Just saw a documentary about hypercars. Pretty sexy senpai.

Shouldn't this be on /g/?

Bagger 288

>>7940329
why?

This is porn

Dreamliner 787 is a much better aircraft desu

>>7939852
Too bad no one wants to buy it

But still, A380neo when?

>>7939852
>no yoke
>not shit
pick one

>>7940770
>787
>a little over 300 passengers
>380
>over 800 passengers
Even the A350 is bigger and better than the 787. When the rich oil barons of the Middle East want to fly, they fly Airbus.

>>7939936
I bet that fucker has a pretty high Cd. Why the fuck would you make a car look like an old stealth bomber? The only reason the stealth bomber was trianguly, was because of computer software limitations.

>>7940783
>implying bigger is better
>implying I want to fly on the same plane as a bunch of Middle Eastern people

>>7940789
Hypercars aren't just about reducing Cd. They also have to create downforce.

Because it doesn't really fit into science and math.

>>7940789
>>7940815
Because you arent just trying to create as low a Cd as possible. They already know how to do that pretty well. Look at land speed racing vehicles. THATS low Cd for a car, pic related.

Road racing cars need to create aerodynamic downforce, to press the car down and allow for more traction. Also the cars need lots of airflow to cool various components, such as the engine and brakes.

>>7940783
>arabs have no taste or common sense. they just go with what ever costs the most and looks expensive.

>787 is revolutionary in design and materils.

>A380 is just big and conventional

I've been always more for Airbus, noice A350, but with new Boeing 787 and incoming B-777X and B737MAX will rekt the French company... well done

>>7940371
Because it's technology, not science.

>>7940792
>bigger means more seats which means more sales for airliners, plus it's technically impressive
>the fact that Qantas sucks Airbus' dick for new planes means that Airbus designs planes with passenger comfort in mind
What other metrics for best plane you want, senpai?

>>7941334
If you want composites, there's the A350. Not only would the A380 be hella expensive if made with composites, but it probably wouldn't be as good of a product overall. Only college freshmen automatically assume newer materials = better product

>>7941352
>tfw I work on the A350
>tfw I have to shill on my off-hours to make sure I still have a job a year from now

>>7941334
>>787 is revolutionary in design and materils.
Kek, boeing must really have low standard to call that revolutionary in design or materials

>>7941374
>replying to these sour grapes
I would bet quite some money that they're just burgerlanders who can't swallow the fact that the largest, most conformable and most impressive airliner isn't made by them, since they love aerospace for some reason.

>>7941374

Composites were incorporated into the 787 to reduce costs and boost efficiency. Unfortunatly, A380 is just a larger 747 with not a lot of innovation, but it does have economies of scale...assuming you can fill it up and have enough routes for it to fly. That doesn't appear to be happening and Emirates not committing to buying more planes means it won't get needed upgrades to make it competitive with other planes.

>>7941400

The 787 uses more composites than any other commercial plane. They had to come up with new manufacturing techniques to solve the delamination process.

>>7941417
>acktually
A350 is 53% composite, while the 787 is 50%

Don't get me started on manufacturing techniques. They are absolutely disgusting on both aircraft.

A380 was released too early imo. As the world's megacities continue to grow, and as flying becomes more popular and accessible, larger passenger aircraft will be necessary. Just not yet.

>>7941406
Thanks brother

Not even a debate, the UAE seems to be shitting on the rest of the world with their creations. The Palm is also insane

>>7940783
>>7941374

Except that the problem with the A380 is that it creates huge vortex wake so you have to keep them further from other planes, which can congest airports

It is a serious concern at Dubai's airport

>>7941453

>>7941126
>>7940815
I'll be that aesthetics were a bigger design concern for that vehicle than down force

>>7941453
Making cool shit is easy when you can literally dig money out of the ground.

>>7941126
nope, you dont need nearly that much material to create the dumbforce required especially for a car from a company that can't make a turbo without setting the car on fire

this is a triumph in engineering, hybrid powertrain, regenerative braking, all wheel drive, rear steering, and it shits out 900 horsepower out of only 8 cylinders. and it does this in a package weighing less than 1.7 tons

>>7941560
Too bad the engine's still in the wrong place.

>>7941445

>A350 is 53% composite

No kidding. It's like they learned their mistake and had to innovate to compete and give what their customers wanted. It's the reason why the A350 will eat away at any remaining orders of the A380. This will be for the better as they will make money on this plane and kill the unprofitable A380.

>A380 was released too early imo. As the world's megacities continue to grow, and as flying becomes more popular and accessible, larger passenger aircraft will be necessary. Just not yet.

