Abstract:

A device for rapidly decelerating a high velocity projectile in a liquid ium, e. g. water, while preventing both excessive high inertial loading of sensitive projectile components and high impact loading of the device itself is provided. A plurality of deployment panels are released at a selected depth and initially opened by leaf springs and thereafter by water flow. Acceleration of the panels is controlled by a piston actuated by the panels which displaces water in a chamber in the drogue body through a suitable orifice.
