[Conventional technology]

Conventionally, as a helicopter's temporary landing support that is provided on the ground side when a helicopter makes a landing on a temporary takeoff and landing site outside the airfield mainly at night during disaster relief, Japanese Patent Application Laid-Open No. 9-150799 relating to the application of the present applicant. There are helicopter temporary landing support methods and support lighting devices used to implement them, as described in.

【0003】

In this helicopter temporary landing support method, a plurality of support lights consisting of flash lights are arranged at equal intervals on the boundary line of a rectangular landing zone indicating the landing area of the helicopter, and along the approach direction of the helicopter in the landing zone. By repeating the ordering of the support lights arranged on both sides from the front side to the back side in the approach direction at equal time intervals and emitting light at the same time on the left and right, a flash of light moving along the approach direction of the helicopter is generated. , The above support light was designed to indicate the approach direction and the boundary of the landing zone at the same time.

【0004】

Further, the support light device has a plurality of support lights composed of flash lights arranged at equal intervals on the boundary line of the landing zone, and among these support lights, the front side of the helicopter in the landing zone in the approach direction. The one located in is a master unit that repeatedly generates flashes at predetermined time intervals, and the other support lights other than this master unit recognize the generation timing of the flash from the master unit and set the light emission turn time by themselves. It was configured as a child device that later generated a flash of light.

【0005】

[Problems to be Solved by the Invention]

However, in such a conventional helicopter temporary landing support, since a plurality of support lights are arranged at equal intervals on the boundary line of the rectangular landing zone indicating the landing area, the distinctiveness of the flash of the support lights For example, if you repeat "3 flashes" to improve the condition, you need at least 6 support lights in 2 rows, and if you want to show the approach axis, you need at least 8 support lights in total. The number was relatively large. In addition, by simply arranging a plurality of support lights on the boundary line of the landing zone, the landing area and its approach direction could be shown, but the landing approach angle to the landing area could not be shown. Therefore, the operator had to operate the helicopter so as to hold the aircraft within a safe landing approach angle while checking the onboard instruments of the helicopter, which would increase the burden on the operator, especially at night. Alternatively, a dedicated navigation aid may be required to indicate the landing approach angle.

【0006】

In addition, as a support light device, both the parent device and the child device consist of flash lamps that repeatedly generate flashes, so when the helicopter approaches the landing zone and is about to land, the flashes of the flash lamps are dazzling to the operator, and on the contrary. It sometimes interfered with landing maneuvers. Furthermore, since the slave unit receives light or wireless signal from the master unit and generates a flash at a predetermined timing, if the master unit fails and does not operate, the function of the slave unit itself will be changed. Even if there was no problem, the slave unit would not work, and the entire support light device could become unusable.

【0007】

Therefore, the present invention addresses such a problem and indicates the approach direction and the landing approach angle of the helicopter at the same time by the flow and shape of the moving blinking light of the plurality of support lights that generate the blinking light. It is an object of the present invention to provide a helicopter temporary landing support method capable of supporting landing at a landing site, and a support light and a support light device used for the implementation thereof.

【0008】

[Means for solving problems]

In order to achieve the above object, the helicopter temporary landing support method according to the present invention provides a plurality of support lights that generate blinking lights around the landing point of the helicopter's temporary landing site before and after the axis of the helicopter's approach direction. It is arranged in an elongated polygonal shape with a long interval along the direction and a short interval in the orthogonal direction, and the aspect ratio of the arrangement shape is such that when the helicopter approaches at a predetermined landing approach angle, the above-mentioned multiple support lights The helicopter is arranged in a ratio so that it looks like a regular polygon, and the above multiple support lights are repeatedly blinked in order from the front side to the back side in the approach direction of the helicopter at predetermined time intervals. The moving flashing light flow and shape of the support light simultaneously indicate the approach direction and landing approach angle of the helicopter to support landing at the temporary takeoff and landing site.

