Definitions

  • the invention relates to a method and a device for transmitting information on programmable floors, with at least one the time of dismantling the dismantling time determining the projectile is transferred.
  • European patent applications EP 0 802 390, EP 0 802 391 and EP 0 802 392 have disclosed a method and a device for calculating the disassembly time of a programmable projectile, by means of which the probability of such projectiles being hit can be improved.
  • the calculation is based on at least one target distance to a target object determined from sensor data, a projectile speed measured at the muzzle of a gun barrel and a predetermined optimal disassembly distance between a target meeting point and a projectile disassembly point.
  • the given optimal disassembly distance is kept constant by correcting the disassembly time of the projectile.
  • the correction is made by adding a correction factor multiplied by a speed difference to the disassembly time.
  • the projectile speed difference is formed from the difference between the current measured projectile speed and a lead speed of the projectile, the lead speed being calculated from the mean of a number of previous, successive projectile speeds.
  • the disassembly time at the mouth of the gun barrel becomes inductive transferred to the missile flying past when it was shot, for example with magnetic bullets of larger calibers lead to transmission difficulties can.
  • the invention has for its object to propose a method of the type mentioned, that does not have the disadvantages mentioned above.
  • the disassembly time is transmitted in the area of the conveyance path of the projectiles between a magazine of a gun and the start of the flight path of the projectiles, the disassembly time being corrected by means of a dead time dependent on the selected transmission point.
  • apart from the disassembly time at least transmit the correction factor.
  • the information at the cartridge chamber or in front of the gun transferred.
  • FIG. 1, 1 denotes a fire control system, which consists of a search sensor 3 for the detection of a target 4 , a follow-up sensor 5 connected to the search sensor 3 for target detection, 3-D target tracking and 3-D target measurement, and there is a fire control computer 6 .
  • the fire control computer 6 has at least one main filter 7 and a lead computing unit 9 .
  • the main filter 7 is connected on the input side to the follow sensor 5 and on the output side to the lead computing unit 9 , the main filter 7 receiving the 3-D target data received from the follow sensor 5 in the form of estimated target data Z such as position, speed, acceleration, etc.
  • Computing unit 9 forwards. Meteorological data Me and a current measured projectile speed Vm can be fed to the lead computing unit 9 via further inputs.
  • the projectile 18 is a programmable projectile with primary and secondary ballistics, which is equipped with an ejection charge and a time fuse and is filled with sub-projectiles 19 .
  • a correction arithmetic unit 12 is connected on the input side to the lead arithmetic unit 9 and on the output side to an update arithmetic unit 11 , which is also connected on the input side to the lead arithmetic unit 9 .
  • a dead time adaptation 40 is connected on the input side to the update computing unit 11 and on the output side to a transmission device 41 which is connected on the input side to the correction computing unit 12 .
  • the transmission device 41 works inductively or also galvanically or optronically and can be arranged at any point on the conveying path of the projectiles 18 between a magazine of a gun and the beginning of the flight path of the projectiles, the cartridge chamber of the gun being preferred.
  • Reference numeral 42 designates a further arithmetic unit which, based on a given partial ballistic function f (t, Vo_typ, Me, Elevation), a current meteo (Me) and measurement information, calculates projectile data if this is necessary for an autonomous projectile measurement.
  • the update computing unit 11 is omitted, since its function is carried out by the correction computing unit 12 .
  • the correction computing unit 12 is assigned to the fire control 1 .
  • the lead computation unit 9 calculates a hit time Tf from a lead rate VOv and the target data Z, taking meteorological data Me into account ( FIGS . 1 and 2 ).
  • the lead computing unit 9 also determines gun angles a and l.
  • the quantities Tf, VOv, a and l are fed to the correction computing unit 12 , in which a correction factor K is calculated according to an equation known from the documents mentioned at the beginning.
  • the lead speed VOv, the correction factor K, the hit time Tf and a split distance Dz corresponding to the distance between the split point Pz and a hit point Pf are entered into the update computing unit 11 and a corrected split time according to an equation known from the aforementioned documents Tz (Vo_typ) calculated.
  • the decomposition distance Dz is supplied to the correction arithmetic unit 12, in which both the correction factor K and the corrected decomposition time Tz (Vo_typ) are calculated.
  • the decomposition distance Dz is input into the lead computing unit 9 , so that the latter outputs the decomposition time Tz to the correction computing unit 12 instead of the meeting time Tf.
  • the update speed computing unit 11 is supplied with the lead speed VOv, the disassembly time Tz and the correction factor K, the corrected disassembly time Tz (Vo_typ) being calculated.
  • the corrected disassembly time Tz (Vo_typ) calculated according to FIGS. 1, 2 and 3 is corrected for the dead time adaptation 40 , in which it is corrected by means of a dead time which is dependent on the position of the transmission device 41 .
  • the dismantling time Tz (Vo_typ) and the correction factor K which are adapted in this way are fed to the transmission device 41 and transmitted to the programmable projectile 18 , the projectile 18 receiving with the correction factor K additional information about the relative target / projectile geometry. It is also possible to adapt the correction factor K using the dead time adjustment 40 (dashed lines FIGS . 1 to 3 ).
