A system for quick arming of a detonation or excitation assembly, wherein the system comprises a first barrier means which, as long as it has not been removed, prevents full activation of an initiation chain of the assembly, and whose removal is dependent on receiving indication from at least one first sensor, and then its removal is reversible in a manner that it will return and once again prevent full activation of an initiation chain, and a second barrier means which also prevents full activation of the initiation chain as long as it has not been removed, and whose removal is dependent on receiving indication from at least one second sensor, and this—following after receiving indication from the first sensor, and removal of the second sensor is irreversible in a manner that leaves the initiation chain executable, and wherein the first and second sensors are independent of one another, and as long as no indication has been received from the second sensor, the first barrier means is returnable to its place in a manner that will return and once again prevent full activation of the initiation chain, and an active protection system utilizing a plurality of those quick arming system for activation of the protection system's interceptors while implementing a method for quick and selective arming of the active protection system's detonation or excitation assemblies.
摘要:
A shutter mechanism for covering a wing's spreading opening formed in an airborne body and a method for covering such opening while implementing the shutter mechanism, wherein the shutter comprises at least one flap assembly, and wherein from the instant that a deployed wing of the airborne body passed and moved over it, it is biased by traction of at least one springy element to an angular motion around an axis, unto a condition where the flap component of the assembly is positioned so that it is substantially conformal to the outline of the outer surface of the fuselage of the airborne body and while it covers the opening through which the wing passed in its motion; and from an instant that the wing returned and connected to the flap component of the assembly, the flap is biased to an angular motion counter the spring, to the state that the wing returns and is relocated on its top surface.

An explosive system and corresponding method employ a number of explosive portions, each of sub-critical dimensions so that initiation of the portion would result in incomplete detonation. A selectively-deployable spacer arrangement or deployment mechanism is deployed between a storage state in which gaps or misalignments are maintained between the explosive portions so that the explosive system remains undetonatable, and a detonable state in which the portions are brought together sufficiently to function as a combined explosive charge having effective dimensions larger than critical dimensions, rendering the explosive system detonatable.

Belt/Metallic Link Chain Loaded Ammunition Feeder in a Remote Controlled Weapon Station (RCWS). The feeder includes a feeding mechanism for routing chained ammunition from ammunition reservoir means towards the weapon's bullets entrance opening. The feeding mechanism has a first chute assembly for routing chained ammunition from the ammunition reservoir means towards the region of the RCWS's elevating/lowering axis, and a second chute assembly for continuing routing the chained ammunition from the region of the elevating/lowering axis towards the entry opening of the bullets entrance of the weapon. The chained ammunition traverses over the elevating/lowering axis region by passing from the first chute assembly to the second chute assembly. The first chute assembly remains static and the second chute assembly is dynamic and propelled together with the mounting bracket assembly around the elevating/lowering axis.
摘要:
The present invention relates to warheads with blast wave conditioners and in particular to devices for quickly removing a door to permit entry through the doorway. It discloses a device and method of shaping the pressure wave pattern by the use of inert material. The inert material of the present invention is used to reduce localized directional effects occurring at the point of impact, instead generating a more diffuse pressure-wave pattern across the target surface.

The invention relates to an optical system for the detection of a flying or moving object approaching a target, which compriseŝ (a) one or more transmitter-receiver sets positioned at an external surface of a wall of said target, each of said transmitter-receiver sets comprising: (a.1) a light transmitter for creating a fan-like planar or curved optical curtain in front of said wall of the target; (a.2) a receiver which comprises a two-dimensional focal plane array, said focal plane array being spaced apart from said transmitter and being positioned at a plane not parallel to said optical curtain such that a field of view of said focal plane array covers at least a portion of the entire area of said optical curtain; and (b) one or more processing units for determining at least a location of intrusion of said flying object to within said optical curtain by means of determining pixels within said focal plane array that are affected by reflections or scatter due to said intrusion of said flying object.
摘要:
The invention is a method and apparatus for creating mode division multiplexed channels capable of integration into photonic integrated circuits with direct spatial separation at the receiver end, thus removing the need for a DMUX module or at least significantly simplifying it. This is achieved by using a set of actuators that induce controllable mode mixing in a multi-mode fiber (MMF) at the transmitter in such a way that spatially separated channels are achieved at the receiver. As a result, no DMUX is required and failure of a single channel does not cause total communication link failure as occurs in links implemented with MUX/DMUX.
