lecture 3 (wing geometry) v1.1

project 3 (wing loads) v1.0

A very rich lecture and an interesting, if rather unsuccessful, project. See my commentary about this project on my blog.

Many improvements, indeed far too many to list here, were brought to the slides since they were first used in class (v1.0).

Media used in these documents:

• Several photos by the generous Vincent Edlinger (on Flickr, on Airliners.net)
• DR400 photo CC-by Wikimedia contributor Huhu Uet
• An-124 photo CC by-sa Wikimedia contributor Antti Havukainen
• An-124 planviews Olivier Cleynen, derived from public domain by Wikimedia contributor Mo7amedsalim | Wikimedia contributor Malyszkz
• Elliptical lift distribution figure is a quote from Bertin 2008 (not an extraordinary book but rather solid) (this figure should be re-drawn and freed!)
• Spitfire photo, Dash-8 photo Public domain by the remarkable Wikimedia contributor Adrian Pingstone
• 767 photo edited from CC by-sa original by Flickr user bobbinguy
• 787 photo CC by-sa Flickr user adpardo (lost photo source)
• Wing box figure, Fuel tanks figure CC by-sa Wikimedia contributor Tosaka

The following photos would be in the slides if they were free... I tried to purchase these shots to put them on Wikipedia but could not get in touch with the photographers. Any help getting in contact with these people would be very appreciated.

• 747 contrails revealing trailing vortices by Josef P Willems
• 747 lift distribution through condensation by Tim de Groot
• Tu-154 swept wing box by Adek Onesiak (lost source)

Documents I created that I then published on the Commons:

• Airfoil nomenclature figure

Documents I created that will be published on the Commons later this year:

• Expected and real lift distributions figures
• Visual explanation for circulation (unsure about copyright status)
• Trailing and starting vortices behind glider
• Induced downwash figures used in lifting line theory demo
• All wing shape diagrams (unsure how to publish)
• Principle of the dihedral figures
