Ship to Shore Connector… Landing Craft Air Cushion, only the Gov’t could make something this cool boooring

 These are the final stage of the powerful conveyor that is the Navy’s Gator Fleet, the numerous, rather ugly, remarkably capable ships that carry the Marines to the far ends of the world and deliver them on the beach when needed.  While this fleet has been mainly a humanitarian instrument for many years now it is one of the principal reasons for the US Navy to be as big and capable as it is.  The US Navy has many tasks the most obvious ones are to keep the sea lanes open for merchant traffic.  While air freight is important these days it is the vast cargo ships carrying oil, ore, containers, and vehicles that really undergird the world merchant economy.  The US Navy also provides our most secure strategic weapon the strategic missile submarine.  The US Navy and the Marines hold at risk every trouble maker with a maritime coast, providing the implicit or explicit threat that major combat boots (and tracks) can be on their ground if they provide the right (or is that wrong) stimulus.

So now I become a product shill for Logitech

I used to use MS mice and keyboards but have found over the years that they can be a bit iffy regarding quality, they always look nice but after a few weeks they either quit working or seem to require unplugging/replugging (rebooting) every few days or hours and then quit working altogether.  I also found that the early big wireless USB keys were annoying to damaging.  Then I found Logitechs ittle bitty USB keys, at first one per device but now they have a unifying key that works with up to six devices per ea, now every computer I own has one of the keys and one, two or three devices connected.  They just work and the software for managing the devices and the key system is simple intuitive and again just works.

I just bought my second set of wireless mice + Keyboards this evening, an M525 mouse I got for 24.99 and a K360 (compact) keyboard (29.99) to connect to my old ThinkPad T42 that I have just dual monitor connected to my big DELL 24 in monitor sharing it with my DELL psuedoUltrabook from work.  My work setup has a M515 mouse on a unifying key and they don’t bother each other a bit.

By the by, Dells are inexpensive but solid, easily managed machines for the working drudges in the world (like I me when thinking for a buck) but I bought a Leonovo ThinkPad for myself and my writing habit.  While I did not go overboard on hard drive (and maybe should have) I did put in a big dollop of main memory and paid for the upgraded graphics.  Those splurges plus the inherent ruggedness of the ThinkPad have served me well.  I have typed many hundreds of thousands of words on the world class keyboard (the A key plastic is word down so its ridged and the graphic has worn off) but it still boots up faster than any of my Dells, XP is still rock stable and II still love the trackpoint mouse knub in the middle of the keyboard.  It’s lighter than most of my Dells up until the latest little devil and the 14 in conventional aspect screen is better for a writer than the movie slot screens that are so popular today.

So anyway, there you have it, Logitech rocks, Thinkpads rock, Dell has its place in the scheme of things.

Cheers out there

It’s probably right because it’s clean and simple looking.

From SAE drivetrain e-newsletter

Arens’ automotive-hardened traction inverters with power ranges from 30 to 500 kW (40 to 670 hp) are for applications ranging from large transit buses and medium-duty trucks to hybrid passenger cars. With the Powerpac series, adapting an existing vehicle design to hybrid power does not involve intensive re-engineering. The Arens Powerpac 100-kW (134-hp) traction inverter features a high power density in a compact enclosure designed to fit with the battery, in the vehicle’s existing battery box. The inverter offers an insulated gate bipolar transistor-based design and is suitable for truck, bus, agricultural, and construction equipment applications. All Arens inverters feature cast enclosures sealed to IP67 with intelligent thermal protection.

Very much like what my team at SatCom came up with for the AIPM Advanced (or Automotive depending on the audience) Integrated Power Module. The switches are bolted to the base the bus bar connects across them with capacitors integrated as close to the devices as possible and the gate drive and controller board on the other major flat face. Doubt any of the Aren’s team ever saw anything we did, it’s just the most economic and sensible use of surfaces and volumes to get the best performance.

Not a new technology but if these guys can bring it to market at a significantly lower total cost of ownership number they are going to ignite the market.

