Definitions

  • a projectile contains an explosive charge and a fuse assembly which carries axially spaced groups of angularly spaced bundles of chaff and axially spaced explosive charges. Each bundle has an explosive charge.
  • the explosive charge in the projectile is detonated so that the fuse assembly and the bundles of chaff are ejected. The fuse is ignited by the detonation.
  • the groups are ejected progressively from the fuse assembly, by detonation of the charges in the fuse assembly, the bundles of each group being blasted laterally from the fuse assembly, by the respective explosive charge.
  • Each bundle is disintegrated after a predetermined time interval by its own explosive charge. All the charges and the fuse are set to detonate at predetermined time intervals so that the resultant cloud has a specific shape.
  • apparatus for forming a cloud of radar reflecting chaff comprising bundles of radar reflecting chaff and ejector means for ejecting the bundles from a projectile in flight, each bundle being arranged to disintegrate at the end of a predetermined time interval after ejection from the projectile so that, once all the bundles have been disintegrated the chaff is scattered within the atmosphere to form a cloud of a substantially predetermined form.
  • the ejector means may be arranged to eject groups of bundles of chaff laterally with respect to the flight path of the projectile at spaced intervals along the flight path so as to form a substantially spherical cloud.
  • the ejector means may be arranged'to eject each bundle of each group laterally along a respective path which extends radially from the flight path in a different direction to the paths of the other bundles of the group.
  • the ejector means may include an explosive charge, the arrangement being such that bundles of chaff are ejected from the projectile by explosion of the explosive charge.
  • the ejector means includes a number of explosive charges, the arrangement being such that each group of bundles is ejected by explosion of a respective explosive charge.
  • Each bundle may include a further explosive charge and is arranged to be disintegrated by detonation of the further explosive charge.
  • each bundle may include a fuse which is arranged to be detonated by explosion of the respective explosive charge which is arranged to eject the bundle laterally with respect to the flight path, each fuse determining the time interval betwen lateral ejection and disintegration of the respective bundle.
  • the ejector means may comprise a tubular assembly, that part of each bundle which includes said fuse being spigotted into a radial aperture through the tubular wall of the tubular assembly, the respective explosive charge being housed within the portion of the bore of the tubular assembly with which the radial aperture communicates.
  • Each bore portion which houses an explosive charge may be spaced from the juxtaposed bore portion or portions which also house an explosive charge by a bore portion of reduced diameter which delays ignition of the explosive charge which is further from the initially ignited explosive charge.
  • the tubular assembly comprises a number of tubular elements screwed together end to end.
  • Each tubular element may comprise a bore portion which houses an explosive charge and a juxtaposed bore portion of reduced diameter.
  • the tubular assembly may include an end tubular element which defines a said bore portion of reduced diameter which serves to delay ignition of the initially ignited explosive charge.
  • the spigot part of each bundle is tubular and said fuse is housed within the bore thereof.
  • a bundle of radar reflecting chaff for use in apparatus according to the preceding aspect, comprising chaff packed within a peripheral band and carrying a fuse which is adapted to be ignited by ejection of the bundle from a projectile in flight, the fuse being arranged so that the bundle disintegrates when the fuse has burnt through at the end of a predetermined period of time.
  • the fuse may be arranged to burn through the peripheral band so that the bundle disintegrates, or to ignite an explosive charge in the bundle, the bundle being disintegrated by explosion of the explosive charge.
  • the fuse may be housed within the bore of a tubular spigot which projects outwardly from the peripheral band.
  • bundles of radar reflecting chaff are ejected from a projectile in flight and, at the end of a respective predetermined time interval, each bundle of chaff is disintegrated and the chaff scattered within the atmosphere so that, once all the bundles have been disintegrated and the chaff scattered, the scattered chaff forms a cloud of a substantially predetermined form.
  • each bundle of each group is ejected laterally along a respective path which extends radially from the flight path in a different direction to the paths of the other bundles of the group.
  • Bundles of chaff may be ejected from the projectile by the detonation of an explosive charge. Where groups of bundles are ejected laterally at spaced intervals along the flight path, each group may be ejected by the detonation of a respective explosive charge. Each bundle may be disintegrated by detonation of a further explosive charge. Conveniently the further explosive charge may be detonated by a fuse which was ignited by explosion of the respective explosive charge which ejected the bundle laterally with respect to the flight path, each fuse determining the predetermined time interval between lateral ejection and disintegration of the respective bundle.
