    Boeing reports wing cracks on Dreamliners

    Everybody makes mistakes. I am not familiar, does the Dreamliner have metal spars, or is this really a de-lamination or other composite flaw. I did not think composites would have hair line cracks.

    New Twin Aircraft Design

    Hey Guys, I wanted to get your opinions on a new safer twin aircraft design that me and my Professor have created and tested. It should eliminate all of the Vmc issues encountered in the "classic" layout of a twin engine aircraft. What do you guys think? Think this is something you would...

    Carbon Graphite AV8-B Harrier Spar

    Now I are an Enganeer but before that I was a Tool Designer, and had the pleasure of working at McDonnell Douglas on the tooling for the prototype AV8-B. At the time this aircraft was the largest Graphite Epoxy assembly ever made. I thought the site might like to see how the spars were...

    Aircraft Design: Synthesis and Analysis online course

    This isn't a book per say more of an online course. It does explain AC design at a college level for first time students so you won't be overwhelmed. Several sections you may want to pass and get to areas of interest. AA241

    Airfoil advice for unmanned aircraft?

    Hey there! First forum post, happy to be here! I participate in a an aerospace design competition in high school, and this year's challenge is to design a UAS for agriculture. The competition is based entirely on design (CAD etc), so we won't be physically building anything :( Anyways, I was...

    Foam Ultralight?- New Design

    Hi forum, I have been researching building aircraft for a long time and want an ultralight (can't solo- not old enough) but none of these airplanes are as strong as I would like or are too much. I have been also researching the design of my own and came up with a plan for a sporty looking, low...
