BACKGROUND OF THE INVENTION
  The present invention provides support on the ground side when a helicopter makes a landing at a temporary take-off and landing field outside the airfield, mainly at night, during disaster rescue etc.apparatusIn particular, it is possible to support the landing at the temporary take-off and landing field by simultaneously indicating the approach direction and the landing approach angle of the helicopter by the flow and shape of the flashing light moving by the plurality of support lights that generate the flashing light.Helicopter for temporary landing supportSupport light andHelicopter temporary landingThe present invention relates to a support light device.
[0002]
[Prior art]
Conventionally, as a temporary landing support of a helicopter that is supported on the ground side when landing a helicopter on a temporary take-off and landing field outside the airfield at the time of disaster rescue etc. There is a helicopter temporary landing support method and a support light device used for the implementation.
[0003]
In this helicopter temporary landing support method, a plurality of support lights composed of flashlights are arranged at equal intervals on the boundary line of the 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 order of the support lights arranged on both sides from the front side of the approach direction to the back side at equal time intervals and simultaneously emitting light left and right, by generating a flash that moves along the approach direction of the helicopter The assistance light indicated the direction of approach 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 flashlights arranged at equal intervals on the boundary line of the landing zone, and among these support lights, the front side in the approach direction of the helicopter of the landing zone 1 is a master unit that repeatedly generates flash at a predetermined time interval, and the other support lights other than the master unit recognize the timing of generation of flash from the master unit and set the light emission order time set to itself. It was configured as a child that later flashed.
[0005]
[Problems to be solved by the invention]
However, in such a temporary landing support of the conventional helicopter, a plurality of support lights are arranged at equal intervals on the boundary line of the rectangular landing zone indicating the landing area. For example, if “three flashes” are repeated, at least six support lights are required in two rows, and if the approach axis is indicated, at least eight support lights are required. The number was relatively large. Moreover, even if a plurality of support lights are arranged on the boundary line of the landing zone, the landing approach angle to the landing area cannot be shown even though the landing area and the approach direction thereof can be shown. Therefore, the pilot must control the helicopter mounted instrument while controlling the helicopter so that the aircraft is held within a safe landing approach angle, and the driver's burden is particularly heavy at night. Alternatively, a dedicated navigation assistance device for indicating the landing approach angle may be required.
[0006]
In addition, as the support light device, both the main unit and the child unit are composed of flash lamps that repeatedly generate flash, so when the helicopter approaches the landing zone and immediately before landing, the flash of the flash lamp is dazzling to the pilot, There were times when it interfered with landing maneuvers. Furthermore, since the slave unit receives light or a radio 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 is Even if there was no problem, the slave unit stopped operating, and the entire support light device could not be used.
[0007]
  In view of this, the present invention addresses such a problem and temporarily indicates the approach direction and landing approach angle of the helicopter according to the flow and shape of the flashing light that moves by the plurality of support lights that generate the flashing light. Can support landing on take-off and landing fieldHelicopter for temporary landing supportSupport light andHelicopter temporary landingAn object is to provide a support light device.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
  FIG. 1 shows the present invention.RelatedHelicopter temporary landing supportThe lawFIG. 2 is an explanatory side view thereof. This helicopter temporary landing support method is to support the helicopter on the ground side mainly when landing at a temporary take-off and landing field outside the airfield during disaster rescue etc., and is designated as a temporary take-off and landing field as shown in FIG. A plurality of support lights L that generate flashing light around a landing point P at a predetermined location.₁, L₂, L₃, L₄Are arranged in an elongated polygonal shape with a long interval along the longitudinal direction of the axis C in the approach direction H of the helicopter and with a short interval in the orthogonal direction.
[0014]
Above support light L₁~ L_FourFor example, a flash lamp that repeatedly generates flash at a predetermined time interval may be used, or a lamp that generates strong light may be repeatedly turned on and off at predetermined time intervals. And support light L₁, L_FourAre arranged at long intervals along the longitudinal direction of the axis C in the approach direction H of the helicopter.₂, L_ThreeAre arranged at short intervals in the direction orthogonal to the axis C across the landing point P, and are arranged in an elongated polygon shape as a whole. For example, in the case of a vertically long diamond shape, the number of support lights is only four.
[0015]
Support lamp L arranged in the above-described elongated polygonal shape (for example, a vertically long rhombus shape or an oval shape).₁~ L_FourWhen the helicopter enters at a predetermined landing approach angle θ as shown in FIG.₁~ L_FourAre arranged in such a ratio that they appear to form a regular polygonal shape (for example, a rhombus shape in which a square is inclined 45 degrees or a perfect circle). Now, in FIG. 3, the support light L placed on the ground surface G along the longitudinal direction of the axis C in the approach direction H of the helicopter.₁, L_FourA support light L placed on the ground surface G in a direction orthogonal to the axis C, where A is the actual spacing of₂, L_ThreeLet B be the actual interval. On the other hand, in FIG. 4, the support light L that can be seen by the helicopter operator entering at the landing approach angle θ.₁, L_FourThe apparent interval of a is a and the support light L₂, L_ThreeLet b be the apparent interval.
[0016]
In this state, in FIG. 4, when viewed from the helicopter approach direction H, the support light L₂, L_ThreeThe actual interval B and the apparent interval b are equal, and b = B. In addition, support light L₁, L_FourThe relationship between the actual interval A and the apparent interval a is represented by the triangle L shown in FIG.₁L_FourIn M, a = Asinθ. On the other hand, the support light L that can be seen by the pilot of the helicopter entering at the landing approach angle θ₁~ L_FourIn order for the apparent polygonal shape to be, for example, a rhombus shape or a perfect circle formed by inclining a square by 45 degrees, a = b must be satisfied.
[0017]
To summarize the above relationship:
a = Asinθ (1)
b = B (2)

When entering at an altitude higher than the line of the landing approach angle θ, it appears to be deformed into a vertically long polygonal shape as shown in FIG. 6A, and at an altitude lower than the line of the landing approach angle θ. When entering, it appears to be deformed into a horizontally long polygonal shape as shown in FIG. Therefore, the plurality of support lights L₁~ L_FourThe predetermined landing approach angle θ of the helicopter can be shown to the operator by the appearance of the elongated polygonal shape formed in (1).
