Most airliners have wings designed to be used in low transsonic. They can't effectively go faster. They would literally lose lift if they went faster. Their wing shape is made to only delay the onset of shockwaves on top of the wing (flat-ish top), allowing it to safely creep closer to mach1 than otherwise, but not to operate within/past mach1.

Fan/propeller blades themselves are also mach limited.
(They can be designed to be supersonic, but then you end up with something like this... which in hindsight nobody wants : https://en.wikipedia.org/wiki/Republic_XF-84H)
A subsonic airfoil in a fan/propeller, operating near/at supersonic speed, loses the ability to move/redirect air, due to shockwave disruption of the airflow.

Fans/propellers with subsonic blades that spin at subsonic speeds are effectively speed limited. They lose efficiency above ~500 mph, where they begin to stop generating thrust as they travel faster. Their pitch has to increase higher and higher, until they are no longer much of an airscrew and more of a 'feathered' configuration.

Supersonic jet engines use intake devices (such as shock cones) to decelerate incoming air to subsonic speeds, so the compressor (itself a fan, i.e. a highly multi bladed propeller) can operate on that air to compress it and feed the engine combustion chambers.
Airliners have no intake devices to decelerate incoming air, and they would lose engine compression when entering near mach1 speeds.

Furthermore, their bypass fans (which are glorified propellers) would stop providing thrust.

You would need to design different planes (like the concorde). You can't just throttle up a modern airliner and go faster [than X limit] - like you can in a modern car.

I misunderstood then...apologies. I agree, there's no telling what he might do, he's a feather in the breeze. I'm glad to hear that not all Christians have been duped, contrary to how it's been portrayed.

I think you mean Dawkins admited Jesus WAS a real person, which I agree seems likely....but to come back and slap someone today means he's NOT a person, but instead is (choose one) immortal/god/zombie/clone/timetraveler.

A bird pooped on my Subaru there other day. I couldn't do shit about it, either, because the bird was way up in the sky. But his asshole must have been equipped with the Norden Bombsight or something, because it landed a pancake-sized shit right on my windshield. I think it was a seagull or something. I hate those damned things because they steal your fries down on the waterfront and land pancake-sized turds on your Subaru's windshield. John Oliver's right: fuck birds! I'm gonna find out where that seagull lives and take a shit right in its nest! "You eat clams, you feathered fuck? Well here's a CLEVELAND STEAMER for ya!" That'd feel so good, too: ironic revenge at its finest. What? Don't tell me that's not the correct use of ironic, either! I'll climb up on your roof and shit on YOUR Subaru's windshield, then blame it on a seagull. Don't think I won't, either.

Damn I love legal marijuana.

Bah. Walking around drinking capri sun with teenage girls in feather boas? That shit's just asking for moop. Virgin.

... as do our feathered friends

Our jack russell ate our fearless feathered leader :=(

Just a servant...nobody at all. I mean, we have a household with at least -three- gods, and -they're- afraid of the feathered one. What chance does a hairless ape have in that crowd?

Same fail point, I bet; overspeed condition with no ability to automatically stop the blades and turn them into the wind so that they don't turn too quickly and burn up (no auto feather, or auto feather parameters exceeded).

Could have been either a software failure or a hardware failure---or perhaps an unholy combination of both.

ok, i'll do my best:

"It's where the program does the animation for you using physics (or other) algorithms. As the artist, you place a "flag" in the scene, and attach it to a "pole" then tell the program there's a "45 mph wind from the East".
Then you hit "Play" and you get a movie of a flag waving in the wind."

this is called a sim, and yes it's a type of procedural animation but it doesn't replace some kind of "classical" method of animating. sims are used for all kinds of things: particles, cloth, fur/hair/feathers, crowds, fluid, rigid body destruction, etc, etc. the artists who do this are not animators, they're FX artists and it isn't as simple as plugging in "45 mph wind from the east". not even close. for something seemingly that simple you're dialing in things like direction, turbulence, gravity, plus the cloth properties. once you have your settings, you sim it, which can take days on a render farm for complex sims. if that sim is approved then it goes to lighting, gets put into the scene, has textures/materials/shaders applied, and then gets rendered, which can take another several days on a render farm depending on the complexity. these sims are the only way to get realistic animations for these types of materials. and there are generally many versions made at this stage to get the sim right, fix broken frames, fix intersecting, get the lighting and textures/materials/shaders working right, etc. THEN it goes to the compositing dept for a couple dozen more versions.




"As opposed to regular animation, which can be thought of as glorified stop-motion animation. Each single piece moved by you, individually, for each frame of video."

regular animation is like stop motion except it's not every frame (it's interpolated between keyframes) and is for character animation.

anim and FX are 2 different departments and often use 2 different software packages.

mocap is also not handled by the anim dept. it would be done by match move and/or tech anim.




"You create a flag and a pole. Then the next frame you bend it here, here, here, and here, then click forward to the next frame, and bend it a bit more here, little less here, invert this bend, add another, make this corner whip a bit."

no one in there right mind would do this, it's completely impractical, and would look like complete shit.




"It basically allows less technically savvy artists play in a world where only "nerds" used to play."

the FX people are way more nerds and technical than anim people. you need to be technically savvy for every dept. but the real nerds and really technically savvy people work on pipeline who were probably heavily involved in this project building custom toolsets for it.




"Really kind of lazy way of animating."

no, it's fucking hard, requires a lot of knowledge, a lot of people, a lot of cpu horsepower, is used all the time to get high quality animations, is a collection of several departments other than animation, and is used in conjunction with animation.

You don't think that Trump won't make an unfair system even worse? Do you know what kind of scam operations he runs? Read up on Trump University, and if you don't think a mind like his won't immediately start eroding the as of yet intact elements of our government, then I have a bridge in the bay area to sell you. Not to mention that Scalia is not my definition of 'bright' by any standard. Bloviating quasi intellectual douchenozzle, sure, but not exactly a contributor to constitutional scholarship.

Hillary will be a boring drag; an uninspired and predictable apparatchik, but not remotely as harmful as the narcissistic psychopathy that's absofuckinglutely going to get us into severe confrontations around the globe that a Trump administration would bring.

Think about it. Yesterday the Russians put out a sabre-rattling presser about a US destroyer in the Black Sea (its international waters). Under Obama or Clinton, I can be pretty confident that any ruffled feathers will be smoothed and that things won't escalate. With Trump, if he has a bad morning because the viagra didn't kick in on time, or Ivana talks back or whatever, god knows what his decisions would be.

He picked up a feather, duh.

I've upvoted, but this is a terrible explanation of why owl wings are silent. Owl wings move tremendous amounts of air: the idea that they glide to stay silent is hogwash. Owls wings and feathers have some incredible adaptations to reduce noisy air turbulence - there's a better explanation here: http://www.asknature.org/strategy/938e8c4d8e2bf786fa5c9922d181273e

I hope whoever picked this music was fired, dragged outside, molten led poured in their ears, tarred, feathered, and burned at the stake....but whatever, I don't have strong feelings about it or anything

So if she weighs the same as a block of steel...

...then she's made of feathers?
