Boeing B747SP
I am considering this Baby 747 as my next model after S Constellation is done towards mid of this year, i want to power SP with twin DF engines, preferably OS 91VRDF with either Ramtac or Dynamax fan units. I like to know if anyone have good workable 3 views or scans from Boeing files. I want to make it as accurate as possible with all 10 yards. Thanks in advance.

I will load some 3 views today or tommorow
but I must warn you some parts of this
aircraft are copywrite protected and if
I was you I would not even use the term
747 especially in the forums...

Apart from center 3 views none others are needed as thay are not SP yet full size &$&s....
My search is on guys, let me know what you have.

"Duh" am I missing something here where did I put my glasses?
The SP side view is all that I have and I don't see a whole lot of people
posting 3 views heck I have a set of plans for this bird but I am sure you can do better have at it...

Richard,
This will definately work for side view as you mentioned and front view minus flap track fairings with extended H stab span and fin's height, but i need something far more detailed then this as i will have a friend do it up on CAD for me before plans are drawn, i also need cross sections for fuselage, wings, vertical stab, H Stabs and engine pylons.

RE: Boeing B747SP
The geometry of the 747 is proprietary to Boeing and is not shared with
the general public. However, Boeing many years ago did make the
geometry of the 747-200 available as a CFD testcase. The wing airfoils
are correct, but the wing twist and deflection is for a 3G loading
condition, not 1G, as would be seen in cruise flight. The airfoils are
far removed from any "classic" airfoil, so forget trying to find a NACA
airfoil that is close.
All airliner wings are composed of multiple airfoils, usually combined
in a splined surface. The basic DC-8 wing has only three airfoils, but
most other airliner wings are built up off of more airfoils than this.
The 707-120 wing has NACA 60-series thickness forms on modified 5-digit
camberlines. These airfoils are available at the UIUC airfoil database:
opus.aae.uiuc.edu/~selig/ads.html
Every Boeing wing since then has had custom airfoils. If you dig deep
enough, the 737 wing appears in a NASA report and what I think is an
airfoil from the 767 wing appears in another NASA report. I have yet to
find any information on the 707-320, 727, 757 or 777 wing in a public
source.

This is the CFD Testcase with some of the data:
http://aero-comlab.stanford.edu/Pape...0%20airfoil%22
Airfoil Designations can be found here:
http://www.ae.uiuc.edu/m-selig/ads/aircraft.html
However, the coordinates of the BAC (Boeing Aircraft Corporation AFAIK) are confidential and not released.
I seriously doubt that these airfoils would result in a well-flying RC model, since they were designed around very different parameters. Go along with simplified airfoils, possibly semisymmetrical NACAs or such.
I'll see if i have a set of fuselage cross sections on the 747 at home. I know i got the 737.....i'll get back to you on that.
best regards
Hank

Yes you are right on airfoils part, actual aircrafts are always different then what we can model, plus i am not going to use scale airfoils as my models is smaller lighter and not same as real aircraft is, i will use something on lines of semi symetrical airfoils and Naca airfoils to built my wing. But before i do that i want to work out single slotted flap mechanisum on the wing first, as i have learned on my current S Connie project that adding flaps, specially complicated types are not good to go after wing is built!, once this step is done then i will do thew wing and followed by fuselage. This project will start towards 3rd/4th half of this year.
Let me know about fuselage cross sections as whole tail plane and aft fuselage is very different on SP then any regular version of B747.

Sorry guys, didn't look at the top left picture as it is the short SP. I will get glasses. WHMC

.As for scale i am thinking on lines of 1/14th scale same as my Connie, most of the construction will be foam core and then glassed or i will do plug and mould ways to make copies also. I haven't decided build type yet as its still far off.
This is how my SP will look once done, this perticular SP is the only SP that i have ever traveled on, just couple times only.

RE: Boeing B747SP
Yo Tim he wants the short stubby version called the SP. I like the progress you have made, The motor Nacells look good you molded everything
except the wing and tail feathers, molded wings are in style you know and you instantly keep all of the scale panel lines
rivets etc. I cant wait to start building mine Im thinking BIG...

Hi concordefan
i dug out all the stuff. The cross sections are all for the -100 and -200 series of the 747. I always liked them better than the SLUF SP :-)

I like to heve 100/200 series cross section too for referance, forward fuselage is same on SP as other 747 varients, center fuselage and aft are totally different, so least i can get started on forward fuselage first and i am sure by that time i will get SP cross section also.
You can email these to me or if they are on paper then i'll give you my address. Thanks

Could I kindly get a copy of whatever data you might have. Especially those cross sections.
If it's all paper stuff, I'd gladly re-emburse you for your costs to mail it to me.

RE: Boeing B747SP
I am willing to commision a model resercher who can provide me as what is required to do this model accurately or if anyone have through reserched material to do SP then i am willing to pay you for your research to get the materials.
Thanks and Regards

RE: Boeing B747SP
As much as I tried I couldnt find much on the Sp . I reverted back to pics on airliners.net found a coulpe of pictures that I could see the panel lines on used them as reference to count windows to see which sections were missing.
I removed 30% at the front 10% in center 60% in the aft . By doing this I came up with Sp dimensions.
To discuss in further detail E-mail me offline [email protected]

RE: Boeing B747SP
Hi, I found some 3-views on Boeing's Website. After I unzip it, I could not open it with AutoCAD. any ideas?
http://www.boeing.com/commercial/airports/3_view.html
--------------------
Never mind... Looks like I need newer version of AutoCAD.
