For this reason, the pilot can recognize the target aircraft 12 that has not been searched and tracked by the own aircraft, and the information on the target aircraft 12 can be shared among pilots of a plurality of aircraft 10 that are flying in formation. .

  The missile launching device 28 is a device that launches the missile 14 mounted on its own device. When the launching instruction of the missile 14 from the display instruction device 26 is input, the missile launching device 28 launches the missile 14 based on the launching instruction. The missile launcher 28 also displays on-board firearm information, which is information about the firearms mounted on its own aircraft, such as the number of bullets remaining for each type of missile 14, for example, the display instruction device 26, the data link device 24, and the fire control Output to device 30. Furthermore, the missile launching device 28 launches missiles that have been launched, such as the type of missile 14 that was fired, the position at the time of launch of the missile 14, the target aircraft 12 that is targeted (the target aircraft 12 to be guided by the missile 14), the time of launch, and so 14 is output to the fire control device 30.

  The fire control device 30 is connected to the fire control sensor 20, the navigation device 22, and the data link device 24, and based on the target aircraft information acquired by the own aircraft and the target information acquired by the convoy aircraft 10B, the target using the firearm Control the shooting of the machine 12. In the first embodiment, a case will be described in which control is performed using a missile 14 as a firearm.

Then, the target assigning unit 54 performs assignment processing for assigning the target aircraft 12 to be fired or the target aircraft 12 to be searched for tracking to the own aircraft and the wingman 10B based on the above information.

  FIG. 3 is a flowchart showing the flow of processing of the allocation candidate calculation program executed by the target allocation unit 54 when performing the allocation process. The allocation candidate calculation program is stored in advance in a predetermined area of a storage device (not shown). ing. Note that this program may be started, for example, by pressing a predetermined switch by the pilot of the allotter 10A, or at least one of the plurality of aircraft 10 performing formation flight is fire control. It may be started when the target machine 12 is detected by the sensor 20.

In the first embodiment, as shown in the schematic diagram of FIG. 4 showing an example of the positional relationship between the aircraft 10 and the target aircraft 12, a plurality of aircraft 10 perform shooting and search tracking on the plurality of target aircraft 12. The case where it performs is demonstrated. In the example of FIG. 4, the assignment machine 10A is located behind the wingman 10B. However, this is only an example, and the assignment machine 10A may be located at another position such as in front of the wingman 10B.
In the following description, as an example, when identifying and explaining the assigning machine 10A (own machine) that performs the assignment process, it is referred to as “three aircrafts”, and each of the aircrafts 10 that do not perform the assignment process (communicators 10B) is identified. In this case, it is referred to as “one machine” or “two machines”. Further, when identifying and explaining each target machine 12, any one of “# 1” to “# 4” is added to the end of “target machine”.

  First, in step 100, target position vector calculation is performed for calculating the current position, speed, and traveling direction for each target aircraft 12 from the target information.

  In the next step 102, the target aircraft 12 are sorted based on the result of the target position vector calculation. As a sorting condition, for example, the sorting is performed in ascending order of the distance from the assigning device 10A.

  In the next step 104, it is determined whether or not all the target aircraft 12 have been assigned as targets for shooting. If the determination is affirmative, the process proceeds to step 116. If the determination is negative, the process proceeds to step 106.

  In step 106, target machines 12 that cannot be assigned are extracted. The target aircraft 12 that cannot be assigned is, for example, a target aircraft 12 that takes an avoidance action on the aircraft 10 and does not fall within the range even if the missiles 14 are fired from any of the plurality of aircraft 10.

  In the next step 108, each aircraft 10 and each target aircraft 12 are obtained from the result of the target position vector calculation, the position information of the own aircraft included in the movement information of the own aircraft, and the position information of the wingman 10B included in the movement information of the wingman 10B. The distance between him and her (hereinafter referred to as “the distance between him and herself”) is calculated.

  In the next step 110, the target aircraft 12 with respect to the aircraft 10 is evaluated using a plurality of different evaluation functions that are weighted by multiplying a predetermined coefficient for each of the distance between the self, the number of remaining bullets, and the remaining fuel. A weight calculation for calculating a weight (importance) is performed.

  In the next step 112, a shooting assignment candidate calculation is performed to calculate (sort) the order of candidates of the aircraft 10 to fire for each target aircraft 12 from the calculation result of the weight calculation. Sorting conditions include, for example, the order in which the distance between the two is short, the order in which the remaining number of bullets is large, the order in which the number of already assigned target aircraft 12 is small, and the turning time until the target aircraft 12 is placed at the missile launchable angle. For example, the shortest order, the remaining fuel order.

  In the next step 114, sensor allocation candidate calculation is performed for calculating (sorting) the order of candidates of the aircraft 10 to be searched and tracked for each target aircraft 12. As a condition for sorting, for example, the target aircraft 12 is located in the coverage area of the fire control sensor 20 (hereinafter referred to as “sensor coverage area”) that is the search and tracking capability of the aircraft 10 and the distance between the aircraft is long. For example, the order in which the number of remaining bullets is small, the order in which the number of target aircraft 12 already allocated is small, the order in which the turning time until the target aircraft 12 is placed in the sensor coverage area is short, and the order in which the remaining fuel is large.

