Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is an infrared light beam used for bombing training or target shooting training such as infrared tracking flying objects. Regarding radiation emitting targets, they are particularly easy to construct and are less affected by wind and sunlight. By eliminating this, the temperature of infrared radiation can be made almost uniform, and the temperature due to wind speed fluctuations can be made almost uniform. This invention relates to an infrared emitting target that consumes little power even under changes.

[Conventional technology]

For example, the following two targets have been proposed as conventional infrared radiation targets of this type: There is. First, the first conventional example is as described in Japanese Utility Model Application Publication No. 63-23597, A twin-hulled hull for mounting and a heat generating panel mounted on the hull. It consisted of a large number of infrared emitting polyhedral domes attached. And within the above The heating panel is heated to a predetermined temperature by the operation of an infrared generator stored in the unit. The infrared rays are emitted from the infrared emitting polyhedral dome in all directions upward, forward, backward, left and right. was beginning to be emitted. This allows aircraft with infrared homing devices to The flying object will track an infrared emitting target moving over water, for example, and deliver the required explosive Shooting training or target practice will be conducted.

0003 Next, the second conventional example is as described in Utility Model Application Publication No. 1-74496. A twin-hulled hull for use in the It has a wind supply device and an infrared transparent film is stretched on the surface with an air layer between it and the outer panel. It consisted of a dome-shaped infrared radiator. And installed inside the above Due to the operation of the hot air supply device, the generated hot air is distributed near the inside of the outer panel of the infrared radiator. The outer plate is heated to a predetermined temperature by going around the double-structured flow path formed in the Infrared rays are emitted from the above dome-shaped infrared radiator in all directions upward, forward, backward, left and right. It was starting to get shot. As a result, similar to the first conventional example, the required bombing training Drill or target practice will be held.

[Problem that the idea aims to solve]

However, in the first conventional infrared emitting target mentioned above, the infrared emitting polyhedron Many heat-generating panels attached to the surface of the room are exposed and in direct contact with the outside air. Therefore, if there is a strong wind blowing in the surrounding area, the windward side of the dome will be affected by the wind. The temperature is lower than that on the leeward side, and infrared radiation from nearby heating panels The amount will decrease. Therefore, the radiation is emitted from the entire infrared emitting polyhedral dome. The infrared rays emitted were non-uniform. In this way, the temperature due to the above wind speed fluctuation A large amount of power is required to maintain each heating panel at a predetermined temperature despite changes. It was something. Conversely, the surface on which the sun's rays directly enter is the one where the sun's rays do not hit The temperature will be higher than that of the other side, and the amount of infrared radiation from the heat generating panel in the vicinity will increase. That's what happens. In this case as well, the infrared rays emitted from the entire dome become non-uniform. There was a risk.

[0005] In addition, in the second conventional example of infrared radiation target mentioned above, the infrared radiation target has a dome shape. An infrared-transparent membrane is placed on the surface of the body to prevent the outer skin from coming into direct contact with the outside air. This suppresses changes in surface temperature caused by wind, and the infrared rays emitted at this time can be substantially uniform. However, the surface on which the sun's rays directly enter and the surface on which it does not enter There will also be a temperature difference between the surface and the surface, and the infrared rays emitted at this time will be non-uniform. There was a risk. Furthermore, inside the dome-shaped infrared radiator, there is a A hot air supply device is installed, and a double-walled hot air flow path is installed near the inside of the outer panel. was formed, and the overall structure of the infrared radiator was complex. Therefore, high In addition to being expensive, repair work after training use was troublesome.

[0006] Therefore, the present invention addresses these problems and has a relatively simple structure. The temperature of infrared radiation can be made almost uniform by reducing the influence of wind and sunlight. , and provides an infrared radiation target that consumes less power even when temperature changes due to wind speed fluctuations. The purpose is to provide

[0007]

[Means to solve the problem] In order to achieve the above purpose, the infrared radiation target according to the present invention has a mounting base and , is mounted on this base, and all or part of the outer surface individually emits infrared rays. This is an infrared radiator consisting of a three-dimensional object equipped with a large number of infrared ray generating panels. A power supply device that provides power to operate the infrared generating panel of the infrared emitter of and temperature control means for controlling the temperature of the infrared radiator. In the above, each infrared generating panel has a plurality of heating elements formed in a rectangular shape. and reflectors are arranged alternately in the vertical direction with their longitudinal direction as the horizontal direction, and are arranged next to each other. A continuous zigza where the heating element and the reflecting plate intersect at an angle of less than 90 degrees when viewed from the side. Insulating material is interposed on the back side, and red on the front side. It is made of a film that transmits external radiation.

