Re: [RCSE] albatrosses

RVC - Original Message - From: tony estep To: soaring@airage.com Sent: Thursday, November 29, 2007 7:06 PM Subject: [RCSE] albatrosses The Dec 2007 National Geographic has a neat article on albatrosses. These soaring birds have spans up to 11 1/2 feet and cover as much as 500 miles per day, using dynamic soaring techniques to gain lift from the wind gradient above the waves. The article's description of how it works is not quite accurate, but the pictures, drawings and info are otherwise very cool. If you haven't thought about albatrosses since you read the Ancient Mariner in high school, this will be an eye-opener. -- No virus found in this incoming message. Checked by AVG Free Edition.

Mark, If I am correctly deciphering this comment (you're trying to get a more permanent hinge than tape or monokote provides) something I'm about to try on my latest center panel spoiler may help. I'm going to lay the spoiler in its bay and sand a 1/32 deep by 5/16 wide low area in both the top forward part of the spoiler and the wing just ahead of it. Then I'll carefully and lightly epoxy in a continuous strip of 1/2 wide sheared 0.75 oz kevlar (like it's prepared and used for the hinge in the BD - full length of the spoiler) in the low areas and two pieces of 1/32 balsa on top of that. Sand to contour when cured and you're done. Who knows, maybe it'll work. RVC The one piece central spoiler is a slab of ribs if I can figure out how to keep the tape sticking on the hinge.

Re: SPAM OSRELAY [RCSE] Subject:
Hello Anker, As far as I know, Mark Drela came up with the concept and introduced it for modelers on his Allegro Lite and then later used it on the Bubble Dancer as well. As I understand it the idea was to eliminate drag from intersections between vertical and horizontal surfaces (there are no intersections with this approach) and to eliminate drag from leakage through gaps between poor fitting horizontal stab members and the vertical stab. Check out... http://f6.grp.yahoofs.com/v1/oMyAPxaCj7xUnQ6n-3u4-99PTvz-Zc7jB_3g1KdyXvZGk7LtvFen6cHxOURGbmY-fQJ_KXDyjvITOadc3mHuWMWS6UCel8R0fBGjmg/Bubble_Dancer/bd_vmount.pdf That'll get you to a PDF in the folder for the Bubble Dancer files within the Allegro Lite site. The form to build the actual V on is not particularly difficult to make. I make mine from poplar planed and then sanded to shape. The form for the platform onto which the stab is mounted is somewhat more involved but still doable. I make it out of poplar as well, using multiple pieces glued together. I hope this helps. Let me know if I can add anything further. Regards, RVC I'd love to see how to build one, and then try it. Anker --- Outgoing mail is certified Virus Free.

Re: [RCSE] Paint information. Safety cautions!
Interesting stuff here Jason - thanks. Many years ago I was an automotive painter, sometimes using Imron and occasionally a respirator. If they had suits to wear I never heard of them. Maybe that explains why I only made it to structural engineer and not to aeronautical. Have you any idea what long term symptoms may be for unfiltered Imron use? RVC Imron type of paints, along with 2 part LPUs cure by chemical and mechanical bonds. The particle size is extremely small, and flows really well. The reducer is combined with a small amount of Isocyanide harder and mixed to the pigment for Imron/PPG/Acrylic Enamels, and LPUS are a 2 part harder/pigment as well. Extremely small/thin layer, great coverage, etc. DANGEROUS. This stuff is soo small and the reducer is REALLY bad because it takes the isocyanide with it as it evaporates. So you get a bad vapor that is not filtered by any mask. Can be absorbed by the skin, etc. You /can/will die if exposed directly, and many get very sick just handling the stuff. Sanding, etc can create noxious gas as well! Fresh air respirator is minumum protection. Positive pressure suit is reccomended.

I know there are a lot of full scale guys in this group and so hope you don't mind the temporary off-topic deviation. Thanks. RVC RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] FAI timing
OK we're talking about hundredths here. I may be revealing gross ignorance here, but how can some guy holding a stopwatch hope to be accurate enough for hundredths of a second to be considered? RVC At 08:07 PM 8/9/02 -0700, you wrote: OK, it appears as if we're carrying timing to the tenth of a second for F3J. But does this mean we're rounding the hundredths? Or truncating?

Re: [RCSE] Fun with epoxy
I have a can of 206 Hardener in my hand and it says, 5 parts 105 Resin to 1 part 206 Hardener by volume or weight measure. Hope this helps. That's weird. That means that the resin and hardener have exactly the same density. So it would seem. RVC --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

Re: [RCSE] Fun with epoxy
Yes, you are missing something. Frequently, the two parts of an epoxy resin system are not the same density, and the ratio that is correct by volume is totally incorrect when used by weight. I have also used systems that required ratios so lopsidded that weight was the only choice, such as 100:1 or 200:1. Here it easy to add 1% by weight to the resin, but if you pour this 1% into a container, and then add it to the resin, you will leave a lot on the walls of the container. True indeed. But as the question that started all this specifically addressed West System epoxy, and as the instructions on the West System can clearly state 5 to 1 by weight or volume, one can safely conclude that the densities are the same (or very close to it) and use either method.

