The expanded program is expanded, and various processes are executed in cooperation with the expanded program.

[Operation]
Next, an operation when the aircraft 10 executes the attack content setting process will be described with reference to FIGS.
FIG. 5 is a flowchart showing the flow of the attack content setting process, FIG. 6 is a flowchart showing the flow of the attack position calculation process executed in the attack content setting process, and FIG. It is a figure for demonstrating the positional relationship of the altitude with the target 20, and FIGS. 8-10 is a figure for demonstrating attack content setting processing.

  The attack content setting process is a process of setting an optimum attack position FP for performing an attack on the attack target area KZ where the attack target 20 is present and then searching for an optimum flight path to the attack position FP. is there. This attack content setting process is executed by the control unit 18 reading out and developing the attack content setting program 150 from the storage unit 15 when an instruction to execute the attack content setting process is input by a pilot operation.

  As shown in FIG. 5, when the attack content setting process is executed, the control unit 18 first receives input of various information necessary for the process by the pilot's operation and stores it in the storage unit 15 (step S1). . Here, the various types of information include the aircraft 10 model, the type of bullet used, the mission start position FARP and the coordinates of the attack target area KZ, scheduled departure time and arrival request time, fuel amount, cruise speed, etc. Such information includes enemy power range information.

  Next, the control unit 18 calculates an enemy effective range ADU within a predetermined range including the mission start position FARP and the attack target area KZ (step S2). This enemy effective zone ADU is a range in which there is a possibility of being attacked by an enemy force, and is calculated based on the position of the enemy force, information on the anti-aircraft weapons possessed, and the like. Then, the control unit 18 stores the calculated enemy effective zone ADU in the storage unit 15 and displays it on the map data 155 read from the storage unit 15 and displays the map data 155 on the display of the display unit 14 (FIG. 8 (a)).

  Next, the control unit 18 executes an attack position calculation process for calculating the attack position FP (coordinates thereof) (step S3). This attack position calculation process is executed by the control unit 18 reading the attack position calculation program 151 from the storage unit 15 and developing it.

  In this attack position calculation process, as shown in FIG. 6, the control unit 18 first maps a predetermined range of map data 155 including the mission start position FARP and the attack target area KZ into a plurality of grids M,. Divide (step S31). Here, for example, the control unit 18 generates a plurality of grids M, 50 m square by dividing lines along the north-south and east-west directions (FIG. 8B).

  Next, the control unit 18 selects a grid M satisfying a predetermined attackable condition from a plurality of grids M,... In the map data 155 divided in step S31, and selects the grid M as the attack position number. One candidate FPc1 is set (step S32). Here, the attack possible condition is a condition for evaluating whether or not the attack target 20 is attackable with respect to three points of “mission feasibility”, “accuracy” and “survivability”.

Specifically, in step S32, the control unit 18 reaches the distance from the mission start position FARP based on the amount of fuel (remaining amount) stored in the storage unit 15 as a condition regarding “mission feasibility”. A grid M within a possible range is selected.
Further, the control unit 18 sets the range of the range of the aircraft 10 around the attack target area KZ (attack target 20) based on the used bullet type and the like stored in the storage unit 15 as a condition relating to “accuracy”. A grid M located inside is selected.
Further, the control unit 18 selects a terrain grid M that is easy to avoid an attack from the attack target 20 based on the map data 155 stored in the storage unit 15 as a condition regarding “survival”. Here, “the terrain that is easy to avoid an attack from the attack target 20” is a terrain in which a shield that can be hidden from the attack target 20 exists between the attack target 20 as shown in FIG. This is a terrain that can move to the attack height H2 that can attack the attack target 20 by rising within the predetermined altitude (for example, 100 ft) from the retreat height H1 at this time. The evacuation altitude H1 is assumed to be an altitude of 150 ft or more from the ground surface in consideration of the altitude range (about 100 ft) capable of maintaining a stable flight state and the height of vegetation (about 50 ft).