Biggest issue with SftSwt has always been complexity and consequent reliability issues.  If these guys have reduced the parts and interconnect count (in other words integrated the controls and sensors)they are on the right path.

Another Celebrity Seeker…and the Apple Culture

As far as I can see the whole mess with Mike Daisey is the common American confusion between celebrity and profundity.  The Wikipedia entry above starts out :

“Mike Daisey (born 1976) is an American monologist, author, and actor best known for his full-length extemporaneous monologues…”

And that sums it up, he’s not a reporter, does not purport to be one and yet his monologuing is taken as a serious expose of Apple’s factories in China.  The whole problem is that NPR got confused about what they had, it was in some ways not even Daisey’s fault…until he denied any fault as with so many things today, “..it wasn’t the break in it was the coverup…” inept spinning.

Now Apple knows that its old core and even its younger adherents are biased to the progressive/lefty “down with capitalism” side.  Apple is also forced to build their products in China these days, they could not keep their products in the painfully but not prohibitively expensive category otherwise.  They will not purposely turn a blind eye to abuses at their Chinese factories, especially as they know that they are likely to depend on Chinese customers for a lot of growth in the not too distant future.  

Victor Russell Mead at Via Media has the best overall take on the Daisey mess, I won’t go into it any more.

However thinking about Apple and China does bring up other issues about manufacturing and the outsourcing of said.  Two Questions of Apple: 

  1. The iPad, iPhone, iPod are all flat, sandwich build products, why not automate the production and do it in the US?
  2. Aren’t you  afraid of giving your products intellectual property to the Chinese, who have quite blatantly set about appropriating everything they can from anyone with good ideas?

And the answer is the same in both case.  Apple has an extremely short product cycle most of the time and tries to keep their products under wraps until the last second. They use a very deep supplier base on the Asian shore to the fullest extent, the parts are cheaper and more available there, and Apple parcels the parts out so its hard for their competitors to figure out what’s coming until the last month or so before introduction.  Final assembly of many gadgets is the most labor intensive part of the process and the hardest to automate, it can be done but if you are only going to build the product for a couple of years then completely rejigger why put the capital into a fixed site?  And its the Social IP of how you design and proof out a product like the iPad in a very short time that is the secret sauce as much as anything else.  And that IP the IP of the Apple way, the Apple Corporate Society, that gives them the edge, and its not one that anyone can copy easily.  The whole infrastructure of design spin, parting out, having multiple products at various levels of development at one time, and staying mum, that keeps Apple ahead, their competitor’s head’s spinning and the Apple paparazzi merrily dancing in trail.

DefenseTech calls it a Bomb Truck

20120311-204543.jpg
DefenseTech has some Chinese eye candy regarding the large and apparently powerful J-20 in development / trials. They call the aircraft a bomb truck and that seems likely, the analogy to th 70’s vintage FB-111 seems apt.

20120311-205744.jpg
These aircraft are the conceptual descendants of WWII aircraft like the Mosquito.

20120311-205757.jpg
The thing I find peculiar is how open the Chinese are about the testing of the J-20 it’s like a reality TV show. One part of me wants to say the Chinese know everyone will be spying anyway, to reduce the tension, just go ahead and let the pictures be taken, bask in the glow of self righteousness, and the fact you’re saving money. And at the end of the day why does one care, the real secret sauce is deeply buried in the materials and internal details and is not readily apparent on the surface anyway…The other part wonders what’s really going on in some distant corner of the country.

The Army really needs to ‘cool it’s jets'(calm down in the lingo of the ‘Gray Lensman’)

In the NDIA’s National Defense magazine’s blog there is a post: Don’t Rush to Buy New Vehicles, Army and Marine Corps Warned

The traditional approach to updating U.S. military hardware — spending years and billions of dollars on next-generation designs — is no longer working for the Army and the Marine Corps as they seek replacements for their combat vehicles.

