firegate writes "The New Scientist is reporting that the US Air Force is planning to test a variant of the Wing Warping steering system used on the original Wright Brothers plane to steer new supersonic jets. They've invested $41 million in the project so far, and the first test flight will take place next month at NASA's Dryden research center in California."

Test speeds. (5, Funny)

Jade E. 2 (313290) | more than 11 years ago | (#4309674)

From the article:
The technology will be tested at subsonic and supersonic speeds, though not in the unpredictable range close to the speed of sound.
Now, I'm no aerospace engineer, but how exactly do you test at supersonic speeds without at least passing through the range of speeds 'close to the speed of sound'? Or, if the wing snaps in half as it passes mach 1, do they just say "Oops, that didn't count, better not tell anyone."?

Re:Test speeds. (0)

Anonymous Coward | more than 11 years ago | (#4309688)

Easy..they don't start measuring until the airflow is supersonic. Also they probably use different wind tunnels and models.. I've seen a supersonic wind tunnel that was a few inches in size and the model of the plane was a teeny little thing. Apparently this works just fine. I think it's assumed the wing won't snap off as it passes to supersonic..............they hope anyway..........

Re:Test speeds. (5, Insightful)

Ma$$acre (537893) | more than 11 years ago | (#4309699)

INAE either, but "passing through" and "[testing] in" are two different things. Going through the sonic barrier and testing within it are two different things. Going through is stressful... testing on the edge of mach 1 introduces amazing stresses. Something that flexes a lot more than a standard wing could set up harmonic vibrations which would shatter the hardware. Passing through would actually stablize after the initial shockwave.

Re:Test speeds. (1)

chamenos (541447) | more than 11 years ago | (#4309774)

it seems to me that testing the wings at speeds "close to supersonice" would be necessary, since the plane would first have to get past that speed before it can go supersonic, right?

what's the point of having a flexy-wing plane that can fly at supersonic speeds, but becomes unpredictable, or at worst uncontrollable at the speeds it has to pass through first before becoming supersonic?

i'm guessing if they can't get the plane to fly properly at speeds close to the speed of sound, they can probably use this technique on surveillance planes which need to be able to loiter around in places longer, since the lighter weight would help with fuel efficiency.

what's the point of having a flexy-wing plane that can fly at supersonic speeds, but becomes unpredictable, or at worst uncontrollable at the speeds it has to pass through first before becoming supersonic?

I would guess they have an actuation mechanism which makes the wing like a normal wing when active and softens it otherwise - so they can fly through the turbulence point

Scaebor (587064) | more than 11 years ago | (#4309844)

I suppose you could test it in a wind tunnel so as to minimize the outside factors involved. But still, you can't go from 0 to > mach 1 without passing the area around mach 1...

Re:Test speeds. (0)

Anonymous Coward | more than 11 years ago | (#4309964)

mach(t)=1-e^(i*t) goes from 0 to 2 as t goes from 0 to pi, without passing through the area around mach 1.

Re:Test speeds. (0)

Anonymous Coward | more than 11 years ago | (#4309952)

I AM an Aero Engineer (or at least an undergrad) and the difference is that subsonic systems have flows purely below the speed of sound and supersonic systems have flows strictly above the speed of sound.
When you pass the speed of sound (transonic), you have both, and you have mixed flows which add several variables and orders of complexity to the situation. This is the unpredictable region they talk about. It's not without bounds, and empirical data, but it's just not ggod for experimentation.

I think I actually read something about this in the Air Force Times (you can pick one up on most military bases). There is usually so much propoganda in there that its nothing but slop but sometimes they have something interesting. This is one of the reasons I got out of the AF, they spend all their money on R&D instead of paying the troops what they deserve to get paid.

There are Airmen (E4 and below) that make almost nothing and are in charge of thousand user networks, or several million LOC systems. It drives me crazy.

Volunteer until otherwise declared in times of war. When the draft is enacted, then the government conscripts all hale males of proper age. Males are required to register for the draft when they turn 18. The whole thing's rather sexist. If women want equal rights, then they should bear equal responsibility for the defense of those rights.

