It Seems That Blue Origin BE-4 Engine Manufacturing Is Completely Failure: After more than four years of frustrating delays, Blue Origin is finally making significant progress toward completing the development of its powerful BE-4 rocket engine. At present, engineers and technicians with the company are assembling the first two flight engines at Blue Origin’s main factory in Kent, Washington.
The company aspires to deliver these two flight engines to United Launch Alliance before the end of this year, although that increasingly appears to be a “stretch” goal. Delivery may slip into early 2022. And in order to make this deadline, Blue Origin plans to take the somewhat risky step of shipping the engines to its customer before completing full qualification testing. This delivery has been a long time coming.
United Launch Alliance, or ULA, first agreed to buy the engines from Blue Origin back in 2014. It was a bold bet by ULA, a blueblood in space launch, on a new entrant to the market. But with the BE-4 engine, Blue Origin founder Jeff Bezos was promising a relatively low-cost, high-performing engine with a power output comparable to a Space Shuttle main engine.
At the time of this initial agreement, Blue Origin said the BE-4 would be “ready for flight” by 2017. The BE-4’s delayed development has, increasingly, been the subject of keen interest. This is partly because ULA has been working on its new Vulcan rocket for a number of years, and that rocket is important to the future of the company.
The military is also eager for this delivery, as ULA is a primary provider of launch services to the Department of Defense alongside SpaceX. They hope Vulcan provides lower-cost launch services with engines manufactured in the United States.
Finally, many in the space community are genuinely curious about the cause of the delay. Despite this widespread interest, however, Blue Origin has said almost nothing publicly about engine development.
Therefore, this story attempts to provide some context for why the BE-4 engines are late. It is based on anonymous sources at the company’s headquarters as well as industry officials, some of whom would likely be fired if they were named.
According to many sources, the blue origin is unlikely to deliver two flight-ready versions of the Big Four rocket engine. Two United Launch Alliance before at least the second quarter of twenty twenty-two.
This increases the possibility that the debut flight of laws much anticipated new rocket Vulcan could slip into twenty twenty-three Vulcans. The first stage is powered. By two B E four engines which burn methane and are more powerful than the space shuttle’s main engines.
Sources say there recently was a relatively small production issue with the fabrication of the flight engines at blue origin’s factory in kent Washington As a result, the engines will not be completed and shipped to the company’s test stands in west texas until next year.
Once there, each engine must be unpacked, tested, and then reconfigured to move to the LA Rocket Assembly facility in northern Alabama a reasonable no earlier than the date for the engines.
Arrival at the rocket manufacturer is now April of two thousand twenty-two and this assumes a smooth final production and testing phase. But as we all know, manufacturing engines is very difficult and would require a lot of investment.
Even though SpaceX is now in a Raptor engine crisis, Jeff Bezos still has a lot of work to catch up on. This is truly a dire situation. and how did LA react to this continuous delay What was tony Bruno’s plan and how will it change you Ella declined to comment on specifics about the production issue.
People had often seen that Tony Bruno always covered for Jeff at many previous delays. However, the company now said it was disappointed that it did not receive these two flight engines in twenty twenty-one As anticipated, we are disappointed that we will not be receiving Vulcan flight engines from the blue origin by the end of the year, but they will be arriving early next year, the company said in a statement.
The certification program is moving along very well and the production engines are being manufactured. We look forward to Vulcans first launch in twenty twenty-two However, it now seems far from certain that Vulcan will make its debut in two thousand twenty-two and there is a lot riding on this rocket and its timely debut, which will replace both the Atlas and Delta rockets that ULA has flown.
The US military is counting on Vulcan to lift about sixty percent of the nation’s national security payloads into space. from twenty twenty-two to twenty twenty-seven at. At one point the Vulcan rocket was expected to debut in 2020 the US Space Force and EULA have already agreed to move the first military mission assigned to Vulcan designated U S F fifty-one onto an atlas five rocket.
However, LA has since said that all of its remaining Atlas Rockets, which are being phased out due to reliance on the Russian-built road one-eighty engine, are allocated to other missions. Therefore, it’s not clear.
That other military missions can be moved off of Vulcan and onto an Atlas, assuming the be four engines arrive at UCLA in April, the company would have about eight months to prepare the rocket for a test flight in two thousand twenty-two which will carry a small lunar Lander built by a private company Astrobotic.
This is the first time that EULA which was formed out of the launch divisions of Boeing and Lockheed Martin in two thousand five has taken delivery of a brand new first-stage rocket. Engine as part of booster development.
However, when Boeing and Lockheed first used the R S sixty-eight and R D one-eighty engines for their Delta and Atlas rockets, it took an average of nineteen and a half months from engine delivery to first flight. Vulcan is not expected to require this much time to incorporate the B E four rocket engine.
However, during our Reporters roundtable in December of 2020 U L A chief executive, Tory Bruno explained why. In a response, turns out a LA can’t wait for blue origin. Earlier that year, EULA had taken delivery of Pathfinder engines, which are nearly identical to the flight engines, but not designed to be ignited.
But what is the value of a Pathfinder and Canula improving the launch time Bruno said these Pathfinder engines have allowed EULA to do a lot of the work that is involved in preparing a rocket for launch in terms of assembling the propulsion.
End of the booster sending it to the launch site and ensuring that it links up with the ground systems therefore fueling and other operations. These are really big, heavy, complicated pieces of machinery Bruno said so they have custom tooling that handles them in the factory and aligns them, and helps us to install them in the rocket.
We don’t really like to adlib anything in our rocket factory, so every move that is made is in a process instruction that has been proved. Certified and then locked down and configured. What we’re doing in this initial pass-through that I call pathfinding.
It’s making sure that all of that is exactly perfect. Over the last year or so, you’ll have used the Pathfinder engines to test the vehicle assembly process, move it into the transport ship, travel to Cape Canaveral Space Force station in Florida, transferred it onto the mobile launch platform, and test ground systems.
As a result, Bruno said the nineteen-and-a-half-month yardstick from the earlier Atlas and Delta development programs is not comparable. All these pre-launch activities were part of that.
The big span that you looked back on and we are able to work off almost all of that with these Pathfinder engines right up to just literally short of the flight readiness firing and then at the last minute, we’re able to bring in the flight engines, take them through that whole evolution that has already been a trailblazer for them, and so that’s why you don’t need them as early.
But whether Blue Origin will continue to delay the launch date still makes their partner think twice.
