In the process of conducting hostilities, as a rule, the following stages of accomplishing the task of hitting an air target are distinguished, which are determined by the operating modes of the ACS when operating against an air target:

- long-range guidance;

- overview (search and target identification); target allocation;

- close guidance;

- exit from the attack.

Long-range guidance refers to the control of the MFS for target designation from a guidance point or a leader to bring it into locating contact with a target with certain conditions in terms of relative position at the time the target is detected by onboard means. In this case, the fighter can be controlled from the control point (CP) automatically or manually.

The main tasks for long-range guidance are:

- determination of the coordinates of the target relative to the fighter;

- selection of the aiming point, taking into account the movement of the target.

With long-range guidance on board the aircraft from the launcher, the following basic commands are transmitted via the command line:

- given speed, altitude, course or track angle;

- range to the target, speed of convergence with the target, azimuth and elevation of the target;

- one-time commands (turning on the radar, turning, etc.);

- control of the field of view of the FSA.

The stage of long-range guidance ends with the withdrawal of the aircraft into the vicinity of the target and the organization of the "Review" mode.

The "Survey" stage begins from the moment the pilot is notified from the launcher about the need to switch the surveillance and targeting system (OPS) into the airspace survey mode. The type of FSA sighting device used in the "Overview" mode is selected based on the tactical and meteorological situation (RLPK or OLS).

The "Overview" stage ends with the assignment of a target for attack (target distribution) and the transition of the FSA to the "continuous direction finding" mode (tracking one target).

Target assignment includes the selection of a target for an attack and can be carried out on board an aircraft or at a control room automatically or manually. In this case, each aircraft is assigned its own target.

If the pilot does not agree with the automatic assignment of a target for an attack, he can use the controls to manually select a target that has a higher priority.

Under fixed conditions of attack, targets, the possibility of using the missile launcher are unambiguously characterized by the launch area and the area of initial positions for entering the launch area.

Launch area - the space near the target, within which an aimed missile launch is possible, ensuring successful guidance, reliable detonation of the fuse and hitting the target of the warhead.

The dimensions and shape of the launch area for certain attack conditions depend on the energy ballistic characteristics of the missile launcher, control equipment and the maneuverable capabilities of the attacking aircraft when aiming and launching the missile launcher.

In this case, the launch area has a near and far boundaries, which are separated from the target by D _max (q) and D _min (q), respectively. When the launch area is limited by the heading angle of the target q, lateral boundaries D (q) appear, and when attacking in the vertical plane, the upper and lower boundaries appear.

FIG. 4, 5 show a cross-section of the launch area of an all-aspect rocket in the horizontal and vertical planes.

The far border is influenced by:

- the time of the controlled flight of the rocket;

- the minimum speed of the approach of the missile launcher with the target, at which the reliable operation of the proximity fuse is ensured;

- available overload of the missile launcher on the trajectory;

- the maximum angle of deviation of the coordinator;

- range of target capture by the coordinator.

The near border is influenced by:

- cocking time of the fuse t _vzv ;

- time to enter the guidance trajectory (elimination of launch errors);

- the time of transient processes from the moment of launch to the beginning of sustainable guidance of the missile launcher (for the missile launcher with a command guidance system);

- the maximum speed of the approach of the UR with the target, at which the proximity fuse V _Dmax reliably operates.

The lateral boundaries are influenced by:

- the maximum angle of deflection of the coordinator ϕ _to ;

;- maximum angular velocity of the coordinator

;

- the ability of the coordinator to accompany the target from large angles;

- the method of launch (at a calculated lead angle or direct fire).

For an approximate calculation of the firing area, they are used by graphic-analytical methods, taking into account only the main, most significant factors.

BVS 18 ([4], p. 17; [6], p. 30, 474-478) is a digital computing machine of compact monoblock or multi-unit spaced-out design, while computing and logic modules (FNP 21, FPCP 23, FOI 24, RVV 25, ISTs 26, FPE 27, DVB 28, DBP 29, BVB 30, BBP 31) are executed on standard computing circuits based on one or more processors and memory devices of various types.

