Ehang184-chinese unveil new passenger drone prototype

EMPIRE says...

"Absolute safety by design"

- open props and the passenger has to pass between them to get into the cockpit. all it takes is a false ignition or some other mistake after it lands , and the person is cut in half.

- drone design. just one of the 4 engines fails, and that shit drops to the ground like a brick, because it has no gliding properties and it can't autorotate like a helicopter or gyro, and at the height it will operate, I doubt a parachute would be of any use.

yeaaaahh... Not really anxious to try one out

Airplane Etiquette

StukaFox says...

They forgot these:

- Cabin service so frosty it makes a Moscow winter look like fucking Maui. (See: Icelandair)

- Fist-swinging free-for-all trying to grab aisle seats near the front of the plane (See: Southwest).

- The prepaid-for seat shuffle where the seat you reserved three months ago gets taken from you and you're reassigned somewhere near the head at the back of the plane. (See: Alaska Airlines)

- "Aww, Sweetie, did you want a sandwich on this 7-hour trans-Atlantic flight? THAT'LL BE 30 FUCKING EUROS PLEASE. Oh, you want to pay in dollars? Ok, that'll be 45 bucks at the current exchange rate plus conversion and transaction fees. Here, enjoy this three-day-old reindeer meat sammich that's dryer than the twats of the frigid cabin crew who served it to you." (See: Icelandair (again))

- Ladies and Gentlemen, we apologize for the 6g maneuver our former Air Force pilot is about to pull in order to avoid having to do a go-around because we were too busy discussing the new stewardess' tits to watch the glide path. Please keep the screaming in terror to a minimum as he startles easily . . ." (See: Delta)

- "Ladies and Gentlemen, we've now arrived in Scranton . . . oh, fuck, this isn't Pittsburgh!" (See: Delta (multiple times))

Yeah -- I just LOVE flying.

One of Those Days 2 - Free Skiing with Candide Flovex

Esoog says...

I love snow skiing. To me, it is one of the most freeing activities I can ever do. Just gliding down a mountain, back and forth...OK. must find mountain immediately! But I can ski 8 hours in a day and never do anything remotely as cool as what I just watched.

The pinnacle was at the 2:35 mark in the video when he does a backflip, and there is what looks like an Eagle flying over his head. Awesome.

Space Needle Aerial Footage

PlayhousePals says...

*dead removed by user ... guess he got discovered. From King 5 News in Seattle July 24, 2014:

Seattle's iconic Space Needle is still standing after police received reports of a drone crash at the popular tourist attraction Tuesday night.

The Seattle Police Department Blotter says witnesses reported seeing a small drone buzz around the top of the Space Needle and possibly crash into an observation deck window. Witnesses said the drone - described as a white quad-propeller unmanned aerial vehicle equipped with a camera - then glided to a nearby hotel, where it landed inside a fifth floor room.

Police said no damage was found at the Space Needle.

Investigators tracked the drone to a guest staying at the hotel. The man told police he flew his drone past the Needle, but claims it didn't hit anything. He showed video from the drone's flight, which showed people waving from the observation deck but no collision into the Needle.

The man told police he was an Amazon employee visiting from out of state and had bought the drone at a hobby shop. After police educated the man about Seattle's recent drone-related controversies, the guest agreed to not fly his drone again during his visit to Seattle.

Who knew metal milling machine could be such fun?

vex says...

I work in a CNC machine shop programming lathes. That isn't aluminum they are machining. It's definitely steel, probably 4340.

Carbide inserts are more than capable of cutting metal without coolant. Well formed chips absorb and carry most of the heat away. You start to run into problems with gummy materials (like aluminum) that form a built up edge on the cutter. In this case high pressure coolant can be used to help break the long stringy chips and keep them from sticking to the insert.

One case where using coolant can be detrimental to tool life is when machining a part with an interrupted cut. Think of sliding your finger over a surface with a bunch of holes in it. Your finger switches back and forth between making contact with the surface and gliding over empty space. In the machining world, this motion would cause abrupt transient temperature changes, and coolant can sometimes exacerbate the problem and cause the carbide insert to crack or chip.

