The invention relates to the field of armament and military equipment, in particular to fire fighting machine (BM) on the purpose, for example, using a machine gun (cannon) installations.

The analysis of the literature shows that there is a way of shooting at goal artillery funds armored vehicles (tanks, infantry fighting vehicles, etc.,), lies in the detection and target recognition, target tracking and calculating the angular corrections in calculating the final device with regard to temperature and air pressure, ballistic wind-generated metasandstone, and shooting with regard to their goals /1/.

To implement this method on combat vehicles (BM) there is a firing system that includes surveillance-sight, navigation system, transmitter, stabilizer (power drive) installation, cannon (gun) installation /8/.

In the staffing tables of firing artillery weapons means armored is to be placed onboard computing systems BM, the above amendments, as a rule, the distance in the changing air pressure Hinand temperature Tinrespectively 10 mm RT.Stewie 10With as a function of range /1, 2/. The total correction rangeDis obtained as the algebraic sum of the products of corresponding sensitivityon the deviation of the i-th factorXi

,

whereD - amendment-range change of the i-th factor (if it is changed in the range respectively of ±10 mm RT.art., ±10With and so on);

n is the number of accounted variance;

Xi’ is the deviation of the i-th factor of 10% (±10 mm RT.art., ±10With and so on).

Thus, it is assumed a linear dependence of the variance vneshnepoliticheskikh parameters, such as range, from the above disturbing factors and extended in accordance with the terms of reference of the range of factors (e.g., 460 mm RT.article <H<820 mm RT.art., -50With<T<+50C).

This assumption can lead to

The closest technical solution, selected as a prototype, is a method for firing CV goal of detection and target recognition, taking on support and maintenance objectives, the determination of the kinematic corrections on the target and media, including flight time tfloorand the range of Dy, ballistic corrections: the angle of aimingand derivationdcorrections on the speed side Wzand longitudinal Wxballistic wind parallax sight cannon or machine-gun unit (PU) of mathematical expressions, constant variance, taking into account their trunks PU relative to the line of sight and target shooting /3/.

Known firing system BM on the purpose, selected as a prototype of the proposed system contains overview-sighting, a navigation system, a block of data about the external environment, actuators installation and gun or cannon installation, on-Board computing system (CS) that includes in its membership including block making aiming angleand derivationd, the inputs of which are connected to the inputs of SU is with the inputs of the actuators, and device for determination of the lead angles, and includes a processing unit lead anglesunit amendments to the ballistic wind is along the horizontal channel, the power correction for parallax along the horizontal channel, the block of formation of lead anglesunit corrections for the longitudinal wind on the vertical channel, the power correction for parallax in the vertical channel forming unit pre-empt the range of Dyunit formation flight time tfloorwhose inputs are connected via respective inputs on-Board computer system with outputs overview-sighting, navigation system, and a block of data about the external environment, as well as to the outputs of the respective blocks included in the device definition of the lead angles.

The shortcoming of the above method and implementing it systems are large systematic errors arising from the deviations metabolities factors, such as temperature and air pressure, from their normal values substantially in excess of (in accordance with TK) respectivelyTin=±10

The objective of the proposed method and implementing it systems is to increase the efficiency of fire BM by improving the accuracy due to the fact that specified amendments extended in accordance with TK ranges of temperature and air pressure.

The problem is solved in that in the known method of firing BM, consisting in the detection and recognition of targets, taking on support and maintenance objectives, the determination of the kinematic corrections on the target and media, including flight time tfloorand the range of Dy, ballistic corrections: the angle of aimingand derivationdcorrections on the speed side Wzand longitudinal Wxballistic wind parallax sight cannon or machine gun PU of mathematical expressions, constant variance, taking into account their trunks PU relative to the line of sight and shooting on goal /s temperature Tinand pressure Hinair for all ranges of firing table of amendments rangeD and choose the approximating coefficients, respectively, pressure and temperature