Re:Air Force Times (0)

Anonymous Coward | more than 11 years ago | (#4309998)

yes....feminism is my pet peeve. they're just a bunch of hypocrites and bigots, in my opinion. and this happens in almost every country with a "modern, western culture". in other countries like singapore which practice conscription, all males aged 18 have to serve two and a half years of "national service" after finishing junior college or getting a diploma at a polytechnic, whilst all the women get to go on to university and enter the workforce two to three years earlier than the men. and they STILL complain they are being discriminated against.

they argue that childbirth is kinda like "national service", but they fail to see that childbirth is not compulsary, and the government even gives monetary incentives to women who have children. "national service" for men is legally compulsary, and failure to do so is a criminal offence punishable by law, which usually constitues the archaic practice of caning (yet another "privilege" reserved for men in singapore only) and a jail term.

one of feminist's favourite feel-good topics is when they managed to gain the -privilege- (i wouldn't call it a right) of voting. i say it is a privilege, not a right, because the burden of defending the country, and hence that right to vote, comes saddled with the right to vote. do women have to do -anything- at all to earn that right? nah. during times of war they just hide out in shelters and consume valuable resources whist the men go out and risk their lives defending them and the country.

currently, singapore is suffering from a falling birthrate, and very soon the length of "national service" served would be extended to 3 years, to make up for the lower intake of new recruits, so as to keep the current pool of active servicemen the same size. and this is due to the failure of women to serve their "national service" of childbirth, with us men having to bear the cost. basically we're doing their NS for them. and whilst we sacrifice more of our precious time of our already-shorter-lifespans, the women go out and further their careers, earn more money for themselves, and enjoy the peace and national security that men pay the price for.

with the rather recent 911 incident, more men were called up for service to beef up the security due to the numerous US interests here, whilst the women did nothing. and i don't want to hear crap about the women who in the military, since those women joined the military of their own accord, and were not conscripted like men are. all they did was read about the various measures that had been taken to ensure the security in singapore and gawk at the men in uniform with guns, whilst they remained shielded from the reality of what it takes to ensure our security. the men in the meantime, got burnt in the sun, crawled through the dirt, and risked their lives to protect their country, its security, and to preserve the peace, all for a bunch of fucking ingrates who still whine they're being discriminated against. sad to say, most politicians think more with their balls, rather than their heads, and let chivalry take charge of their judgement. not only that, they know women's votes count a lot, and that those votes go against them should they ruffle the collective feathers of women. most women who have the right to vote, do so without knowing the full extent of the responsibility they have been accorded, since they never had to pay the price for it. its kinda like giving a kid a gun; the kid doesn't understand the responsibilities that come with the ownership of a weapon, same way women don't understand or appreciate the responsibilities that come with being given the right to vote.

to them, its a right they have, not a privilege. same way the british people felt the right to unconditional welfare was their right. to try and explain to them the intricacies of why being allowed to vote without having to defend that right to vote is a privilege and not a right, would be as futile as playing music to a bull and expecting it to appreciate it (a chinese saying). give an inch and they take a mile. and don't expect to get that mile back.

what has been made of women as a whole is nothing less than an aristocracy, and this has permeated so many countries and cultures to the point where it cannot be ignored, though it still is for the most part since feminism is still politically fashionable. and what is politically fashionable is what gets the votes.

with the recent campaign against afghanistan's harsh taliban regime, a lot of attention was given to the discrimination that women faced. that i cannot deny and i fully concur with the sentiments against it, but i have to say that the opposite is true for america and singapore (and numerous other countries which practice conscription to a certain extent). men are the ones being discriminated, and i find it ludicrous that the discrimination men face is still unspoken, and our tolerance of it is expected.

down with feminism!

kryonD (163018) | more than 11 years ago | (#4310050)