In this way, the control unit 18 selects a lattice M that satisfies all the above three conditions and sets it as the attack position first candidate FPc1. In this embodiment, as shown in FIG. 9A, it is assumed that eight lattices M,... Are set as attack position first candidates FPc1.
When there is no lattice M that satisfies all the conditions, the control unit 18 may terminate the process because it is impossible to perform the task, or relax the conditions as much as possible based on the pilot's operation. In addition, the attack position first candidate FPc1 may be reset.

Next, as shown in FIG. 6, the control unit 18 determines the mission start position FARP without being found by the enemy forces from the plurality of lattices M,... Set in the attack position first candidate FPc1 in step S32. The lattice M that can be reached from is selected, and the lattice M is set as the second attack position candidate FPc2 (step S33). Specifically, based on the map data 155 and enemy force range information stored in the storage unit 15, the control unit 18 passes through a point where a predetermined distance can be secured from the enemy force or it can be hidden by a shield. Then, the lattice M that can be reached is selected from the plurality of lattices M,... Set as the attack position first candidate FPc1, and set as the attack position second candidate FPc2.
If the corresponding grid M does not exist, the control unit 18 may terminate the process because it is impossible to perform the mission, or may attack after relaxing the conditions as much as possible based on the pilot's operation. The position second candidate FPc2 may be reset.

  Next, the control unit 18 quantifies “mission feasibility”, “accuracy”, and “survivability” for each of the plurality of grids M,... Set for the second attack position candidate FPc2 in step S33. P is calculated (step S34). This score P is a quantitative evaluation of the suitability of each grid M set as the attack position second candidate FPc2 as the attack position FP with respect to three points of "mission feasibility", "accuracy" and "survivability". The higher the value, the higher the suitability as the attack position FP.

Specifically, in step S34, the control unit 18 calculates the number P of each grid M set as the second attack position candidate FPc2 using the following equation 1.
P = P1 + P2 + P3 (Formula 1)

Here, P1 is a value obtained by quantifying the suitability of the lattice M to be calculated regarding the “mission feasibility (ease of pilot shooting)”, and is calculated using the following Equation 2.
P1 = a × (FOF suitability value) + b × (shooting angle suitability value) + c × (terrain suitability value)
... (Formula 2)
In the right side of Equation 2, a to c are predetermined coefficients.
The “FOF (Field Of Fire) suitability value” is obtained by scoring the peripheral viewing angle when the aircraft 10 (pilot) on the corresponding grid M visually recognizes the attack target 20 at the attack altitude H2. The “FOF suitability value” is based on the map data 155 and the first evaluation table 156a (see FIG. 3A), and the wider the peripheral viewing angle that can be secured in the corresponding grid M (the more open the surrounding terrain is). ) Calculated to get a high score.
Further, the “shooting depression angle suitability value” is obtained by scoring the shooting depression angle α when the aircraft 10 in the corresponding grid M attacks the attack target 20 at the attack altitude H2, as shown in FIG. This “shooting depression angle aptitude value” is calculated based on the map data 155, after calculating the shooting depression angle α from the horizontal distance L and altitude difference H between the aircraft 10 and the attack target 20 on the corresponding grid M, Based on the table 156b (see FIG. 3 (b)), the highest score is obtained when the shooting depression angle α is within the depression angle limit value, and the higher the score is, the smaller the difference is, the smaller the difference is. Calculated. Here, the depression angle limit value is a value determined by the type of firearms used in the aircraft 10 and the like.
Further, the “terrain suitability value” is obtained by scoring the topography of the corresponding grid M by the degree of opening of the land from the viewpoint of ease of shooting by the pilot. Based on the map data 155 and the third evaluation table 156c (see FIG. 3 (c)), this “terrain suitability value” indicates a higher score as the land of the corresponding grid M is opened, and there are more obstacles. The lower the score, the higher the score.

