An arrow-type warhead comprises an envelope, a filling, a hardened head section to promote penetration of the target and a stabilizing mechanism to stabilize the warhead in flight, hi some embodiments the filling is pyrophoric and undergoes an exothermic reaction with the envelope upon impact. In other embodiments the filling is incendiary and undergoes reaction with the envelope upon impact in an oxygen rich-environment. In yet other embodiments, the filling is explosive. In all embodiments, the warhead may be equipped with a mini-rocket propulsion mechanism for propelling the warhead to the target.

A multi-caliber fuze kit includes a fuze housing configured for coupling with multiple projectiles. One or more canards are moveably coupled with the fuze housing. The one or more canards are adjustable between two or more canard configurations. In a first canard configuration, the one or more canards are at a first canard angle relative to a bore sight of the fuze housing, and the first canard angle is configured for use with a first projectile. In a second canard configuration, the one or more canards are at a second canard angle relative to the bore sight of the fuze housing, and the second canard angle is configured for use with a second projectile. The first and second canard angles are different. In another example, in the first canard configuration the one or more canards include a first canard shape configured to provide a first specified trajectory with the first projectile. In the second canard configuration the one or more canards include a second canard shape configured to provide a second specified trajectory with the second projectile. The first canard shape and the second canard shape are different.

An arrow-type warhead (100,200,300,400,500,600,700) comprises an envelope (102,202), a filling (108), a hardened head section (104) to promote penetration of the target and a stabilizing mechanism (106,210,302,402,502,602) to stabilize the warhead in flight, hi some embodiments the filling (108) is pyrophoric and undergoes an exothermic reaction with the envelope upon impact. In other embodiments the filling is incendiary and undergoes reaction with the envelope upon impact in an oxygen rich-environment. In yet other embodiments, the filling is explosive. In all embodiments, the warhead may be equipped with a mini-rocket propulsion mechanism (802) for propelling the warhead to the target.

Ammunition cartridge (1) comprising a rigid casing (4) including a tubular sleeve (16)and a base (14) closing an end of the casing, a projectile (6) mounted at another end of the casing, a propellant charge (10) contained inside the casing, and an ignition device (8). The ignition device comprises an ignition charge (56) arranged to ignite the propellant charge at a point of ignition distal from the base (14) and proximal the projectile (6).
摘要:
A guiding assembly is adapted to be connected to a projectile and comprising a rear main unit adapted to be connected to the front end of the projectile, and a front main unit rotatably connected at its rear end to the front end of the rear main unit. The front main unit is adapted to rotate about a central longitudinal axis. A relative speed control unit is operable between the rear main unit and the front main unit and capable of providing spin braking force to slow the relative speed of rotation of the front main unit. An at least one guiding fin radially extends from the front main unit. The pitch angle of the fin is controllable by a return spring connected to the fin so that the pitch angle of the fin is growing as the aerodynamic pressure on the fin lowers and it is growing smaller as the aerodynamic pressure on the fin gets bigger.
摘要:
A low-heat- transfer coupling or assembly is configured to mechanically couple together a pair of mating parts (12, 14), one of which may be in a heat-producing environment. By roughening at least part of the surface (36, 46) of one of the parts (12), the contact area between the mating parts can be reduced, while still maintaining the structural integrity of the connection. The roughening can be a knurling process of all or part of the mating surface on one of the parts. This can produce a series of recesses on the surface that are in contact with the other part. The recesses can be small enough, interspersed with non- etched areas of the contact surface, that structural integrity of the coupling between the parts is still maintained. The coupling may be between a leading edge of an aircraft control surface, such as a missile fin (200), and a body of the control surface.

摘要:
Изобретение относится к боеприпасам огнестрельного оружия, как к гладким, так и к нарезным стволам. Калиберный снаряд с жестким креплением к корпусу стабилизирующего оперения, пластины которого имеют продолжение на корпус, центрируя снаряд по стволу. В предложенном варианте на трение и нагрев уходит около 1% энергии выстрела, к тому же вибрации минимальны. Остальная энергия уходит по назначению, а это весьма не мало. Стирание ствола практически нет. Применение снаряда в гладкоствольных и нарезных стволах на много увеличивает срок службы самих стволов. Применение оперенных снарядов позволяет увеличить начальную скорость, а в варианте со втулкой-соплом в которой инициируется действие второго заряда после основного, позволяет еще значительно увеличить скорость снаряда. А так же за счет аэродинамического и гироскопического эффектов повысить убойное действие на дальних расстояниях за счет большей сохраненной энергии, улучшить кучность боя и настильность траектории.