Sorry to pop your bubble, but E-1 to E-4 pay ranges from $1022.70 to $1752.30 per month depending on time in service (dfas.mil [dfas.mil] ). This is on top of the fact that all your food, housing, electricity, water, trash, medical, dental, and training are provided to you free of charge. In other words, the only financial obligations you have are the ones you create yourself. Even if you take a loan out on a car($300/mo. + $100/mo. for expensive insurance + $50/mo. for gas/upkeep), get a cell phone ($50/mo with a ton of minutes), and get cable plus wide-band access (up to $100/mo) that still leaves over $400 pure spending cash for even a boot E-1. Average promotion times are 6 mo. to E-2, 8 more mo. to E-3 and an average of 18 months for E-4 depending on how good of a worker you are. Most folks straight out of high school with little to no work experience usually don't have it nearly that good. Also, starting Oct 1st, the Military pays 100% tuition assistance for undergrad education, so free college to boot!

Now, that being said, the military is still a tad behind the civilian world in overall fiscal compensation. But it's a bit too far to say that enlisted make "almost nothing". As far as the IT field goes, most military people suck up the free training and bail after the 4 year stint for better paying jobs. This rapid attrition rate allows those that stay in to reach the ranks of E-5 and E-6 faster. Benefits begin to increase in the form of priviledges which makes staying in just about as worth while as getting out.

FYI, the daily unclassified, non-critical networks that the E-1 through E-4's usually administer have terrible up-time rates and is usually directly attributed to the lack of experience and education. Most of these self-proclaimed IT wizards couldn't manage a Nintendo without their roomate's assistance.

Before the blasting starts, I enlisted 9 years ago and have worked my way to the officer ranks. I think I made plenty of money then and make plenty of money now with the increase in pay directly related to the increase in my education level and responsibilities.

wing warping... (5, Informative)

tanveer1979 (530624) | more than 11 years ago | (#4309694)

There is a very intersting applet [nasa.gov] about wing warping on NASA site.

Actually wing warping was discontinued due to the fact that as modern airplanes became bigger and heavier rigid Duralium(Aluminium+Copper) and steel was used, which was not very conductive to bending, But I guess with carbon fibre based materials that will change.

Wing warping gives a large degree of control. It is Demostrated very well in the java applet which shows the lift, the forces, the mechanics and the attitude on a model plane(like the one used by wright brothers).

You obviously didn't see the pictures someone else posted. It uses a a pair of hydraulic cylinders attached to the ground [nasa.gov] , of course.

Actually (speaking with no knowledge of what I'm talking about) it seems like all you'd need would be front and back hardened rods the length of the wing that were only attached at 2 points - the [electric/mechanical] actuator inside, and a hardpoint on the twisty end...

Re:Where is the "oomph?" (2)

spun (1352) | more than 11 years ago | (#4309902)

It sounded to me like it was changes in airflow brought on by a modified control surface. Rather than seeking to deflect enough air directly to alter flight characteristics, the control surfaces would deflect enough air to bend the wing, which would then deflect even more air, and alter flight characteristics more efficiently.

I doubt they will be using the Wright brother method of having the pilot swing back and forth to bend the wings, though it does conjure up amusing images of combat pilots dangling beneath their supersonic planes.

A little history... and a further resource (5, Informative)

DaedalusLogic (449896) | more than 11 years ago | (#4309719)

We are a little over a year away from the centennial of powered flight. The Wrights made their first successful powered flight on December 17th of 1903. The first run was something around 12 seconds... Later in the day they recorded durations of just short of 1 minute. The wing warping technique was used to control the roll of the airplane. The Europeans later developed the control surfaces known as ailerons to get around patents that the Wright Brothers had made on their wing warping technique. Ailerons eventually became the method of choice for future development for many engineering reasons.


An article on this matter was published and graces the cover of the September 2002 Aerospace America magazine. The plane this system is being tested on if not intended for is the F-18, the writer of the article was J.R. Wilson. Aerospace America page at AIAA.org [aiaa.org]

The Slashdot Effect: A new form of terrorism.

