So Rogers is ######## with Space flight and multi million dollar contracts, for 100 jobs. Which at the top end would pay salaries of what 1 to 2 mil a year. Man these guys need to get their heads out of their ass's. This is why USA politics is so stupid that this sort of crap can go on.

 

The only reason reason to use AR1 instead of BE-4 are:

 

1. Price - if it performs the same and is cheaper all around. Then its the way to go.

2. Diversity - If Falcon uses Merlin's/Raptors, New Glenn uses BE-4, then Vulcan Uses AR1 an issue with 1 engine will mean less downtime for launches.

 

Also Orbital can keep using Russian engines.

Hard to comprehend. Finally get THE holy grail of engines available to them, and this TOOL wants to make a scene because they aren't going to be built in his State.

 

ULA have already committed to the BE-4 -- does he not understand that? Or does he not care?

*The only reason to choose the AR-1 over the BE-4 is if ULA want to keep using the Atlas-V chassis -- **but they'll need to re-tool it to accept two AR-1's (because a single AR-1 isn't going to be as powerful as an RD-180, so they'll need two) as well as lengthen the S1 to accommodate longer fuel tanks (because two engines are going to need more fuel) ... BUT that new, retooled Atlas-V NG  (next generation) with all five solids strapped to it should be nearly as powerful as a Delta-IV Heavy by then. Without exact numbers it'd be hard to say for sure but the AR-1's are expected to crank out around 500,000 lbf of thrust each; so it'd be a really good idea for ULA to consider it since the Heavy is being retired.

 

Hmm ... :D They could use both and have a win-win. And get Rogers off their six.

Earlier today ULA sounded like they're killing Athena and going with Atlas V and Vulcan, but these bozos are still talking Delta IV Heavy. Can't build Delta IV Heavy and Vulcan as it's line will need to be converted for Vulcan.

Off current topic//

 

I have not been following BO's progress of late, so am having a problem putting things together here...

 

Jeff is always stating...."step by step", but I think I missed a few items...

 

Images of 3 engines....test articles?

 

Contracts for launches.....where are these being built...at the factory that is still being built at the Cape?

 

Seems a bit out of context with "step after step"....this is now not a small step...unless I have been napping, and missed everything....:s 

Yup, you missed a lot.

 

The first 3 BE-4 engines have or are soon come off the line and will enter tests in about a month. After that, expect another build or two for sea level qualification. Uncertain if there'll be a BE-4Vac but it's very possible for New Glenn which flies about 2021-22ish.  Selling launch slots.

 

Their 750,000 sq-ft KSC factory is well along just south of the Visitors Center, with a test center and new pad build-out at the old LC-36, and something at LC-11.

 

As of December

Yup, nice to see the range getting commercial users to keep the lights on. 

 

Not BO, but StratoLaunch should start testing their big plane this year, with ops out of KSC using the shuttle landing facility.

Jeff Bezos does a deep dive into bearings in Blue Origin’s BE-4 rocket engine update

What’s the difference between ball bearings and hydrostatic bearings? You should have more of an inkling after checking out Amazon billionaire Jeff Bezos’ latest update on the development of Blue Origin’s BE-4 rocket engine.

 

The engine is undergoing testing for use not only on the New Glenn rocket that Bezos’ space venture is planning, but also on United Launch Alliance’s next-generation Vulcan rocket.

 

The BE-4 is designed to provide 550,000 pounds of thrust, propelled by liquid oxygen and liquefied natural gas. Bezos says that kind of thrust should be enough to send a payload on the first leg of a trip to the moon when seven of them are firing together.

 

But that kind of performance can involve a lot of wear and tear, particularly if you’re using traditional ball and roller bearings. To maximize the engine’s reusability, Blue Origin’s team is taking a different approach. To keep the BE-4 running smoothly, Bezos says the turbine at the heart of the engine’s turbopump will use a thin film of the fluid propellants as its bearings.

 

Reusability is a key selling point for the BE-4, and ULA will be watching the engine’s performance closely as Blue Origin puts it through full-scale tests over the next several weeks.

 

If the BE-4 stumbles, ULA might have to turn to a Plan B, and Blue Origin’s plans for the New Glenn satellite launch business would suffer a heavy blow. But if everything works, that’ll be a big boost for Bezos’ space company, which is also working on a suborbital spaceship powered by the smaller, hydrogen-fueled BE-3 engine.