【0009】

The support lights for temporary helicopter landing support include a flash lamp that repeatedly generates flashes at predetermined time intervals, a continuous light lamp that generates continuous light that is dimmed from the light intensity of the flash lamp, and the flash lamp. A receiver that receives the radio signal of the light emission control of the continuous light lamp, a light emission order switching means for switching the light emission timing of the flash lamp based on the light emission control signal from the receiver, and a light emission control signal from the receiver. It includes a light emitting unit switching means for switching light emission between the flash lamp and the continuous light lamp, and a battery for supplying power to each of the above components.

【0010】

Then, a brightness switching means for switching the brightness of the light emitted from the continuous light lamp in a plurality of stages may be added.

【0011】

Further, the helicopter temporary landing support light device includes a flash lamp that repeatedly generates flashes at predetermined time intervals, a continuous light lamp that generates continuous light that is dimmed from the light intensity of the flash lamp, and the flash lamp and continuous light. The above is based on a receiver that receives a radio signal for controlling the light emission of an optical lamp, a light emission order switching means for switching the light emission timing of the flash lamp based on a light emission control signal from the receiver, and a light emission control signal from the receiver. Around the landing point of the temporary takeoff and landing site of the helicopter, a plurality of support lights including a light emitting unit switching means for switching the light emission between the flash lamp and the continuous light lamp and a battery for supplying power to each of the above components are provided. In addition, the helicopter is arranged in an elongated polygonal shape with a long interval along the anteroposterior direction of the approach direction axis of the helicopter and a short interval in the orthogonal direction, and the aspect ratio of the arrangement shape is the landing approach angle specified by the helicopter. When entering with, the ratio is arranged so that the plurality of support lamps appear to form a regular polygonal shape, and the radio signals for controlling the light emission of the flash lamp and the continuous light lamp are transmitted to the plurality of support lamps. It is equipped with a transmitter to transmit, and the light emission control signal from this transmitter causes the plurality of support lights to blink in order from the front side to the back side in the approach direction of the helicopter at predetermined time intervals. By repeating the above steps and the flow and shape of the blinking light that the support light moves, the approach direction and the landing approach angle of the helicopter are simultaneously indicated to support the landing at the temporary takeoff and landing site.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan explanatory view showing an embodiment of the helicopter temporary landing support method according to the present invention, and FIG. 2 is a side explanatory view thereof. This helicopter temporary landing support method assists the helicopter on the ground side when landing at a temporary landing site outside the airfield mainly at night during disaster relief, etc., and is designated as a temporary landing site as shown in Fig. 1. A plurality of support lights L that generate blinking light around the landing point P at a predetermined location₁, L₂, L₃, L₄Are arranged in an elongated polygonal shape with a long interval along the anteroposterior direction of the axis C of the helicopter's approach direction H and a short interval in the orthogonal direction.

【0014】

Above support light L₁~ L₄For example, a flash lamp that repeatedly generates a flash at a predetermined time interval may be used, or a lamp that generates a strong light may be repeatedly turned on and off at a predetermined time interval. And support light L₁, L₄Are placed at long intervals along the anteroposterior direction of the axis C of the helicopter's approach direction H, and the support light L₂, L₃Are arranged at short intervals in the direction orthogonal to the axis C with the landing point P in between, and are arranged in an elongated polygonal shape as a whole. For example, in the case of a vertically long rhombus, only four support lights are required.

【0015】

Support lamp L arranged in the above elongated polygonal shape (for example, vertically long rhombus or ellipse)₁~ L₄When the helicopter approaches at a predetermined landing approach angle θ as shown in FIG. 2, the aspect ratio of the arrangement shape is as follows.₁~ L₄The ratio is arranged so that the squares appear to form a regular polygonal shape (for example, a rhombus shape in which a square is tilted 45 degrees or a perfect circle). Now, in FIG. 3, the support light L placed on the ground surface G along the front-rear direction of the axis C of the helicopter's approach direction H.₁, L₄Let A be the actual distance between the two, and the support light L placed on the ground surface G in the direction orthogonal to the above axis C.₂, L₃Let B be the actual interval between. On the other hand, in FIG. 4, the support light L seen by the helicopter operator approaching at the landing approach angle θ₁, L₄Let a be the apparent interval of, and support light L₂, L₃Let b be the apparent interval of.

