Abstract
The subject of the invention is a translational braking device for a projectile during its trajectory comprising at least two airbrakes that are radially deployable so as to increase the projectile's aerodynamic drag. Each airbrake is a flap pivoting around a pivot integral with the projectile and parallel to its axis. The device incorporates at least one pyrotechnic piston locking at least one of the flaps in its folded position and at least two flaps are stacked one on top of the other when they are in their folded position, at least a first of the two flaps incorporates a mechanism to retain the second of the two flaps in its folded position.
Claims19
A translational braking device used during a projectile's trajectory comprising at least two airbrakes that are radially deployable so as to increase the projectile's aerodynamic drag, wherein each airbrake is a C-shaped flap having an abutment heel and an end that pivots around a pivot integral with said projectile and parallel to its axis.
A translational braking device used during a projectile's trajectory comprising at least two airbrakes that are radially deployable so as to increase the projectile's aerodynamic drag,
- wherein each airbrake is a flap pivoting around a pivot integral with said projectile and parallel to its axis, and each said flap has an external profile covering the arc of a circle whole diameter is substantially equal to that of an external part of said projectile and an indent intended to allow said flap to fold around an axial support integral with said projectile.