 

Quote

Here’s the full text of today’s email update from Bezos:

 

“Although the BE-4 turbopump is smaller than your refrigerator, it generates 70,000 horsepower from a turbine running at nearly 19,000 revolutions per minute that pumps cryogenic propellants to pressures just under 5,000 pounds per square inch. To react the forces generated by the rotating turbine and impellers inside the pump, production rocket turbopumps to date have used traditional ball and roller bearings. For BE-4, we’re doing something different – we’re using hydrostatic bearings.

 

“A hydrostatic bearing relies on a fluid film supplied by a high-pressure source to provide support for the shaft and cause it to float without contacting the static structure except at startup and shutdown. The BE-4 main turbopump uses hydrostatic journal bearings for radial support and hydrostatic axial bearings to carry axial thrust. The system is bootstrapped. The high pressure fluid films for the bearings are supplied by the propellants themselves – liquefied natural gas and liquid oxygen – tapped off from the pump discharge flows.

 

“Material selection is a critical consideration for this approach, as there is physical contact between the bearing surfaces during the start transient before the fluid film is fully established and during the shutdown transient as the fluid film dissipates. With lab-scale tests and full-scale bearing rig tests using actual pump hardware, we evaluated over 20 material combinations in over a hundred tests, leading to our baseline material and coating choices.

 

“Extensive rotordynamic and computational fluid dynamics analyses have shown the feasibility of this design, and recent powerpack tests confirmed that this approach works during the startup and shutdown transients – the most critical phases. The shaft orbit plot below shows that the turbopump lifts off smoothly and centers during a typical start transient, demonstrating a smooth ride on a film of propellant.

 

“Why do we go to all this trouble instead of just using traditional bearings? Engine life. We’re relentlessly focused on reusability, and properly designed hydrostatic bearings offer the potential for longer engine life without refurbishment. This is one of the many engineering decisions we’ve made that we hope will lead to reusability – not just in principle – but to practical, operational reusability. If ‘reusability’ requires significant refurbishment, inspection, and re-validation between flights, then it simply won’t lead to the far lower launch costs we need to achieve our vision of millions of people living and working in space.

 

“We’ll keep you up to date as our testing progresses in the coming weeks.

“Gradatim Ferociter!”

Interesting approach ... but if any reverse pressure gets into the system at that point it's gonna be really bad. They're a smart bunch so I'm sure they've covered that contingency.

Jeff Bezos shares ‘sneak peek’ of Blue Origin crew capsule

 

Quote

Blue Origin founder Jeff Bezos on Wednesday released a set of images depicting the capsule his company is developing to launch passengers on its New Shepard suborbital spacecraft.

 

“Our New Shepard flight test program is focused on demonstrating the performance and robustness of the system,” Bezos wrote in an email sent to followers Wednesday morning. “In parallel, we’ve been designing the capsule interior with an eye toward precision engineering, safety, and comfort.”

From the latests news, the New Glenn is going to cost about 2.5 Billion to develop, which compared to Nasa is pretty cheap. It is going to live about halfway between Falcon 9 and Falcon Heavy in terms of up mass. Has there been any talk about how much a launch will cost?

 

https://www.inverse.com/article/30003-jeff-bezos-cost-blue-origin-s-new-glenn-rocket-2-5-billion

 

 

And if the prices are right, it'll have a real shot at being competitive. It's riiight at that sweet spot where Delta IV's bread and butter is (but with more all-round capability); it doesn't impede on Falcon Heavy's upper range and it can perform more tasks than Falcon-9 but doesn't meet the criteria for replacing the Falcon-9 outright at the lower end either. I'd say that Blue has a great workhorse on paper that actually fills a role, thus giving it a reason to actually be. They'll have a lot of business, more than they can book flights for -- if they can keep the costs down. That'll be everything. :yes: 

 

And unlike ULA, who couldn't keep expenditures in check, Blue Origin WILL actually try to do it. Bezos isn't going to let things get out of control, regardless of how we feel about the guy personally.

Blue Origin suffers BE-4 testing mishap

 

WASHINGTON — Blue Origin said May 14 it suffered a setback in the development of its BE-4 engine with the loss of a key hardware component of the engine in a recent test.

In a pair of tweets late May 14, the company said it lost “a set of powerpack test hardware” for the BE-4 on a test stand at the company’s West Texas test site in a May 13 incident. “Not unusual during development,” the company said, offering no other details about what caused the accident, or any damage to the test stand or other equipment.

The powerpack is a key component of a rocket engine that includes the turbomachinery that pumps propellant — in this case, liquid oxygen and methane — through the engine. The BE-4 powerpack generates about 75,000 horsepower, getting its power from a small engine called a preburner.

