Description

The invention relates to aviation communications.

Known devices for transmitting data [1, 2, 3, 4, 5], in which it is proposed to use stationary, mobile and floating (airborne, including freely drifting) platforms for placing radio communication equipment. However, all known devices for organizing radio links [1, 2, 3, 4, 5] do not provide the necessary speed of deployment of the radio link, the stability of its operation and mobility. The known repeater design, including a balloon and an active repeater unit suspended under it to implement a method for organizing a radio link [4], does not provide a radio link longer than the flight time of the aircraft, since the carrier - a balloon - drifts under the influence of air masses and for a short time, it can go at ranges at which communication becomes impossible. A freely drifting balloon poses a safety risk to aircraft flying. The known method of organizing a radio communication line using a set of airborne platforms launched from the ground [5] also does not provide acceptable operational indicators, since it has:

- the high complexity of the simultaneous control of all air platforms included in the communication system, in the conditions of uncertainty and unpredictability of their movement parameters;

- high cost of the system;

- high danger to air transport;

- low guarantee of stable radio communications for a given time.

Known devices for organizing communication radio lines using communication repeaters [2] use stationary or mobile towers (towers), on top of which radio equipment is located. The use of stationary or mobile towers (towers) significantly reduces the possibility of creating new and temporary radio communication lines in sparsely populated and inaccessible areas, and requires significant investment for operation.

The objective of the invention is the development of an autonomous transponder discharged from an aircraft for organizing a radio link that would achieve the following technical result: to ensure transportation of the transponder on the aircraft's external sling, discharge from any aircraft, automatically securing the transponder to the earth's surface and reliable transmission of radio signals during set time for any distance on any part of the earth’s surface with minimal time costs and and vehicles.

The essence of the invention is a resettable stand-alone radio signal repeater, comprising a housing, an active repeater unit, a mooring rope and a balloon with a cylinder for compressed gas. The hull includes a head, center and aft. The said body is made in the form of a body of revolution. A mooring device is located in the head of the hull. On the central part of the body are installed yokes for suspension on the beam holder and at least two drop-down braking surfaces. Each mentioned braking surface is attached to the central part on a hinge. All these braking surfaces are connected to each other by means of a mechanical synchronizer connected to the surfaces using movable profiled struts. A mooring halyard is laid inside the hull, which is attached at one end to the mooring device in the head, and through the swivel with the other end is connected to the hull of the active repeater unit. The active repeater unit is attached to the aft and in the transport position enters the body as if in a pencil case. The aft part has a shell, which is formed by four rotary sections. Inside the said shell there is a compartment for placing the balloon in the folded state and a cylinder for storing compressed gas, while the end surface of the rear compartment is made in the form of an easily destroyed membrane. The aft part is connected to the said central part by means of locks.

The resettable stand-alone radio signal repeater has a housing which is made in the form of a body of revolution. The hull consists of three parts (Fig. 1): head 1, central 2 and aft 3. On the central part of the hull, yokes 4 are installed on top, allowing the repeater to be hung on the beam holder of the aircraft. At least two deflectable braking surfaces are installed on the central part 2 of the hull 5. A mooring device 8 is placed in the head part 1 of the hull 8 (Fig. 2). Using this mooring device, the repeater is fixed to the earth's surface after being dumped from the aircraft. The aft part 3 is a shell formed by four deflectable sections 6 (FIG. 3), inside which there is a compartment with a balloon 7 (FIG. 4) when folded and a compressed gas cylinder. From the end, the stern shell is closed by an easily destructible membrane. The active unit of the repeater 9 is attached to the aft 3 (figure 1) and in the transport position enters the Central part of the housing 2 as a pencil case. Each braking surface 5 is attached to the central part of the housing 2 on a hinge. In order to synchronize the opening, all braking surfaces 5 (Fig. 4) are connected to each other by means of a mechanical synchronizer 12 through profiled struts 11. Inside the central part of the housing 2 (Fig. 1), a mooring rope 10 (Fig. 4) is laid, which is attached at one end to the mooring device 8 (figure 2), and the second through the swivel to the active unit of the relay 9 (figure 4).

Before the flight, a resettable self-contained radio signal repeater is suspended on the beam holder of the aircraft using the yokes 4 (Fig. 1). During the flight of the aircraft at a given point, the repeater is reset. After separation of the repeater from the aircraft, sections 6 are deflected (FIG. 3) of the aft 3 (FIG. 1). The repeater brakes and stabilizes its angular position. After braking to a given speed, the locks are opened and the hull is divided into two parts: aft 3 (Fig. 1) with an active unit 9 (Fig. 4) and a central 2 with a head 1 part (Fig. 1). Since the resistance of the separated stern with the active unit is higher than 9, it starts to lag, pulling the mooring halyard 10 (figure 4) from the central part 2 (figure 1). After the active unit of the relay 10 exits the central part 2 (Fig. 1), the disclosure of the braking surfaces 5 begins. By the time of the full disclosure of the aforementioned braking surfaces 5 (Fig. 4), the active unit 9 will lag behind the full length of the mooring rope. When disclosing the braking surfaces 5, they begin to rotate and work in the mode of a wind turbine under the influence of high-speed air pressure, creating resistance to movement. After the mooring rope is drawn to its full length, the balloon 7 is filled with compressed gas from the balloon. The head part 1 (Fig. 1) is destroyed upon contact with the earth's surface, and the mooring device 8 (Fig. 2) is embedded in the earth's surface (Fig. 5) and reliably fixes the repeater relative to the earth's surface. The active unit 9 (figure 4) using a balloon 7 and a mooring halyard 10 is held at a predetermined height (figure 5). This ensures the achievement of the required technical result.
