Spain needs to put new submarine design on a diet

Filed under: Europe, Military — Tags: , , , — Nicholas @ 16:33

If they launch the new class of submarines as designed, they might not be able to re-surface after diving:

Spanish engineers, who already spent some $680 million on designing the new generation S-80 class submarine, say it is a major “technical innovation.” There is just one problem the calculations show – if submerged into water, it may never come up again.

The Spanish media has been furiously discussing the errors made by the state-owned Navantia construction company, which has spent about a third of the huge $2.2 billion budget only to produce an ‘overweight’ submarine that is not able to float.

Spain’s Ministry of Defense has confirmed that Navantia detected “deviations” in the new submarine’s design, thus delaying its March 2015 scheduled launch for one or two years.

Navantia said an excess weight of up to 100 tons has been added to the sub during construction, and the company may have to redesign the whole craft.

The “Liberator” isn’t really a gun … it’s a political theatre prop

Filed under: Liberty, Media, Politics, USA — Tags: , , , — Nicholas @ 00:01

In The Register, Lewis Page points out that the 3D printed “Liberator” isn’t actually much of a gun at all:

People are missing one important point about the “Liberator” 3D-printed “plastic gun”: it isn’t any more a gun than any other very short piece of plastic pipe is a “gun”.

You can take my Liberator ... and shove it

You can take my Liberator … and shove it

Seriously. That’s all a Liberator is: a particularly crappy pipe, because it is made of lots of laminated layers in a 3D printer. Attached to the back of the pipe is a needlessly bulky and complicated mechanism allowing you to bang a lump of plastic with a nail in it against the end of the pipe.

An actual gun barrel is a strong, high quality pipe — almost always made of steel or something equally good — capable of containing high pressure gas. It has rifling down the inside, making it narrow enough that the hard, tough lands actually cut into the soft bullet jacket (too small for the bullet to actually move along, unless it is rammed with massive force). At the back end there is a smooth-walled section, slightly larger, into which a cartridge can be easily slipped.

It’s not much of a gun at all. But as with the old saying about the dancing bear, it’s not how well it dances but that it dances at all. After some 100,000 downloads, the company was requested to take the files offline on Thursday:

More questions about the Arctic Patrol Ship project

Filed under: Cancon, Military — Tags: , , , — Nicholas @ 13:48

Last week, the CBC’s Terry Milewski posted an article questioning the progress and ongoing costs of the Arctic Patrol Ship program. The ships are supposed to be based on the same design as the Norwegian Coast Guard’s Svalbard:

KV Svalbard

The design was purchased for $5 million with the intent of revising it for Canadian requirements. The government allocated an incredible $288 million for the revisions. The original Svalbard cost about $100 million in 2002 … but that was to design, build, and launch the actual ship. Not just to come up with a revised design.

In yesterday’s Chronicle Herald, Paul McLeod predicted that the price of the patrol ships will rise in the same way that the F-35 project costs have risen:

The mandate for the Arctic/offshore patrol ships is to do offshore work on Canada’s coasts and also be able to patrol icy northern waters. Yet a recent report by the Rideau Institute and the Canadian Centre for Policy Alternatives argues the ships will be able to do neither job well.

Co-authors Michael Byers and Stewart Webb say the ships will be too small to be effective icebreakers and will only be able to crash through thin ice in the warmer months. They also say the thick, reinforced hulls of the ships will make them too slow for patrolling jobs like chasing off smugglers or illegal fishing boats.

And of course, because we’re designing them from scratch, they will cost far more than an off-the-shelf design.

So the purchase of the original plans — a trivial amount in proportion to the current budget — was a waste of money because the new ships are in effect going to be a new design anyway.

The PBO only looked at two ships being built in Vancouver, but there’s no reason to expect the same problems won’t hit Halifax. The $3-billion price tag for the Arctic/offshore patrol ships has stayed the same for years, though purchasing power has decreased.