MVO 19 [6], carries out information interconnection for data transfer between the inputs-outputs of the VLM BVS 17 via the computational exchange highway.

OBD 20 is made on a standard long-term storage device storing operational data transmitted from PNID 16 and long-term data of stationary parameters and situations for combat and combat training of the aircraft; VVUO 21 through one input-output receives, converts and transfers data to the interacting equipment through the input-output of BVS 17 through BKIO 3, and the other input-output of VVUO 21 is connected to MB O 18, which carries out information and computational exchange between computational and logical modules BVS 17.

In FNP 20, complex processing of information from KNPS 2, KOLS 4, RLPS 6, KSRP 7 with initial data from OBD 19 is carried out and flight and navigation parameters are formed (in all flight modes from takeoff to landing and stopping and during all types of preparations and verification works), which from the input-output of FNP 20 through the MVO 18 enter the interacting computational and logical modules, including the VVUO 21 for transmission through the input-output of the BVS 17 and BKIO 3 to the interacting systems.

In FPTsP 22, complex processing of information from the means of KOLS 4, RLPS 6, KSRP 7, KSPP 9, KNPS 2 is carried out and the aiming parameters of target designation and application are formed, which from the input-output of the FPTsP 22 through MVO 18 enter the interacting computational and logical modules, in including at VVUO 21 for transmission through the input-output BVS 17 and BKIO 3 to the interacting equipment.

In FOI 23, according to the data obtained by MVO 18 from OBD 19, FNP 20, FPCP 22 and from the interacting equipment through BKIO 3, VVUO 20, generalized mnemonic frames of functional, alphanumeric, television information are formed, if necessary combined with an aeronautical map of the terrain and presentation of a multifunctional control panel. The generated mnemonic frames of images corresponding to the operating modes of the aircraft and equipment, at the current time from the input-output of FOI 23 through MVO 18, VVUO 21, BKIO 3 enter SKR 1 for recording, to SCSS 10, for example, for transmission to interacting objects and ground points control, in MFIP 11, KITK 12, MFIV 16 (with a single object and a two-seat combat training aircraft) for display on screens for the purpose of making decisions by the crew.

The armament control system of a multifunctional aircraft works as follows.

Before the flight, a multifunctional tactical aircraft is equipped with aviation weapons, provides input into the operational database 19 from a portable carrier 15 of the initial data on flight parameters (parameters of airfields, targets, characteristics of operating modes of the weapon control system in flight, text data for indicators used by aviation means of destruction). Provide power supply from onboard sources during the preparation and use of aviation weapons and passive countermeasures, issuing signals to identify the weapons on board, their condition and installation locations,

To turn the aircraft into operation (for example, after takeoff), data from PNID 15 through BKIO 3, VVUO 21, MVO 18 are transferred to ATS 19, where they are stored during the flight and used to solve problems by interacting computational and logical modules, while PNID 15 is released for the subsequent reception and recording of the necessary information, including in the current flight.

In FPE 26, for interaction through MVO 18 with other computing and logical modules BVS 17 and onboard equipment interacting through VVUO 21, BKIO 3, parameters of emergency flight analysis are formed, for example: coordinates and characteristics of newly detected targets, results of work in flight of an aircraft and equipment that require conducting operational ground analysis, mnemonic frames of operational television information based on the results of reconnaissance or combat use,

which from the input-output FPE 26 through MVO 18, VVUO 21, BKIO 3 enter the input-output PNID 15 for recording and subsequent playback after the flight. At the same time, the playback of the recording is possible without removing the PNID 15 from the aircraft on the means of MFIP 11, MFIV 16, as well as when removing the PNID 15 from the aircraft at ground points for analyzing flight results and planning operations.

