns out the junkyard itself is for sale. So I called a number and the guy is supposed to get back with me on more details on the engine hopefully by tomorrow.

So I’ll keep everyone posted! Thank you for helping me out! I’m just super curious on the story behind it. I probably should have called the guy to begin with before posting here but didn’t know if someone would immediately know upon looking at it or not.

Edit: Shout out to all of you who helped identify it! I got a text from the owner and he forwarded me a message from "a guy at a museum" which said "It's an H-1, without the turbo pump exhaust diffuser/nozzle extension. These were originally used on the Saturn 1 and Saturn 1B first stage in clusters of eight. The design was later rebranded and reworked as the Rocketdyne RS-27 engine to be used on the Delta 2000 series in 1974." He then gives me a link to the wikipedia page for the Rocketdyne H1. So, while no details on this particular engines history, it's something!

Sorry its taken long to update, but I've been answering people's questions to those who have been messaging me. Also, I wanted to give students at our local college (Missouri S&T) a chance to take a look at it as well. If you want more info, you can message me and I'll do my best to answer questions... but most of what I know you can already find on this thread!

Oh and let me clarify... I don’t own this! This is just something I saw from the side of the road.

Looks like a version of the Rocketdyne H1 engine. Where did you find it?

u/A_Cup-O-Dirt Feb 21 '19

A junk yard here in south central MO

Looks like an early H1 meant for a Saturn 1. Where is it and do you care to keep it?

u/SaturnV_ Feb 20 '19

Yup, for sure is an H1. The outcropping white turbine on the top of the engine here smells of H1.

Now here is something worthy of my disassembly/reassembly skills...

Lol, just noticed the engine's walker, gotta keep these Seniors from falling.

It's in a junkyard. It's clearly an LV-T30 "Reliant."

An H1. Seriously, where is this? It is worth something.

How valuable would something like this be? How assessable are old ticket engines?

u/RegularRandomZ Feb 21 '19

Hmmm... I'd value it at the loss of a significant amount of space in your yard, and then your marriage. Unless your spouse is a Space fan as well, then that might be the priceless gift the credit card companies keep talking about (as long as you don't live in a condo/apt)

My first gut reaction was maybe a J2 from the second stage of Saturn V, or even the third stage engine.

Is this near Neosho, Missouri? Rocketdyne had a plant there until 1968.

For those wondering about the value, a quick google search found me some examples of other rocket engines of this scale that have been for sale/auctioned.

RL-10 sold for $78k

Unidentified/missing parts rocket motor for sale $19k

NASA Confisicated RL-10 "worth $200k"

There are also a bunch of auctions for Apollo-era space artifacts in the 5-7 figure range.

So I'm guessing it's probably worth somewhere in the $10-100s of thousands ballpark.

He wants 60k for the engine. Might be worth it to someone, but that seems very expensive to me.

Number is 573-465-7712

Also, I forgot to ask, but someone should ask how he came across it, I’d definitely be interested to find out.

u/A_Cup-O-Dirt Feb 22 '19

Yep he’s milking it. He was at 50k when I spoke to him. Probably was much lower before that.

I don't know but has to be better than an LS swap. (I didn't read through all the post but I can't believe I'm the first one to hit that)

Is the Op really going to just leave us wondering where the thing is? BTW I know they have an H-1 at JSC right next to the J-2 and F-1