Ottawa still says it expects to buy six to eight Arctic/offshore patrol ships but almost no one believes eight is realistic anymore. The Byers-Webb report points out that the navy initially wanted the ships to be able to drive bow-first or stern-first, like Norwegian patrol vessels. That feature was ruled out; presumably it was too expensive.

The ships will still be built in Canada because it would be politically disastrous to move those jobs overseas now. Fair enough. There’s historically been a 20 to 30 per cent markup on building ships in Canada, says Ken Hansen, a maritime security analyst at Dalhousie.

So in summary, we’re going to be paying a higher per-ship price for fewer ships with lower capabilities than we originally specified? This really is starting to sound like a maritime version of the F-35 program. And the Joint Support Ship program. And the CH-148 Cyclone helicopter project.

Canada’s Arctic patrol ship design program just a job creation scheme that doesn’t actually create jobs in Canada

Filed under: Cancon, Economics, Military — Tags: , , , , , — Nicholas @ 16:58

The CBC’s Terry Milewski on the Harper government’s much-heralded shipbuilding program which is far more expensive than it needs to be — because of the demand that the work be done in Canada — and yet somehow doesn’t even manage to create Canadian jobs:

Public Works Minister Rona Ambrose and Defence Minister Peter MacKay announced March 7 in Halifax that Ottawa will pay Irving Shipbuilding $288 million just to design — not build — a fleet of new Arctic offshore patrol ships.

Irving will then build the ships under a separate contract.

However, a survey of similar patrol ships bought by other countries shows they paid a fraction of that $288 million to actually build the ships — and paid less than a tenth as much for the design.

In addition, the design of Canada’s new ships is based upon a Norwegian vessel whose design Ottawa has already bought for just $5 million.

The Norwegian ship, the Svalbard, was designed and built for less than $100 million in 2002.

Experts say the design price is normally 10-20 per cent of the total cost of the ships.

But don’t worry … jobs are being created or saved by this major Canadian government project … in Denmark and in the United States:

Another criticism of the project is that much of the design work — in a project meant to create Canadian jobs — is actually going overseas.

Although Irving will manage the design project in Nova Scotia, it has subcontracted the actual production of final blueprints to a Danish firm, OMT. Seventy Danish ship architects will work on those.

The job of designing the systems integration is going to Lockheed Martin and the propulsion system will be designed by General Electric, both U.S. companies.

This is only to be expected, say supporters of the project.

“We’ve been dormant here for better than two decades now. We don’t have the skill sets inside the industry,” said Ken Hansen, editor of the Canadian Naval Review in Dartmouth, N.S.

Sifting through the 3D printing hype

Filed under: Economics, Media, Technology — Tags: , , , — Nicholas @ 09:06

At The Register, Professor James Woudhuysen looks at the gap between the breathless hype about 3D printing and the current and near-term technological, political, and legal limitations:

3D printing, otherwise known as additive manufacturing, is a subject that pumps out enthusiasts faster than any real-life 3D printer can churn out products.

In conventional machining, computer-aided design and computer-aided manufacturing (CADCAM) combine to make products or parts of products by cutting away at, drilling and otherwise manhandling materials. With 3D printing, CADCAM works with product scanners, other bits of IT and special plastics and metals to build products up, whether through the squirts of an inkjet-like device or the sintering of metal powder by lasers or electron beams.

Rather in the same way, America’s somewhat self-conscious Maker Movement — several thousand DIY fans out to revive manufacturing through the web and from the privacy of their own garages — promotes 3D printing with layer upon layer of hype.

It’s true that 3D printing has its good points. Without having to engage in expensive retooling, a 3D printer can easily be reprogrammed to make variations on a basic product — good for dental crowns, for example. 3D printing can also make intricate products with designs that cannot be emulated by conventional, “subtractive” techniques.

[. . .]

