Abstract

A guiding kit for guiding a projectile to a target comprises a front part and a rear part. The front part and the rear part are rotatably connected to each other to enable relative rotation about a common central longitudinal axis of rotation. The front part comprises a front transceiver (T/X) unit that is disposed next to the rear end of the front part and coinciding with the longitudinal central axis of rotation and adapted to transmit signals towards the rear part. A rear transceiver unit is disposed against the front transceiver unit and adapted to communicate with front transceiver unit when the front part and the rear part are rotating with respect to each other.

Claims (20)

1. A guiding kit for guiding a projectile to a target, comprising:

a front part; and

a rear part, wherein the front part and the rear part are rotatably connected to each other to enable relative rotation about a common central longitudinal axis of rotation,

wherein the front part comprises a transceiver (T/X) unit disposed next to a rear end of the front part, coinciding with the longitudinal central axis of rotation and adapted to transmit signals towards the rear part,

wherein a first part of an electric generator is disposed next to a front end of the rear part and comprises a generator coil, adapted to be in operational communication with a second part of the electric generator, which is disposed in the rear end of the front part and comprises magnets,

wherein the rear part comprises:

an assembly container extending from the front end of the rear part backwardly, the assembly container being adapted to receive assembly operative with the projectile, by placing the assembly inside the container with a signal receiver connectable to a receiver port; and

a receiver port disposed at the front end of the assembly container, against the transceiver (T/X) unit, facing the transceiver (T/X) unit and adapted to receive signals transmitted by the transceiver (T/X) unit,

and wherein there is complete electrical separation between the electrical units of the front part and any unit accommodated in the rear part.

2. The guiding kit of claim 1 , wherein:

the magnets of the electric generator are disposed no more than 1.5 mm from the rear end of the front part, and

the coils of the electric generator are disposed no more than 1.5 mm from the front end of the rear part and distal from the common longitudinal axis by no less than half radius of the projectile, and are adapted to cooperate with the first part of the electric generator to produce electricity when the front part and the rear part rotate with respect to each other.

3. The guiding kit of claim 1 , wherein the assembly container is adapted to accommodate an ignition and detonation control package, the package comprises:

an electronic unit, adapted to receive signals from the main control unit in the front part, and to control a safe-and-arm and electric detonator with safety mechanism and a detonation process;

a safe-and-arm safety unit, adapted to carry out safety measures under control of the electronic unit; and

a detonation booster unit, controllable by the safe-and-arm unit.

4. The guiding kit of claim 1 , wherein the assembly container is adapted to accommodate telemetry unit, the telemetry unit is adapted to receive signals from the transceiver (T/X) unit.

5. The guiding kit of claim 3 wherein electrical power to the ignition and detonation control package is provided by said generator.

6. The guiding kit of claim 3 wherein signals transferred to the ignition and detonation control package represent the status of at least one safety parameter.

7. The guiding kit of claim 1 , wherein the assembly container is adapted to accommodate a metric/telemetric unit, wherein the metric/telemetric unit is adapted to receive signals from the front part representing at least one performance parameter of the guiding kit.
