The above-mentioned complex of on-board equipment provides navigation, piloting the aircraft, and the operator prepares and launches countermeasures by the pilot, but in the event of failure and disconnection of the systems included in the complex, the ability to complete assigned tasks is reduced, and the consistent solution of combat missions leads to a decrease in the efficiency of aircraft use.

The technical result of the invention is the expansion of functionality and, as a consequence of this, increasing the efficiency of using a two-seater multifunctional aircraft equipped with the proposed navigation system.

This result is achieved by the fact that the aiming and navigation complex of the equipment of a multifunctional aircraft, containing the pilot information-control system of the pilot, the information-control system of the operator, the complex of navigation and flight control equipment, the complex of sighting and sighting equipment, are interconnected by inputs and outputs on the on-board channel of information exchange control system of countermeasures, on-board computer system, including interconnected inputs and outputs about the main line of computational information exchange, the computational and logical modules of the integrated database, the formation of navigation and aerobatic parameters, the formation of aiming aerobatic parameters, the formation of displayed information, input-output and information exchange control, the other input-output of which is the input-output of the on-board computer system, is additionally equipped with computational and logical modules for the mutual correction of navigation and sighting, introduced into the onboard computer system parameters, the mutual synthesis of navigation and sighting parameters, the formation of acceptable parameters of the state of the aircraft, the simultaneous coordinated use of countermeasures interconnected by inputs and outputs, and the computational and logical modules of the integrated database, the formation of navigation and aerobatic parameters, input-output and information exchange control , the formation of sighting and flight parameters and the formation of the displayed information on the line of computational information wow exchange.

The interaction between the units of the complex and with KVDO 6 is carried out according to BKIO 7, which provides all the necessary types of electrical and mechanical interactions. The interaction between the VLM BVS 8 is carried out according to MVIO 18, which ensures the implementation of computational processes with the required speed.

The order of interaction according to BKIO 7 and MVIO 18 is carried out by WSIS 11, which provides control of BKIO 7 and MVIO 8, respectively, on one and the other inputs and outputs of WSIS 11.

IIUSL 1, IIUSO 2 are made according to the concept of interchangeability and parallel work of crew members (pilot, operator); they contain multifunctional color indicators for displaying synthesized information frames (formed in FOI 13) with call buttons (or touch buttons) for calling, assigning modes and controlling them, a collimator indicator on the windshield, multifunctional control panels for the operating modes of the complex, its components and interacting equipment from the KVDO 6, operative organs of the aircraft, engine, mating units. According to the information frames on the screens of multifunctional indicators, the indicator on the windshield, the prompt screen on the multifunctional control panels, the pilot and operator provide the formation of control signals that from the input-output of IIUSL 1 and IIUSO 2 through BKIO 7 go to the inputs and outputs of KNPS 3, KOPS 4 , SUSP 5, BVS 8, KVDO 6.

KNPS 3 contains systems and sensors of the parameters of the state of the aircraft and the air environment, the signals of which from the input-output of KNPS 3 through BKIO 7 enter the BVS 8 and KVDO 6.

COPS 4 contains survey and sighting tools that provide for the detection, selection and tracking of ground, surface, air targets and landmarks, generates the parameters of the relative motion of the aircraft relative to the targets, which constitute the speeds of the targets, which from the input-output of COPS 4 via BKIO 7 enter the BVS 8 and in the CWED 6.

SUSP 5 on the basis of the received signals generates signals for the preparation and use of active and passive countermeasures (missile, bomb, cannon weapons, dipole reflectors of radar radiation, false simulators, means of jamming), which from the input-output of SUSP 5 through BKIO 7 enter the BVS 8 and in the CWEC 6.

KVDO 6 is interacting equipment that is not part of this aiming and navigation complex - the executive units of the aircraft, propulsion system, countermeasures, information monitoring and recording devices, communications equipment with interacting aircraft and ground control and guidance points; interchange with interacting units as part of KVDO 6 is carried out through its input-output to BKIO 7.

BVS 8 is a digital calculator of monoblock or multiblock exploded design, contains computing logic modules (VLM) and MVIO 18, performed on standard elements, for example, processors and storage devices. HBS 9 is performed on a standard long-term storage device storing long-term data of standard situations, systems, countermeasures and operational data entered before flight from ground-based flight training points, while input is made from the air traffic control system 6 through BKIO 7, WSIS 11, MVIO 18.

The WSIS 11 through one input receives, converts and transfers data to the interacting equipment of the complex through the input-output of the BVS 8 and BKIO 7, and the other input-output of the WSIS 11 is connected to the MVIO 18, which carries out information exchange between the VLM of the BVS 8.

