 The rescue device (system) for people in distress includes a search and rescue service (PPS) helicopter serial (MI-8t type) for search and rescue and emergency rescue operations, equipped with necessary equipment and special devices 1, a night device pilot’s visions (serial type PNV) for work in conditions of poor visibility 2, on-board television installation units (type BBTU-1) to ensure operation of BTU-1 3, a control panel for a winch with a cable (type PU LPG-3) for lowering and raising the device capture ATA 4, a television camera (type ТТ BTU-1) for disaster area survey (RB) 5, a winch cable (type ТЛПГ-3) with a length of at least 50 m to ensure the descent and lifting of capture device 6, additional lighting equipment (DSTO, serial headlights) for illumination in the disaster area when searching for and rescuing the injured 7, an indicator light small-sized aerial bomb (OMAB, serial) for illuminating the disaster area (RB) 8, a night-vision device (camera) for night vision devices for crews when operating in low visibility conditions 9, second television camera (type TC BTU-1) d I review disaster area (RB) and the sighting pickup saving means 10, let down to rescue the injured capturing apparatus (with the mesh ring "K-C") to release the rescuer-diver (assistant) and lifting the patient on board the helicopter 11 MSS.

The sketches (see Fig. 6) explain the design features of the device’s suspension units (РЫМ-bolt), “KC” folding structure nodes (A, A ', B) along the A-B axis for ease of transportation on board the PSS helicopter and loading - unloading in working position. Moreover, in the folded position, the power lever-half-arm with stretch marks is between the half rings with a net, which are fixed with special straps and moored inside the cabin of the PSS helicopter
The net can be made of parachute slings or made of metal (depending on the conditions for rescue operations) with reliable fastening to the ring. In the middle of the grid, a cargo indicator G is fixed with a flag on the cable.

 The indicator float 12 to indicate the location of the burial place of the rescue device serves as a guide for the rescuer when delivering the victim to the place during capture from "KC".

 The device also contains a banner 13 for connecting the cable 6 to the safety and stabilizing torch of a rescue scuba diver (paramedic), safety and stabilizing halyard 14 for safety and insurance of a rescue scuba diver (paramedic) during rescue operations, a special belt of a rescue scuba diver (paramedic) to secure of a rescued person during the course of rescue operations 15, safety halyard 16 for communication between the rescuer (lifeguard belt) and a safety-stabilizing halyard, halyard 17 of the rescued person for securing (fixing) it to the rescue belt I when delivered into capture device "K-C" followed redocking the belt device 11, connected to the radio in the disaster area (RB) R-855m (standard "Surf-IV" or the like.) 18.

 The flight technician 19 of the PSS helicopter takes an active part in rescue operations, and the rescue scuba diver (aka paramedic) 20 actively carries out rescue operations and brings the victims aboard the PSS helicopter from the Republic of Belarus (disaster area) and search for the injured 21.

 The block diagram (see Fig. 1) works as follows.

The signal "SOS" is received by the crew aboard the helicopter (B) 1 MSS 1 at 1 entrance, the crew urgently carries out pre-flight training and performs additional operations in accordance with the "Instructions for the crew of the MSS helicopter". Then it takes off with a vertical speed V _d (BC) and follows the ψ course course to the disaster area (RB) with a horizontal flight speed (GP) V _g . Moreover, through the satellite communication channel (NE), it clarifies the coordinates of the disaster area and its coordinates, using the navigation and flight control system, the crew displays the helicopter (B) 1 MSS 1 in the disaster area (RB).

 Crew 1 uses night vision devices 2, 9, the first 1 inputs of which receive information in the Republic of Belarus from the surface of the water (land) with poor visual visibility (or at night).

 Crew В 1 also uses an onboard television installation with blocks 3 and cameras 5, 10, the information on which also comes to the Republic of Belarus from the surface of the water (land) through 1 inputs. After identifying the injured (injured) 21 in the Republic of Belarus, the crew (flight engineer) 19 of the helicopter (B) 1, using the control panel PU 4 with a winch, releases a cable 6 with a rescue lowering capture device 11, bringing it previously into working condition (opening with the removal of the boom of the winch), on 1 entrance.

 Using the remote control 3, 5, 10, additional lighting equipment 7, OMAB 8 and night vision devices 2, 9, the crew B 1 and the flight technician 19 at 1 inputs carry out operations related to the safety of the descent of the device 11 with the scuba-diver (paramedic) 20 so that the deepening of the device 11 was carried out near (3 5 m) from the injured 21 on the water surface (VP), or there was a landing on land.

Moreover, the burial place of the device 11 on the VP is controlled by 1 input-output by a float 12 by 1 input-output 2 with a tie 13 on a cable 6 and a safety-stabilizing halyard 14 on 1 input-output. At the same time, the special belt 15 of the rescue scuba diver (paramedic) 20 through the safety halyard 16 is connected movably to the halyard 15, and the halyard of the rescued (injured) 21 has 1 output and 2 input-output 1 connected to the injured 21. Communication is carried out via (BC) connected RS 18 on 1 exit with an entrance to the crew and rescuer B1 20. The rescuer 20 approaches the victim 21, fastens his halyard 17 to the special belt 15 and tows it to the float 12 of the buried device 11. Communicating (BC) with the B1 crew via RS 18, lifeguard 20 gives a command to lift (V _W ) flight equipment 1 9, securing the previously injured to the cable 6 of device 11. The flight technician 19 through the control unit 4 of the winch B 1 starts lifting the device 11 and simultaneously selects the slack of the hitch 14. The rescuer 20 fixes the injured 21 to the belt in the device 11 and together with the rescued 21 in K-C "board aboard B1, where they transport (transfer) victim 21, give him first aid (with an express analysis of the condition) and dress the victim in dry clothes from the flight kit, etc.

