NASA's Dryden Flight Research Center web site contains a large gallery of photos and technical material on most of the aircraft that have passed through that facility over the years. The X-33 is one of those that is looking to the future. If you haven't visited this site before, make sure you click here and spend some time browsing around this facinating arena. |

This is a link to the San Diego Chapter 14 EAA home page. There are a lot of things on this page, but of particular interest is the Newsletter section and the Computer Corner prepared by Rik Keller. He takes a simple approach to each of the subject areas so the average builder can use the material without any difficulty. He also includes some downloadable files of Excel spreadsheets you can use for performing design calculations and performance evaluations. |
