A spin-stabilized artillery projectile (11) can be easily subsequently fitted with an axially symmetrical aerodynamic braking device for reducing the ballistic trajectory if the tip (14) which is equipped with the fuse (13) and which is easily removable from the projectile body (12) is equipped at approximately half its height with flap-shaped sectors (24) which are pivotably mounted in such a way that they can be pivotably extended and which in their launch position fit snugly into the conical peripheral surface of the tip (14) and in the operative position are pivotably extended to form a radial ring which is closed or which has gaps.
A spin-stabilised projectile (11) having an aerodynamic braking device in the front region of the projectile, which along its trajectory can be radially extended from a launch position into the axially symmetrical operative position, characterised in that its tip (14) is provided approximately in its central transverse cross-sectional plane with mounting locations for flap-shaped sectors (24) of an annular disc which can be pivoted from a launch position in the peripheral surface region of the tip (14) into an operative position approximately transversely with respect to the longitudinal axis (28) of the projectile.
A projectile according to one of the preceding claims characterised in that the sectors (24) are suspended around the pins (25) with leg bending springs which are supported radially with respect to the sectors (24) against the fuse casing (27).
A projectile according to one of the preceding claims characterised in that the width of the sectors (24) which overlap each other in their launch position produces in the operative position thereof a ring which has gaps formed by openings therein, substantially transversely with respect to the longitudinal axis (28) of the projectile.
A projectile according to the preceding claim characterised in that the gaps (32) are spanned across by flexible bridging means (33) stretched between mutually peripherally adjacent sectors (24).
A projectile according to the preceding claim characterised in that the sectors (24) are narrow spokes.
A projectile according to the preceding claim characterised in that the spring plates (34) are fixed to a sector (24) on both sides thereof in mutually displaced relationship in the axial direction of the projectile.