 The operations are repeated and then the victims at B 1 are delivered to the base.

In FIG. 2 shows the main cycles (stages) of saving people in distress, using the device "KC" for its implementation in the most critical operations:
cycle 1, lower the device 11 on the cable 6 from the helicopter (B) 1, on which the network with the ring ("KC") is opened and the braces (P) are tensioned, and the load (G) at the bottom of the network with an indicator (flag) hangs;
cycle 2 buried device 11 with "KC" near the victim 21, the indicator-float 12 remains on the surface of the water (slides along the cable 6). Rescue scuba diver (paramedic) 20 (can go down to “KS”) on the safety-stabilizing halyard 14 approaches the victim 21;
cycle 3 induce on TV W using communication and maneuvering helicopter PSS 1;
cycle 4 in the device 11 in “KC” lifts the lifeguard 20 with the injured 21 together, and the halyard 14 on the extension 13 is fixed to the cable 6;
cycle 5 is final when lifting (and initial 1) is carried out, when it is lowered in the disaster area (RB) above the water surface (VP) with a vertical speed (BC) V _{ow of the} helicopter’s winch (B) 1. Moreover, they try to reduce the rotation speed (w ) "KC" to the minimum value (for which use the halyards 14 and 13 stretch).

 The complete cycle sequence to illustrate the rescue of people in distress is shown in FIG. 3 5.

 In FIG. Figure 3 shows the individual cycles (steps) of using the device and the system as a whole from the moment of receiving the “SOS” signal and taking off of the MSS 1 helicopter from the base with the “v course” course of the disaster area (RB) using the satellite communication channel (Cn) to correct the location ( coordinates) of the helicopter in relation to RB (its coordinates) cycle 1.

 Upon the arrival of the PSS 1 helicopter in the Republic of Belarus, the victim is “searched” using a TV-set and lighting equipment cycle 2. Then K-C is lowered near the victim cycle 3. K-C is buried and its position under water is monitored by a cycle indicator float 4. Next, the rescuer brings the device to the rescue and leads it to the indicator float, using a safety-stabilizing halyard, and carries out a “capture” cycle 5.

 “KC” is hoisted together with the rescued and rescuer aboard the PSS1 helicopter cycle 6. After that, the helicopter returns to cycle 7 in the reverse course (- v course). At the base, the victims are unloaded and delivered to the medical center, and the crew prepares ( refueling) PSS 1 helicopter for the second flight to the disaster area, cycle 8. Cycle 9 repeats cycle 1, etc.

Summarizing, we can characterize the operation of the device by the sequence of operations (functioning algorithm):
1) crew members receive a "SOS" signal from the base with the coordinates of the disaster area (RB);
2) specify the flight route B 1 to the disaster area (RB);
3) check the readiness of system B 1 for departure and the PSS 1 helicopter itself;
4) fly to the disaster area (RB);
5) follows the shortest route to the disaster area (RB) due to the communication Sp (NE);
6) they search for those in distress 21 in the Republic of Belarus (the correction is performed via the Cn channel);
7) detect the rescued (injured) 21;
8) reduce the PSS 1 helicopter by H _min "subscription";
9) conduct a "search" of the saved (injured) 21;
10) direct the PSS 1 helicopter over the injured 21;
11) produce flares, OMAB 8 and other means;
12) report on the detection of 21 victims and their number to the base;
13) prepare and lower the rescue device 11 on the cable 6 with a rescue scuba diver (paramedic) 20;
14) additionally include electrical equipment (lights) 7;
15) use the on-board television installation to guide the signal device 3, 5, 9;
16) point the helicopter (B) 1 PSS using BTU-1 3, 5, 10 to the injured 21 (combine the crosshair on the screen with images of the device 11, the rescuer 20 and the rescued 21);
17) lower the device 11 on the cable 6 with a winch and deepen it near (3 5 m) of the injured 21 to a depth depending on the sea level, providing stabilization of the device 11 (no buildup and rotation w);
18) the rescuer 20 tows the rescued 21 to the device 11, using the safety halyards 16, 17 and special belt 15, focuses on the float 12, communicates with the board B 1 through the PC 18;
19) give a command to lift the device 11 with the lifeguard 20 and the injured 21 on board B 1 with a speed V _ow (BC) so that both are in the device 11;
20) unload the injured 21 and provide him with the first (emergency) medical assistance on board B 1 and conduct an express analysis of his condition, transfer data to the base;
21) take measures to help the remaining victims (dry clothes, rubbing, dressings, etc.) and follow the base in the opposite direction (- j course).
