As I have written before Europe will have to define it’s geographic borders once and for all. The British Iles and Scandinavia are not and cannot be part of a united Europe they are by analogy Japan the first and Korea on steroids the second. As for jet engines isn’t there some better technology around to replace them.
At least alloy strength is hard to fake under testing, unlike the reliability of the software component.
Can’t find the page to post this for USS McCain as a total of 3 pages displayed with a search, so I’ll drop it here.
Navy filing homicide charges against 2 ship commanders over fatal collisions that killed 17, including 3 Marylanders.
The destroyer USS John S. McCain collided with an oil tanker in coastal waters off Singapore in August, killing 10 U.S. sailors.

Time to get out from under the yoke of the USA[CIA/NASA/Military Industrial Complex/FAAMGA].
Perhaps, finally getting rid of that decades old nemesis GLADIO, …
er, I mean NATO.
Germany/France want to become powers unto themselves; independent and making their own sovereign state decisions, not bound to the USA’s/Israel foreign policies, etc. – against their own sovereign interests[of which the USA is a poster child for, at least in terms of 99% of her citizens]
They also need to get their own independent currency system – as Russia, & China are ambitiously inching towards.
The so-called country[USA] run by an international conglomerate of financiers, with an economy based on junk economics, is not one to become part and parcel to.
This is just one other straightjacket strap to cut loose from.

I almost became a Powerplant Engineer rather than an Aerospace Engineer. Jet engines really fascinated me. So, I have followed jet engine developments over the years.
The ‘hot section’ is the most difficult part of a jet engine. Within that section, the blades of the high-pressure turbine are the most difficult. They are the ‘crown jewels’ of an engine company, and the technology is extremely guarded.
How hot you can burn your fuel determines the ‘efficiency’ of the engine. But to extract power for fan-blade (essentially, propeller) use from the burned fuel, you have to pass-it-by the blades of the high-pressure turbine without melting them. Getting pounds of thrust (performance) is easy; just burn more fuel. Afterburners are the extreme of this. Dump-in fuel, get thrust out. Just not fuel-efficiently. So, it is easy to produce a ‘dragster’ but hard to produce an efficient ‘dragster’.
Getting the same performance with miserly fuel-flow is hard. You run the engine as hot as you can without melting the blades of the high-pressure turbine to get miserly-fuel flow. This translates directly into range. Western firms have invested multi-billions in design and material-research to achieve efficient ‘dragsters’.
China and Russia have a problem. They can design huge engines with massive thrust. But they take more fuel-flow than Western engines to achieve this. So, their new high-performance ‘stealth’ fighters have more-limited range than Western versions. Ultimately, this makes them more ‘defensive’ fighters than having the range to take the fight to the forming-areas of an enemy.
Hence, the Chinese talking to the Germans. The Chinese have mastered certain aspects of producing the blades of the high-pressure turbine, but not other aspects. This is a ‘shopping trip’ to swap mastered technologies for un-mastered technologies. In a peaceful world, this would be win-win. In today’s world, not so much…
Firefox is in a battle/lawsuits with yahoo.
Firefox dumped Yahoo & switched to google as default.
i was hoping you’d have time to comment on this one. how far of a lead does amurican tech have over german, russo and sino? how does nippon figure into this. i remember way back when being amazed when boeing gave up their wing to china. figured they wouldn’t have done it if they weren’t way further ahead on design and production than what they’d shown us.
ZDB, American high-tech is generally of the highest levels in the world. It varies by category, of course. (Planes, yes. Cars, no.) Typically, cutting-edge systems are among the best, until the category becomes a commodity. Then, manufacturing moves to cheap-labor countries and cranking-them-out becomes the priority – and foreign techs take-over the lead.
As an ex-Boeing engineer, I would say that Boeing management sold-out Boeing workers and America in general. Boeing’s management embraced the “produce it cheaper overseas” model that has hollowed-out much of America’s industry. First fuselage segments and then wings went overseas in search of maximum corporate profit. American workers be damned…
The peak of this movement occurred with the 787, with Boeing involvement reduced to being merely a snap-together shop for large, foreign-built sub-assemblies like wing, fuselage, etc. This came back to bite them when several foreign firms did not prove up to the challenge. After sending Boeing engineers & technicians out to correct the mess, Boeing finally had to buy-up several of the foreign-owned manufacturing plants located within the US and ‘put things right’ at its own expense.
Since then, Boeing has been slowly drawing-back manufacturing to the US. It will be interesting to see how much of Boeing’s next airliner, the ‘New Midsize Airplane’ (NMA) or 797, will be produced in-house. Maybe Boeing has learned its lesson…
“They” sold out the whole food chain; from the low onto the high-end value chains.
It’s the small industries/businesses that supports the food chain’s infrastructure that really matters. Because, w/it your R&R becomes a strong suit in your economy’s future prospects. W/O it; your dead in the water, in more ways than one would care to count[despite our financial wizards making nothing into dollar$.].
Love the hoodie, Dr. Farrell!
