How Boeing lost its mojo

Rafe Champion linked to this interesting thumbnail-sketch history of the decline and fall of Boeing:

Let’s start by admiring the company that was Boeing, so we can know what has been lost. As one journalist put it in 2000, “Boeing has always been less a business than an association of engineers devoted to building amazing flying machines.”

For the bulk of the 20th century, Boeing made miracles. Its engineers designed the B-52 in a weekend, bet the company on the 707, and built the 747 despite deep observer skepticism. The 737 started coming off the assembly line in 1967, and it was such a good design it was still the company’s top moneymaker thirty years later.

How did Boeing make miracles in civilian aircraft? In short, the the civilian engineers were in charge. And it fell apart because the company, due to a merger, killed its engineering-first culture.

What Happened?

In 1993, Clinton’s Deputy Secretary of Defense, Bill Perry, called defense contractor CEOs to a dinner, nicknamed “the last supper.” He told them to merge with each other so as, in the classic excuse used by monopolists, to find efficiencies in their businesses. The rationale was that post-Cold War era military spending reductions demanded a leaner defense base. In reality, Perry had been a long-time mergers and acquisitions investment banker working with industry ally Norm Augustine, the eventual CEO of Lockheed Martin.

Perry was so aggressive about encouraging mergers that he put together an accounting scheme to have the Pentagon itself pay merger costs, which resulted in a bevy of consolidation among contractors and subcontractors. In 1997, Boeing, with both a commercial and military division, ended up buying McDonnell Douglas, a major aerospace company and competitor. With this purchase, the airline market radically consolidated.

Unlike Boeing, McDonnell Douglas was run by financiers rather than engineers. And though Boeing was the buyer, McDonnell Douglas executives somehow took power in what analysts started calling a “reverse takeover.” The joke in Seattle was, “McDonnell Douglas bought Boeing with Boeing’s money.”

[…]

The key corporate protection that had protected Boeing engineering culture was a wall inside the company between the civilian division and military divisions. This wall was designed to prevent the military procurement process from corrupting civilian aviation. As aerospace engineers Pierre Sprey and Chuck Spinney noted, military procurement and engineering created a corrupt design process, with unnecessary complexity, poor safety standards, “wishful thinking projections” on performance, and so forth. Military contractors subcontract based on political concerns, not engineering ones. If contractors need to influence a Senator from Montana, they will place production of a component in Montana, even if no one in the state can do the work.

Wikipedia says:

The Iron Bridge is a bridge that crosses the River Severn in Shropshire, England. Opened in 1781, it was the first major bridge in the world to be made of cast iron, and was greatly celebrated after construction owing to its use of the new material.

In 1934 it was designated a Scheduled Ancient Monument and closed to vehicular traffic. Tolls for pedestrians were collected until 1950, when ownership of the bridge was transferred to Shropshire County Council. It now belongs to Telford and Wrekin Borough Council. The bridge, the adjacent settlement of Ironbridge and the Ironbridge Gorge form the UNESCO Ironbridge Gorge World Heritage Site. The bridge is a Grade I listed building, and a waypoint on the South Telford Heritage Trail.

Anthony Blackwall, who was the Shropshire County Bridgemaster, recounts the 1979 celebrations in “Historic Bridges of Shropshire”, Shropshire Libraries, 1985:

The most recent restoration was completed late in 2018:

The bridge, the first of its kind, was closed for a year after surveyors found cracks and stresses in its historic cast ironwork.

English Heritage launched a £3.6 million programme of repairs in autumn of 2017.

Kate Mavor, the charity’s CEO, came to the gorge to get a first-hand look at the historic bridge restored, and spoke of her pride.

“This is the first English Heritage site I remember coming to when I was about 11, and now it looks much the same as it did then.

“This is the first time I’ve seen it refurbished and I think it sits very nicely in the gorge, and with the red paint it will especially look good in autumn colours.

“I’ve been following the repairs closely since they began, it is an extraordinary project.

“The gorge is a world heritage site, the bridge was the first of its kind and it’s been there since 1779.

“It has survived a number of pernicious influences including an earthquake.

“We’re very proud of what we’ve been able to do here because it’s been unlike any other project of ours.

“We’re very grateful to everyone that has supported the project.

“The amazing response we had to English Heritage’s first ever crowdfunding campaign was fantastic too.”

Kate said that the surveys carried out before the project started revealed that the bridge had originally been painted a deep red, unlike the recognisable black or grey layer of recent years.