Further, P2 in Equation 1 is a value obtained by quantifying the aptitude of “lattice accuracy (ease of hitting)” of the lattice M to be calculated, and is calculated using Equation 3 below.
P2 = d × (Shooting distance suitability value A) + e × (Shooting altitude difference suitability value) (Equation 3)
In the right side of Equation 3, d and e are predetermined coefficients.
Further, the “shooting distance suitability value A” is obtained by scoring the horizontal distance L between the aircraft 10 and the attack target 20 in the corresponding grid M from the viewpoint of the characteristics of the firearm used. This “shooting distance suitability value A” is based on the fourth evaluation table 156d (see FIG. 4A) and becomes the highest score when the horizontal distance L is almost the best range of the firearm used. The higher the difference from the best range of firearms, the lower the score.
The “firing height difference aptitude value” is a point indicating the altitude difference H between the attack altitude H2 of the aircraft 10 and the altitude of the attack target 20 at the corresponding lattice M from the viewpoint of the physical hit of the shell. It has become. As the altitude difference H increases, the straightness of the shell increases and the exposed area of the attack target 20 increases, so that the accuracy of shooting is improved. Therefore, the “shooting altitude difference suitability value” is calculated based on the fifth evaluation table 156e (see FIG. 4B) so that the higher the altitude difference H, the higher the score.

In addition, P3 in Equation 1 is a value obtained by quantifying the aptitude for “survivability (ease of avoidance of attack from the attack target 20)” of the lattice M to be calculated, and is calculated using Equation 4 below. Is done.
P3 = f × (background suitability value) + g × (shooting distance suitability value B) (Expression 4)
In the right side of Equation 4, f and g are predetermined coefficients.
The “background suitability value” is obtained by scoring the background when the aircraft 10 positioned at the attack altitude H2 in the corresponding grid M is viewed from the attack target 20. This “background suitability value” is based on the sixth evaluation table 156f (see FIG. 4C). When the background is a terrain (for example, mountain surface), the score is high, and when the background is empty, the score is low. Is calculated as follows.
“Shooting distance suitability value B” is a score obtained by scoring the horizontal distance L between the aircraft 10 and the attack target 20 in the corresponding grid M from the viewpoint of easy avoidance of an attack from the attack target 20. It is. This “shooting distance suitability value B” is calculated based on the seventh evaluation table 156g (see FIG. 4D) so that the higher the horizontal distance L, the higher the score.

Next, as shown in FIG. 6, the control unit 18 has a high score P calculated in step S34 among the plurality of grids M,... Set for the second attack position candidate FPc2 (higher predetermined number). And the selected grid M is set as the attack position final candidate FPc3 (step S35). In the present embodiment, as shown in FIG. 9B, it is assumed that two lattices M are set as the attack position final candidate FPc3. Then, the control unit 18 displays a plurality of grids M,... Set as the attack position final candidate FPc3 on the map data 155 in the display. At this time, it is preferable that the plurality of final attack position candidates FPc3,... Displayed in the display are color-coded and displayed in order of the score P, for example, so that the pilot can easily determine the level of the score P. .
Thus, the attack position calculation process ends.

  Next, as shown in FIG. 5, the control unit 18 selects any one of the plurality of final attack position candidates FPc 3,... Displayed on the map data 155 based on the signal from the operation unit 13. Is determined (step S4). That is, in this step S4, it is determined whether or not the pilot selects any one of the plurality of final attack position candidates FPc3,.

  In this step S4, when it determines with any one being not selected from several attack position final candidate FPc3 ... (step S4; No), the control part 18 transfers a process to the above-mentioned step S3. In this case, the pilot does not select the desired attack position final candidate FPc3,..., But does not select it, and executes the attack position calculation process in step S3 again by changing the calculation condition or the like.

  In Step S4, when it is determined that any one of the plurality of final attack position candidates FPc3,... Is selected (Step S4; Yes), the control unit 18 selects the final attack position candidate FPc3 as the attack position FP. (FIG. 10A), a flight path search process for searching for a flight path from the mission start position FARP to the attack position FP is executed (step S5). This flight route search process is executed by the control unit 18 reading the flight route search program 152 from the storage unit 15 and developing it.

