Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to of the invention
Specific embodiment is described in further detail.
The invention proposes a kind of burst-firing hit rate test methods, for specific objective and operational distance, specific
Correlation between respectively sending out in the case of the shooting of group number and specific hair number, when considering due to burst-firing causes every transmitting bullet initial
Disturbance is different, obtains hit probability using single shot hit rate and running fire correlation results, includes the following steps：
Step 1: the determination of target target size and shooting distance
It is effectively to destroy that the robot weapon platform for installing 30mm chain type automatic gun, which is directed to the combat mission task of ground target,
Oppose Tank and Armoured Vehicle, compacting is eliminated and opposes simple firepower launch point and effective strength.When the Operation Target of 30mm chain type automatic gun
When for enemy combatant and common fighting machine, usually choosing 30mm frag-demolition shell is selection of shells object, at 4000 meters
In maximum range, take it is quiet to quiet, quiet to dynamic two kinds of fire control shooting modes, penetrated with short burst-firing mode by single-point to enemy
Effective strength is shot at；When Operation Target is lightweight armor target and fixed fortification, usually choosing 30mm armor-piercing bullet is bullet
Kind of selecting object, in 2500 meters of maximum ranges, take it is quiet to quiet, quiet to dynamic two kinds of fire control shooting modes, mainly take single-shot
Fixed fire shooting mode is shot at unfriendly target.Meanwhile to burst-firing closeness in robot weapon platform war skill index
It is required that being：
30mm sandy debris flow (200m running fire)≤0.47mil × 0.77mil；
30mm armor-piercing bullet (200m running fire)≤0.46mil × 0.64mil；
Therefore, the regulation of the analysis of comprehensive weapon station combat duty and skill index of fighting, determines penetrating for running fire hit rate test
Hitting distance is 200 meters.
In 200 meters of shooting distances, target plate size is sufficiently large, usually should be not less than height and lateral dispersion median error
8 times, it is ensured that the point of impact of normal projectile is all fallen on target comprehensively.Accordingly, it is determined that the mesh of 200 meters of burst-firing hit rates test
Target is having a size of 4.6m × 2.3m, and there is the black cross hairs for aiming at target surface center, and cross hairs wire length is 1 meter, can also prolong
The edge of target is grown to, line width can be 5~10cm, as shown in Figure 1.
Step 2: the determination of experimental group number and every group of hair number
On the one hand, often there are systematic error and random errors during actual transmission for weapon system, it is meant that its
Fire accuracy can only be a statistic, i.e., individual is upper different, but has statistical property again in certain amount, in other words,
Experimental group number calculates its fire accuracy when needing to reach certain amount just have statistical property；On the other hand, it is found by emulation, it is distant
Weapon platform is controlled when carrying out the shooting of different running fire numbers, weapon system vibration characteristics, fire accuracy can change, i.e., different
Running fire number may result in different firing densities.Therefore, this step is by dynamics simulation, the mesh determined based on step 1
Target size and shooting distance emulate fire accuracy under robot weapon platform difference running fire number, determine different running fire numbers
Corresponding fire accuracy and experimental group number.
Carry out the Launch Dynamics emulation of 3 running fires, 5 running fires and 10 running fires, fire accuracy respectively to robot weapon platform
With the change curve of emulation group number as shown in Fig. 2~Fig. 4, table 1.
The different running fire number robot weapon platform vertical target dispersions of table 1 and a stable group number
From simulation result, on the one hand, robot weapon platform fire accuracy is different under different running fire numbers, wherein 3 connect
Under hair, 5 running fires, 10 running fires robot weapon platform vertical target dispersion be respectively 0.827mil × 0.745mil, 1.03mil ×
0.86mil, 1.715mil × 1.263mil show that fire accuracy is deteriorated with the increase of running fire number；On the other hand, different to connect
The emulation group number for sending out lower robot weapon platform fire accuracy several and reaching stationary value is different, wherein 3 running fires, 5 running fires, 10 running fires pair
The group number of stablizing answered is respectively 14,8,15, shows that stablizing group number does not form monotonicity with the increase of running fire number.For with bullet
Amount, projectile sum needed for 3 running fires, 5 running fires, 10 burst-firings reach fire accuracy stationary value be respectively 42 hairs, 40 hair, 100 hair,
Therefore, based on the considerations of saving bullet number, bullet number needed for robot weapon platform reaches fire accuracy stationary value under 5 running fires is most
It is few.
Step 3: running fire hit rate calculation method
This step is based on step 2 as a result, weapon system single-shot, running fire hit rate is calculated by Shape Coefficient method.
It is tested first by single shot and obtains projectile height to dispersion probability error GgWith horizontal direction dispersion probability error Gf, then by Φ
(β) function method calculates the hit probability P on heightgWith the hit probability P in horizontal directionf, finally obtained with probability multiplication formule：
In formula, P be single shot when hit probability, x1、x2、y1、y2Respectively rectangular target target is left and right, upper and lower
Edge coordinate value, wherein center of gravity of the coordinate center in rectangle, McFor the Shape Coefficient of target, the Shape Coefficient of typical target such as table
Shown in 2.
The Shape Coefficient of 2 typical target of table
The above-mentioned single-shot hit rate calculation method based on Shape Coefficient method is used for reference, it is corresponding in conjunction with running fire numbers different in step 2
Wherein single-shot dispersion probable error is replaced with the running fire after stablizing by different fire accuracies and the simulation result for stablizing group number
Dispersion probable error obtains running fire hit rate：
In formula, PmFor burst-firing hit rate, Ggm、GfmProjectile height after respectively stable is to dispersion probability error and water
It puts down to dispersion probability error, Pgm、PfmRespectively Ggm、GfmIt substitutes into Φ (β) function and calculates corresponding height to, horizontal direction hit
Probability.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