The real explanation for our lack of moonbases/Concorde 2’s/great walls/pyramids

Filed under: Books, Economics, Europe, History, Space, Technology, USA — Tags: , , , , — Nicholas @ 03:00

Homoitalicus Blog responds to a new book [At Our Wit’s End by Edward Dutton and Michael Woodley of Menie] that concludes that we (western civilization) are headed toward a similar fate as the western Roman Empire:

The reason that these staggering feats of engineering haven’t been repeated is more to do with economics and politics than with any perceived lack of engineering Genius in the population. The authors fail to reflect that emerging from the massively centralised wartime economy of the West there was an enormous technological infrastructure of scientists and capable administrators just sat there with no more Nazis to fight, communist megalomaniacs to support, Atom bombs to build and test, or greatest seabourne invasions in history to plan and implement.

This was probably the greatest concentration of intellect ever harnessed to a single cause and hopefully we’ll never need to see its like again

With the war done and dusted some new purpose needed to be found for all this talent, the way of government being what it is, returning all these geniuses to normal boring peacetime activity was never an option.

Newly nationalised aircraft industries took the wartime inventions of jet engine and the rest and evolved them with massive amounts of financial input from the government into Concorde, truly a magnificent aircraft but one which could uncharitably be described as using taxpayers’ money to ferry plutocrats from one side of the Atlantic to the other. Whether it ever really paid for itself is a moot point and the unseemly haste with which it was dumped after the crash tends to imply that its 50-year-old airframes were becoming a burden, and the economic case for making a new generation of supersonic planes is weak – luckily the will in the west for another taxpayer-funded effort doesn’t seem to be there. That is progress.

Likewise the man on the moon, possible only because of the Cold War space race.

The authors might as well explain the fact that we haven’t build another pyramid of Giza or Great Wall of China.

Their assertion that a general decline in the amount of creativity (which is correlated strongly with g) is justified by the observable decline in the quality of the output of the BBC. However other possible reasons for this are the infestation of Cultural Marxism and its baleful handmaid, Political Correctness, which really mitigate against creative thought. It is impossible to imagine making The Life of Brian, or The Sweeney or countless other shows which we enjoyed in our youth nowadays largely for reasons of PC and the fact that the BBC’s mission is now brainwashing rather than entertainment. State broadcasters the world over will suffer from the same problem, as does (worryingly) the world of academe in which speakers of truth or opinion which lie outwith accepted and very tightly bounded acceptability, are routinely no-platformed or summarily sacked. The teaching of history and the humanities generally has been debased, and only the STEM subjects seem to have resisted (excluding the question of Climate Change which has taken on the trappings of a religion rather than serious science).

As a consequence it is impossible to separate the effects of CM from the mooted results of a generalised decline in intelligence, and the authors are wrong not to point this out.

They don’t consider either the likely effect of the 20th century’s great blood letting in the fields of Flanders. A substantial proportion of the best and brightest of a generation were ground into the mud there before being able to procreate. I would be surprised if that had no effect on the quality of the gene pool.

The collapse of Genoa’s Ponte Morandi

Austin Williams reviews what information is currently available on the collapse of one of the towers of the Morandi Bridge (Ponte Morandi) on Tuesday:

The appalling tragedy of the Morandi Bridge, which collapsed on Tuesday, 14 August 2018, is a disaster that is still under investigation. At the moment, there are reports of 40 lives lost, but not much is known about the causes or the wider consequences. I am loath to speculate about either, but there needs to be a wider conversation and not simply kneejerk demands for corporate manslaughter charges against the private bridge-operating company, Autostrade per l’Italia. Heads will roll – deservedly so – but we must look at wider concerns about infrastructure, per se. (I caveat all of this by saying that pre-empting the ongoing investigation may reveal me to be wide of the mark.)

Firstly, the collapse was extraordinary. The bridge – built in the mid-1960s and named after the civil engineer Riccardo Morandi – is architecturally unique, and with this comes unique stresses that may have given rise to the catastrophic failure. A similar collapse of a similar nature and magnitude has not occurred before with a cable-stayed bridge. This bridge had 90m-high concrete towers that held tensioned cables fixed at an angle to the deck (the roadway), meaning that as the cables were being stretched by the loads, the towers were being squashed by the same loads. In engineering terms, the weight of the deck (and the traffic on it) was carried by the combined structure, meaning that the towers were under tremendous compression while the cables were under tension.

Bridge design always makes allowances – contingencies – for localised failure, and therefore even the most efficient, slender structures tend to be over-designed so that the engineers can sleep at night. The bridge has to imagine, for example, wind loads, snow loads, or 250 lorries being on the bridge rather than just 250 cars. But have the owners and managers of this bridge kept up with the reality, that in the 60 years or so since this bridge was constructed, loading conditions have significantly increased owing to increased freight volumes and vehicle sizes? Has this unseen attritional damage finally come home to roost?