Version 1.0 by Anonymous Pancake

As an assistant member of the security team of a large fortune 500 company, I have discovered a new form of terrorism stemming from the deepest underground of the Internet. A site catering to hackers, communists and anti-Americans called Slashdot.org has created a new type of denial-of-service attack known as 'the Slashdot effect'. This attack has been used against what are seen as the enemies of the 'Open source movement' which include many large American companies such as Microsoft as well as many American media companies such as Time-Warner-AOL. The Slashdot Effect could have a potentially crippling effect on the American computer industry and I feel it is justified to offer my own advice on this problem.

What is the Slashdot Effect?

The Slashdot Effect (also known as Slashdotting) is a new form of denial-of-service attack stemming from the site Slashdot.org. Once they find a 'target' (whether it be a large media company or small personal homepage) the URL of the site is posted on the front page of Slashdot.org. Members of this site attempt as quickly as they can to follow these links and overload the target server. This causes the 'target' website to slow to a grinding halt before going offline. It can sometimes take days or even weeks for the site to recover from such a surge of traffic, and often the servers can be damaged beyond repair (that is, they cannot be fixed with a simple defrag!).

Who is normally the target of the Slashdot Effect and how is it done?

Many American companies have already been attacked by the Slashdot Effect. Targets often include news sites such as the New York Times as well as well as large American companies such as Intel. Sites that criticize the open-source movement are a prime target. For example, lets say an American media website such as the London Times does a review of a little known operating system known as Linux. Linux is an operating system developed by a hacker from communist Finland, which is based on code stolen from an American operating system known as Unix. It was created in cooperation with a communist group known as g.n.u. (Which stands for Glorified Novelty Unix) and is generally unusable by non-hackers. Obviously since it is such an archaic and unstable operating system compared to those made by American companies such as Microsoft it would get a bad review on the London Times. Once a Slashdot member discovers this honest review the URL would be posted on the front page of Slashdot.org. A flood of users would follow the link to the site and bring the server to a grinding halt. Since most of these users are terrorists they would probably have ads disabled using European hacking software. This would mean a potential loss of thousands of dollars worth of ad revenue. To top it off, members of Slashdot.org often plagiarize the articles and post it on illegal mirrors, furthering the loss of ad revenue. Members of Slashdot are rewarded for plagiarizing in the form of 'Karma', a form of hacker currency, on Slashdot.org.

What can I do to avoid the Slashdot Effect and how would I deal with it if it happened?

The easiest way to avoid the Slashdot effect is to refrain from posting anything about any open-source software, especially Linux. Focus your website on fine American companies such as Microsoft. You can also set up your server to reject any links from Slashdot.org, something many people have done. If you think your site is being attacked by the Slashdot Effect, contact the authorities immediately and report this act of terrorism. The penalties against hacker/terrorists are stiff and you can feel confident that the perpetrators of this terror will be punished in the harshest possible means.

Good luck and God bless America!

It is a controllable surface (2)

aibrahim (59031) | more than 11 years ago | (#4309724)

and that means that they can choose to keep it "straight" or more like a traditional wing during straight and level flight as the aircraft accelerates through Mach 1.

They do this simply by controlling the deformation and setting it to the rest state of the surface...since this is a prototype of a very new technology it is fair to assume that aside from deforming the wing for control the actual shape of the wing is very traditional, as are its construction techniques.

This should give a reasonably predictable set of behaviors at transition.

Then again, IANAAE. I should perhaps be heeding my sig.

lol. Yeah, for the swing wing, but what I meant was the automatic adaption of the shape of the wing itself for different speeds.

Re:uh...excuse me... (0)

Anonymous Coward | more than 11 years ago | (#4310061)

Those tests were just to determine the effect of changing camber on a wing rather than extending flaps, etc. If I remember correctly, both board & starboard wing moved at the same time and they were hinged at various points so the individual wing boxes kept their shape.

Have been wondering how they warp the wing without buckling the skin on one side.

Re:uh...excuse me... (1)

Mac Degger (576336) | more than 11 years ago | (#4310064)

Well, for mision adaptable wings, look no further than the f14 or the Tornado. But then again, those where nowhere near as flexible (excuse the pun) as what's being talked about here. You might actually want to read the article.

