Soviet era rocket tech powers Anteres

From space flight now an article on Orbital Science’s Anteres launcher, specifically the rocket engines. It’s interesting that the Soviets were so good at some things and awful at others.

But then engineering is a very neutral endeavor and one that can adsorb your passion and develop your stoic nature…very good things in Stalinist Russia.

One should also remember that while ‘the west’ got the ‘brains’ of the Nazi German Rocket cadre (like Werner vonBraun) the Russian’s got the great majority, the working engineer types, who in the end have to slog through the agony of turning strokes of genius into real hardware, and it’s the slog that gets you deep capability not the strokes.

This is a Really Good question

From The American Interest || Walter Russell Mead’s Viameadia:

As is so often the case in American politics, those who produce MSM coverage and those who rely exclusively on it for news were the last to know what was happening. We’ve seen almost nothing but optimistic and encouraging coverage of gun control efforts, ending as usual in painful failure and disillusion. Many gun control advocates and their allies in the MSM are stupified and stunned by the votes.

“Is there really any point in throwing your political career away in order to give a few days’ passing satisfaction to New York Times editorial writers?”

ars technica article on the F1B engine the derivative of the Saturn 5 main engines competing for the strap on for the Senatorial Launch System… I don’t love the SLS but the F1B is exciting and worthy, I just wish it were part of a more commercially driven program.

2nd page has a great explanation of the difference between kerosene and liquid hydrogen as a fuel for first stage engines, fun for the rocket scientist in all of us…or at least me.

Another ars technica article on the computer guided rifle. Though really cool tech and something I’d like to try out at the range, it’s a pretty creepy concept when thought about in a little detail (and its obvious that Lee Hutchinson the writer had some qualms.) But every advance in hunting tech has been seen that way … ‘hey Oog that clubs really unfair you ought to use rocks like the rest of the guys!’ … even the barely socially conscious among we advanced (maybe) apes know that killing should not be too easy.

US Air Force = ‘hollow force’ ?

This article on the USAirForce in The American Interest is part of a series, incomplete as of this writing, on the US Armed Forces, and the road forward in this period of draw back and draw down. The ones on the Army and Marines are worthy and insightful but don’t get to the nitty gritty level required for me at least. While this AF article could be argued to be in the same vein I think it’s stronger and that may be because the technology and mission of the AF are very tightly interwoven making it simpler to see the overall threat.

The argument is that the AF has been all but static in the past 20+ years since Desert Storm. That a combination of victors-hubris along with techno-hubris and perhaps political ineptness have left us with a hollow force at the sharp end. The AF is arguably all over its technological mission in support of communication, reconnaissance, threat detection, navigation, etc, and has been shown to be king of battle in low intensity conflict (a turnaround of epic proportions from Vietnam.) But this camouflages the fact that if we had to do Desert Storm against a foe withe the modern equivalent of Saddam’s air defenses we would suffer vastly higher casualty rates, to the point of perhaps not being able to dominate the air space to anything like the same degree, perhaps pushing us back to an earlier era’s loss ratio’s.

There is a call to back the F35 and the NGB (next gen bomber) which I agree with since all other platforms are wearing and aging out (aging out happens as old tech ( particularly electronic and electromechanical) gets impossibly expensive to support because the devices and materials used are obsolete and no longer available sometimes even illegal due to toxicity or country of origin.)

I’m not bought in on the hollowness, yet. Yes the AF / DoD bolloxed the F35 and its now causing the above wear/age issue but does it matter? The first wave B2, B1 and cruise and strike missiles from B52’s etc would take down any known threat’s air defenses long enough for the channel to be cauterized by strike aircraft and special forces…which is what happened in DS. Yes some might have ability to hang tough with fighters, for a few hours, yes some might have backup lines and reserves, but having them and using them are two very different propositions once the AF is in their backfield.

What about a peer / near peer you ask? What peer / near peer I ask? Not NorK NorK, not Iran, not Russia or China either…a limited war against either is essentially the scenario above. Anything more in those two cases and sheer area would provide a huge force multiplier on their side. Thats ignoring the fact that both are serious nuclear powers and serious world diplomatic players who we are Never Going to War With directly until nuclear weapons are off the table…though of course you have to game the doomsday scenarios…but in those cases the war can never expected to be winnable or lovable in a conventional way.

Masten making progress

Xaero B vertical landing rocket demonstrator completed first hot fire tests at Mojave, Calif, on April 9.

From AWST space blog this picture and a short piece on Masten Space Systems Xaero B vertical landing rocket demonstrator

The Xaero is a re-configured, more powerful, higher-altitude version of Masten’s Xombie which has been demonstrating precision flight control and landing. This craft should be capable of 6km hops, an even larger upgrade could do 200 km! They will carry various NASA sponsored payloads.

Xombie has demonstrated cm accuracy at touchdown, there is discussion of doing away with the landing legs and coming down into a landing cradle! That would be a big weight savings. If proven here then it would be viable for all of the V-V (Vertical take off Vertical landing) programs such as Blue Origin, SpaceXs fly back Falcons…

What I find interesting is this progress juxtaposed with a piece regarding the AF reusable Booster program, canceled last year. Of course the demo program was ambitious, leap ahead and risky + expensive. Perhaps it shows that the more incremental commercial approach is superior; more robust, affordable and supportable especially with todays design, analysis and fabrication technology.

Cool solution to a real problem

Wired Autopia Piece

Safe comfortable service offshore service craft are a very real need with the growth of offshore infrastructure. Bigger conventional hull forms hare being built but in reality bigger is not a good option for service craft. This is a traditionally, and rightly, conservative industry but its also one where big break throughs can ignite rapid change.

The proposed craft is what is generically called a SWATH( small waterplain hull) design, and the proposer has it right about the advantages. Though a SWATH is usually intended for best transit performance ( ride, efficiency, safety and speed) the proposed ability to change the ‘ride height’ is different, in line with some mored rigs ability to ballast down for best ‘ride’ in a particular area or sea state.

Regarding transit, I think the writer may have misunderstood the concept creator, fast ferries are generally catamarans and these days often SWATH or SWATHlike craft. I think the lower hulls would be brought up to some intermediate depth for high speed transit not retracted into a hull riding form, which is both rough riding and less efficient. Either that or there is some patent/IP gamesmanship going on…which would not be surprising.