Blue Origin has been testing BE-4 powerpack systems since 2014, according to past company statements. The company has been gearing up for tests of the full BE-4 engine, once planned to begin in 2016 but which company officials had more recently been saying would begin in the coming weeks. The company announced in March that it had shipped the first BE-4 engine from its headquarters near Seattle to its Texas test site.

Funny that this came out basically the same day that the Tom Mueller interview became more widespread in which he admits to SpaceX blowing up quite a bit of hardware during Merlin 1D development.

    • So size is the ONLY selling point????? People have been plugging in PC's to TV's in living rooms for 20+ years. I would take a bigger box for more peformance. Also lot and lots of SFF/Mini ITX build guides out there.
    • My point is, if you buying this instead of a console for TV purposes, that you need to understand that you will not be able to play the most popular MP games with Steam OS. Now if you are not into those games, and into some of the perputual alpha/beta games on Steam then this is an option. I would argue a gaming PC would be the better route, more expensive but take the 1k -1.4k you are about to spend on this thing and build a better one. Because it is running Linux you can overide its 1080p settings. However The Verge complained about its 1080p cap and how you would have to get around it at the CLI, so someone buying this instead of a PS5 or Xbox might have a challege on their hands.
    • A review of Synology's BeeCamera software for the BeeStation Plus by Christopher White Synology is leaning into the BeeStation and the BeeStation Plus, and it's easy to understand why. While power users will want something more customizable, the BeeStation and its more powerful sibling, the BeeStation Plus, are great for those who want a device they can simply plug in, click a few buttons, and have it work as their own personal cloud. Until recently, the device was mostly used for the storage of files, photos, and videos, and with the Plus model, you could install and stream media through Plex. Synology recently released a new free application for the BeeStation Plus called BeeCamera, which is basically a stripped-down version of Surveillance Station. First, let's get the confusing naming out of the way. While you might initially think that BeeCamera is a physical device, perhaps a camera that Synology created specifically for the BeeStation Plus, that would be incorrect. BeeCamera is simply the name for the application that runs on the NAS and on your mobile device. I think the marketing team missed the mark here, but it does fit the other naming on the device, like BeePhotos and BeeFiles, I guess. Camera Support As of right now, only Synology-branded cameras are supported, which many will see as a callback to the drive locking the company implemented and then backtracked on. That said, while I 100% disagree on drive locking, I agree that camera locking for a device made to simply plug and play is the right decision. The whole point of the BeeStation line is simplicity. There are currently three camera model lines available, a wireless device for indoor use, and two PoE models for external use. CC400W (Wi-Fi): Plug it into power using the included power adapter, and connect it to your wireless network. This camera is rated only for indoor use and is the one I was provided to review the BeeCamera. $198.36, in line with the Unifi G6 Compact. BC510 (PoE): A bullet-style camera. Connect it to an Ethernet cable that is providing Power over Ethernet (PoE). This camera is rated for both indoor and outdoor use. $240. TC510 (PoE): A dome-style camera. Connect it to an Ethernet cable that is providing Power over Ethernet (PoE). This camera is rated for both indoor and outdoor use. $240. Although this isn't a review of the actual Synology camera, I did want to note that a positive for the Synology CC400W is that it uses a magnetic base. This means you can mount it on any magnetic surface, which is pretty handy. However, a downside to the camera is that it's powered by a built-in USB cable that's about six and a half feet (two meters) long. This means that the cable will probably be either too long or too short, but more importantly, if the cable is damaged at all, you'll likely need to buy an entirely new camera because there doesn't appear to be a way to replace it, unlike many competitors, like the Unifi G6 Instant. Hopefully, this is something Synology addresses in a future revision of the hardware. The BeeStation Plus supports up to four cameras. Setup The setup of BeeCamera is, like everything in the BeeStation family, very straightforward. Simply make sure you're on at least version 1.5 of the BeeStation OS, and BeeCamera is automatically installed on the device. BeeCamera Setup Screenshots Setting up the CC400W was just as easy. Plug it in, open up the BeeCamera app, and follow the on-screen steps to add the camera. During this process, you'll configure the camera name and how many days of retention you want to keep. The system will also automatically update the firmware for you. The whole thing took only a couple of minutes, excluding the time it took for the camera to update the firmware. Once the camera is connected to the BeeStation Plus, you can manage the various camera settings within the app, although there aren't many to choose from. You're able to configure whether the microphone will record audio (some privacy laws may preclude you from recording it), select what codec to use (H.264 or H.265), configure the color and exposure of the camera, and determine what data you want to overlay onto the video. Finally, you can set up AI detections so that BeeCamera will alert you if it sees certain things. These are all of the common detections you would expect in a camera system, such as people, pets, and vehicles. Under people and vehicles, you