Definitions

the invention relates to a method for increasing the first hit probability of a ballistic weapon.
the projectile In the case of weapons in which a projectile is fired from a pipe, the projectile describes a trajectory that depends on the velocity of the projectile and the position of the pipe. Especially with long ranges and / or the use of temporary ammunition, an exact calculation of this trajectory is essential for the targeting process.
the object of the present invention to provide a method with which the first hit probability of a ballistic weapon can be increased.
the proper movement of the weapon is taken into account.
environmental conditions such as air temperature or pressure and ammunition parameters such as powder temperature or change in initial velocity are taken into account.
the powder temperature refers to the temperature of the powder before ignition and the change in the initial speed caused by manufacturing tolerances and / or wear of the pipe deviation from the nominal velocity of the projectile, which is adjustable or measurable.
the initial velocity of the projectile relative to the weapon is advantageously superimposed three-dimensionally with the weapon's own velocity.
the vector of the intrinsic speed of the weapon is preferably transformed into a coordinate system based on the tube of the weapon.
the proper motion of the weapon carrier in the calculation of Vorhalt, essay and time of flight of the projectile is thus fully or graduated in the calculation of the outgoing and outgoing ballistics considered.
the advance and / or attachment and / or time of flight of the projectile are determined iteratively from the airspeed and position of the weapon. If, for example, a lead is determined, this alters the orientation of the weapon with respect to its own velocity and thus the position of the coordinate system related to the tube of the weapon. On this basis, the lead is determined again and based on the next iteration step.
the weapon is tracked during the iterative determination, resulting in a quick positioning of the weapon. Alternatively, the iteration may be performed until it is sufficiently converged to then align the weapon with the result.
the actual initial velocity of the projectile is determined in a first step. This is done in response to one or more of nominal initial velocity, initial velocity change, and powder temperature parameters.
the nominal initial velocity is the bullet velocity indicated by the munitions manufacturer. Manufacturing tolerances lead to batch-dependent or batch-dependent fluctuations, which can be taken into account as changes in the initial velocity.
the powder temperature can be further considered. It is the temperature of the powder before ignition, ie essentially the last storage temperature.
the time of flight of the projectile is determined as a function of the initial speed or the initial speed and prevailing environmental conditions.
the prevailing environmental conditions may be, for example, the air temperature, the air pressure or the strength of the backwind or headwind.
other parameters such as the tube position and the position of the target relative to the weapon, z. B. a height difference, are taken into account.
the required lead is then with Using the Didion equation of transverse wind velocity v q , time of flight T, target distance R and initial velocity v 0 of the projectile calculated.
the lead is not determined from transverse wind tables, as hitherto, but taken into account by means of time tables, the environmental influences and / or ammunition parameters.
a weapon 6 (see FIG. 2) is mounted in a turret on the trough 5 of a tank as a system or weapon carrier.
the tank moves with a velocity vector ⁇ w .
⁇ w In a Cartesian coordinate system related to the tub 5, the X-axis in the forward direction of the tank, the Y-axis to the right and the Z-axis down.
the turret and thus the tube 6 of the weapon is rotated in the XY plane by the angle ⁇ to the X-axis.
the tube 6 has an elevation of the angle ⁇ from the XY plane.
the fire control computer 4 shown in FIG. 1 receives as input parameters, inter alia, the X, Y and Z components of the velocity vector ⁇ w . These components are subjected to a transformation before being supplied to the arithmetic unit 3. The transformation transforms the components into a Cartesian coordinate system, which is related to the tube of the weapon.
the axis X “corresponds to the tube bore axis.
a rotation about the angle ⁇ around the Z-axis is first made in the element designated by ⁇ .
the result is an intermediate coordinate system with the axes X ', Y' and Z.
the angle ⁇ can be changed by the fire control computer 4 and is therefore known this.
the arithmetic unit 3 calculates the lead and / or the essay based on the sighting line, not shown. These values are fed to the weapon and target control system 2. This aligns the weapon accordingly.
the new values for ⁇ and ⁇ initiate a new iteration step, beginning with the transformation of the coordinate system. Due to the changed position of the gun barrel results a new weapon-oriented coordinate system.
the determined in the arithmetic unit 3 flight time of the projectile is forwarded to the tempier system 1 to program malleable ammunition with a precise ignition timing.
the weapon can be aligned by the control system 2.
the inventive method is not limited to use in tanks. Rather, it is transferable to all types of weapons for land, air and water vehicles. For the procedure, only knowledge of the velocity vector ⁇ w of the weapon carrier as well as the angles ⁇ and ⁇ between the weapon and the weapon carrier is necessary.
the initial velocity of the projectile is first determined as a function of one or more of the parameters nominal initial velocity, change of the initial velocity and powder temperature. This is done by means of relevant tables or an approximate or exact calculation. From this initial velocity v 0 , the flight time of the projectile is determined in a second step. In determining the flight time, the prevailing environmental conditions, such. As air temperature, air pressure or backwind or headwind, be included. Also geometric conditions, such as the distance to the target or a height difference between weapon and target, are taken into account.
the nominal initial velocity of the projectile is 1000 m / s with a flight time of 2.5 s.
transverse wind tables are used instead of the method according to the invention, the nominal values for initial speed and flight time result in a lead of 0.1432 degrees or 2.546. At 2000 meters from the weapon, this difference leads to a deviation of 1.57 meters. A correspondingly small target would thus be missed in the determination of the attitude using crosswind tables.
the compensation of the proper movement of the weapon and the consideration of environmental conditions and ammunition parameters in the determination of advance and / or attachment can be used both separately and in combination.