The briefing at the base this morning (0, Flamebait)

PD (9577) | more than 11 years ago | (#4309789)

We won't know if these planes are any good until we can do a double blind study to see if these new planes can kill people more efficiently than the older types of planes. Of course, it's a bit difficult to do a double blind study, because it would require the people killed to actually not know they are dead! Taking care of the researchers is easier; we can hire a bunch of those civil war re-enactors to pretend to be dead (or not!). Well, since it's hard to do a proper double blind study, we'll just have to settle for several single blind studies and work some magic with statistics.

Anyone got a problem with that?
NO SIR!

Variable Wing Geometry in Anime (4, Interesting)

Guppy (12314) | more than 11 years ago | (#4309818)

In the Anime OAV Macross Plus, the General Galaxy YF-21 [geocities.com] Prototype piloted by Guld Bowman used a variable wing geometry as part of it's design, a feature also incorporated in the production VF-22 Sturmvogel [geocities.com] appearing in Macross 7. Of course, the mechanism is different in that (besides being fictional), a shape-memory alloy was used to allow the wing to change shape.

Pilots are still the limiting factor (4, Interesting)

mike3411 (558976) | more than 11 years ago | (#4309840)

Advances in maneuverability are great, but pilots are, and have been for some time, the limiting factor. The current generation of fighter jets can produce G forces that greatly exceed what even well-trained humans can endure. I think the next major advance will be fully remote fighter jets. If the military had some sense they'd be using cameras on the jets and some kind of vr for the pilots. Voila, war is video games, and all of a sudden I'm an elite fighter pilot!
And my millions of hours logged in Counter-Stike are merely preparation for remote-controlled human-like spec ops. Yeah....

Re:Pilots are still the limiting factor (1)

panurge (573432) | more than 11 years ago | (#4309965)

Remote controlled fighter aircraft? How easy is it to jam a radio? Line of sight communications would be too short range. And what about mountainous areas where the signal can suddenly interfere or go to zero?

You'll have to control your aircraft from above using satellites. And before long countries like India and Pakistan should have the technology to deliver the EMP bombs that will knock them out.

Re:Pilots are still the limiting factor (1)

mike3411 (558976) | more than 11 years ago | (#4310056)

How about short range radio supplemented by LOS communication via smaller, guided-missle style craft, which communally are capable of providing constant (encrypted) communication. I suppose, however, EMP would be an issue, but would they be in any worse shape than current fighter jets, whose control system is entirely electronic?

I remember a few years ago seeing in Janes Defense Weekly and other publications about a F-111 testbed vehicle in which the forward edge was replaced with similar techology. While this experiment did not include the entire wing the technologies developed were a definite precursor to the technology presented in the artical. If anyone else remebers this plane please reply, it is possible I have the aircraft type wrong. In an end note I have to say very cool reapplication of sound technology.

Old stuff, new twist (3, Insightful)

Chris Johnson (580) | more than 11 years ago | (#4309919)

Aeroelastic is old. That's the way 747 wings were built, and 707s, the entire pedigree of Boeing swept-wing jets have aeroelastic wings. They use the podded engines to direct the bends of the wing so that they are bending in useful ways. Non-useful ways would include flutter and pitching up in a stall.

What's being talked about here is DIRECTED aeroelastic wings, even more elastic than the Boeing jets. Sounds like a neat idea :) sure as hell would result in control surface effectiveness! Not only no control surface gaps, but the whole damn wing's a control surface. In addition, this could also trim the wings to act as flaps, changing wing incidence on the fly.

Re:Old stuff, new twist (1)

Mac Degger (576336) | more than 11 years ago | (#4310077)

Not strictly true.

What we have here is you not really understanding material science: everything bends when it's put under stress.
What you're talking about is just using the structural shape to minimize the stresses. Same thing happens in any structure (at least, if you're an engineer, which I am). You compute the forces, then the stresses and then devise ways of minimising them. That's not aeroelasticity, that's just elasticity, something you takee into account in any calculation.

Second bit of your statement is true.
