Shell with heat-sensitive sensor

The pressure wave from the detonated warhead (15) of a shell (14) which is launched from the object to be protected is intended to deflect an approaching kinetic-energy projectile (11) from the direction of the approach trajectory (16) by the influence of pressure on its tail control surfaces. This results in a solution for the detonation sensor system for developing the blast effect in the optimum proximity situation which is particularly simple in terms of equipment and can be achieved in a mechanically highly robust manner if the blast shell (14) is equipped with a sensor (18) whose detector element (21) is arranged behind solid optics such that it produces a field of view in the form of a hollow cone coaxially in front of it. This leads to the emission of a trigger signal when the heated nose (12) of the fast approaching kinetic-energy projectile (11) enters this response characteristic (19).