[0008] In addition, the infrared generation panel installed vertically on the outer surface of the above infrared radiator is , the heating element is reflected upward and diagonally downward between the heating element and the reflecting plate that are adjacent to each other. It is effective to place the board diagonally upward at the bottom.

[0009]

[Effect]

A large number of infrared radiation targets configured in this way are attached to the outer surface of the infrared radiator. The heating element and the reflecting plate that are adjacent to each other are connected so that they intersect at an angle of less than 90 degrees when viewed from the side. They are joined in a zigzag shape, and a heat insulating material is interposed on the back side. Activates an infrared generation panel formed by pasting an infrared transmission film on the front side. As a result, it emits infrared rays to the surrounding area. This changes the structure of the infrared emitter above. In addition to being relatively simple, it is possible to reduce the temperature of infrared radiation by reducing the influence of wind and sunlight. It can be made substantially uniform.

Temperature control device 4, command receiver 7, electric control panel 8, engine 9, main tank 10 It is equipped with such things as

0012 An infrared radiator 2 is provided on the upper surface of the deck 5 of the hull 1. this infrared The radiation emitter 2 is a target used for bombing training or shooting training such as an infrared tracking type flying object. It emits infrared rays to the surrounding area, and its overall shape is, for example, about 9 meters in diameter. It is formed into a cylindrical body with a height of about 6 m, and on its outer circumferential side there are individual electric currents that emit infrared rays. A large number of infrared generating panels 11, 11, . . . such as air panel heaters are installed. The specific structure of the infrared radiator 2 is as shown in FIG. The tower is constructed using Steel 13, forming a cylindrical frame as a whole, and the outer circumference of the tower is As shown in Fig. 3, one infrared generating panel is placed between adjacent T-beams 13, The screws 11, 11, . . . are fitted and fixed with mounting brackets or the like. At this time, Figure 5 As shown in the figure, divide the circumference of the cylindrical frame into 24 parts, and place the parts at the positions of the 24 parts. It is sufficient to apply the infrared ray generating panels 11 one by one. And as shown in Figure 3 By stacking the infrared radiators 2 in, for example, five stages in the height direction, In total, 24 x 5 = 120 infrared generating panels 11 are installed.

[0013] The power supply device 3 provided inside the bodies 1a and 1b of the hull 1 is configured to emit infrared rays. In order to operate the infrared generation panels 11, 11, ... attached to the outer peripheral side of the projectile 2. A device that supplies electrical power to the engine, such as a motor generator. Also, the above body A temperature control device 4 provided inside 1a and 1b controls the temperature of the infrared radiator 2. from a temperature sensor 20 provided on the infrared generation panel 11, which will be described later. The temperature is controlled to a predetermined temperature by inputting a detection signal.

[0014] Here, in the present invention, each infrared generating panel 1 of the infrared radiator 2 is 1 is formed as shown in FIGS. 6 and 7. That is, as shown in Figure 6 , an electric panel heater that is formed into strips with the same predetermined width and emits infrared rays. A plurality of heating elements 14 such as A plurality of reflective plates 15 such as aluminum plates that reflect infrared rays emitted from the heating element 14 and the longitudinal direction of these plates is aligned with the lateral direction of the infrared generating panel 11. They are also arranged alternately in the vertical direction. Then, as shown in Figure 7(a) , the heating element 14 and the reflecting plate 15 that are adjacent to each other intersect at an angle of less than 90 degrees when viewed from the side. They are joined in a continuous zigzag pattern. Furthermore, each of the heating elements 14 and a reflecting plate On the back side of 15, heat is transferred backward from the heating element 14 or heat is transferred by convection. Insulating material 16 such as styrofoam is interposed by filling etc. to prevent loss. The heating element 14 is located on the surface side of each heating element 14 and the reflecting plate 15. It prevents direct contact with the outside air and prevents the temperature of the heating element 14 from fluctuating due to relative wind. Or, to suppress the increase in heat loss due to convection, use infrared transparent materials such as polyethylene. A film 17 is applied. In addition, in FIGS. 6 and 7, the reference numeral 18 is the same as above. The rear plate for holding the heating element 14, the reflecting plate 15, and the heat insulating material 16 is shown. No. 19 indicates a side end plate that fastens the four sides of the above-mentioned infrared transmitting film 17. 20 indicates a temperature sensor that measures the temperature of the heating element 14.

[0015] Due to the structure of the infrared ray generating panel 11, the infrared ray generating panel 11 The emitted infrared rays are directed directly from the heating element 14 as shown by arrow B in FIG. 7(a). The tangentially propagating one and the one generated by the heating element 14 as shown by arrow C are reflected on the reflector plate. 15 and is reflected forward, and is emitted to the front of the panel. The directivity of the emitted infrared rays 21 becomes high. Further, the heating element 14 and the reflecting plate 15 By joining them in a zigzag shape, the area of the heating element 14 can be reduced. Therefore, it is economical and can suppress heat loss.