According to the data received from KNPS 3 and from OBD 9 at the input and output of the FNPP 10, the navigation and aerobatic parameters (location coordinates, components of the speed of movement, angles of evolution) of the aircraft are formed, which from the input and output of the FNPP 10 through MVOI 18 enter the interacting VLM BVS 8.

According to the data received from COPS 4, KNPS 3, OBD 9 at the entrance-exit of FPPP 12, the formation of sighting and flight parameters (coordinates and speed components relative to goals and landmarks, parameters for controlling the aircraft, preparation and use of countermeasures), which input-output FPPP 12 through MVIO 18 enter the interacting VLM BVS 8.

In FOI 13, according to the data obtained by MVIO 18 from OBD 9, FNPP 10, FPPP 12 and from interacting equipment through BKIO 7, WSIS 11, MVIO 18, generalized mnemo frames of functional, alphanumeric, television information are formed, combined with an aeronautical map of the area. The formed mnemo-frames of images at the current time from the input and output of the FOI 13 through MVIO 18, WSIS 11, BKIO 7 are sent to the display means of IIUSL 1 and IIUSO 2 for display on screens for the purpose of making decisions by crew members on working with aircraft equipment and the complex by affecting organs operational control of the aircraft and controls multifunctional remotes and multifunctional indicators.

In VKNPP 14, in relation to the FNPP 10 and FPPP 12, the navigation and piloting and sighting data are adjusted through the MKIO 18, for example, when a fixed target (landmark) is located by means of COPS 4, the coordinates of the location, horizontal components of the speed of the aircraft and the geographical course are corrected. Accordingly, the corrected navigation data generates target designation parameters with the specified coordinates and landmarks, which from the input and output of VKNPP 14 through MVOI 18 enter the FNPP 10 and FPPP 12, respectively.

In VSNPP 15, in relation to FNPP 10, FPPP 12, VKNPP 14, MVIO 18 synthesizes navigation and sighting parameters during failures and disconnections of KNPS 3 and KOPS 4. For example, when a moving target is located in FPPP 12, the target’s speed is formed, the model of which is formed in the VSNPP 15, respectively, in case of failures and disconnections of the KOPS 4 means according to the components of the aircraft speed and the target speed, the synthesized target designation parameters for the non-laden (invisible) moving target are formed, which from the VSNPP 15 input-output through MVIO 18 arrive at FPPP 12. Accordingly, in the event of failure of the means of forming the ground speed in KNPS 3 with the operating COPS 4 in the VSNPP 15, the synthesized components of the ground speed are formed (as the difference between the components of the speed of the aircraft relative to the positioned target and the components of the speed of the moving target), which output VSNPP 15 through MVIO 18 are fed to the input-output FNPP 10.

In FDSSS 16, according to the data received at its input-output through MVOI 18 from the inputs and outputs of OBD 9, FNPP 10, VVUIO 11, the areas of the current allowable interconnected parameters of the aircraft’s movement are formed — allowable angles of attack, glide, angles of evolution of the aircraft, components of the track and air the speeds that from the input-output of the FDSSS 16 through MVOI 18 go to the input-output of the FOI 13 for subsequent reflection on the screens of the means of IIUSL 1 and IIUSO 2 in order to make a decision by the crew to prevent approaching the occurrence of critical situations .

OKPSP 17 implements the possibility of simultaneous coordinated use of countermeasures by one (pilot) and another (operator) crew members. For example, in a situation where an important ground target (enemy tank convoy) is tracked by means of COPS 4 and a dangerous air target (enemy attack fighter) is detected according to OBD 9 and FPPP 12 in interaction with SUSP 5 through BKIO 7, WSIS 11, MVIO 18 in OKPSP 17, a choice is made of the available means of active counteraction, the formation of teams for their preparation and launch, which from the input-output of OKPSP 17 through MVOI 18 goes to FOI 13, from the input-output of which through MVOI 18 they go to IIUSL 1 and IIUSO 2; one and the other crew members, by independent pressing of the executive operational controls (combat buttons), form commands to launch countermeasures, which from the inputs and outputs of IIUSL 1 and IIUSO 2 through BKIO 7 enter the SUSP 5, which uses countermeasures.

Thus, the examples of technical implementation show the achievement of a technical result. The VKNPP 14, VSNPP 15, FDPSS 16, OKPSP 17 blocks additionally introduced into the BVS 8 make it possible to significantly expand the functionality of the aiming and navigation complex of the onboard equipment of a two-seat tactical multi-purpose aircraft.
