Abstract
Abstract A payload-carrying projectile 1 includes a sensor 16 and a sensor carrier 15 disposed in a launch-resistant manner in a recess 14 in the tail section 11 of the projectile 1. After impact of the projectile, which is stabilized by extendable vanes 12, in the target area, where it may penetrate the ground as necessary, the object is to deploy the sensor from its protected position inside the projectile 1and to place it as high as possible above the surface of the ground. For this purpose, the sensor 16 is connected with a concertina bellows 15 which for its part leads into a reservoir 13a which is disposed in the projectile, and which is filled with polyurethane foam mixed with a propellant gas under high pressure. The connection of the reservoir 13 with the concertina bellows 15 is made via a valve 13c which is regulated by an electronic control element 13a containing, for instance, a timer switch. After the opening of the valve 13 c the polyurethane foam 17 enters the concertina bellows 15 and expands it, thereby expelling the sensor 16 from the recess 14. Finally, the polyurethane foam 17 hardens, so that the now extended concertina bellows 15 provides a safe support for the deployed sensor 16.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
129 words
A payload-carrying projectile comprising: a projectile having a recess formed in its tail section; a payload disposed within said projectile; a sensor for the payload mounted on a sensor carrier, with said sensor and said sensor carrier being disposed, in a protected manner, in said recess during firing of said projectile with said sensor carrier comprising a concertina type bellows having one end connected to said sensor, and being disposed in said recess in a compressed state; and means for deploying said sensor from said projectile including a reservoir disposed within said projectile and containing polyurethane foam mixed with a propellant gas under high pressure with said reservoir being connected via an opening, which is closable by a valve element, with the other end of said concertina type bellows.