Re: [RCSE] Ford Long Shaft Starter
(We need to start thinking about alternative motors). I've wondered about this. I'm currently rebuilding my longshaft winch after about a 17 year absence from the sport and got to wondering why we couldn't just use a normal (shortshaft?) motor with with a pulley to a belt to a shaft forward of the motor with the drum mounted to it. Seems to me they used to do it this way many moons ago when I last flew. Maybe a little more complicated mechanically but perhaps offset to a degree by the availability of newer motors. Have the longshaft winches become standardized? RVC --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

Re: [RCSE] decribe a discus launch??!!
Yes indeed! I'm new at this too and was glad to come across this site last time it came around. What impressed me most about Joe W. (aside from how well he piloted his plane - stalling just as he caught it) was how much energy he puts into his launch! Really looking forward to getting my first DLG built and in the air. Many thanks to whomever compiled all those clips. Rick Van Clief Brian, For movie clips, go to this page (recently posted in another message): http://www.silentflyer.org/ihlgf01.html Go to the bottom of the page and take a look at some of the QT clips. The second Joe Wurts clip shows a nice catch and release. Maybe some of the more experienced DLG fliers can tell us which clips show the best examples of form? --- Outgoing mail is certified Virus Free.

Re: [RCSE] OFF TOPIC - VIRUS SOFTWARE
Many thanks to all who responded to this. RVC Hello group I see once again virus are making the rounds. I got one off this group a while back which pretty much shut me down for a week. Ended up having to re-install my OS and almost everything else to get back up. The virus and one preceding it got past my up to date Norton Anti-Virus. Now that I'm up again Norton won't let me reinstall, and even if it would Norton only provides fresh virus definition files once a week or so. Question is, what's the best out there? I've heard there are those that allow one to renew definition files every hour! Is there a consensus??? Thanks. Rick Van Clief --- Outgoing mail is certified Virus Free.

Re: [RCSE] Flap wiper material
Years (many) ago I used to use 35mm black and white film developed without having been exposed. Kind of a hassle but it worked well and usually had a curve to it from hanging up to dry while weighted at one end. Had an opaque gray tint to it which looked kind of neat contrasted with some colors of Monokote. RVC Howdy, I am attempting to resurrect a plane that had nice flap and aileron wipers in the past but now are toast. Where can I get some new curvy wiper material?

Re: [RCSE] Merry Christmas
Good grief, where are you? I'm in central Florida and the high today will only be in the 70's. Rick VC To all you guys in the other world (northern hemisphere) having hot meals, celebrating Xmas with family indoors because it is cold outside I would gladly sit outside your window right now. It is over 102deg F (39C) at this moment and humid. I want to lay in snow and have ice clothes. I guess I can't complain too much though it is over 110deg C (44C) in other parts of this state.

Re: [RCSE] Dodgson Designs Gliders
Sorry about my last. Hit enter too fast. For me, has to be the Maestro, mainly because it's the only one I flew. Pretty plane - sure looked good in a Florida thermal. Had trouble keeping the wings in one piece, though (my fault of course). Rick Van Clief I am checking to see if anyone has interest out there in Dodgson Designs gliders. Bob's airplanes were VERY inovative in there heyday and can still be great TD ships. What was or is your favorite Dodgson glider?

[RCSE] LIFTROLL curves (cont.)
Thanks to all who responded to my LIFTROLL curves question earlier this week. I tried to thank each off-line. If I missed one, sorry and thanks. Several commented that the thing to do was go for max av/max Cl, and also that the Cl curve was helpful to determine if tip stall was going to be a problem. A follow up question then is what does the curve look like for a healthy wing and also for one with potential tip stall problems? Many thanks. RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Aerodynamic washout
Excellent stuff here guys! Thanks to Oleg for the original question and thanks to the rest for the really informative discussion. Rick Van Clief - Original Message - From: Mark Drela [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, December 18, 2001 12:42 PM Subject: Re: [RCSE] Aerodynamic washout Generally speaking any type of washout is not the ideal approach. Washout is used to compensate for bad planform design. I have to disagree here. For a given tip stall margin, a slight amount of washout (1 degree or so) allows using a stronger taper. More taper has all sorts of advantages for structure, inertia, wetted area, and low-speed induced drag. The tradeoff strongly depends on the type of glider. On a RES ship the importance of low yaw inertia is overwhelming, and the significant washout/taper combo is very attractive. An F3B must do very well in the speed run at near-zero CL, and little or no washout is more important. A TD aileron glider is somewhere in between, but closer to the RES case I suspect. And washout doesn't automatically kill penetration. It's just necessary to make sure that the tips stay in the drag bucket at the highest design speed. This is quite doable, especially on a poly wing where the tip's dCL/dAlpha is effectively reduced by 5-10% by the local dihedral angle. With any type of washout you are only optimized for 1 condition. If you fly faster or slower than that optimum condition you will pay a penalty in efficiency. Having optimum efficiency sounds nice, but it's not the bottom line. The bottom line is L/D at some given speed, or just sink speed. With 1 degree of washout, the span efficiency at high speed, maybe CL=0.05, might be down to 50% or whatever. But induced drag is less than 1% of the total at this speed, so you're paying a measly 0.5% overall drag penalty from the horribly non-optimum spanwise loading. But the washout allows you to taper the wing more, and the drag reduction from reduced wetted area (i.e. increased loading) can easily overcome this penalty and then some. And again, the main requirement is that every spanwise station (the tips in particular) is in its drag bucket in this high speed condition. - Mark RCSE-List facilities provided by Model Airplane News.