[0016] Furthermore, in the structure of the infrared ray generating panel 11, the cylindrical infrared ray For those mounted vertically on the outer peripheral side of the projectile 2, as shown in Fig. 7(a). The heating element 14 is positioned above and diagonally downward, and the reflective plate 15 is positioned below it. They are placed diagonally upward on both sides and joined alternately in a zigzag pattern. This kind of structure For example, by making the structure If there is, this solar ray will not be able to enter the plate surface of the heating element 14 located above. For example, if the light is incident only on the reflecting plate 15 located below, the angle follows the law of reflection. It is reflected in the direction of arrow F. Therefore, the above sunlight is not absorbed at all by the heating element 14. The temperature of the heating element 14 is prevented from rising, and the temperature fluctuation of the infrared radiating element 2 is prevented. can be prevented.

[0017] In addition, in FIGS. 1 to 3, reference numeral 22 indicates a wireless communication target for this infrared radiation target from the outside. 23 indicates an antenna for transmitting and receiving commands for control by radio communication. or radar countermeasures for target training aircraft to detect this infrared emitting target with radar. This shows the irradiation device.

[0018] Figure 8 shows the temperature control of the infrared emitter 2 of the infrared radiation target configured as described above. FIG. This control system sends and receives commands as shown in the figure. The reliable antenna 22, the command receiver 7, the electric control panel 8, the power supply device 3, and the temperature control It consists of a control device 4, an infrared radiator 2, and a temperature sensor 20, and each of the above devices includes: Installed in each compartment partitioned by bulkheads 6, 6, ... in the hull 1 shown in Figure 1. It is being Then, for example, from an aircraft participating in training, the command transmission/reception antenna 22 Receives the command radio wave, inputs it to the command receiver 7, takes out the command signal, and increases the number of command signals. It is sent to an electric control panel 8, for example, an electric control panel consisting of a CPU (central processing unit). 8 decodes the command and sends a control signal to the power supply device 3 and temperature control device 4.

[0019] Then, the power supply device 3 operates and supplies power to the infrared generation panel 11 of the infrared radiator 2. At the same time, the temperature control device 4 operates. With the above power supply, infrared The heating element 14 of the ray generating panel 11 is heated and emits infrared rays. The temperature of the heating element 14 is detected by the temperature sensor 20, and the detection signal is sent to the temperature controller 20. The data is sent to the control device 4. A target temperature is set in this temperature control device 4, and the above-mentioned Compare the detected temperature to extract the error and provide feedback to eliminate this error. Control. Thereby, the temperature of the infrared radiator 2 is controlled to be substantially constant. this As a result, substantially uniform infrared rays are emitted from the infrared radiator 2 shown in FIG. The infrared sensing device detects the projectile more accurately and the infrared emitting target locates the projectile. The desired bombing or shooting training will take place.

[0020] In addition, in FIGS. 1 to 3, the infrared radiator 2 is formed in a cylindrical shape and has a red Although the external line generating panels 11, 11, ... are shown as being attached only to the outer peripheral side, The present invention is not limited to this, and the infrared ray generating pad is placed on the roof top surface of the cylindrical infrared radiator 2. The flannel 11 may be arranged and attached in a plane. Furthermore, the shape of the infrared radiator 2 is , it is not limited to a cylindrical shape, it may be a dome shape with a hemispherical upper part, The whole may be formed into a spherical shape. Furthermore, the base on which the infrared radiator 2 is mounted is The hull 1 is not limited to floating on water, but may be a cart placed on land. Also, its basis The stand may be a self-propelled type or a stationary type.

The heating element 14 and the reflecting plate 15 that are adjacent to each other intersect at an angle of less than 90 degrees when viewed from the side. They are joined in a continuous zigzag shape, and a heat insulating material 16 is interposed between them on the back side. The infrared ray generating pattern is formed by placing an infrared ray transmitting film 17 on the surface of By operating the channel 11, infrared rays can be emitted to the surroundings. this Therefore, if the structure of the infrared radiator 2 is simplified compared to the first and second conventional examples, In addition, it is possible to reduce the influence of wind and sunlight and make the temperature of infrared radiation almost uniform. power consumption can be reduced even when there are temperature changes due to wind speed fluctuations. and , the infrared rays emitted from the infrared radiator 2 can be made substantially uniform; The radiation emitter 2 performs desired bombing training or shooting training for the flying object.
