SU8268A1 - Device for automatic installation of landing signs at the aerodrome - Google Patents

Description

The present invention relates to the equipping of an aerodrome with light signaling devices using light wells with searchlights and electric lamps turned on and off automatically according to the movement of the wind vane, and is intended to indicate the force and direction of the wind to the pilot.

In FIG. 1 shows the wiring diagram of the lamps and their power supply; FIG. 2 is a vertical section of a tower with a device for indicating the direction and strength of the wind; FIG. 3-part fixture to turn on the lamp.

The group of lamps m (Fig. 1) forming a star (or some other figure) is powered by wires 7 from a current source 8. Inside this figure is a five-pointed star made up of lamps of lesser power arranged along five straight lines line m iv. Each such lamp line (star link) is powered by the same current source 8 independently, and two links are simultaneously lit, forming a star beam facing in the direction opposite to the direction of the wind and the point

with his own indicating direction in which the pilot should land. Landing can be done within the angle formed by these links. An inner five-pointed star indicating five directions for landing may have a number of rays and more than five, to more accurately indicate the direction of the wind. Inside the circuit formed by the lamps 6, there are five powerful lamps 1-5 that are independently powered by the current source 8 and can be ignited either as one, or two, three, four or five, depending on the strength of the wind, and perform alarms according to the clock system. A spotlight 9 is located in the center, sending a bundle of red rays upward and fed directly from the current source 8 by means of wires 10 connected to the highway 11.

FIG. 2 shows a tower 12 in section, through which the cover passes a shaft 24 rotating on a bolster 23, carrying a crossbar 25 at the top, provided at one end with a surface 26 playing the role of a wind vane, and at the other end a counterweight 27

and surface 28 hanging vertically. When the vane 26 rotates, depending on the direction of the wind, the shaft 24, which passes through the lid of the table 29, on which the contact arcs 30 are isolated, rotates respectively. The sliding or rotating contacts 31, 32, 33 and 34 contact the arcs. insulated from each other and mounted on a common crossmember 35, which is attached to the shaft 24 parallel to the crossbar 25 (Fig. 3). When the shaft 24 is rotated, these four contacts will come into contact with the contact arcs 30 located on the four circles, respectively indicated by the four sliding (or rotating) contacts. There are five arcs along each circle, corresponding to the number of rays of the inner five-pointed star (Fig. 1). Contacts 31-34 are connected to trunk 11 in parallel by wires 36 and 37 (Fig. 3), at which the highway is inserted inside shaft 24 through brushes 38 and rings 39. Contact arcs are located in five sectors of a circle, between which small gaps filled with non-conductive substance. Each pair of adjacent arcs of the same sector is connected to the wires that feed the corresponding link of the inner star, because the arrangement of the sectors corresponds to the arrangement of the rays of the inner star (for example, the beam composed of links II and IY corresponds to the lower sector similar to that in the drawing and so on, but in order) - with a certain wind direction, the wind vane will set the crossmember 35 over a certain sector, for example over the bottom one, and the current from highway 11 through wires 36 and 37, pins 31 and 32, 33 and 34, along arcs of this sector , through wires 60 and 61, 62 will go to links II and IT, which will be connected in parallel (Fig. 1). The lamps of these links will light up and indicate the direction of landing of the airplane. Similarly, when, under the influence of the wind that changed its direction, the wind vane installs crossmember 35 over its left sector, the lamps of links III and I will be lit, while

the previously burning ones will go out before the new direction is indicated for launching airplanes on the parade ground of the airfield.

An indication to the pilots of the wind force waiting for them during the descent is also automatically given by means of a board 28 tightly mounted on an axis 40 rotating in the openings of the walls of the box 41 attached to the crossbar 25 (Figs. 1 and 2). Inside the box are tightly mounted cylinders 42, 43, 44, 45 and 46 of the insulator, mounted on the same axis 40, on the surface of which metal plates 42, 43 44 45 and 46 are attached, all five cylinders with nlastinki-according to the number of points wind strength is estimated. The points are expressed in the ANGULAR angular deviation of the plate 28 from the vertical, with the lowest score corresponding to the lowest wind force when the plate 28 is bent at the right angle, i.e. at an angle of up to 18 °, the highest score corresponds to the maximum deviation of the plate, up to 90 °. Accordingly, the plates on the cylinders 42-46, starting from one straight line parallel to the axis 40, terminate farther and farther from this straight line, with the first plate covering the first cylinder 90 °, the second covering 90 ° -18 ° i.e. at 72, and so on; the last plate covers the fifth cylinder only on 18. Inside the same box 41 there is a fixed strip 47, to which brushes or rotating contacts 42 43, 44, 45 are isolated. A pair of such contacts corresponds to each cylinder. Their points of contact with the cylinders are located on one straight line passing, in the vertical position of the plate 28, through the edge of the plate 42, protruding farther than the others. Cylinders 42-46 correspond to cylinders 48, 49, 50, 51 and 52 of the insulator, with a pair of metal rings on each; These cylinders are tightly mounted on the shaft 24 (Fig. 1 and 2) and each of them corresponds to a pair of brushes applied to the rings. These brushes 48, 49, 50, 51 and 52 are attached in isolation to the strap 53, fixedly attached to the casing of the tower 12, and serve to divert current from the main 11,

extending inside the shaft, to incandescent lamps 1, 2, 3, 4 and 5. which are connected to this line by wires in parallel, through their worn contacts and plates on the cylinders inside the box 41, and through the said rings and brushes On shaft 24, as echoed in FIG. 1. Thus, when the plate 28 deviates from the vertical at angles up to 18 °, only one lamp 1 will be switched on, since only one pair of contacts 42 will be electrically connected by means of a plate 424. If the plate 28 is deflected at an angle up to 36 °, two lamps 1 and 2, because plate 42 will still keep lamp 1 under current, plate 43 will turn on the second lamp, etc. When plate 28 deflects by 90 °, all five lamps will be lit, indicating to the pilot the maximum wind strength is five points. Lamps 1, 2, 3, 4 and 5 emit red light so that you can immediately distinguish them from other light signals.
