  • Spreadable telescopic head for appliances, projectiles, bombs or missiles
    Patent number: 4669386
    Abstract: A telescopic warhead for a submunition ejectable from a carrier projectile the explosive charge of which is made up of submunitions scatterable and housed in the front portion of the carrier projectile, characterized in that the telescopic head includes a telescopic sliding skirt formed of a plurality of cylindrical elements, which are preferably metallic. The telescopic warhead, during storage, does not reduce the inside space requirement of the carrier projectile which leaves the inner volume available in front of the explosive charge whether the telescopic warhead is in a storage configuration or in an expanded configuration.