  In this flight route search process, the control unit 18 calculates a score related to the degree of attack avoidance of each grid M within the predetermined range of map data 155 including the mission start position FARP and the attack location FP, and starts the mission based on the score. The flight path from the position FARP to the attack position FP is searched. The score related to the degree of attack avoidance indicates the ease of avoiding attacks from enemy forces when the aircraft 10 flies over the corresponding grid M, and means that the lower the value, the easier the attack is avoided.

Specifically, in this flight route search process, first, the control unit 18 uses the presence of enemy forces and the degree of opening of the land as additional points based on the map data 155 and the enemy force range information stored in the storage unit 15. Then, the score regarding the degree of attack avoidance of each grid M is calculated using the degree of shielding of the land as a deduction factor. Further, the control unit 18 calculates a travel time and a required fuel amount that can be used from the mission start position FARP to the attack position FP based on the mission content and the like. And the control part 18 can move within the range of the calculated movement time and required fuel amount among the flight paths from the mission start position FARP to the attack position FP, and the sum of the points in the flight path is the minimum. .. Are searched for and set as the optimum flight path R _opt (FIG. 10B).

At this time, the control unit 18 sets a stray position HP where the attack position FP can be visually recognized in the optimum flight route _Ropt . Specifically, the control unit 18 sets a plurality of candidate points for the hovering position HP in advance, searches the optimum flight route R _opt so as to always pass through any of these candidate points, and finds the searched optimum point. and it sets the candidate point in the flight path R _opt as hovering position HP.
The control unit 18 includes a moving time and the required amount of fuel when moving from mission start position FARP to attack position FP along the optimum flight path R _opt set, combat available time and use in an attack position FP at that time Calculate possible fuel amount.
Thus, the flight route search process ends.

Next, the control unit 18 displays the optimum flight route R _opt set in step S5 on the map data 155 of the display, and also displays various status information such as the battleable time and the usable fuel amount on the display. (Step S6).

Next, the control unit 18 determines whether or not the optimum flight path _Ropt displayed on the display is approved based on the signal from the operation unit 13 (step S7). That is, in this step S7, the pilot confirms the optimum flight route _Ropt and various status information, approves if there is no problem, and denies if he wants to change.

If it is determined in step S7 that the optimal flight path _Ropt is not approved by the pilot (step S7; No), the control unit 18 shifts the process to the above-described step S5 and executes the flight path search process again. .
If it is determined in step S7 that the optimum flight route _Ropt has been approved by the pilot (step S7; Yes), the control unit 18 ends the attack content setting process.

  As described above, according to the present embodiment, for each of the plurality of grids M obtained by dividing the map data 155 in the horizontal plane, the score that quantifies “mission feasibility”, “accuracy”, and “survival” After P is calculated based on the map data 155, the attack position FP is set based on the points P of the plurality of grids M,. Thus, unlike the conventional case where the attack position is selected based on the experience and intuition of the pilot, the aptitude as the attack position FP of each point (lattice M) is set to “mission feasibility”, “accuracy” and “survivability”. The attack position FP can be set by quantitative evaluation in terms of “ Therefore, it is possible to calculate an appropriate attack position FP in the battle aircraft 10 without depending on the experience and intuition of the pilot.

  The embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

For example, in the above embodiment, the search for the optimum flight route R _opt from the mission start position FARP before the start of the mission has been described. However, after the mission is started (the original optimum flight route R _opt is in flight) The optimum flight route from the attack position FP to the attack position FP may be searched and updated at any time.

  Further, the range of the attack position calculation process by the attack position calculation program 151 and the flight path search process by the flight path search program 152 are not limited to those described above. For example, the attack position calculation process may include selection of the attack position FP based on the pilot's operation (step S4).