The problem is solved also by the fact that in the known system of fire BM on the purpose, containing OU or cannon installation, onboard computing system (CS) that includes in its membership including block making aiming angleand derivationd, the inputs of which are connected to the inputs (SU) to the outputs of the survey and sighting system, and the outputs from the inputs of the accounting unit of the Bank angle, the outputs of which are connected with the inputs of the actuators, and a device for determination of the lead angles, consisting in turn block the formation of lead anglesunit amendments to the ballistic wind is along the horizontal channel, the power correction for parallax along the horizontal channel, the block of formation of lead anglesunit corrections for the longitudinal wind on the vertical channel, the power correction for parallax in the vertical channel forming unit pre-empt the range of Dyunit formation flight time tfloorwhose inputs are connected via respective inputs on-Board the aircraft to the outputs of the survey and sighting, navigation systems and data block on the external environment, as well as to the outputs of the respective blocks included in the device definition of the lead angles, with the tion of the air, while the first and second inputs connected to the outputs of the block of data about the external environment, the third input - output processing unit pre-empt the range of Dyand its output connected to the input of block making angle of elevation and derivation.

The problem is solved also by the fact that the block of adjustments in the angle of elevation on temperature and air pressure is composed of the first and third functional converters, the first and seventh adders, the first to twelfth multiplier device, and the output of the first functional Converter connected to the inputs respectively of the third-sixth multiplier devices whose outputs are connected to first inputs respectively of the first, second, third and fourth adders, the second inputs of which are connected respectively to the outputs of the first, second, seventh and eighth multiplier device, the inputs of which as well as the input of the first functional Converter connected to the output of the shaping unit pre-empt range, the outputs of the first and second adders are connected with the first inputs respectively the ninth and tenth multiplier devices, the outputs of which are connected respectively with the first and second inputs of the fifth sum is robotki angle of elevation and the derivation second input of the ninth multiplier device is connected to the output of the second functional Converter, the input and second input of the tenth multiplier device is connected to the block of data about the external environment; the outputs of the third and fourth adders connected with the first inputs, respectively, of the eleventh and twelfth multiplier devices, the outputs of which are connected respectively with the first and second inputs of the sixth adder, the output of which is connected to a second input of the seventh adder, a third input connected to the output of the shaping unit pre-empt range; second input of the twelfth multiplier device is connected to the output of the third functional Converter, whose input is, and second input of the eleventh multiplier device is connected to the output of the block of data about the external environment.

There are two ways of considering the influence of deviations metabolities factors. In the first method, introduced the so-called bogus range of Df. Dfis the range from which you want to enter into the main dependence=(D) to determine the angle of aiming

The amended second way in solving the problem of the meeting involves the redesign of functional dependencies between ballistic and pre-empt coordinates f(D) and (ft(D) taking into account the deflection of factors and is reduced to solving equations of the form

wherei,tconcern is polythe increment of the function, respectively, of the angle of aiming(flight time tfloordue to the deviation of the i-th factorXi.

In literature /4, 5/ indicates that more accurate and, most importantly, with bol is the nation's ballistic calculators traditional and institutionalized form of job vneshnepoliticheskikh functions are shooting table (TC) /1, 3/.

In the main TS is the basic functional dependence=f(D), and in the correction of TC operate amendments of distance in the i-th perturbation factorXi.

Thus, according to the proposed method in the determination of the angle of sight is used the first approach. Taking into account perturbations due to meteorological factors determine the required real angle aiming:

moreover, taking into account the nonlinear dependenceD from the range D, and the size of the deviationsNT.

Graphical interpretation of the proposed method is shown in Fig.1.

In Fig.2, 3 constructed according to the revised data in accordance with the full standardized model /9/ according to the deviation rangeD respectively from the pressure of the Hinand air temperature TinD(Hin),D(Tin), built according to the standard vehicle in accordance with deviations in the range of ±10 mm RT.article and ±10With /1/.

In Fig.4, 5, similar to 2, 3, is shown for the old standard 100 mm projectile WAF.

As follows from Fig.2-5, when using linear dependenciesD(HB),D(TBwhen calculating corrections can be large systematic errors. So, for projectile WAF on firing range D=7 km at air pressure of 460 mm RT.article (N=-290 mm RT.St) error generation amendments up to 200 m (D=1150 m to the non-linear dependence andD=950 m to a linear approximation).

Errors will further increase the joint action of two or more of disturbing factors, such as low pressure and high temperature, low temperature and high pressure.

Thus, these data demonstrate the necessity of taking into account the nonlinear dependence of the deviations range from disturbing factors.