can also add extra monitoring for lingering and congestion detection, although pets are currently in "Lab" and therefore have no extra features yet. Recording in 4K using H.265 for 30 days will take roughly 300 GB of storage, which is very reasonable for most regular households, as the BeeStation Plus has 8TB of native storage. If you want to set up detection zones, you can. These are areas that BeeCamera will look at for the various detections, and are helpful if, for example, there's a tree in your frame and you don't want to be notified each time the wind makes the branches move around in the frame. Finally, you can also schedule when the camera should and should not be recording, which is a very useful feature. For example, you may want to record only at night when you're sleeping, but not during the day when you're up and about the house, so you can easily shut the camera off between 8 am and 10 pm. Each hour of each day can be configured to record continuously, only upon a detection event, or disabled completely. You can't fine-tune to record at a specific time, though, only hourly blocks on the hour. Daily Use The best part of BeeCamera is that it's easy and just works. If you only care about being notified when things happen, the mobile app sends those notifications and lets you click the button to bring up the video and see what's going on. For example, when I went out of town and had the camera pointed at the cat tower in our hallway, it was nice to be able to drop in and check that my furry friends were doing okay without me. Initiating the remote connection to the BeeStation Plus through the app is very responsive, but this will heavily depend on your ISP. In my case, using Xfinity, I'm able to go from starting the app to seeing live video in roughly three seconds, which is about the same amount of time it takes to connect to my Unifi UNVR system that costs much more. If you want to see footage from a specific day and time, you can do so using the calendar icon. You can also scroll through the timeline, looking for detections that are labeled in blue (vs. the normal gray when there's nothing of interest). There are buttons that let you go to the last/next detection on the timeline, which is helpful if you missed the notification on your mobile device. That's where the ease of use stops, though. While you can download clips that are flagged by detection, there's apparently no way to select generic time frames you're interested in, and the only place to download is to your phone. In addition, sharing a video shares the actual video, not just a link back to your BeeStation Plus. While that's good from a security and privacy perspective, it's a little awkward for sharing large videos. Limitations While the ease of implementation is great, there are some things that are lacking from BeeCamera. The most obvious is that there is no way to view the footage on the desktop. You can log in to the BeeStation Plus to see how much storage BeeCamera is using, but unlike BeePhotos and BeeFiles, there is no BeeCamera on the web console to manage or view footage. This means you'll be viewing all of your security footage on your mobile device, which is pretty limiting. In addition, there's no way to download the video to your PC without first using your phone as the intermediary. The one exception to this is that you can use BeeFiles to see the raw MP4 files. They're saved in 5-minute increments, and it's just raw data with no detection information or any other way to identify what any of them are. The lack of a way to interact with BeeCamera on the desktop also makes configuration of the cameras more difficult. For example, trying to set up detection zones using a tiny screen and your finger to draw boxes is more cumbersome than it needs to be. This reinforces the idea that BeeCamera is not made for power users. It's also missing some of the more advanced functionality of Surveillance Station. For example, I couldn't find a way to say, "Alert me if the thing in this zone is no longer there." Another major deficiency with BeeCamera, and a feature I suspect may come out in the future, is that while it can detect generic people, there is no specific facial recognition yet. This is an interesting omission, given the fact that other Synology tools can detect specific individuals, and competitors such as Unifi Protect also do it. This is probably a software limitation, so we will have to wait and see if this feature is added in the future. Conclusion If you need a security guard to monitor surveillance cameras to make sure your property is secure, then BeeCamera is not the solution for you. That said, you probably wouldn't be using a BeeStation Plus as the brains behind the system either. BeeCamera (and BeeStation in general) is clearly aimed at households that want to avoid sending personal data to Google and Amazon, and now want to add some cameras to keep an eye on their home and their pets while they're away. BeeCamera excels at doing this. The target market isn't interested in creating cases, tying multiple views together in a single pane of glass, or the like, and for the intended use case, the system works great. Where it starts to fall apart a bit is with more advanced features. Not being able to use a desktop app is a major compromise in my opinion, and having to do all of the configuration on a mobile device is annoying, but not impossible. If you don't want to have a full-fledged NAS device in your home, but still want control over your data (or maybe want an easy way to backup your data for World Backup Day), and want to add a couple of cameras to keep an eye on your house and your pets, this is a great, cheap, and easy way to go, and I suspect more functionality will come over time. If Synology releases a desktop app or at least a way to configure cameras and view footage on a desktop browser, this would be a near-perfect solution for a general home user.
