The cool thing about full flow stage combustion engines is the propellant (because it’s cold - lol). The hot thing is the three combustion chambers that have to light and come up to power at the exact right time. Let the learning begin!

It's cold in Moses Lake, this is how we melt the snow.
~10 years ago I was a naive little new-grad engineer. I had just taken over the design of the BE-4 thrust chamber and nozzle from @AndyLapsa and I was in way over my head. Very proud and humbling to see these bad boys finally get off the ground!

Stage 1 tank coming together nicely. Sheet metal in - rocket out.
Y’all name your turkeys? 4 yr old named ours Mr. Poopy. Mr. Poopy is in the fridge getting ready for a nice warm spa day / deep frying.
This is an incredible picture
Sex is great... but have y'all tried dynamic space operations with a fully and rapidly reusable launch vehicle?!

Kick ass - hell yes!
Stage 2 looking mean! 🔥
Giddy Up!
Hopper is getting close to hopping, HUGE! Elsewhere at the same time we have first stage preburners preburning, first stage pumps balancing, first stage tanks welding, thrust chambers thrusting, and tons of beautiful learning along the way.

A lot happened in a week since I took this! Test stand got its hopper :)
If you are pissed off that your current software tools expect you to know the exact final design and manufacturing flow before you have ever even built the prototype, you NEED to check out Fusion by Stoke!

The PM org for @stokefusion is a team effort with me, BD, engineering, and design- and zero PMs. And we are crushing it!
The bloated PM org is at an end. Let's elevate the individual contributor who's obsessed with crafting great products.
A fun piece of info about tonight’s Chiefs-Dolphins game is that the Chiefs spent $2.2 million on a heating system under the field in 2016. So while the wind chill is -30 degrees, the actual field itself will be heated to 50 degrees. The pipes are 9 inches below the field.
1/4: I’ve been digesting my thoughts on the Vulcan/BE-4 launch, and I have many. Here are a few:
Quick look went well. Launched on the open of the window. Perfectly nominal mission. Dead on bullseye orbital insertion. For a minute there I thought I was in an Atlas mission…. #VulcanRocket
Wow, that was impressive. Congratulations @ulalaunch and @blueorigin. Seriously. Nailed Vulcan on the first time out. That shit is hard.
My babies finally flew! Holy moly 🚀😍
Two BE-4 methane engines from Blue Origin and two GEM 63XL solid rocket boosters from Northrop Grumman power the first United Launch Alliance Vulcan rocket toward space
Shipping an upper stage every 2.5 days is mind boggling. No one really seems to care because Falcon launches are routine now, but *getting* to the point of making Falcon launches routine was absolutely heroic.
@Yrouel86 @TurkeyBeaver @_lenny97 Main thing right now is to accelerate our supply chain and get our production rate up so we are consistently shipping a 2nd stage/Mvac every 2.5 days. The supply chain is a very challenging thing to accelerate and sustain as we are consuming tens of thousands of specialized parts…
This is wild 🤯. Ok twitterverse (Xverse?), who doesn’t love an underdog!?

✅ Proof test complete. ⏭️ Next stop: Returning to HQ to integrate the remaining fluid systems. The dev tank is full diameter and has all the complexity of the flight design but is shorter than the flight tank. #StokeSpace #RapidlyReuseableRockets #DynamicSpaceOperations