_{Signals of Doppler shifts of the radiation frequency spectrum ω gi} and the reflection characteristics of airspace, water and earth surfaces x _ki are received from RLPS 6 through BKIO 3, VVUO 21, MVO 18 in RVV 24 and ISC 25. From the OBD 19 through the MVO 18, VVUO 21, the specified parameters ω _HP , ω _VS are supplied to the RVV 24, and the specified parameters are supplied to the ISC 25.

When operating on helicopters in hover mode, the Doppler frequency spectrum has maxima at the frequency ω _{l of} rotation of the helicopter blades and at the frequency of the vibration of the helicopter body. In RVV 25, the standard method of searching for the maximum similarity of ω _in and ω _VS , ω _L and ω _HP determines the helicopter as the target and target designation parameters, these data from the RVV 25 input-output through the MVO 18 are fed to the FPTsP 22 (for the formation of target designation and the selection of the applied means from the KSPP 9), in the FOI 23 (to display the detected target on the mnemonic frames MFIP 11, MFIV 16, KITK 12) and through VVUO 21, BKIO 3 into the interacting equipment, for example, in SKR 1 for registration and in the SSSO 10 for transmission to interacting objects and ground control points.

When the radar station 6 operates on the earth's surface in accordance with the geometry of the radiation and the current angular position of the aircraft (heading, roll and pitch angles), the Doppler shifts of the _{radiation frequencies ω gi} are proportional to the components of the ground speed in the direction of radiation. From the set of cog; the ISC 25 receives the measured subset (subsets) of ω _qi with the highest or characteristic radar contrast, while the radiation opening angle can be narrowed to sizes that provide optimal location of a small-sized ground target (such as a single tank, mobile anti-aircraft missile system) for fixing it with resolution 2-3 m.

In ISC 25, based on the received signals, standard functionals of maximum similarity x _ki and x _{k are formed} , which are used to determine small-sized ground targets that are hardly noticeable in the radar spectrum of radiation, which make up the ground speed of these targets relative to the earth's surface and target designation parameters, which from the input-output of the ISC 25 through MVO 18 enter FPCP 22 to select means of destruction from the KSPP 9, form target designation and use it in FOI 23 to represent the target on mnemonic frames MFIP 11, KITK 12 and MFIV 16.

Computing and logical modules DVB 27, DBP 28, BVB 29, BBP 30 are operational and advisory tools that help the pilot (in single combat performance) and the pilot and operator (in double combat performance) to carry out specific control of aircraft armament in accordance with situations.

At the same time, in the situation of detecting a ground target and at the same time an attacking enemy fighter, the means of tracking, destruction, indication modes, the method and procedure for performing a maneuver against a possible enemy attack and own attack are assigned, cyclograms of preparation and launch of the selected means and the procedure for performing the maneuver are formed based on the optimization of the functional conditions survival and combat mission solutions, issue recommendations to the pilot on actions in the current situation based on the receipt of commands on the indication means from the computational and logical elements of long-range air combat or long-range combat on the surface.

For example, in a single-seat combat version of an aircraft, when a radar station 6 of a distant air target (bomber or enemy helicopter) is detected, and by means of KSRP 7, the fact of irradiation of the aircraft with radar radiation (from ground or air defense systems of the enemy) is recorded in DVB 27: from the composition of KSPP 9, means are assigned destruction of the detected target - medium and long-range air-to-air missiles with a thermal and active radar homing head, passive countermeasures are assigned from the KSPP 9 (false radar targets - dipole radar reflectors), from the KSRP 6, active jamming means are assigned , on the basis of optimizing the functional of the effectiveness of solving a combat mission, a cyclogram of preparation and launching of countermeasures, the use of active and passive countermeasures, disabling and enabling radar 6 is formed, modes and sub-modes of operation of MFIP 11, MFIV 16, KITK 12 are automatically or manually assigned.