(pedantry) I would hesitate to call that machine a mill. You can see the machine switching freely between rotating the part to provide the cutting force (turning) to rotating the tool (milling). It's more akin to a horizontal turning center with a milling spindle built in as well. Pretty awesome stuff! (/pedantry)

Not quite risky enough rail grind (cable grind)

kceaton1 says...

The fact that he made that little loop at the end just so he could dramatically decrease his altitude rather than just keep on gliding tells me that this person was extremely skillful and knew full well what they were doing at every moment.

Not even remotely close to being snuff, and I think the camera added to the effect of making some of those moments *seem* like they were closer calls than they ever were...

The Closest Mankind will ever get to flying like a Superhero

shveddy says...

Ski jumpers do it too, but with less airspeed:

Anything can produce lift (anything that isn't a sphere), some shapes are just more efficient than others. With practice, you kind of turn your body into an airfoil shape and with the perfect angle, enough speed and inflatable baggy pants you can get about a 1.4 glide ratio (1.4 meters forward for every meter downward).

It's an incredible feeling that is completely different from wing suits because your movement isn't restricted at all.

How do these work? They don't seem to have nearly as much surface area as the usual wingsuits.

Plane Loses Power Cockpit Footage

chingalera says...

Maximum glide ratio 10:1 in that aircraft (Jabiru J170 ultralight) only weighs 705lbs empty. Pretty safe plane to lose power in I'm guessing, better so than a small tear in your hang glider??

* wings?

Guy films juvenile kestrel in the backyard when suddenly...

carnivorous says...

I need to get myself a rifle! Fuck the forest creatures. Who would rather see them frolicking and gliding merrily through the forest than laying in bbq sauced pieces on their dinner plates anyway? Who gives a shit about the furry babies and the young birds that are left behind to fend for themselves and that will likely die because their Mothers didn't make it home? They're only animals.

I'm curious. Are you by any chance in the military and would you feel the same sort of rush from shooting a person?

shang said:

the thrill of the hunt. It's fun, not only does it provide food, it's exhilarating. Stalking the target is the most fun style of hunting large game, as you have to stay down wind, stay quiet, and get close enough for a good shot.

it is "getting off" so to speak. The adrenaline is pumping, it even has a name you can google "Buck Fever" every hunter gets it. "Buck Fever" causes a lot of missed shots, the heart races, adrenaline pumps and you wind up missing or spooking them. But hunting is a ton of fun, if it weren't my kids wouldn't even be interested in it either. Not only does it provide cheap and plentiful food for family, which otherwise I would probably need food stamps to afford meat for family of 4, it's also fun, entertaining, and constantly trying to get better.

Similar to how fps gamers get addicted to keep getting better scores and "kill streaks" same for hunting, I hate missing a flock of quail, I love when we flush a flock of 5 or 6 quail and we can get them all, which rarely happens, usually 2 or 3 are dropped until next flush.

if hunting was not fun, there would be no point, just buy from store...
but it serves a purpose and it's fun as hell.

Nice apartments for cheap...what's the catch?

Tree-climbing pro, Nat Geo photog gets shot of a lifetime

SevenFingers says...

I think it's a perfect touch to the picture, It seems to me the eyes would first look at the bottom left hand of the frame, then glide up the branches to the bird, then following the horizon to the right side branch, bringing your eyes down and to the left. Completing the circle.

spoco2 said:

Yeah, the concept is fine, it's the execution, framing and composition. The mist looks nice, the colour is nice, the bird is in a great pose, but there's so much uninteresting frame at the bottom, and the right side.

Craziest Glider Low Pass Compilation

rich_magnet says...

1) Water is ballast. It makes them more efficient when gliding, but they dump it to lighten up for landing.
2) Gliders are tougher than they look. Look into glider aerobatics some time. They also need to have flexible wings as the wings are so long.
3) The one in the dirt is presumably an "out-landing" - one that didn't make it back and needed to land where it could. The spin? (Hopefully) aerobatics.