In this bridge design, there is only one angled ‘stay’ (made up of four steel cables) encased in a concrete covering. The idea was that the concrete would protect the steel from weathering, corrosion and failure. Maintenance work as recently as 15 or so years ago replaced some of the cable stays and recoated them in concrete. Suggestions that cracks in the concrete exacerbated the ingress of water, which speeded the corrosion of the cables, are possible, but not totally convincing.

Were the cables to snap – possibly requiring more than one to snap due to the engineering contingency discussed above – then the deck would fall and possibly overbalance the entire structure. However, the fact that the towers collapsed in such a horrific fashion – seeming to crumble – may hint that the problem may lie in the foundations, where regular maintenance work was being carried out. We just don’t yet know. As Professor Gordon Masterton, from the University of Edinburgh’s school of engineering, told the Guardian, there needs to be a ‘forensic and thorough’ investigation to get to the root cause.

Malta’s Hand-Hewn Bomb Shelter Tunnels

During World War Two, the Grand Harbor in Malta was the most-bombed place in the world, under aerial bombardment for two full years because of its position as a central Mediterranean base for British air and sea forces. While these attacks were focused on the harbor facilities, most of the island’s population lived right in the same area, and civilian casualties during the war were substantial. In an effort to safeguard the population, a vast number of underground bomb shelter tunnels were dug.

The island of Malta is mostly relatively soft limestone, and the Maltese are quite experienced in working it, after millenia of quarrying limestone to build structures and digging it out to make cisterns and wells. This allowed an otherwise enormous project to be successful – using mostly hand tools, enough shelters were dug to safely house the entire at-risk population. Many of these shelters and shelter complexes are open to the public today, including the system under the Malta At War Museum, which we are visiting today…

I am grateful for the Malta Tourism Authority’s assistance in helping to make this visit and video possible!

Why Does The Porsche 911 Carrera Put The Engine In The Back?

When you’re sitting at the drawing board, one of the most critical decisions you’ll make in designing a vehicle is where you place the engine. The engine’s placement will have a huge impact on passenger space, practicality, acceleration, braking, weight distribution, and overall driving dynamics.

Porsche decided to put the 911’s engine in the back, behind the rear axle, way back in the day when the 911 was first designed. Since then, that engine has remained there, and while some might say it’s out of stubbornness, there are legitimately wonderful reasons for having a rear-engine car. In this video, we’ll discuss five different scenarios, and how a rear engine makes a lot of sense for each.

Horsepower vs Torque – A Simple Explanation

What’s The Difference Between Horsepower & Torque?
Why Is Peak Acceleration At Peak Power? https://youtu.be/cb6rIZfCuHI

Which is better, horsepower or torque? Two words that are often stated in the car community, but often misunderstood. This video seeks to clarify the difference between the two, without silly analogies like “horsepower is how fast you hit the wall, torque is how far you take it with you” (which, by the way, is highly inaccurate).

Torque is a force acting at a radius, while horsepower simply incorporates time into the equation. This video will discuss the differences, how each applies to internal combustion engines, how they relate, what peak torque and peak horsepower actually mean, and how to analyze torque and horsepower curves. Finally, what’s more important for acceleration, a car with lots of power, or lots of torque?

Let’s get technical. With the context of an engine: Power = Torque x Angular Velocity. In imperial units, this translates to Horsepower = Torque x RPM / 5252.

Primitive Technology: Mud Bricks

(Turn on captions [CC] in the lower right corner for more information while viewing.)
I made a brick mold that makes bricks 25 x 12.5 x 7.5 cm from wood. A log was split and mortise and tenon joints were carved using a stone chisel and sharp rocks. The mold was lashed together with cane to prevent it from coming apart when used.

Next, I made a mixture of mud and palm fiber to make the bricks. This was then placed into the mold to be shaped and taken to a drying area. 140 bricks were made.

When dry, the bricks were then assembled into a kiln. 32 roof tiles were then made of mud and fired in the kiln. It only took 3 hours to fire the tiles sufficiently. The mud bricks and tiles were a bit weaker than objects made from my regular clay source because of the silt, sand and gravel content of the soil. Because of this, I will look at refining mud into clay in future projects instead of just using mud.

Interestingly, the kiln got hot enough so that iron oxide containing stones began to melt out of the tiles. This is not metallic iron, but only slag (iron oxide and silica) and the temperature was probably not very high, but only enough to slowly melt or soften the stones when heated for 3 hours.

The kiln performed as well as the monolithic ones I’ve built in the past and has a good volume. It can also be taken down and transported to other areas. But the bricks are very brittle and next time I’d use better clay devoid of sand/silt, and use grog instead of temper made of plant fiber which burns out in firing. The mold works satisfactorily. I aim to make better quality bricks for use in furnaces and buildings in future.