By interacting with TOC 13, the pilot uses the designated means and provides control of the aircraft operating in the interceptor and jammer mode.

For example, with the two-seat combat use of the aircraft by means of radar 6, a distant newly detected ground target (a group of enemy tanks) was recorded. In this case, the target parameters are entered into PNID 15 through FPE 26, at the same time by means of KOLS 4 an attacking enemy fighter (dangerous air target) was detected, in DBP 28: escort means are assigned - RLPS 6 for the operator's work, KOLS 4 for the pilot's work, weapons are assigned from composition of KSPP 9 - medium and long-range air-to-surface missiles (for the operator), highly maneuverable short-range air-to-air missiles (for the pilot), indication modes MFIP 11, KITK 12, MFIV 16 are assigned for indicators at the pilot's and operator's workplaces , a method and procedure for performing a maneuver against a possible enemy attack and own attack is assigned, based on the optimization of the functional of survival conditions and solving a combat mission, a cyclogram of preparation and launch of the selected means is formed, the procedure for performing a maneuver and performing a flight after using the means on the main (ground) target.

The generated commands are sent from the DBP 28 to the pilot and operator's display and control means, which, through the OOU 13, provide control of the weapon system in connection with the current situation.

Thus, the aircraft simultaneously performs the functions of a bomber, jammer, fighter and operational reconnaissance.

When conducting close air combat in a situation where the aircraft is simultaneously used as a fighter and as a jammer, they ensure the selection of the most dangerous target, designate means of destruction, active and passive counteraction, the method and procedure for performing maneuvers, work with target tracking means, form a cyclogram of preparation and use of the selected aviation weapons based on the optimization of the functional of the maximum possible defeat of the enemy and the minimum of their own losses.

For example, in a single-seat combat performance, several short-range air targets are detected and accompanied by means of KOLS 4 and RLPS 6, in BVB 29:

- the choice of the most dangerous target is carried out,

- means of destruction, active and passive counteraction are assigned,

- the method and order of maneuvering is assigned,

- the order of work with KOLS 4, RLPS 6 is assigned,

- based on the optimization of the functional of the maximum possible defeat of the enemy and the minimum of its own losses, a cyclogram of the preparation and use of the selected means is formed.

In accordance with the developed commands received from BVB 29 at MFIP 11, KITK 12, MFIV 16, the pilot, interacting with the OU 13, provides control of the SUV in the current situation of the combat flight of the aircraft, which functions as a fighter and jammer.

In the situation of fixing the fact of aircraft irradiation from radar means of a mobile anti-aircraft missile system of the enemy, means of destruction and passive counteraction, active counteraction, the procedure for performing work for the crew, the method and procedure for performing anti-aircraft maneuvering and maneuvering of the subsequent possible attack, form a schedule for the preparation and launch of means of destruction and passive counteraction, combat maneuvering based on the optimization of the functional of minimum own losses, maximum possible defeat of the enemy, while giving recommendations on the actions of the crew in the current situation, based on the indication of commands coming from the logic module of close air combat or close air combat on the surface.

For example, in a two-seat (pilot, operator) combat use of the aircraft by means of KOLS 4, RLPS 6, a near ground target was detected - a mobile launcher of the enemy and by means of KSRP 7, the fact of irradiation of the aircraft from radar equipment of a mobile anti-aircraft missile system of the enemy was recorded, in BVP 30:

- assigned means of destruction and passive counteraction from the KSPP 9,

- means of active counteraction from the KSRP 7 are assigned,

- the order of performance of work by the pilot and the operator is assigned,

- the method and procedure for performing anti-aircraft maneuvering and the maneuver of the subsequent possible attack are assigned,

- based on the optimization of the functional of the minimum own losses, the maximum possible defeat of the enemy, a schedule is formed for the preparation and launch of weapons and passive countermeasures, disabling the radar station 6, and performing combat maneuvers.

