Nastran/Patran are quite different to Matlab, they are FE modellers/Solvers whilst Matlab is more of a high level program language.
Some universities do utilise Matlab as a tool during the Aerospace/Aeronautical course, for example for flight mechanics and aerodynamics. It is actually quite...
that is neat, i soo want one :)
"quadrotors use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor."
Certainly a interesting read, i do not have any substantial to add, however you have a few "[Error: Reference source not found]" throughout the copy posted.
I guess the main thing I took away from it was that unless environmental control (particularly moisture) was implemented throughout the...
I have it in a old RAAF engineering handbook and its listed as Mild steel BS 2T.26 Weldable Tube 20 Ton. It has according to this hndbk, tensile strength of 44.8 ksi and yield 24.6 ksi at soft condition.
Not what I would call definitive, but if you want a scan copy I can always shoot you a copy...
Ed, thats a handy calculation for clips and flanges which are on the marginal side, cheers! Can you advise on which design text/manual that attached file is extracted from?
I would head down the direction that MiketheEngineer mentioned, check out others who have restored these aircraft, I am not sure what country your in but the first place I would contact for info about the catalinas would be the Historical Aircraft Restoration Society Inc (HARS)(see...
Check out the proposed FAA Memorandum Memo No. ANM-115-09-XXX 'Policy Statement on Flammability Testing of Interior Materials'
It contains alot of good information regarding the flammability requirements which may help in your case.
Below is the Summary;

Nordam should be able to provide you with something! at the very least the;
Long Beam Flexure, “L” Direction Skin Stress, psi
and Climbing Drum Peel in-lb/3-inch width
I have got some specs out of them for 610-10233-500 and similar but not the numbers you quoted, they are pretty slow at...
bf109g,
That study/video was probably:
DOT/FAA/AM-07/13
Office of Aerospace Medicine
Washington, DC 20591
Assessment of Injury
Potential in Aircraft Side-
Facing Seats Using the ES-2
Anthropomorphic Test Dummy
It is a very interesting read, let me know if you can't find it in the public...
you have named all the ones we use!, MDsolids (I use an older version which works well) which is great for simple quick sections, any more than that I move to AutoCAD or Pro/E, both of which are very quick once your used to it, although that said, AutoCAD is a bit painful with the region and...
Try Traceparts, they can provide fittings, parts etc in many formats including solidworks. From what i can tell, alot of their parts are manufacturer specific.
http://www.traceparts.com/
Of course they charge for this service but they do have a fairly good aircraft hardware selection now...
smesajar,
yes thats right...after a bit of research i came up with this:
note the 'a+' - to append to the existing file
fid = fopen('file.txt','a+');
fprintf(fid,'\n');
fprintf(fid,'%9.4f',var1,var2,var3);
fclose(fid);
fprintf is very powerful function - can generated very nicely formatted...
anyone know how to add data to an existing data file.
ie, i have a data file and i want to add a new line of data (matrices) to the file.
i have looked at the save -append option but that overwrites existing variables and can only be used on .mat files (i think), i am using .dat files...