【0016】

In such a state, in FIG. 4, when viewed from the helicopter approach direction H, the support light L₂, L₃The actual spacing B and the apparent spacing b are equal, and b = B. Also, support light L₁, L₄The relationship between the actual spacing A and the apparent spacing a is the triangle L shown in FIG.₁L₄At M, a = Asinθ. On the other hand, the support light L seen by the helicopter operator approaching at the landing approach angle θ₁~ L₄In order for the apparent polygonal shape of to be, for example, a rhombus or a perfect circle with a square tilted 45 degrees, a = b must be satisfied.

【0017】

To summarize the above relationships, a = Asinθ ... (1) b = B ... (2) a = b ... (3) So from these formulas Asin θ = B ... (4) Will be. Therefore, support light L₁~ L₄Aspect ratio A / B of the arrangement shape of A / B = 1 / sinθ ... (5) Will be.

【0018】

That is, a plurality of support lights L₁~ L₄Is arranged in an elongated polygonal shape around the landing point P, and the aspect ratio A / B of the arrangement shape is arranged so as to satisfy the above equation (5), the helicopter approaches at a predetermined landing approach angle θ. When doing, the above multiple support lights L₁~ L₄Becomes visible in a regular polygonal shape. The relationship between the landing approach angle θ obtained by the above equation (5) and the aspect ratio A / B of the elongated polygonal shape is shown in the table shown in FIG. For example, when the landing approach angle θ is 6 degrees, the aspect ratio A / B of the elongated polygon is 9.6, and when the landing approach angle θ is 10 degrees, the aspect ratio A / B of the elongated polygon is 5.8.

【0019】

And the above-mentioned plurality of support lights L₁~ L₄When is arranged in such an elongated polygonal shape, the helicopter operator approaching in the approach direction H shown in FIG.₁~ L₄The polygonal shape formed by is a regular polygonal shape (in this case, a square or a perfect circle tilted by 45 degrees, etc.) as shown in Fig. 6 (b) when approaching on the line of the predetermined landing approach angle θ. When approaching at an altitude higher than the line of the landing approach angle θ, it looks deformed into a vertically long polygonal shape as shown in Fig. 6 (a), and at an altitude lower than the line of the landing approach angle θ. When entering, it appears to be transformed into a horizontally long polygonal shape as shown in Fig. 6 (c). Therefore, the above-mentioned plurality of support lights L₁~ L₄The appearance of the elongated polygonal shape formed by can indicate to the operator a predetermined landing approach angle θ of the helicopter.

【0020】

Multiple support lights L arranged in an elongated polygonal shape as described above₁~ L₄Repeats blinking in order from the front side to the back side of the helicopter's approach direction H at predetermined time intervals. That is, in FIG. 7, first, as shown in (a), the first support light L located on the front side.₁Flashes, then the second and third support lights L located in the middle as shown in (b)₂, L₃Flashes at the same time, and then the fourth support light L located on the back side as shown in (c)₄Flashes and then pauses for a certain period of time.

【0021】

When this is shown over time, as shown in Fig. 7 (d), the first support light L₁Flashes, then time t₁After (eg 0.25 seconds) the second and third support lights L₂, L₃Flashes at the same time, then time t₂After (for example, 0.25 seconds) the fourth support light L₄Flashes, then time t₃Pause for (for example, 1.5 seconds), then support light L again₁ L₂, L₃ L₄The above blinking is repeated in the order of. This support light L₁ L₂, L₃ L₄By blinking three times in the order of, the helicopter operator can see the flow of blinking light moving as shown by arrows D and E, and this flow of blinking light indicates the approach direction H of the helicopter to the operator. Can be done.