Despite all this, those who blithely proclaim that 3D printing brings a revolution to manufacturing make a mistake. 3D printing does not represent a pervasive, durable and penetrating transformation of the dynamics and status of manufacturing. Nor, as The Economist newspaper has proposed, is its emergence akin to the birth of the printing press (1450), the steam engine (1750) or the transistor (1950). There is much to celebrate about 3D printing, and even its too-fervent advocates at least represent a reasonable desire to produce new kinds of things in new kinds of ways. Yet what characterises 3D printing is how, as with other powerful technologies today, it need only barely arrive on the world economic stage for zealots to overrate it, and for others to turn it into an object of fear.

“3D printing will be bigger than the web”

Filed under: Business, Technology — Tags: , , , , — Nicholas @ 12:46

While I’m not quite willing to go as far as Chris Anderson (quoted above), I do think 3D printing is going to be a fantastic development in our very-near future:

Chris Anderson has exited one of the top jobs in publishing — Editor-in-Chief of Wired magazine — to pursue the life of an entrepreneur, making a big bet that 3D printers represent a massive new phase of the industrial revolution.

He spoke at a Wired “Culturazzi” event, at the Marriott Union Square and to sign copies of his latest book: Makers: The New Industrial Revolution.

Mr Anderson is always an excellent speaker and his talk covered the beginnings of the Industrial Revolution, which he picked out as the invention of the Spinning Jenny in 1764 — a hand powered machine for spinning yarn.

I’d have pinned the start of the Industrial Revolution to the invention of the steam engine and its ability to power large numbers of machines thus enabling the first factories — which represented aggregated labor energy. Scale makes factories viable.

But I can see why Mr Anderson would favor the Spinning Jenny as it was a high-tech machine that was kept in a home — just as 3D printers are home based, completing a neat cycle of history.

Cutty Sark now housed in “worst new building in Britain”

Filed under: Britain, History — Tags: , , , , — Nicholas @ 10:33

Andrew Gilligan tells the sad story of the Cutty Sark‘s new “home”:

The architectural trade journal, Building Design, has announced that the historic tea clipper is the 2012 winner of the Carbuncle Cup, the wooden spoon for the dregs of British architecture.

The architects, Grimshaw, have taken something delicate and beautiful and surrounded it with a building that looks like a 1980s bus station. Clumsy and ineptly detailed, their new glass greenhouse around the Cutty Sark totally ruins her thrilling lines, obscures much of her exquisite gilding and cynically forces anyone who actually wants to see her to pay their £12 and go inside. The sight of people pressing their faces forlornly against the smoked glass to try to see something of the ship is one of the sadder in London.

Grimshaw have also punched a shopping centre-style glass lift up through the middle of the ship — and put two more lifts in a new square building, the size of a small block of flats, next to and towering over the ship herself. They’ve plonked a glass pod on the open main deck for a staircase (the old housing was wood, but that’s so nineteenth-century). They’ve installed lights on the masts which make it look like a Christmas tree. Above all, of course, they’ve hoicked the ship up on girders, dangling above the dry dock to create an “unparalleled corporate entertaining space” underneath — an act of vandalism that prompted the resignation of the chief engineer, who said it would place the vessel under unacceptable strain and end in its destruction.

Cutty Sark was severely damaged in a drydock fire in May 2007.

QotD: Detroit’s golden age

Filed under: History, Quotations, USA — Tags: , , , — Nicholas @ 00:12

It bears repeating that the ’60s — not the ’50s, and certainly not the ’70s — were Detroit’s golden age. The age of tailfins and bulbous deco car bodies was over, and designers went about the business of making the cars look as fast as their increasingly powerful engines actually made them go. The zenith of this is probably the Mustang, but its design aesthetic — less chrome, long lines, agonizing thought put into key details like the grille and the silhouette — dominated the industry, resulting in a decade of cars that look like they want to be driven, not parked (the ’50s) or rolled off cliffs (the ’70s.)

