RE: Airliners
 

Personally I find these airliner models more impressive that the fighters that we normally see. I guess part of that is due to the fact that they are pretty rare.

RE: Airliners
 

Ya, , , they are rare indeed, especially the expertise of this kind of builder!

The overall cost would just skyrocket if you go turbine. But I don't see much problem with ducted fan either. So back to what's making these airliners rare? It's probably a lack of good technical research because I think typical 3 views stuff just doesn't cut it.

RE: Airliners
 

I would say not what I'm looking for these are station drawings without cross sections needed for scratch building. Good referance if your working on the actual ship with X,Y and Z locations but for our needs they are not the best. In my case I already have the airframe design size and location of the big parts. I close up of the skin panel locations would help with panel lines and fastener rows. I am also looking for the wing fillet detail, gear doors, nacelle doors and latches you might have that on the bottom center and right one but I can't read anything on them with the size re-produced.

RE: Airliners
 

I guess you missed the part that there's at least another 10 more or so drawings, with tons of everything etc. Maybe what you really need is a bunch of good walk around photos since you already have a model.

I'm sure you know what you want, but are you aware that those station lines are also the panel rivet lines that your looking for. The frame stations have a 90 degree flange that the panelling is riveted to. Measure off 4 foot sheets and there's your panel outline, complete with all the rivets within. Panel sizes basically only change at the cockpit and aft of the pressure bulkhead.
Having those station lines makes it real easy to rescale for any size model. But I mean real scale, not stand-off.

Here's what gear doors look like. Notice the station lines on this drawing. They not only tell the exact size of the door, but also the exact placement on the aircraft. In this drawing, it's made even easier because it's drawn at true 1/4 scale.

Anyways , no problem charlie, your project is comming along very well . . . .
I won't bother regenerating those additional 10 drawings then. It's probably another 50 feet of paper to go thru, and move on to what I was working on.

Merry Christmas

Actually, having the stations available for your particular subject like Mike Emilio has posted would be beneficial to the scratch builder if you are familiar with the process of Lofting.

The 757-200 pictured was totally drawn & scratch built at 1/16th scale from three views & pictures.

RE: Airliners
 

Oooooo, now that's nice. I'm drooling!!!!!

RE: Airliners
 

Thanks Mike...I'll relay the appreciation on to my friend who is the designer & builder. The one pictured above was #3 while the one pictured here is #4 and the one currently flying. While these are powered by IC engines, it would be a good candidate for the 12-14 lb. class of turbines.

RE: Airliners
 

#4 !!! holy crap they're beautifull !

RE: Airliners
 

Yup...#4

Here is a short video clip. Needless to say, the landing gear mounting platform has been perfected. :) Nervous thumbs and a little pitch sensitive make for not such a pretty arrival.

RE: Airliners
 

Love airliners......just a little pricy, when you have to get 2 turbines ;)

RE: Airliners
 

Simply awesome!!

RE: Airliners
 

You don't have to get two. Rauch's 727 is designed so that a 20 lb. thrust turbine will fly it. It is situated in the tail similar to the L-1011 of PCM.

You guy's in Denmark are doing some great stuff. I think it shows that if your not lazy and looking for a ARF you can build some neat Models. Butch

RE: Airliners
 

Hey Butch, unfortunatly, they are not from Denmark :-)

Most of them are from Germany, and the 757EDF and DC-9 pusher prop, are from the US I believe.
All the german ones are from the Nobert Rauch foam/glass kits

RE: Airliners
 

Sorry ! My BAD ! Who ever built them,their neat. Butch

RE: Airliners
 

Mike I did see that you have a lot more than shown, Still interested in finding the one that will work for me. Thanks for showing us what you have so far. Your right the Y stations locations are in inches from the nose and do show exact location and size.
I have first hand experiance with those flanges and fasteners I drilled and filled for 5 years on the MD-80 cargo before going to the MD-11 rigging cargo doors. The window belt had it's own skin that was pretty long between splices, as you know not every skin panel started ontop of a station frame some had splices (4 rows of fasteners) between the frames, even more of them in the MD-90, 95 and 717 because they went to a barrel join method like we always used to join the nose to the fuse. With my project I am using a book "Douglas Jetliners" it has a few great close up shots I have used for airscoop and cockpit window ridge shaping.

RE: Airliners
 

Gluing on the new parts today first the tailcone was attached with plywood reinforcement to help with alignment, tack glued then cloth tape and epoxy was brushed on the interior. Then I aligned the pylons and used the same process with tape and epoxy adding a little cabosil to the remainder of the resin and filled the outside gaps on both pylons and tailcone. That will sit overnight before attaching the nacelles. The west system epoxy is used through out so far.

RE: Airliners
 

Those are all really amazing planes :) !!!

I wonder one thing... does anyone know what wing profiles are used on those birds to get good flight characteristics with those wings??

regards
Chris

RE: Airliners
 

On my MD-80 I believe it uses NACA0009 that's fully symetrical. I think they are prefered to a flat bottom or semi symetrical airfoil so they can be landed at higher speeds without stalling. No high lift wing is needed, a pattern plane airfoil would be a good choice IMHO. I know a guy that tryed using a flat bottom airfoil on an FJ fury that worked fine with a DF but with a turbine it idles way too fast to get it down safely even flaps and speed brakes don't seem enough. With that airfoil it needs wing spoilers to kill the lift. In the picture I have the same airfoil for the pylon profile drawn before cutting the hole in the fuse side.

RE: Airliners
 

Thanks charlieoneseven! The turbine speed is what I did not consider... I am myself only working with glow engines (no DF) on a very small airfield, so speeds are some dimensions smaller, and therefore the profiles must be different. I still stick to the NACA 2415 / 2412 and TNT which proofed to do a great job on Warbirds (Bombers...) and similar planes. But I still wonder if somebody can tell me what profiles are used on prop driven jet airliners with swept wings??

regards

Chris

RE: Airliners
 

You can ask the designer if you like since his airliners are designed for props too.
http://www.rauch-airliner.com/MD-80E.htm this is the one I am working on it uses 2 7.5cc glow engines as well as turbines or DF.

RE: Airliners
 

Anyone knows where I can find good 3 view drawing for A319???, I am planing to start building one for two turbines:D.