  The allocation candidate calculation program proceeds to step 104 when step 114 ends, and proceeds to step 116 when a negative determination is made in step 104 as described above.

In step 116, target candidate information indicating the assignment of the target aircraft 12 to the aircraft 10 in the order sorted by the shooting assignment candidate calculation and the sensor assignment candidate calculation is output to the display instruction device 26, and this program is terminated.
In addition, when the target candidate information from the target assignment unit 54 is input, the display instruction device 26 displays an image as shown in FIG. 5 on a predetermined screen and applies to each aircraft 10 by the pilot of the assigner 10A. Selection of assignment of the target machine 12 is accepted.

FIG. 5 is a schematic diagram showing an image displayed on the display instruction device 26 of the assigning machine 10A (three machines).
5A, 5 </ b> B, and 5 </ b> C are images showing the positional relationship between the aircraft 10 and the target aircraft 12 (hereinafter referred to as “positional relationship image 70”). The target machine 12 is displayed with a symbol (sign) and an identification number. The positional relationship image 70 is generated based on movement information of the own aircraft and the wingman 10B and target information acquired by the own aircraft and the wingman 10B.
On the other hand, the image on the right side is an image for receiving selection of assignment of the target aircraft 12 to the aircraft 10 (hereinafter referred to as “assignment image 72”), and is generated based on the target candidate information.

  The positional relationship image 70 and the assigned image 72 may be displayed on the same screen or may be displayed on different screens. However, in order to reduce the movement of the pilot's line of sight, the positional relationship image 70 and the assigned image 72 are adjacent to each other in the horizontal direction. Are preferably displayed.

FIG. 5A shows a case where assignment is selected, and a symbol indicating the target machine 12 (target machine # 1 (K1) in the example of FIG. 5A) to be assigned in the positional relationship image 70 is shown. It is highlighted and displayed. The target aircraft 12 to be assigned can be selected by pilot operation.
In the assignment image 72, a plurality of candidates for the aircraft 10 that performs shooting and the candidates for the aircraft 10 that perform search and tracking are displayed (displayed in the column "ALTERNATIVE") for the target aircraft 12 to which the assignment is performed. In the example of FIG. 5A, the combination of “SHOOT” and the number on the right next to it indicates the aircraft 10 that fires, and the combination of “GUIDE” and the number on the right next to the aircraft 10 that performs search and tracking. Show. The candidates displayed on the assigned image 72 are displayed in an order corresponding to a preset sorting condition.

  Then, as shown in the assignment image 72 in FIG. 5B, when the aircraft 10 that performs shooting and the aircraft 10 that performs search and tracking are assigned to the target aircraft 12, the positional relationship image 70 in FIG. As shown, the symbol corresponding to the assigned target aircraft 12 changes.

FIG. 5C shows a state in which the aircraft 10 that performs shooting for all the target aircraft 12 and the aircraft 10 that performs search and tracking are assigned.
In the example of FIG. 5C, the own aircraft (three aircrafts) of the aircraft 10 fires the target aircraft # 1, the wingman aircraft 10B (one aircraft) fires the target aircraft # 4, and the target aircraft # 1, # 4. The wingman 10B (two aircrafts) fires the target aircraft # 2 and # 3 and searches and tracks them.

  Note that the solid line connecting the symbol indicating the aircraft 10 and the symbol indicating the target aircraft 12 in the positional relationship image 70 is a line connecting the aircraft 10 and the target aircraft 12 targeted for shooting by the aircraft 10. On the other hand, the broken line is a line connecting the aircraft 10 and the target aircraft 12 that the aircraft 10 is a target of search and tracking. In this way, by connecting the aircraft 10 and the target aircraft 12 with a line, the pilot can easily recognize the target aircraft 12 to be fired or searched and tracked by the own aircraft and the wingman 12B.

  Then, the assigning machine 10A sends an instruction (hereinafter referred to as “target assigning instruction”) regarding the target machine 12 to be fired or the target machine 12 to be searched for tracking, assigned by the assignment process, to the data link device 24. To each wingman machine 10B.

  Note that the allocation process may generate the target aircraft 12 to be fired and the aircraft 10 to which the target aircraft 12 to be searched and tracked are not assigned. As shown in FIG. The aircraft 10 to which both the target aircraft 12 and the target aircraft 12 to be searched and tracked are assigned may be generated.

FIG. 6 is an electrical configuration diagram relating to the fire control of the aircraft 10 that is not assigned.
The electrical configuration related to the fire control of the aircraft 10 that does not perform the allocation process (the wingman 10B in the above description) is the same as that of the allocation machine 10A, but the target allocation unit 54 does not function.

  Note that the aircraft 10 that does not perform the allocation process receives the movement information of the wingman 10B including the allocator 10A and the target information acquired by the wingman 10B via the data link device 24. Therefore, the display instruction device 26 displays the position and the traveling direction of the wingman 10B based on the movement information of the wingman 10B, and the position and the traveling direction of the target machine 12 based on the target information acquired by the wingman 10B.

