Abstract
A drogue assembly includes a probe guide such as a standard small high speed drogue with a first canopy (14), and a foldable second canopy (20) mounted around the first canopy which is biased outwardly, and is foldable inwardly under air pressure loading to overlie the small drogue at low speeds. Thus the drag produced by the drogue varies automatically with airspeed allowing the assembly to be used over a wide range of airspeeds.
