Abstract
A method of, and apparatus for, adjusting a projectile fuze after firing the projectile out of a weapon, wherein information is transmitted inductively from a transmitter mounted at the weapon to a receiver located in the projectile fuze. The passage of the projectile through a first element triggers the transmission of pertinent information and after such passage the information is computed and stored. Upon passage of the projectile through a second element the information is transmitted in the form of pulses to the receiver and the frequency of the pulses is coordinated to the time available during passage of the projectile so that all information can be transmitted within this time.

A method for adjusting a projectile fuze after having been fired out of a weapon barrel, wherein the information is inductively transmitted in the form of pulses from a transmitter secured to the weapon to a receiver located in the projectile fuze, and the frequency of the pulses is tuned to the time available during passage of the projectile at the transmitter, so that all information can be transmitted within this time, the improvement comprising the steps of:
- 1. passing the projectile through a first element;
- 2. initiating the transmission of information upon passage of the projectile through the first element;
- 3. after such passage first calculating the information and storing the same;
- 4. passing the projectile through a second element;
- and
- 5. upon passage of the projectile through the second element transmitting the information in the form of pulses to the receiver.
An apparatus for adjusting a projectile fuze after firing of the projectile through a firing weapon barrel, comprising a receiver arranged in the projectile, a transmitter secured to the firing weapon barrel, said transmitter possessing a trigger coil forming a first element, said trigger coil being arranged at a muzzle of the firing weapon barrel, a computer in circuit with said trigger coil for calculating the information, a register in which there is stored the information which is further transmitted to the fuze, the transmitter further including an induction coil forming a second element which is arranged in front of the trigger coil at the muzzle of the firing weapon barrel and which inductively transmits the information stored in the register to said receiver arranged in the projectile.
