Abstract
A smoke-generating projectile has a decomposable effective mass, the mass including a quick-burning deception component for generating spontaneous smoke, and a slow-burning concealment component for generating persistent smoke. The projectile includes an igniter, an ejection charge and/or ignition decomposition charge and at least one ignition delay device. The projectile is constructed so that the energy of decomposition of at least one of the effective mass components is constrained in a radial direction. The ejection charge and/or the ignition decomposition charge, as well as at least one ignition delay device, is installed in the effective mass.

In a projectile comprising a decomposable effective mass, an igniter, a decomposition charge, and an ignition delay device, the improvement wherein the effective mass is disposed within a container, and the charge is arranged within the effective mass for producing decomposition thereof, the container comprising longitudinally spaced end walls and a side wall, the end walls being interconnected by a connection separate from the side wall which keeps the end walls interconnected during decomposition of the effective mass, whereby the energy of decomposition is constrained to occur in a lateral direction.
A method of deploying a smoke-generating projectile comprising the steps of:
- A) providing a unit comprised of first and second substantially cylindrical containers secured together, a smoke-generating effective mass including a deception component disposed in the first container, and a concealment component disposed in the second container;
- B) igniting an injection charge disposed in the unit to launch the unit;
- C) causing the deception component to be ignited to destroy all-at-once a side wall encasing the deception component, while the energy of decomposition is constrained in a radial direction to produce spontaneous smoke following a first time delay;
- and thereafter
- D) causing the concealment component to be ignited and produce persistent smoke after a further time delay, and while the first and second containers remain secured together.
A projectile comprising an igniter, an ignition delay device, separate containers carrying respective decomposable effective masses to be ignited at separate times following a launching of the projectile, a decomposition charge arranged to produce decomposition of an initial one of the masses that is the first of the masses to be ignited, the container which carries the initial mass including longitudinally spaced end walls and a side wall, the end walls being interconnected by a connector separate from the side wall for keeping the end walls interconnected during decomposition of the initial mass, wherein the side wall is rupturable in response to the decomposition of the initial mass while the end walls remain interconnected to constrain the discharge of energy generated by the decomposition of the initial mass to a lateral direction.
