The present invention relates to a method and a shell (1) for achieving variable firing range and effect when firing from a launcher, which shell (1) contains a firing charge (10), a rocket motor charge (6) with gas outlet (8), a rocket motor nozzle (9) and an active part (5). According to the inven
The present invention relates to a method and a shell (1) for achieving variable firing range and effect when firing from a launcher, which shell (1) contains a firing charge (10), a rocket motor charge (6) with gas outlet (8), a rocket motor nozzle (9) and an active part (5). According to the invention, this is achieved by virtue of the fact that the shell (1) also contains a release mechanism (15) for releasing the rocket motor nozzle (9) from the rocket motor charge (6) after a time delay determined with regard to firing range and effect, and that the rocket motor charge (6) comprises a propellant which is detonable.

Method whereby variable firing range and effect at the target is achieved with a shell fired from an automatic motor-driven gun with an automated ammunition handling system, which shell contains a firing charge whereby the shell is fired from the launcher, a rocket motor comprising a rocket motor
1. Method whereby variable firing range and effect at the target is achieved with a shell fired from an automatic motor-driven gun with an automated ammunition handling system, which shell contains a firing charge whereby the shell is fired from the launcher, a rocket motor comprising a rocket motor charge with a gas outlet and a rocket motor nozzle whereby the shell is propelled in a trajectory towards a target, andan active part which takes effect at the target, in which the firing charge is initiated by a first initiating device and in which the active part is initiated by a second initiating device, which second initiating device is activated by a programmable activating device,wherein the rocket motor charge contains a detonable propellant, which propellant is detonated in response to initiation of the active part, and in that the shell also contains a release mechanism, which releases the rocket motor nozzle or part of the rocket motor nozzle from the rocket motor, and in that the release mechanism is activated by the programmable activating device after a time delay determined with regard to firing range and effect. 2. Method according to claim 1, wherein the firing charge of the shell is arranged in the rocket motor nozzle of the shell to facilitate handling of the shell in the automated ammunition handling system, since the otherwise occurring handling of cases for firing charges is no longer required. 3. Method according to claim 1, wherein the rocket motor charge of the shell is initiated by the firing charge via the gas outlet of the rocket motor charge. 4. Method according to claim 3, wherein the firing charge of the shell is arranged in the rocket motor nozzle of the shell to facilitate handling of the shell in an automated ammunition handling system, since the otherwise occurring handling of cases for firing charges is no longer required. 5. Method according to claim 3, wherein component parts of the shell are produced in combustible material to facilitate handling of the shell. 6. Method according to claim 5, wherein the rocket motor charge of the shell is arranged such that it is initiated by the firing charge via the gas outlet of the rocket motor charge. 7. Method according to claim 3, wherein the component parts of the shell are the percussion cap and the container of the rocket motor. 8. Shell for achieving a variable firing range and effect when fired from a launcher, which shell contains a firing charge for firing the shell from an automatic motor-driven gun with an automated ammunition handling system, a rocket motor comprising a rocket motor charge with a gas outlet and a rocket motor nozzle for propelling the shell in a trajectory towards a target, an active part for effect in the target,a first initiating device for initiating the firing charge,a second initiating device for initiating the active part, anda programmable activating device for activating the second initiating device wherein the rocket motor charge comprises a detonable propellant, and in that the shell also contains a release mechanism for releasing the rocket motor nozzle or part of the rocket motor nozzle from the rocket motor, which release mechanism is optionally activable by the programmable activating device after a time delay which is determinable with regard to firing range and effect at the target. 9. Shell according to claim 8, wherein component parts of the shell are produced in combustible material to facilitate handling of the shell. 10. Shell according to claim 8, wherein the component parts of the shell are the percussion cap and the container of the rocket motor.
