PROJECTILE FOR THE DISPERSAL OF A LOAD WITH TIME DELAY

摘要

the invention relates to a projectile that is characterized by delayed dispersal of charge after being fired from a launching tube (1) by means of a hot gas under pressure.the projectile includes a cylindrical casing (2) with a transverse wall (3) on one side of which has a first pressure chamber (7) delimited externally by a side wall (4), which has an opening (5) for the inlet hot gas.the side wall (3) defines a second chamber on the other side of pressure (9), which is formed by the casing, and a piston (8) which is axially movable within the casing and which is placed in contact with the load (10). a switch (11) to the gas system is provided between the first and second pressure chambers (7, 9).as a result of the build-up of pressure in the second pressure chamber, the piston (8) is obliged to carry out an axial movement, thus the range of the load (10) from the casing (2), provided that the pressure has reached a predetermined level.the projectile is characterised in particular in that a fibrous material (16) having a relatively high thermal conductivity, e.g., steel wool, is arranged in the first pressure chamber (7) so that the gas pressure in the first pressure chamber stay relatively constant over time.the pressure of the gas in the second pressure chamber (9) with a relatively constant and increase per unit of time.
