>what are maintenance checks

>>567707

They probably leak like a sieve, like many aircraft.

>>567707

B-52s don't have any fucking windows along the side for cracks to form on.

>>567707

How about a fucking period, or comma faggot?

Look Pedro, I know English isn't your first language, but for fuck's sake give me a break. How am I supposed to read that OP, let alone comprehend and (provided that I do have the knowledge) provide an answer to it, when you don't even bother punctuating it or even sticking to the number one basic law of human communications that a string of words should convey the semantic gist of your idea to the other party of the message?

>>567883

This, please. Also I read in some other thread that we Swedes often come off as feminine in our language when writing English online, is this true?

Strelok, that's a pedophile.

>>567867

Fix'd.

>>568108

I mean, most of the class is either fresh out of the military or in their 30s (or both) so that point is kinda null. He might have been a faggot, though.

>>567707

Maintenance checks and reverse-engineered newly made parts. This is almost entirely what they do at Tinker Airforce Base in Oklahoma. Also yeah no windows meaning fewer stress concentrations and fewer fractures.

>>567720

The fuck is the point of going to school in your 70s?

Enjoying learning.

If you have the money after retirement why not? Signing up for one class a semester at a local uni sounds like an interesting way to spend time. It would give you a chance to cover the mostly useless subjects (e.g. Old English) you never had time to learn when you were young.

Since you wouldn't care about a degree, you can usually sign up as a non-credit registrant, which is cheaper and doesn't require you to actually get fully admitted to the university. You attend the classes but don't do graded assignments or exams.

On a related note, some Strelok once explained why US still keeps B-52s when they have B-1s and B-2s, but I forgot. So can someone explain it to me?

I mean, I understand that the US would want to keep its nuclear deterent without investing heavily in manufatcuring new planes, hence keeping the B-52s. Plus I imagine a B-52 costs less per flight hour, or maintenance than a B-2. But that wasn't his reasoning.

>>567707

That's because aircraft are subject to outrageous amounts of scrutiny and if anything as much as provokes an assumption of defectiveness, it is immediately replaced. That includes replacing chunks of airframe that look like they starting to age.

>>568263 points out some correct things about metallurgy and plane design, but is otherwise wrong. Aluminium is very prone to work hardening whereby it becomes stronger but also more brittle. And even if it wasn't, airframe parts being able to withstand a lot of pressure cycles isn't the reason airplanes can fly for decades.

>>568268

I did say it applies more to Steel than Aluminium. In any case, the graph I used shows a pretty substantial cycle count for Aluminium going into the 100,000s and above with relatively high stresses for said cycles. I doubt any planes currently in service have had nearly that many load applications regardless and, like you said, with proper inspections and maintenance these things can last for a long time.

>>568212

well, b2s are absolute shit, is one reason.

>Also I read in some other thread that we Swedes often come off as feminine in our language when writing English online, is this true?

What the fuck Sweden.

>>568473

Assuming he means accidentally using feminine pronouns or something

how do I tell if my aluminium spars are OK?

>>568462

Yes. That was basically the gist of his reasoning. But could you develop that point? Preferably with taking B-1s into the equation, too.

>>568304

His wording was fine, think before you type.

>>568605

Since when does strength equal hardness and not resilience?

>>568549

The B-1 and B-2 are both massive hangar queens. Back when we were mobilizing for Iraq the USAF estimated that we could only put 50% of our B-1s and 30% of our B-2s in the air at any given time, vs. 80% of our B-52s.

>The fuck is the point of going to school in your 70s?

Alleviating boredom while learning new stuff.

When I was in college I saw an tough old guy in uniform, I went and spoke to him to see if he was a speaker or something, turns out he was a retired Signal Corps Colonel with pretty cool stories to tell (dude was in comms HQ for both Kosovo invasion + initial Afghanistan invasion), that decided to get a master degree in history of the arts.

Because he liked that and why the fuck not?

>>568097

>Also I read in some other thread that we Swedes often come off as feminine in our language when writing English online, is this true?

It is.

>>568189

Learning is fun and helps keep your mind sharp, as long as you don't take retarded classes.

>>568618

Thanks for the reply. I also heard an argument once about how a B-2 needs to get refueled more times to get to russia than a B-52. Now, according to Wikipedia, a cursary internet search, and some back of the envelope calculations there seems to be some substance to this, but the difference seems to be not more than one time aerial refuelling. How much truth is in that?

>>568940

>stealth tanker drone

Those words should not seriously be used in conjunction to describe anything.

>>568940

That explains it. We had a thread about those stealth refueling drones a while back. So this also explain that.

Didn't notice my own Superhitler get.

Why is b-2 so expensive?

>>568940

>>568942

Theres's a thread on it here >>562211

>>568960

The stealth meme.
