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.1 presents a graphical interpretation of the firing range D and the dummy range Df.On fig.2"https://img.russianpatents.com/chr/916.gif">Hinfor various shooting ranges to 100 mm projectile WAF.In Fig.3 shows the dependencies of deviations rangeD from the temperature variation of the airTBfor various shooting ranges to 100 mm projectile WAF.In Fig.4 presents the dependence of the deviation rangeD from the deviation of the air pressureHBfor various shooting ranges for the standard 100 mm projectile WAF.In Fig.5 presents the dependence of the deviation rangeD from the temperature variation of the airTBfor various shooting ranges for the standard 100 mm projectile WAF.In Fig.6 presents the dependence of the deviation rangeD from the air pressure Hinfor D=1,2...7 km and approximate dependencies for projectile WAF.In Fig.7 presents the dependence of the deviation rangeD from air temperature Tinfor D=1,2...7 km and approximate dependencies for projectile WAF.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.2. A more precise definition of the limit of ballistic firing range will allow a more efficient use of ammunition and, accordingly, to increase the effectiveness of firing the specified ammunition.3.
