  • Samara wing
    Patent number: 8079546
    Abstract: A samara wing including a main wing with a leading edge and a trailing edge. An aileron has a leading edge and a trailing edge and is pivotally attached proximate the trailing edge of the main wing and separated therefrom by a gap. The aileron is rotatable between the first position where the trailing edge of the aileron is facing forward in a plummet mode of operation and a second position where the trailing edge of the aileron is facing rearward typically for an autorotation mode of operation.
    Type: Grant