  Further, the aircraft 10 that does not perform the allocation process receives the target allocation instruction transmitted from the allocation machine 10A via the data link device 24, and is positioned on the screen of the display instruction device 26 based on the received target allocation instruction. The related image 70 is displayed.

FIG. 7 is an example of the positional relationship image 70 based on the target assignment instruction.
FIG. 7A is a positional relationship image 70 displayed on the screen of the display instruction device 26 provided in the aircraft 10 (one aircraft) in FIG. On the other hand, FIG. 7B is a positional relationship image 70 displayed on the screen of the display instruction device 26 provided in the aircraft 10 (two) in FIG.

The display shoots the target aircraft # 4 against the aircraft 10 (one aircraft) and continues to search and track the target aircraft # 1 and # 4 within the sensor coverage area, and also via the data link device 24. An instruction to transmit the target information of the target machines # 1 and # 4 to the wingman machine 10B is shown.

Further, the positional relationship image 70 illustrates that the target machine # 4 is a target of shooting by connecting a symbol indicating the own machine and a symbol indicating the target machine # 4 with a solid line, and the symbol indicating the own machine and the target By connecting the symbols indicating the machines # 1 and # 4 with broken lines, it is illustrated that the target machines # 1 and # 4 are the targets of search and tracking. The positional relationship image 70 also illustrates the position of the wingman 10B.
Note that the positional relationship image 70 also illustrates the aircraft 10 (three aircrafts) that target the target aircraft # 1 that is the target of search and tracking of the own aircraft, so the pilot of the aircraft 10 (three aircraft) that is the own aircraft is also illustrated. Can easily recognize the wingman 10B whose target is the target aircraft 12 to be searched and tracked.

  On the other hand, as shown in FIG. 7B, the positional relationship image 70 of the aircraft 10 (two) is displayed as “SHOOT: K2 SHOOT: K3 GUIDE: K2 GUIDE: K3”. The display shoots the target aircraft # 2 and # 3 against the aircraft 10 (two aircraft), and continues to search and track the target aircraft # 2 and # 3 within the sensor coverage area. The instruction to transmit the target information of the target machines # 2 and # 3 to the wingman 10B is shown.

It is illustrated that the target aircraft # 2 and # 3 are the targets of search and tracking by connecting the symbol indicating the aircraft and the symbols indicating the target aircraft # 2 and # 3 with broken lines.

In the aircraft 10 according to the first embodiment, the allocation machine 10A can be changed.
For example, among the aircrafts 10 in which priorities are set in advance for a plurality of aircraft 10 performing formation flight and various information can be transmitted and received through the data link, the aircraft 10 having the highest priority is assigned to the assigner 10A. Is done.

  For this reason, when the assigning machine 10A leaves for some reason and cannot transmit / receive various types of information to / from the wingman 10B via the data link, the receiving of information from the assigning machine 10A is interrupted, and the next priority is given. The aircraft 10 with the higher rank automatically becomes the assigner 10A. Thereby, it can prevent that the aircraft 10 which performs an allocation process does not exist.

  Allocation machine 10A may be determined by selection by a pilot via display instruction device 26, instead of being determined by priority. Further, the assigned machine 10A may be changed to another aircraft 10 without leaving the assigned machine 10A, or an aircraft 10 that is not designated as the assigned machine 10A may be set in advance.

  As described above, the aircraft 10 (assignment aircraft 10A) according to the first embodiment receives the movement information of the wingman 10B from the wingman 10B and the target information acquired by the wingman 10B through search and tracking by the data link device 24. Then, the movement information of the own aircraft and the target information acquired by the own aircraft by search and tracking are transmitted to the wingman 10B. Then, the aircraft 10 uses the target allocation unit 54 based on the movement information and target information of the wingman 10B received by the data link device 24, and the target information acquired by the movement information of the own aircraft and the search and tracking of the own aircraft. The allocation process for allocating the target aircraft 12 to be fired or the target aircraft 12 to be searched for tracking is performed on the aircraft and the wingman 10B, and the target allocation instruction as the allocation result is transmitted to the wingman 10B by the data link device 24. To do.

In other words, the allocation process is a process in which the allocation machine 10A allocates a target to be fired or a target to be searched for tracking to the wingman 10B. 12 can be prevented from being shot, and generation of the target machine 12 leaking from the target of shooting can be prevented. Further, the allocation process can efficiently search and track the target aircraft 12, and can prevent the target aircraft 12 from leaking from the search and tracking target.
Further, the aircraft 10 according to the first embodiment shares target information with the wingman 10B via the data link device 24. Therefore, even if the target aircraft 12 cannot be searched and tracked by the own aircraft, the own aircraft can shoot the target aircraft 12 that the wingman 10B can search and track.

  Therefore, the aircraft 10 according to the first embodiment can efficiently perform firearm control for shooting the target aircraft 12.
