Overview
The F.V.D. Doris or Dresden Doris, later known as the Akaflieg Dresden D-B2 Doris, was a monoplane glider built in Germany in 1922. It was unusual in having wings which could independently adjust their angles of attack, a feature intended to increase the energy acquired from gusts of wind.