——

One reason for the military to hold off on buying new vehicles is that there are no technological silver bullets to make military trucks, tanks and personnel carriers less vulnerable to enemy weapons, …. Adversaries can acquire and deploy antitank weapons and roadside bombs much faster and at far less cost than the U.S. military can build countermeasures and survivable vehicles,

——

It’s not clear that the Army or the Marine Corps can “get out of this box,” Outspending the enemy in this case is a losing battle. … “Adversaries’ use of guided weapons, relatively cheap and rapidly fielded anti-armor weapons … threatens to increase significantly the costs incurred by U.S. ground troops in accomplishing their assigned missions,”

——

The Army’s procurement bureaucracy is still reeling from the failure of its $200 Future Combat Systems. Although the follow-on program, the Ground Combat Vehicle, is far more modest, it is not clear that it (will) offer a substantial technological boost compared to existing vehicles

——-

Army buyers might still be somewhat (IMO are totally) deluded by the thinking that doomed the Future Combat Systems. At the time, FCS officials touted the program for its advanced information network, which would give commanders an instant view of the battlefield and allow them to see the enemy without being detected.

After the termination of FCS, the Army continued the push for an advanced communications network, which is now billed as the services number-one modernization priority. The problem, … is that the Army still assumes it can deploy a network at will. “The assumption is that we are operating in a permissive environment … that once we set up the network, nobody is going to tear it down,”

——
We have operated in a permissive environment, electronically and even threat wise for the past decade at least. We have also operated in a nation building civil war environment in urban, suburban environment. Even in the ‘Stan the military faces an enemy with limited access to weapons beyond RPGs and IEDs but these have proven the Bradley is no longer viable and driven us to develop armored modestly off road vehicles like the Stryker DVH, MATV, and MAXPRO MRAP.

These vehicles use existing technology and are enough over designed to allow for evolution. They are too heavy for the Army and USMC but the effort put into the ‘light weight’ replacement the JLTV Family has already cost huge amounts and the only way the Army/USMC kept the program was mandating a weight(26,000lb), cost ($250,000 ea) and protection (MAXPRO equivalent) and letting everything else float or be a special kit. The program has been a feeding trough for the Mil-Ind-Bandit-complex for several years not for truck builders supported by the Army funding some high end components. In fact the truck builders and high end suppliers have been funding their own pragmatic tech programs based on industrial/commercial insights that in the end the Army and USMC have bought.

Recently a couple of high ups in the acquisition corps said they’ve been meeting the soldiers needs and all the grief about Comanche, Crusader, JLTV EDM, EFV, FCS, etc is all noise. Bull-crap!

Once it might have had some truth, the Army/USMC did projects to build tech and keep design experience honed. Much of the money went to top grade suppliers of engines, suspensions, transmissions, the primes never intended the vehicles to go to production, everyone learnt and had tech on the shelf. Those days are gone.

These days the programs are too tightly focused and the programs are ‘mapped’ to lead to production. So the top tier suppliers go for them, often get more than one ‘team’ funded and develop futuristic Advanced Development Models, designed to highly refined specs that require essentially custom components. To keep their engineering teams fed they keep most of the work in house and over-ride input from the lower tier suppliers they do use. The specifications are too specific and often contradictory, open to interpretation, and all too often evolving. Money swirls down the toilet by the bushel. New management comes in, new ‘baselines’ established more money flushed and eventually the program collapses. Little of the technology is of use elsewhere.

The world class suppliers all largely ignore Army programs because they have spent too much money on programs that are ill conceived and almost bound to fail. Where the automotive industry does work on gov’t programs they try to focus on programs with clear near term needs, like the highly successful, Stryker, MATV, and later MRAPS.

At the end of the day we’ll be better off letting things settle out while we fund evolutionary and component technologies. The thousands of bright young officers coming back from Iraq and the ‘Stan need to settle in, study the world, history and the potential for tightly-constrained battlespaces, they’ll be the ones to figure out what comes next, not the old guard who claim they’re ‘just fine…’