Airbus bet on the hub and spoke model. Major cities connecting each other in large aircraft then having smaller regional planes. Boeing bet on people wanting more direct routes and thinking that eventually hubs would be constricted in size. I think Boeing had the correct model here hence why they didn't bother going bigger than the 747. Don't get me wrong if the A380 were cheaper to develop, it may have made economic sense.

>>7941453
Except the locals are just paying for it. They have Westerners and East Asians designing and running construction. While South Asians and various muslims are brought in as an indentured labor force. Thousands of foreign laborers die to build every sky scrapper or other attraction.

Note how it looks like a penis.
This is another piece of evidence to show us that Engineering is gay as fuck.

>>7939852
Project Apollo.

We need to upstage it senpai.

i like trains

>>7945060
Note how the train looks roughly like a penis.
Especially the front section gives off the impression of an uncut penis with the foreskin pulled all the way back.
This is yet another piece of evidence to show us that Engineering is gay as fuck.

Your penis locating skills are impressive.
I stand in awe

>>7940759

>TFW I got to see this beauty flying at the airshow in Tucson, AZ last weekend

Porn indeed, even more so when it's attached to the rest of the aircraft.

>>7942335
Looks like it'll be drones instead.
Or orbiters. the X-37s are intended to incline with aero maneuvering.

I don't like it either

>>7945165
I have located further penises:

>>7941455
If you pay attention, this artificial, manmade island also has a distinctive phallic shape.

>>7941453
This is a bit pointy for a penis.

>>7941126
Ahh, the penis car
A classic example of phallic imagery in engineering.

>>7940759
Pay attention to how this penis-shaped object spits a blue-colored substance.

>>7943269
it's...

beautiful

>>7943269
Niiiiice.

Doesn't include URD functionality like some more modern lifters, but adds four flying penises. Known in the gay Russian aerospace engineer as a Korolev cross

>>7939852
it's pretty mediocre
Boeing could make a bigger plane if there was a serious market for those planes. They are only needed at international airports with limited runway space.
It's very inefficient to use the 380 anywhere else.

>>7942335
They will never make it again. It was only a spy plane and satellites have gotten better.

Saturn V rocket FTW!

>>7945255
A giant penis powered by four auxiliary-penises
Russian Gay Engineering is truly the best in the world.

>>7945281
In less than ten years, we went from suborbit to the largest goddamn rocket ever that could send humans to the moon. Fifty years later and not even SLS can rival it. We shouldn't have retired the Saturn V in the first place. We were going in the right direction.

>>7945289
No we weren't. Human rating a cargo lifter that complex is nearly as idiotic as doing it again then flying inappropriate missions

NASA could have done so much more than they did but instead opted to tease Russians. Fucking pricks

>>7945563
To clarify, by "again" I mean the Space Shuttle.

>>7945281
>>7945289
That is an impressive penis.

>I'm 12 and I designed a car after watching Le fast and furious XD

It makes me think of the Spanish when they got the tons of gold from the new world.
They keep digging money out of the ground but all of the people who makes the things they spend the money on is from other countries.

Kind of an interesting parallel.

>>7941660
Looks like a flower in bloom.

>>7939852
>http://dataphys.org/list/gaudis-hanging-chain-models/
>Spanish Catalan architect Antoni Gaudí disliked drawings and prefered to explore some of his designs — such as the unfinished Church of Colònia Güell and the Sagrada Senpaiília — using scale models made of chains or weighted strings. It was long known that an optimal arch follows an inverted catenary curve, i.e., an upside-down hanging chain. Gaudí's upside-down physical models took him years to build but gave him more flexibility to explore organic designs, since every adjustment would immediately trigger the "physical recomputation" of optimal arches. He would turn the model upright by the way of a mirror placed underneath or by taking photographs.

>>7941453
The Burj Khalifa is really not that big of an achievement technically speaking.

Shanghai Tower is much more impressive from an engineering standpoint.

Fuck the Shuttle. It was still absurdly expensive like the Saturn V, but it had no launch abort and it couldn't go beyond LEO. We would be better off if we stuck with Saturn I for LEO and Saturn V for beyond.

The SLS is pretty shitty too. It will let us do a lot of the things that the Saturn V could do, but it's still really expensive for a very outsourced rocket. I'm sure Arianespace or SpaceX could do it better if we threw the money we're spending for SLS at them instead.

>>7947637
NASA likes to build Ferraris, when the mission calls for a Honda Civic.

>>7947648
we all spend more than we need to when it's not our own money we're spending.

>>7947637
>We would be better off if we stuck with Saturn I for LEO and Saturn V for beyond.
The point of the shuttle is that each president inherited it, and didn't have the political baggage of justifying a new disposable spacecraft for each mission.

>>7946316

There isn't even a single thing that looks vaguely phallic in that image.

One of the most important thing about technology. It doesn't get beautified, it doesn't get acknowledged, but it sure as hell gets a nod from me.