Innovative ways to use huge surplus of beetle-blighted lumber

Filed under: Cancon, Environment, Technology — Tags: , , , — Nicholas @ 09:07

British Columbia has a problem with their trees: too many of them are dead due to a massive increase in the population of the mountain pine beetle. The province is searching for ways to cope with the lumber from all the beetle-killed trees:

When life hands you lemons, goes the old saw, make lemonade. But what if life should hand you 18m hectares (44m acres) of dead trees? That is the problem faced by the province of British Columbia in Canada, which could lose over half its pine trees to the depredations of the fearsome mountain pine beetle. The beetle, no bigger than a grain of rice, is native to the forests of Western North America, where it kills trees by releasing a blue stain fungus that prevents the flow of water and nutrients. While the insect was historically kept in check by spells of cold weather, years of mild winters have unleashed an outbreak whose spread and severity is unlike anything seen previously.

As a result, the province is peppered with billions of dead, grey trees. If they are simply left standing, they will eventually either decay or burn in forest fires. In either case, they will release the carbon dioxide they stored while growing, swelling Canada’s total carbon footprint from 2000 to 2020 by 2%.

[. . .]

Canadian researchers have discovered other uses for BKP. Sorin Pasca, a graduate student at the University of Northern British Columbia, found that rain and snow conveniently wash out sugars and other organic compounds from dead pine trees. By grinding up the dry BKP and adding it to normal cement, he created a hybrid material that is waterproof, fire-resistant and pourable like concrete but that can be worked, cut and nailed or drilled like wood. The material, dubbed Beetlecrete, has already been used to make countertops, benches and planters.

Even more esoteric uses for BKP are on the table. Nanocrystalline cellulose, made up of microscopic needle-like fibres, is a lightweight, ultra-rigid material that can be extracted from wood pulp. Currently used to improve the durability of paints and varnishes, nanocrystalline cellulose promises strong, iridescent films that may find uses in industries ranging from optical computing to cosmetics. And, as a last resort, dead and fallen pine trees can feed British Columbia’s 800MW of bio-mass power plants, which burn pellets of BKP and other waste wood to generate electricity.

Royal Navy announces design of new “Type 26 Global Combat Ship”

Filed under: Britain, Military, Technology — Tags: , , — Nicholas @ 08:46

Britain’s Royal Navy revealed the design of the Type 26 today:

The announcement on the Type 26 Global Combat Ship has been described by officials as a “significant milestone” in a programme which will support “thousands of UK shipbuilding jobs”.

Basic specification images show sleek stealth features, familiar to modern warships, making them harder to detect.

The ship will be 148 metres long with a displacement of 5,400 tonnes.

The MoD has been working with BAE Systems since 2010 to determine the basic design for the ship. Detailed specifications of the vessel will now be examined.

Vertical missile silos for a range of weapons, such as cruise missiles, will be housed on board along with a medium calibre gun.

The hangar on board will house a Merlin or Wildcat helicopter and there will be extra space for unmanned drones, underwater vehicles or other specialist equipment.

[. . .]

The current plan is to build 13 of the ships, which are due to start coming into service after 2020.

The Type 26 will replace the 13 Type 23 frigates but the MoD is not giving a precise commitment on numbers until they know the unit cost.

The First Sea Lord, Admiral Sir Mark Stanhope, says the ship will be used “across the full spectrum of warfare”.

He added: “The T26 GCS will be a multi-mission warship designed for joint and multinational operations… including complex combat operations, maritime security operations such as counter piracy, as well as humanitarian and disaster relief work around the world.”

The US Navy’s still-experimental Littoral Combat Ship

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 08:29

New ship designs are highly complex and often take years to debug. The US Navy’s Littoral Combat Ship (LCS) program surprised most observers by settling on two different designs and splitting the intended order quantity between the two design firms. One of each design is in service now, the more traditional USS Freedom (LCS-1), and the trimaran-hull USS Independence (LCS-2). Each has had its own set of teething problems:

The LCS has long been a good source of bad news and potentially explosive revelations. In the last year the LCS design has been found to have structural and other flaws. The first LCS, the monohull USS Freedom, has suffered four major problems since it entered service four years ago. The latest one is a leak in a propeller shaft seal, which caused some minor flooding. Despite this Freedom was able to get back to port under its own power. Last year cracks in the hull as long as 17 cm (6.5 inches) were discovered, and the water-jet propulsion system broke down as well. Two years ago one of the gas turbine engines broke down.

