A payload-carrying projectile 1 includes a sensor 16 and a sensor carrier 15 disposed in a launch-resistant manner in a recess 14 in the tail section 11 of the projectile 1. After impact of the projectile, which is stabilized by extendable vanes 12, in the target area, where it may penetrate the ground as necessary, the object is to deploy the sensor from its protected position inside the projectile 1and to place it as high as possible above the surface of the ground. For this purpose, the sensor 16 is connected with a concertina bellows 15 which for its part leads into a reservoir 13a which is disposed in the projectile, and which is filled with polyurethane foam mixed with a propellant gas under high pressure. The connection of the reservoir 13 with the concertina bellows 15 is made via a valve 13c which is regulated by an electronic control element 13a containing, for instance, a timer switch. After the opening of the valve 13 c the polyurethane foam 17 enters the concertina bellows 15 and expands it, thereby expelling the sensor 16 from the recess 14. Finally, the polyurethane foam 17 hardens, so that the now extended concertina bellows 15 provides a safe support for the deployed sensor 16.

The target-effective mass of cartridged ammunition is increased while maintaining a predetermined cartridge length.A projectile body has a projectile tail portion extending rearwardly on which a fin or wing-stabilization arrangement is mounted. This tail portion extends rearwardly towards the immediate vicinity of the propellant charge casing bottom. A projection extends rearwardly past the wing or fin-stabilization guide arrangement. This projection includes a massive portion which separates at firing from the propellant charge casing bottom. The rear portion of the projectile body is surrounded by a sheathing of combustible material forming the ignition element which sheathing extends from the cartridge case bottom up to at least the middle of the propellant charge casing and has a longitudinal extent l.sub.2. The massive projection permits, during the combustion of the propellant charge up to separation the build up of a high gas pressure, whereby in particular a loose powder propellant charge is ignited by the ignition element for a short period of time in a uniform and reproducible manner. Thus, without increasing the length of the cartridge an increase of the target-effective mass and an increase of the projectile length is achieved with an accompanying penetration capacity increase by improving the relationship of the projectile length l.sub.1 to the projectile diameter d.sub.1.

A multi-range ammunition unit for firing at a high angle and with preselected muzzle velocities. The ammunition unit includes at least two partial propellant charges, a first one of which is fixedly mounted to the bottom of the shell casing and the second one or ones of which are fixedly mounted to the bottom of the projectile of the ammunition unit. All partial propellant charges are coaxially arranged with respect to the shell casing. Mechanical and/or electrical ignition means are provided to first ignite the first propellant charge and then selectively sequentially ignite the second propellant charge or charges.

A projectile comprising a projectile body having a rear end; and a deceleration element composed of a sheet of material at the rear end, the deceleration element having an edge region and being deployable from a folded condition to an expanded condition with the aid of rotation of the projectile, the deceleration element, when in the expanded condition, having the general form of a disk with a periphery defined by the edge region and being effective for decelerating the projectile, and wherein the deceleration element is constructed such that the edge region has a higher mass density than the remainder thereof.

A spin stabilized carrier projectile having a longitudinal axis comprising: a projectile body; and at least two submunition bodies disposed in, and ejectable from, the projectile body, the submunition bodies being spaced along the axis, each submunition body having a folded, expandable deceleration means for reducing the velocity and spin of the submunition body upon ejection from the projectile body, the deceleration means including a sheet of material for producing air resistance, and the deceleration means having different dimensions for respectively different submunition bodies so that each respective submunition body is decelerated less than the submunition body disposed behind the respective submunition body.

A bomblet has a casing and a targeting device provided with a reflector swingably secured to the casing. The reflector has a position of rest in which it is situated within a cross-sectional outline of the casing and a working position in which it is in a deployed state externally of the casing. A first guide arm is articulated to the reflector to provide for a relative pivotal motion about a first pivotal axis, and to the casing to provide for a relative pivotal motion about a second pivotal axis. A second guide arm is articulated to the reflector to provide for a relative pivotal motion about a third pivotal axis, and to the casing to provide for a relative pivotal motion about a fourth pivotal axis. All the pivotal axes are parallel to and spaced from one another and are perpendicular to the central longitudinal axis of the bomblet. The guide arms guide the reflector in a swinging motion from the position of rest into the working position. The reflector has a center of gravity located, in the position of rest, offset from the longitudinal axis in a direction of the swinging motion, whereby, upon rotary motion of the bomblet, the reflector is moved by centrifugal forces from the position of rest into the working position. Further, a locking engagement is provided for immobilizing the reflector in the working position.
摘要:
A charge formed of a mass of packed propellant is generally centered on an axis and is of radially generally uniformly and radially outwardly increasing density. This charge has a predetermined size and shape and is made by first filling particulate propellant into a chamber centered on an axis and defined by side walls extending at least generally parallel to the axis. This chamber is radially somewhat larger than the predetermined size and shape for the charge. At least some of the side walls are then displaced radially inward to reduce the volume of the chamber until the reduced chamber generally has the size and shape for the charge. The weight of the particulate propellant filled into the chamber is equal to the desired weight for the charge. The tail of a projectile is positioned in the chamber before filling the particulate propellant into the chamber. The projectile downwardly closes the chamber and can be raised after the mass is packed to push it up out of the chamber.