The adequacy of Fig.6, 7 shows the adjusted table and approximate dependenciesD(HB),D(TB).

As follows from the graphs, a systematic approximation error is absent when considering the values of pressure and temperature around the set in accordance with the TK range of their changes.

Analysis of the known ways of shooting BM on targets in the art is able to identify them in a collection of characteristics, which disables the claimed solution to the prototype.

Individual transactions included in the inventive method, is widely known. However, with the introduction of their way in the sequence (ties) on the proposed ratios achieved the desired effect - improving the efficiency of shooting on goal.

In the study of technical solutions in other areas of technology features that distinguish the claimed invention is a system for firing CV objective, have also not been identified.

This allows to make a conclusion about the relevance of the proposed solutions the criteria of novelty and inventive step.

In Fig.8A, 8b presents a structural diagram of circuit firing artillery weapons BM and place it claimed b is a of Fig.9 presents an example implementation of the block of adjustments in the angle of elevation on temperature and air pressure (paragraph 3 claims).

To confirm the technical feasibility of the proposed method (and system) the following is an example of its functioning.

After taking to support the objectives of the survey and sighting system in the computational system (CS) is expected to be continuous signals about the angles of the line of sight goalsandin two planes of the coordinate system associated with the mediaHTheHZHangular velocities,target coordinate system XDTheDZdand discrete measurements of the distance D (see Fig.8A, 8b). With the navigation system in the aircraft, it also receives data about the media: the speed of the carrier, the angles of pitch, roll, etc.

Previously in the armed forces should be instituted (calculated) coefficients of approximating nonlinear dependenciesD(D,Hin),D(D,TBrevised table of amendmentsD(Xi).

Data about the external environment (air pressure, temperature, speed of longitudinal and transverse wind) coming from the block of data about the external environment, for example with a single unigene calculated amendments due to the movement goal and media,and the rest of the amendments, in particular ballistic amendments to the base (parallax), on the longitudinal and transverse wind, etc., Sufficient details of their calculation are given in the literature /3/.

Before the calculation of the ballistic corrections: angle aimingand derivationdin the block of adjustments in the angle of aiming define a dummy firing range Dftaking into account perturbations due to the weather conditions -HBTB.

And, entering into the main ballistic dependence(D) since D=Dfdetermine the angle of aiming=(D,HB,TB=(Dfblock making angles of sight and derivation.

Further, the combination worked out amendments for each of the channels is supplied to the inlet metering roll angleand adjustedcontrol signals Nai communication in each moment unfold PU in the right direction.

The block of adjustments in the angle of the aiming works as follows (see Fig.9).

On the first functional Converter (FP) signal pre-empt the range of Dyin FP is squaring (D2y). The signal D2youtput FP arrives at the inputs of the third-sixth multiplier devices (MU-MU), where is domestie signal respectivelyand sending signals to the first inputs respectively of the first to fourth adders (SUM, SUM, SUM and SUM).

The signal pre-empt the range of Dysupplied respectively to the first, second, seventh and eighth multiplier device (MU, MU, MU, MU), the output of which signals are received at the second inputs of adders respectively SUM, SUM, SUM, SUM.

In the first adder SUM is the sum of signalsandin CUMandin CUMandin CUMand.

SignalTincoming from the output of the function Converter PHP, on which input signal isTincomes with unit data on the external environment. In A are multiplied coming to the first input signalon deviationTV coming from the block of data about the external environment.

In the adder SUM cumulative output multiplier devices A and A, and it turns out the correction range on the temperature deviationthat then in the seventh adder (SUM) is added to the obtained similarly by amendment of distance on the deviation of the air pressureDNand pre-empt the range of Dy. Further formed so bogus range of Dfgoes to block production of angle of elevation and derivation.

This is the block of adjustments in the angle of aiming. It can be constructed in known devices of the type multiplier unit (MU), the adder (SU), etc., a logical “and”, “or”, examples of which are widely described in the literature, for example, /6, 7/.

The use of the claimed method and realismus is their error in the whole range of changes in temperature and air pressure (in accordance with TK) and accordingly, improving the accuracy of shooting targets in terms of perturbations on meteorological factors, exceeding, respectivelyTin=±10AndHin=±10 mm RT.article.
