[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared radiation target used for bombing training or shooting training of an infrared tracking type flying object, etc., and particularly has a relatively simple structure and reduces the influence of wind and sunlight. The present invention relates to an infrared radiation target that can make the temperature of infrared radiation substantially uniform and that consumes little power even when there is a temperature change due to wind speed fluctuations.

[0002]

2. Description of the Related Art For example, the following two types of conventional infrared radiation targets have been proposed. First, as described in Japanese Utility Model Laid-Open No. 63-23597, the first conventional example has a twin-hull type hull for mounting, and a large number of heat generating panels mounted on the hull and having a surface. And a mounted infrared radiating polyhedral dome. The heat generating panel is heated to a predetermined temperature by the operation of the infrared ray generating device stored therein, and infrared rays are radiated from the infrared ray radiating polyhedral dome upward, forward, backward, left and right. Thus, the projectile having the infrared homing device will track, for example, an infrared radiation target moving on the water, and the necessary bombing training or shooting training will be performed.

[0003] Next, as described in Japanese Utility Model Laid-Open No. 1-74496, a second conventional example is a twin-hull type hull for mounting, mounted on the hull and provided with heating means inside. And a dome-shaped infrared radiator on the surface of which an infrared transmitting film is stretched with an air layer interposed between the outer plate and the outer plate. Then, by the operation of the hot air supply device provided inside the above, the generated hot air makes a round of the dual structure flow path formed near the inside of the outer plate of the infrared radiator, thereby heating the above outer plate to a predetermined temperature. In addition, infrared rays are radiated from the dome-shaped infrared radiator in all directions upward, front, rear, left and right. As a result, necessary bombing training or shooting training is performed as in the first conventional example.

[0004]

However, in the infrared radiation target of the first conventional example described above, a large number of heat generating panels mounted on the surface of the infrared radiation polyhedral dome are exposed and come into direct contact with the outside air. Therefore, if the wind blowing around the dome is strong, the windward side of the dome is cooled by the wind and the temperature is lower than that of the leeward side, and the amount of infrared radiation from the heat generation panel in the vicinity is reduced. Therefore, the infrared rays radiated from the entire infrared radiating polyhedral dome become non-uniform. As described above, in order to maintain each heat generating panel at a predetermined temperature in response to the temperature change due to the wind speed fluctuation, large power is required. Conversely, the surface on which sunlight is directly incident has a higher temperature than the surface not exposed to sunlight, and the amount of infrared radiation from the heat generation panel in the vicinity is increased. Also in this case, there is a possibility that the infrared rays radiated from the entire dome become non-uniform.

In the infrared radiation target of the second conventional example, an infrared transmitting film is provided on the surface of a dome-shaped infrared radiation body so that the outer plate does not directly contact the outside air. Therefore, the change in the surface temperature due to the wind is suppressed, and the infrared radiation emitted at this time can be made substantially uniform. However, there is also a temperature difference between the surface on which sunlight is directly incident and the surface on which sunlight is not incident, and the infrared rays emitted at this time may be non-uniform. Further, a hot air supply device as heating means is provided inside the dome-shaped infrared radiator, and a dual structure hot air flow path is formed near the inside of the outer plate, so that the infrared radiator as a whole is The structure of the body was complicated. Therefore, it was expensive and the repair work after training use was troublesome.

Accordingly, the present invention addresses such a problem and has a relatively simple structure and can reduce the influence of wind and sunlight to make the temperature of infrared radiation substantially uniform. It is an object of the present invention to provide an infrared radiation target that consumes less power even when there is a temperature change due to wind speed fluctuations.

[0007]

In order to achieve the above object, an infrared radiation target according to the present invention includes a mounting base,
An infrared radiator that is mounted on the base and has a three-dimensional object having a large number of infrared radiation panels that individually emit infrared radiation on all or part of the outer surface thereof; and an infrared radiation panel of the infrared radiator. In an infrared radiation target having a power supply device for supplying electric power for operating the infrared radiation body and a temperature control means for controlling the temperature of the infrared radiation body, the individual infrared ray generation panels are formed of a plurality of strip-shaped pieces. Heating elements and reflectors are arranged alternately in the vertical direction with the longitudinal direction as the horizontal direction, and the adjacent heating elements and reflectors are intersected at an angle of 90 degrees or less in side view and are continuous zigzag shape In addition, a heat insulating material is interposed on the back side thereof, and an infrared transmitting film is stretched on the front side thereof.

Further, the infrared generating panel vertically mounted on the outer surface of the infrared radiator includes a heating element and a reflecting plate, which are adjacent to each other, and the heating element is inclined obliquely downward and upward.
It is effective to arrange the reflecting plate obliquely upward at the bottom.

[0009]

The infrared radiation target thus configured is mounted on the outer surface of the infrared radiation body in a large number, and the adjacent heating element and the reflection plate are crossed at an angle of 90 degrees or less in side view to form a continuous zigzag. Infrared rays are emitted to the surroundings by operating an infrared ray generating panel formed by interposing a heat insulating material on the back surface side and stretching an infrared ray transmitting film on the front side side. Thereby, the structure of the infrared radiator can be made relatively simple, and the temperature of the infrared radiation can be made substantially uniform by reducing the influence of wind and sunlight.

A large number of infrared generating panels 11, such as electric panel heaters, which individually emit infrared rays, are mounted on the outer peripheral side surface of the body. As shown in FIG. 4, the specific structure of the infrared radiator 2 is as follows: an H-shaped steel 12 and a T-shaped steel 13 are used to assemble a scaffold to form a cylindrical frame as a whole. As shown in FIG. 3, the infrared ray generating panels 11, 1
Are fitted and fixed with mounting brackets or the like. At this time, as shown in FIG. 5, the periphery of the cylindrical frame is divided into, for example, 24, and the infrared generating panels 11 may be applied one by one to the positions of the 24 divisions. Then, as shown in FIG. 3, by stacking, for example, five layers in the height direction of the infrared radiators 2, a total of 24 sheets × 5 =
120 infrared generating panels 11 are mounted.

A power supply device 3 provided inside the hulls 1a, 1b of the hull 1 supplies electric power for operating the infrared generating panels 11, 11,... Mounted on the outer peripheral side surface of the infrared radiator 2. And comprises, for example, a power generator.

They are arranged alternately in the vertical direction. And FIG.
As shown in (a), the adjacent heating elements 14 and the reflection plate 15 are joined in a continuous zigzag shape by intersecting at an angle within 90 degrees in a side view. Further, each of the heating elements 1
A heat insulating material 16 such as Styrofoam is interposed on the back surface side of the 4 and the reflecting plate 15 by filling or the like in order to prevent heat conduction from the heating element 14 or loss of heat due to convection, and Each heating element 14 and reflector 15
In order to prevent the heating element 14 from directly contacting the outside air and to prevent the temperature of the heating element 14 from fluctuating due to relative wind or increase heat loss due to convection, an infrared transmitting film such as polyethylene 17 are stretched. 6 and 7, reference numeral 18 denotes a rear plate for holding the heating element 14, the reflector 15, and the heat insulating material 16, and reference numeral 19 denotes the infrared transmitting film 1.
