A sub-caliber projectile of the kinetic energy type comprising a perforating rod surrounded by a sabot made of light material and allowing the projectile to be fired from a weapon, the rod being extended by a stabilizing tail. The tail is connected to the rod by a connection means that can be broken, the breaking being initiated by a control means integral with the projectile. The control means comprises a timing module which is connected to a programming interface and which is programmed before firing or during firing so as to ensure the breaking of the connection means at a reference distance relative to a target which is to be neutralized. The invention also relates to a method of neutralizing a target using such a sub-caliber projectile.

A projectile with selectable angle of attack for increased impact on a target includes an active charge and controllable initiation device for initiation of the active charge, wherein the projectile also includes at least one side-acting impulse motor for tilting the projectile relative to its trajectory from a substantially vertical position, in which the front face of the projectile is directed toward the target, into a more horizontal position, in which the outer surface of the projectile is directed toward the target.

A wing includes: a main structural member; a leading-edge member formed of material with a coefficient of linear thermal expansion different from that of material of the main structural member; an eccentric bushing that has a circular through-hole and is shaped in a cylindrical shape; and a coupling member. The leading-edge member has a first hole prolonged in a specific direction. The main structural member has a second hole. The center axis of the eccentric bushing and the center axis of the through-hole are parallel to and offset from each other. The eccentric bushing is inserted to the first hole. The first coupling member is inserted to the through-hole and the second hole to couple the main structural member and the leading-edge member.

Apparatuses for a projectile are provided, the projectile configured for weapons band launching, examples of the apparatus comprising a body, an inflation system and external walls. The body is inflatable by the inflation system, from a deflated configuration having a first volume to an inflated configuration having a second volume, greater than the first volume. The external walls are deployable from an undeployed configuration to a deployed configuration responsive to the body being inflated. In the undeployed configuration and at an operating airspeed, the center of pressure is located at a first position with respect to the projectile. In the deployed configuration the external walls provide a deployed external surface geometry exposed to an airflow corresponding to the operating airspeed, such that the center of pressure is located at a second position with respect to the projectile, different from the first position.

Nosecone and tailfin designs for aerodynamic systems are disclosed. The designs increase the usable volume within the fuselage of the aerodynamic system while still maintaining the same length for the aerodynamic system. In an example, the nosecone is truncated and includes a blunted tip compared to standard nosecone designs, which allows for more useable space along the length of the aerodynamic system. A tailfin structure is fabricated as a separate piece (separate from the fuselage of the aerodynamic system) and slips over a portion of one end of the fuselage, thus allowing useable volume within the fuselage beneath the tailfin structure. The tailfin structure also includes a hollow cavity for holding componentry (e.g., an RF transmitter, receiver, or transceiver device) with wires that feed through the tailfin structure and into the fuselage of the aerodynamic system.

The invention relates to a penetrating and explosive projectile (1) provided with a trajectory-stabilizing fin assembly (8) which is secured to a body of the projectile by a mechanical connection. The fin assembly (8) includes a tapped tube (14) which engages on a threaded rear cylindrical shank (10) of a tail (9) connected to the projectile body (2), thereby forming a threaded mechanical connection (13) between the tail unit (8) and the body (2). This projectile (1) is characterized in that it includes means ensuring the fragilization of the threaded connection (13) on impact on a target, the fin assembly then separating from the projectile body.