The most serious problem is in the USS Independence, a radical trimaran design. It seems that a “dissimilar metals” situation arose when salt water, the aluminum hull, and some other metals got into close proximity with each other and extensive corrosion resulted. Aluminum hulls tend to corrode more than steel, but the problem became so bad with the USS Independence that, 18 months after entering service, it was sent into dry dock for corrosion repairs and design changes to eliminate the problem.

Cracks, corrosion, and equipment breakdowns are common in new warship designs especially designs that are radically different (like the broad trimaran shape of the USS Independence). Usually, these problems can be fixed but there’s always the risk that the new design will be seriously flawed, requiring extensive rework and a halt in building more ships of that class. So far, the U.S. Navy has not wavered in the face of potential design and construction flaws.

This is all part of the expected years of uncertainty and experimentation as this radical new combat ship design seeks to find out what works, to what degree, and what doesn’t. There is some nervousness about all this. The U.S. Navy has not introduced a radical new design for nearly a century. The last such new design was the aircraft carrier, which required two decades of experimentation and a major war to nail down what worked. Even the nuclear submarines of the late 1950s and early 60s were evolutionary compared to what the LCS is trying to do.

ESR on the limits of “lawfare” for Apple

Filed under: Business, Law, Technology — Tags: , , , , , — Nicholas @ 15:56

To put it mildly, ESR isn’t a fan of Apple’s lawfare approach to competition:

It’s beginning to look like Apple’s legal offensive against Android might backfire on it big-time. Comes the news that Judge Koh has declined to suppress evidence that Apple may have copied crucial elements of the iPad design from prototypes developed by Knight-Ridder and the University of Missouri in the mid-1990s.

Those of us aware enough of computing history to be aware of early work by XEROX PARC and others have always been aware that Apple’s claims of originality were highly dubious. Apple’s history is one of adroit marketing and a facility for stealing adapting ideas from others, wrapping them in admittedly excellent industrial design, and then pretending that all of it originated de novo from the Cupertino campus.

The pretense has always galled a little, especially when Apple’s marketing created a myth that, footling technical details aside, the whole package somehow sprang like Athena from Steve Jobs’s forehead. But it didn’t become intolerable until Apple began using lawfare to suppress its competition.

The trouble with this is that there’s actually a lot of prior art out there. I myself saw and handled a Sharp tablet anticipating important iPhone/iPad design tropes two years before the uPhone launch, back in 2005; the Danger hiptop (aka T-Mobile Sidekick) anticipated the iPhone’s leveraging of what we’d now call “cloud services” in 2002-2003; and of course there’s the the Sony design study from 2006, described by one of Apple’s own designers as an important influence.

If only Apple were honest about what it owed others…but that cannot be, because the company’s strategy has come to depend on using junk patents in attempts to lock competitors out of its markets.

An epitaph for the original Arts and Crafts movement

Filed under: Economics, History — Tags: , , — Nicholas @ 12:42

Colby Cosh has an interesting slant on William Morris and the original Arts and Crafts movement (for the record, I’m quite a fan of a lot of A&C artifacts, if not quite so much of their philosophy):

In the 19th century, William Morris preached a social revolution in which exploitative “useless toil” would be replaced by “useful work”. He dreamt of a world that would reject shoddy mass-produced goods in favour of objects made with care and craftsmanship. Any business that sells “artisanal” goods, whether the goods be curtains or crumpets, is essentially quoting Morris and referring to his promise.

