737 Shell Dimensions AutoCAD

[Michael Carter]

Here is a bit of information I dug out of a Boeing 727 reference guide I have.

Each station on the airframe is measured in inches aft of the datum point.

The the 727's case the datum point is 130" in front of the aircraft. This is how long the flight test probe extended out in front of the aircraft during testing. The tip of this probe is '0' inches.

The very tip of the radome is 130" back and is called station 130.

From the radom tip to the the very aft of the #3 window frame is station 259.5. If you subtract 130 from 259.5 you get 129.5" or 10'-9 1/2". This is how long this part of the cockpit section is. Each of the ribs has a station point aft of the datum plane. This only has to be subtracted from the nose datum point and converted to feet and inches to get a measurement.

This will even tell you the spacing of the ribs under the windows as each has a datum reference.

This information is near worthless without addition data from a plan view with the same station identifiers, and a front view as well, but it is interesting to me.

Incidentally, the entire cockpit section as an assembly as mated to the front half of the fuselage goes to station 348.2, just aft of the left side entry door, or 18'-2 13/64"

Sad considering quote, 'By giving measurements to anyone other than a simulator manufacturer, we are putting the Boeing Company at risk'.

I'm guessing even if we formed a simulator manufacturer company we would be contractually bound to keep that information confidential. I'm wondering... if someone came out with the CAD drawings (providing them commercially or not), would Boeing push for a cease and desist?

That's the thing I'm looking into at the moment. It could happen like you said that once a sim company becomes contractually bound with Boeing, not only would they not be able to distribute the measurements, but possibly even mention them. Boeing is very tight about things like this and I'm sure Airbus are alike.

hey guys,

You can douwnload the shell dimensions in autocad. They are in my profile ->douwnloads. More cad drauwings will come.

HI thanks for all you have shared, but unfortunately, I don't see the cad file with the shell dimensions in your downloads folder anymore. Any chance you can re-upload/provide this?

Thanks!

I would be interested too,

Thanks in advance,

Downloaded yesterday, great drawings ?

Hello I am new.However I know there is a cad measurement around.I saw on the "Portuguise 737 project" it is so simple its not funny...its just a paper cut out that you trace onto plywood and cut and bingo you have the ribs or stations,however I need the measurements so i can do the same. I dont know how to work with CAD but does anyone have the cut out paper stencils??Dont throw them away,we can buy them ???
Kind regards Faleolo

I understand that Mike at the Portuguise 737 simulator project has them but I am unable to communicate with Mike.Its simply an extraction from CAD then drawn to scale on paper,then traced onto plywood to cut the stations or ribs.If you see his video its brilliant but how do you extract the measurments from the computer??? only Mike knows that.Not sure if Mike is on Mycockpit but its a great idea as its all exact

Hi Raymond,

Its Norman from Faleoloo.Is what you downloaded the shell cockpit CAD drawings??? What site do you go to to to this?
