Blue Origin expands its rocket engine factory in Alabama

Capitalism in space: Blue Origin yesterday revealed that it is hiring 300 more engineers and expanding the rocket engine factory in Alabama in order to produce flight worthy BE-3 and BE-4 engines.

Blue Origin in Huntsville spent the pandemic supporting the company’s main engine plant in Kent Washington with parts for the company’s BE-3 and larger BE-4 engines, [site lead Nathan] Harris said. “We are now actually in the process of building our first set of complete engines through our facility,” he said. Those first engines will be produced this year.

…“We’re getting very close,” Harris said. “They’re still doing quite a bit of retrofitting. As you learn, anytime you retrofit something that’s over 60 years old, it takes a little bit more and there’s a little bit more that you unearth that was undiscovered.”

Harris said he expects to be testing the BE-3 “in the next couple of months followed shortly by the BE-4.” [emphasis mine]

This may be good news for both ULA’s Vulcan rocket as well as Blue Origin’s own New Glenn rocket. Both need the BE-4 engine, and both have been delayed years because it has not been ready on time. While the engine problems appear to have been resolved, Blue Origin had not put any thought into developing a practical and affordable manufacturing process that would allow it to build enough engines to serve both itself and ULA.

This expansion at the engine factory suggests the company is finally moving into its production phase. The highlighted sentence above however also tells us that the first flight worthy BE-4 engines are still months away, which will further delay launch of Vulcan and New Glenn. It is now certain that neither will launch this year, putting both rockets more than three years behind schedule.

Blue Origin changes engines for New Glenn second stage

Capitalism in space: In order to maintain its goal of launch its orbital New Glenn rocket by 2020, Blue Origin has changed the engine it will use in the rocket’s second stage from a version of its main BE-4 engine to new version of their already developed BE-3 engine, used in their reusable New Shepard suborbital spacecraft.

A Blue Origin executive told SpaceNews the company is shelving development of a vacuum-optimized version of BE-4 and will instead use vacuum-optimized versions of flight-proven BE-3 engines for New Glenn’s second stage and optional third stage. “We’ve already flown BE-3s, and we were already in the development program for BE-3U as the third stage for New Glenn,” said Clay Mowry, Blue Origin’s vice president of sales, marketing and customer experience. “It made a lot of sense for us to switch to an architecture where we get there faster for first flight.”

The BE-3U is the upper stage variant of the liquid hydrogen-fueled BE-3 engine that has powered Blue Origin’s reusable New Shepard spacecraft on seven suborbital test flights since its 2015 debut. Mowry said switching to the BE-3U for New Glenn’s second stage will allow Blue Origin to conduct the rocket’s first launch in the fourth quarter of 2020. He declined to say how much time the engine change saves compared to the original configuration.

This quiet change, which the company made with no fanfare, carries with it some significant information as well as important ramifications. First, the BE-3 engine is less powerful than the planned BE-4, which is why they will use two BE-3 engines in the second stage instead of one BE-4, while also extending the length of the stage to accommodate more fuel. Though they claim the change will increase the rocket’s range, I suspect however that even with these changes New Glenn’s overall orbital payload capacity will be reduced.

Second, the change indicates that development of the BE-4 engine is proceeding slower than expected, threatening their 2020 launch goal. They have had one test failure that set them back, and the change suggests to me that they are having issues with making the engine restartable.

Third, if they have problems making the BE-4 engines restartable, this means their plans to reuse the first stage of New Glenn will be impacted. While those first stage engines do not need to restart on any single flight, reusing them requires this capability.

Fourth, problems with the BE-4 might cause ULA to reject it and choose Aerojet Rocketdyne’s AR-1 engine for its new Vulcan rocket. Up to now ULA has indicated it prefers the BE-4. These issues might change that.

Fifth, this change, combined with the continuing lack of New Shepard test flights, suggests that the company is increasingly considering abandoning this suborbital spacecraft.

I am doing a lot of speculating here, and could be very wrong on many if not all of these suppositions. We shall have to wait and see.

Blue Origin to begin flight tests of new rocket engine

The competition heats up: The rocket engine that Jeff Bezos’ Blue Origin company has been building is now ready for suborbital flight tests.

Blue Origin says the BE-3 is the first new hydrogen-fueled engine to be developed in the United States in more than a decade. It can be continuously throttled between 20,000 and 110,000 pounds of thrust. “Liquid hydrogen is challenging, deep throttling is challenging, and reusability is challenging,” Bezos said. “This engine has all three. The rewards are highest performance, vertical landing even with a single-engine vehicle, and low cost. And as a future upper-stage engine, hydrogen greatly increases payload capabilities.”

They hope to begin flight tests by the end of the year. Even as they develop this suborbital hydrogen engine, they are also developing an bigger engine for orbital flights in ULA’S next generation rocket that will replace the Atlas 5 and Delta.
