I think its absolutely unquestionable that french engineering sucks bc the french revolution killed off the smart rich ppl
The world's tallest fucking bridge is in France 🇫🇷 , your theory has been debunked. 🇨🇵🇨🇵🇨🇵🇨🇵🇨🇵🇨🇵🇨🇵🇨🇵🇨🇵

Saying this is like saying the best skyscrapers are in dubai. Are you trying to say that the architects of the dubai skyscrapers are from dubai? Kek

I said tallest, can you build a taller bridge?

The French aristocracy wasn’t in place because they were smart. It was the polar opposite of a meritocracy which kind of fueled the entire thing. They sure as shit didn’t kill off all the brain power that is literally the stupidest take I’ve ever heard and not substantiated by the historical record on any level at all.
How about the best selling commercial jet of all time?

The A320 was primarily designed by British and German engineers. It also includes parts from everywhere between the US, Britain, Netherlands, Germany, France, Japan, Italy, and more. The aircraft are assembled in France, Germany, China, and Alabama. I would not say it is a French plane. Nothing from Airbus is really a French aircraft, as it is truly an international conglomeration of a company.

Many of the OG Airbus engineers who pioneered the a300 program were french, like betille (sp?) and zeigler. Was referring to this rather than the 320 specifically.

Ah. Yeah i should definitely read more into the history of Airbus as I would like to possibily work for them someday. Living in Toulouse would be lit because I think Airbus is becoming a much better company than Boeing and Europe aligns with my green vision of the future more. More importantly, it's only 2 hours from Andorra and 8ish from the Alps with tons of resorts and amazing backcountry

Being from Seattle I feel like I have to rep boeing, but man do I feel like they've fallen off the cutting edge of engineering. Such a bummer
That sucks I was looking forward to debating the French Revolution with the guy on the bus that thinks he is Napoleon but just shit himself trying to light a crack pipe
ReturnToMonkeyI love Boeing and their aircraft especially but the business leaders of the company completely screw over the engineers
Seems that once they merged with McDonnell Douglas they transitioned from a company driven by engineering to a company driven by finance. Moving HQ to Chicago, squeezing another generation of aircraft out of a 50 year-old airframe, etc. Will be interesting to see what they come up with for the “797”.

Welcome to 90% of engineering jobs. These days, most companies think marketing > engineering. That's because companies are run by businessmen who think business, not products. They forget that good products sell themselves. Instead of investing in the R&D of good products, they spend their money cleaning up the messes of rushed launches and improperly tested parts. The most successful companies invest in developing good products.
That's my rant as an engineer who works under short-sighted executives.

Boeing merged with MD because they couldn’t effectively land government contracts. When they merged the culture shifted to be more profits driven because the profitability of government contracts is significantly higher than commercial programs. Also Dennis Mullenburg (CEO who presided over the max crisis) fucked us over in a bunch of different ways. He was primarily responsible for the shift in engineering culture within the company. Trust me, the engineers here want to do design new stuff but the company is happy to keep building stuff off of antiquated platforms.
ReturnToMonkeyCan I ask what you do there? And why do you hate Airbus (unless its just rivalry, that makes sense ig)
I’m an Electrical Design Engineer, feel free to DM me if you have more specific questions, I’m not going to post anything else publicly. Yeah the airbus thing is just rivalry lol, they make solid stuff. I do prefer Boeing though because there’s a strong heritage here though. I’ve gotten to know some older engineers who’ve worked in every part of the industry at every company. It just seems that a lot of these engineers have gravitated here over the years. I worked with a guy who was a part of the golden age of the NASA X program and worked on the XB-70, another guy was a former space vehicle engineer for the Shuttle Program, and other programs such as SR-71, F-15, and others.The people I’ve met at this job are by far the coolest thing about this company.

OMG SOMEBODY CENSOR THIS POST QUICK BEFORE PEOPLE SEE IT!! THIS IS HATESPEECH!!!
DingoSeanDude you have gotta stop it with this weird ass obsession...
I coudnt find the original thread i made about this so i assumed it had been deleted with the other one. But when it comes to the world trying to convince itself that government can be substituted for the free market, statements like the one made in this thread simply cannot be heard enough.

Agreed it’s like it just turned into constant drama with the machinists, they started outsourcing to fuck the union over, 737s started crashing themselves it was an unmitigated disaster through and through with Boeing the last couple decades.

what does that have to do with your weird ass nerdy obsessions you wont shut up about...
CabbyArrantI’m an Engineer for Boeing. I’m disappointed at times but I still hate Airbus

I had a question i asked on reddit that didnt get answered that i hope you might have thoughts on.
What are your feelings about the design move of rolls royce to make hollow fan blades on their latest models of turbofans? I felt that it was an incredibly stupid move because solid titanium (what they used to use on fan blades) is very durable and heat resistant. Also i assumed tolerances would be tight enough on a turbofan that apart from a fractionally slower blade acceleration rate (due to the rotating mass being a little bit lighter) there would be minimal frictional energy savings because, like a perfectly balanced load in a washing machine spin cycle, the spinning of the spools would not benefit significantly from being a little bit lighter due to hollow fan blades.

Anyways im curious to hear your thoughts.
The phrase in the middle of my second paragraph:
“apart from a fractionally slower blade acceleration rate”
should have said:
“apart from a fractionally quicker blade acceleration rate”

disclaimer: I’m an electrical engineer and I’m not really familiar with RR engines but I’ll give it a go.
I can see three main advantages to this approach.
1.) A hollow design could be more friendly for additive manufacturing. Turbine blades of any sort are incredibly expensive to produce so additive manufacturing methods are attractive to minimize material losses. GE I believe has been working on this concept for some time. A hollow fan blade would use significantly less material and time to produce in this method.
2.) The weight savings could be pretty significant depending on how many stages of the compressor utilize this technology. While you are probably right that a reduction in friction is probably minimal the real benefit in my mind is the possibility for a faster spool up of the engine. That increase in acceleration from lighter blades could improve the spool up time of the aircraft when the pilots add power.
3.) cost over the life of the blade. I would imagine the cost per flight hour for the hollow blades would have to be significantly lower or this approach wouldn’t be taken. There’s also the possibility that in the event of FOD in the engine the hollow blades would cause less collateral damage to the rest of the engine and the reduced risk of uncontained engine failures if fins broke away.
Like I said this isn’t really my are so take my answers for what they are. Guesses

Those sound pretty reasonable. It was just kind of the way i thought about it that if would be like using tin instead of steel to build a skyscraper. Like even if it does the job and saves money, do you really want anything but the best and strongest material to hold up your skyscraper?

Honestly though with modern FEA tools it’s possible to create structures that can be as strong as solid materials. ULA does this with a lot of their fairings where they machine billet aluminum or steel down to create the fairing with a specialized lattice structure that makes them insanely strong.
