Most of the previous ...<B>I am an aerospace engineer.</B>. Most of the previous comments about ballast on airplanes are very misguided if not completely wrong. Here's the REAL reason ballast is used on airplanes.<BR/><BR/>Yes, weight DOES matter. However, what is just as important is drag (the resistance to moving thru the air). An airplane MUST have its center of gravity closely maintained so that it will be stable in flight - so it will not tend to diverge from controlled flight. Ballast is absolutely required for this. Additionally, while an airplane can be safely flown within a range of center of gravity locations, it will require some aerodynamic "trim" to keep it moving straight. This is usually done by adjusting the control surfaces. However, using controls to adjust trim adds drag - which means more fuel is needed for the engines to overcome the drag.<BR/><BR/>Many modern jetliners use fuel shifting to accomplish this center of gravity trim. So ballast is not needed dynamically - only when it is built. Bear in mind that most of the time, the passengers and baggage cause huge changes in balance, that must be countered.<BR/><BR/>Now, this is almost all beside the point anyway. The ballast being discussed here is really not related to balancing the center of gravity - it's related to balancing individual control surfaces on the plane. To prevent a control surface from entering a "flutter" state - where it violently oscillates back and forth, and potentially self-destructs - the control surface must have its OWN center of gravity balanced. Obviously a control surface is not a huge place to mount weights wherever you wish - so the denser the ballast material, the better. So this is the place in the airplane where DU is frequently used. It's not that large a quantity, and it's not in a location that is likely to be released, other than a crash of course.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10666456.post-1114763523738328602005-04-29T03:32:00.000-05:002005-04-29T03:32:00.000-05:00Well, I've never taken a survey instrument on a co...Well, I've never taken a survey instrument on a commercial flight, but those numbers from the graph seem low to me. I'm in charge of the dosimetry where I work, and I've had guys accidentally take their dosimeters on flights. Those dosimeters have all turned up exposures in the 100-200 mr range for a cross-ocean flight. That's about a year's worth of exposure around here.<BR/><BR/>I suppose they could all have put their dosimetry through the x-ray bag scanner as well. Maybe you could try slipping your detector through the bag screener and recording that to see what happens.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10666456.post-1114744468195508672005-04-28T22:14:00.000-05:002005-04-28T22:14:00.000-05:00I worked for the Boeing Co. from 1964 to 1966.

As one of its inputs it used a Giannini made angle of attack indicator which had a small amount of DU as a counter-weight to balance the vane which was outside in the slip-stream. There were two of these sensors on each 727. The total mass was no more than a couple of ounces of Uranium. These vanes were located close to the cockpit.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10666456.post-1114736624125052632005-04-28T20:03:00.000-05:002005-04-28T20:03:00.000-05:00Ed T says " Froskur - Make as much fun as you l...Ed T says " Froskur - Make as much fun as you like, but the fact is that commercial airplanes use or have used DU as ballast.<BR/><BR/>and offers this link<BR/><BR/>"Check out Not-so-Depleted Uranium (about half way down the page under the 'Not-so-Depleted Uranium' heading)."<BR/><BR/>I did check this out, and the site refers to a plane crash in Holland where, apparently, signs of DU were found at the crash site.<BR/>It goes on to quote members of the American society for Metals( website here:http://www.asm-intl.org/)<BR/><B>without</B> providing a link for the quote.<BR/>"The journal of the American Society for Metals explains that DU counterweights "are used in the aerodynamic controls of planes, rockets and helicopters to maintain the aircraft's center of gravity... in many civil and military aircraft."<BR/><BR/><BR/>Now, I don;t have access to the journal, but a simple search of the ASM site reveals <B>no matches</B> for 'depleted uranium"<BR/><BR/>It's hard to believe that they wouldn't have ever mentioned it at all if it was in their journal.<BR/><BR/>I smell urban legend.<BR/><BR/>Look, Occam's Razor says "planes do not need ballast."<BR/><BR/>even if we stipulate they do, I concur with the poster who suggest that far safer, nearly as dense metals would be used.<BR/><BR/>-AdamHollandohttps://www.blogger.com/profile/04047728914994591856noreply@blogger.comtag:blogger.com,1999:blog-10666456.post-1114729611238261252005-04-28T18:06:00.000-05:002005-04-28T18:06:00.000-05:00The exposure to the DU in Iraq comes fromthe vapor...The exposure to the DU in Iraq comes from<BR/>the vaporization of it when the shells hit<BR/>tank armor.

If they need to change the balance on an airliner they can shift gas between tanks. They also have little trim tabs on the wings that they can adjust to change the orientation of the plane in flight.<BR/><BR/> Airplanes cost more to fly as they get heavier. Manufacturers go to elaborate lengths to make planes as light as possible without making them weak. *Everything* that goes into a plane is scrutinized to see if it can be made lighter. Commercial airlines don't carry so much as one extra meal tray when they take off.<BR/><BR/>If for some bizarre reason they needed to make part of a plane heavier they would just use safe cheap lead weights, not expensive and hazardous uranium byproducts.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10666456.post-1114726878478938802005-04-28T17:21:00.000-05:002005-04-28T17:21:00.000-05:00Hi all,Not to put too fine a point on it, but the ...Hi all,<BR/><BR/>Not to put too fine a point on it, but the whole DU-counterweight-in-passenger-aircraft issue is completely overblown. Stop to think for one second - a 500 degree fire in the aircraft is going to be a much more immediate hazard to life than any amount of depleted uranium that might be emitted as a result. <BR/><BR/>As a certified industrial hygienist, I examine risks like this every day - "Where is the potential exposure?" is a question I ask frequently. Here, unless a catastrophic failure occurs, not even one photon of radiation from any DU is going to reach you, the passenger. Compare that with the cosmic radiation Dean observed with his toy G-M probe.<BR/><BR/>As for the DU ammunition stories that drift about the internet, I have no illusions that our government or military leaders have any hesitation to use weapons that present serious hazards to those who use them and those on whom they are used, But I haven't seen any evidence that even thousands of antitank rounds expended in Gulf War I can be tied to the horrifying natal deformities seen on some of the websites devoted to exposing this "crime". Even if we left hundreds of thousands of tons of DU in the deserts of Iraq, how are people going to be exposed to it? Where is the exposure? Are they burning it for heat and inhaling the fumes? In all likelihood, those deformities are caused by the starvation of the Iraqis facilitated by the US government.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10666456.post-1114724488271598532005-04-28T16:41:00.000-05:002005-04-28T16:41:00.000-05:00I'll make even more fun of the DU guy.I've fired D...I'll make even more fun of the DU guy.<BR/>I've fired DU rounds from an M1A1 tank, taken an "extreme" Nuclear, Biological, and Chemical (NBC) course, AND right before I left the Army they started giving ALL soldiers who may have a higher chance of coming into contact with DU special classes on DU fragments, inhalation of such fragments and whatnot. The SAME question was raised in a lot of that training about DU in airplanes.<BR/>The response?<BR/>"Not in civlian aircraft. Too risky." Of course, the Spectre carries a 105 main gun which is the same German-built gun in the older M1-series tanks AND is capable of firing DU rounds, but that would be expensive overkill I would think.<BR/>Now, if what you are saying is TRUE (I doubt it, no matter WHAT you "Google-find" on the Internet) then there would be radiation hazard teams at EVERY plane crash. Hmmm...I think the press would have picked up on that one since most of them are educated and would know a Geiger Counter when they saw it or asked "Hey, what is that?"Anonymousnoreply@blogger.com
