My team and I are not in this years competion, so we decided to practice using 2011/2012 tutorials, but inside of PTC MathCAD, we are getting different answers as opposed to the design phase video.
In the Wing Optimization mathcad document, after inputting all the values from the video, we end up with...
semispan=320.76 in
tap= 0.8
dihedral= 1 deg
rootchord=40 in
semi_area(taper, rootchord, semispan, dihedral)=80.178 ft(squared)
But the video gets the values
semispan=352.07 in
tap= 0.8
dihedral= 1 deg
rootchord=36.443 in
semi_area(taper, rootchord, semispan, dihedral)=80.178 ft(squared)
We thought that because the semi_area was the same, we would get the same results as that appears in PTC Creo, but for some strange reason, our wing comes out as being twisted.
I am adding below our results so that you will have more data to help us figure out our problem.
((Sorry, I cannot show you our file with the wing at the moment, windchill is down for the moment. As soon as I can though, I will try and add it later.