That promise, of course, failed spectacularly. It did not even survive Morris’s own time. His “libertarian socialism” of crafted objects and honest work found itself drowned out at every turn by leftist alternatives which, more sensibly, accepted the power and inevitability of mass production. 20th-century Marxism wasn’t opposed to factories; it worshipped them, fetishized them. The fatal problem with Morris’s appeal is that he was just plain wrong about mass-produced objects necessarily being unlovely junk. We have been to Ikea; we know better.

Morris felt very strongly about this, and from his own historical standpoint, he was certainly on to something. It’s impossible for us to imagine what kind of things factories suppurated into the marketplace before things like statistical control charts were invented, or before items like micrometers were themselves mass-produced to a consistent high standard. Morris lived in a world where individual masons and cabinetmakers and weavers really were losing their livelihoods to a tide of undifferentiated, undistinguished banality; his feelings of alarm now seem fussy when we read him, but that is because only the better-made Victorian objects have physically survived destruction or disposal and reached our time.

Soon enough, however, the art of industrial design would come to the rescue. If Morris could have lived long enough to see the Studebaker Commander or the IBM Selectric II or, yes, the furshlugginer iPhone, he would have packed in the Arts and Crafts talk and gone straight to work designing pickle-jar labels. (Morris was not too consistent when it came to the ultimate logical consequences of a world made by hand, anyway. The influential Kelmscott Press he founded in 1891 favoured early printing techniques and letterforms, but it was, at any rate, a press; unlike his spiritual ancestor William Blake, he didn’t set out to mimic the appearance of illuminated manuscripts by the actual method implied in the etymology of the term “manuscript”.)

While I picked this section of the article to quote, you really should read the whole thing. It’s some of the most thought-provoking writing I’ve seen in months.

Danish Dutch design helps rescue the US Coast Guard from further embarrassment

Filed under: Military, USA — Tags: , , , — Nicholas @ 12:01

Strategy Page on the US Coast Guard’s latest cutters:

The U.S. Coast Guard recently commissioned the first of 58 “Fast Response Cutters.” These are 46.8 meter (154 feet) long, 353 ton vessels equipped with a 8 meter (25 foot) rigid hull boat launched and recovered internally from a ramp in the stern (rear) of the ship. Armament of the cutter (as seagoing coast guard ships are called) consists of a remotely controlled 25mm autocannon and four 12.7mm (.50 caliber) machine-guns, plus small arms. Top speed is 52 kilometers an hour and the crew of 22 has sleeping and eating facilities on board so the ship can be at sea five days at a time (and 2,500 hours, or over 100 days, a year at sea). The Fast Response Cutter is basically a slightly larger version of the Danish Dutch Damen Stan 4207 patrol vessel.

The Danish Dutch design was selected four years ago because, a year before the Coast Guard was finally forced to admit defeat in its effort to build an earlier design for 58 new patrol ships (Fast Response Cutters.) The ship builders (Lockheed Martin and Northrop Grumman) screwed up, big time. While the Coast Guard shares some of the blame, for coming up with new concepts that didn’t work out, the shipbuilders are the primary culprits because they are, well, the shipbuilding professionals, and signed off on the Coast Guard concepts. Under intense pressure from media, politicians and the shame of it all the Coast Guard promptly went looking for an existing (off-the-shelf) design, and in a hurry. That’s become urgent because of an earlier screw up.

Six years ago, the Coast Guard discovered that a ship upgrade program made the modified ships structurally unsound and subject to breaking up in heavy seas

Update: Thanks to eagle-eyed commenter Guan Yang who pointed out that the design is actually Dutch, not Danish. I’ve modified the quoted text to match the correct information.

Replacing “Lorem Ipsum”

Filed under: Randomness — Tags: , — Nicholas @ 12:09

You’ve probably encountered bits of Latin placeholder text on web pages, generally known as “Lorem Ipsum”, from the first words of the original. If you’re looking for something a bit edgier, you might try Samuel L. Ipsum instead:

Of course, I wouldn’t recommend actually using this unless you’re doing work for customers who wouldn’t be offended when it — inevitably — slips past the design phase and shows up in the finished product.
