Abstract
An aeronautical drogue having a canopy and support members connecting the canopy to a connector provides for essentially constant drag at variable speeds by aerodynamic pressure modulation through controllably venting the canopy by constructing the canopy of a plurality of separate elastic bands positioned side by side the elastic bands being connected at spaced intervals by flexible connections.
