Title (EN) AN ARRANGEMENT FOR LAUNCHING INTERFERENCE MATERIAL
(FR) DISPOSITIF POUR LE LANCEMENT DE MATERIAUX DE BROUILLAGE
Abstract:
(EN) A projectile (1) containing particles of interference material is fired pneumatically from a launching tube (2). Compressed air, which is supplied to the launching tube and acts on the rear face of the projectile during firing, is conducted both to a loading chamber (19) wherein the air pressure is maintained even after the projectile has left the firing tube, and also via the loading chamber to an expansion chamber (20) in which, after a specific time-lag corresponding with a certain launch height on the trajectory of the projectile, an over-pressure builds up which causes the expansion of the chamber to be initiated with simultaneous expulsion of the interference material from the projectile. The compressed air may also be conducted to the chamber (10) in the projectile wherein the interference material is accommodated, tightly packed, in order to enhance the dispersion thereof.
(FR) Un projectile (1) contenant des particules d"un materiau de brouillage est lance par voie pneumatique a partir d"un tube de lancement (2). De l"air comprime, qui alimente le tube de lancement et agit sur la face arriere du projectile lors du lancement, Est introduit a la fois dans une chambre de chargement (19) dans laquelle la pression d"air est maintenue constante, meme apres le depart du projectile, et, par l"intermediaire de la chambre de chargement, dans une chambre d"expansion (20) dans laquelle, apres un certain temps-retard correspondant a une certaine hauteur de lancement sur la trajectoire du projectile, une surpression se produit progressivement, provoquant ainsi l"expansion de la chambre et l"expulsion du materiau de brouillage. L"air comprime peut egalement etre introduit dans la chambre (10) du projectile ou est loge le materiau de brouillage, qui est tasse, afin d"augmenter sa dispersion.