The generated commands from the BVP 30 are sent to the pilot and operator's display and control means, which, through the OU 13, provide control of the aircraft, which functions as an attack aircraft and jammer. The functioning of DVB 27, DBP 28, BVB 29, BBP 30 is also carried out in a training flight with a two-seater combat training aircraft with the play of situations stored in WDS 19.

KOLS 4, together with BAPDTS 5, provides correction of target designations for guided missiles in the event of a change in target maneuver.

This happens as follows, from the output of KOLS 4, signals proportional to the angular position of the target are fed to the input of the unit 5 for analyzing the parameters of the target movement and, accordingly, to the input of the adder 47, the second inputs of the first 43, second 44 and third 45 dividers, the first inputs of the threshold devices 32, and the second inputs receive signals from the outputs of the signal generator 48, thereby providing discretization of the angular positions of the target in the process of its tracking by KOLS 7.

The discrete values of the angular positions of the target from the output of the threshold devices 32 through the OR element 33 are fed to the first inputs of the shift register 35, which are reset to zero before starting work in conjunction with the counters 40, 41, 42 by supplying a signal from the output of the differentiating circuit 49 from the power source.

The signals arriving alternately from the first, second and third outputs of the shift register 35 to the first inputs of the first 37, second 38 and third 39 of the AND elements, provide signals from the output of the pulse generator 36 to the first inputs of the first 40, second 41 and third 42 counters, which provide measurements of time intervals between incoming discrete angular positions of the target, while these signals are fed to the first inputs of the first 43, second 44 and third 45 dividers, to the second inputs of which signals are received from the first input of the unit 5 for analyzing target movement parameters.

From the outputs of the dividers (43, 44, 45), signals proportional to the angular velocities of the target are fed through the second 34 OR element, the integrator 46 to the first input of the adder 47.

At the output of the adder 47, a signal of the predicted angular position of the target is generated, which takes into account the angular velocity of the target, this signal is fed to the input of the control system for the means of destruction and passive counteraction, thereby increasing the accuracy of target designation for guided missiles.

KOLS 4 together with BAPDTS 5 and BOZVPR 6 provides an attack of an air target in conditions of covert observation of it.

When approaching an air target in the case of its movement in three-dimensional space along a rectilinear trajectory ε _g = ε _in = 0, a system of equations is drawn up that describes the mutual movements of the aircraft.

The system of equations in vector form (for a "flat" problem, for example, in the XOY plane), which determines the position of aircraft in the process of rendezvous, is presented in the form:

In scalar form, this system of equations is presented in the form:

We denote D _1в = X _{1 '} D _2в = X _2' D _3в = X ₃ , L _q = X ₄ , then the system (2) in the canonical form will take the form:

We transform system (3) into the following form:

Taking into account (3) and (4), the parameters of the target movement in the vertical plane:

In the XOZ plane, we get similar dependencies, replacing the index "c" in them with the index "r".

Having the parameters of the CC in the horizontal and vertical planes, we find the parameters of the CC motion for the case of the three-dimensional problem in Fig. 3, because

Taking into account (7), we get:

BOZVPR 6, determines the moment of issuing the command to the rocket "Start allowed", in accordance with the block operation algorithm (Fig. 6a, Fig. 6b) when the current range and angular position of the set values (Figs. 4, 5) are reached in the form of the expression:

where D _m , P _m are the current ranges and angular positions of the MFS relative to the air target, OVP are the parameters of the area of possible missile launches.

Thus, the proposed armament control of a multifunctional aircraft based on an interactive information and display system ensures the performance of the training and combat functions of a fighter, interceptor, bomber, attack aircraft, jammer and operational reconnaissance aircraft coordinated in space and time, increasing the accuracy of targeting guided missiles in conditions of target maneuvering. and expanding the functionality by ensuring the possibility of launching missiles in conditions of covert observation of the target, while the target moves along a straight trajectory.
