    Abstract: A projectile for the dispersal of a load with time delay after firing from a launching tube (1) with hot gas under pressure is described. It comprises a cylindrical casing (2) comprising a cross wall (3) on one side of which there is a first pressure chamber (7) limited outwardly by an external side wall (4), provided with a supply opening (5) for the hot gas. The cross wall (3) limits on its other side a second pressure chamber (9) which is formed by the casing and a piston (8) axially movable in the casing, which stands in connection with said load (10). A throttled gas connection (11)is provided between the first and second pressure chambers (7, 9). The piston (8), under the effect of a pressure built up in the second pressure chamber, is arranged to perform an axial movement, firing the load (10) out of the casing (2), but not until the pressure has reached a predetermined level. The projectile is characterized particularly in that a fibrous material (16) with relatively good thermal conductivity, for instance steel wool, is so arranged in the first pressure chamber (7), that the pressure in the gas conducted to the first pressure chamber remains relatively constant with time, whereby the pressure in the gas conducted to the second pressure chamber (9) shows a relatively constant increase per time unit.
