Description

The utility model relates to devices for throwing or launching unmanned aerial vehicles (UAVs), in particular, to individual ones.

Known for the prototype 9P78E self-propelled launcher of the Iskander-E complex for launching UAVs, (“Russia's Arms and Technologies”, Encyclopedia XXI Century, Volume II “Missile and Artillery Arms of Ground Forces”, Arms and Technologies Publishing House, Moscow, are known , 2001, p. 70-81). A well-known launcher includes a vehicle, on the frame of which a cargo platform is installed, containing two pairs of rails for installing two UAVs, a system for lifting and holding rails (p. 81), a hydraulic system for hanging the cargo platform in a horizontal position with four retractable supports, a power supply source with a drive from the electric motor and diesel engine of the vehicle, as well as control and starting equipment (KPA), (p. 77), including the aiming system, KPA control panel, remote control KPA ult, equipment for entering the flight mission and the target’s reference image into the onboard UAV computer (p. 78), gyrocompass installation system (p. 81).

The essential features of the proposed device that match the features of the prototype are the following: a self-propelled UAV launcher, including a vehicle equipped with a cargo platform, containing guides for at least one unmanned aerial vehicle, a hydraulic system for hanging the cargo platform in a horizontal position with extendable supports, source hydropower and control and starting equipment.

In the known device with long time intervals between launches of UAVs, an expensive vehicle is not used, which increases the cost of the fleet of launchers during their manufacture and operation.

The technical result, the achievement of which the proposed device is aimed at, is to reduce the cost of the launcher fleet during their manufacture and operation.

To solve the problem in a UAV self-propelled launcher, which includes a vehicle equipped with a cargo platform, containing guides for at least one unmanned aerial vehicle, a hydraulic system for hanging the cargo platform in horizontal position with extendable supports, a hydropower supply and control and launch equipment, platform mounted on an autonomous chassis and made detachable from the vehicle with the possibility of autonomous operation without it. Additionally, to reduce the cost of the launcher, an overpressure oil tank placed on a cargo platform with pressurization from a compressed gas cylinder through control valves was used as a source of hydropower.

Distinctive features of the proposed self-propelled launcher is that the platform is installed on an autonomous chassis and is made detachable from the vehicle with the possibility of autonomous operation without it; An overpressure oil tank placed on a cargo platform with pressurization from a compressed gas cylinder through control valves was used as a hydropower source.

Due to the presence of these distinctive features in conjunction with the known, the following technical result is achieved - a reduction in the cost of the launcher fleet during their manufacture and operation is ensured; the possibility of free use of the vehicle for the delivery of other goods (additional launchers, spare parts, food, spare UAVs, means of its installation on guide platforms) is provided; the dimensions of the site are reduced to ensure UAV launch, camouflage characteristics of the launch site are improved, the likelihood of hitting a cargo platform with UAVs by enemy countermeasures is reduced, and the number of possible UAV launch points on the ground is increased, which makes it possible to bring the launch pad closer to the area under study and reduce the required radius of action UAV.

The proposed technical solutions can find application both in military technology in the development of mobile weapons, rapid deployment and relocation, low visibility, which also provide launch in conditions of limited size sites, and in sectors of the economy where UAV launch is necessary during search and reconnaissance operations or for aerial photography, with the maximum possible approximation of the UAV to the study area.

The essence of the proposed device is illustrated by the drawings of figures 1, 2.

Figure 1 presents a General side view of the launcher cargo platform detachable from the vehicle.

Figure 2 presents the pneumatic-hydraulic diagram of the hydraulic system for hanging the cargo platform using an excess pressure supercharged oil tank as a source of hydropower from a compressed gas cylinder through control valves.

Presented in figure 1, 2, the device comprises a cargo platform 1 mounted on an autonomous chassis 2, towed to a vehicle (not shown in the drawing) device 3 attached to the platform 1, on which are guided 4 at a starting angle α, in which the UAV is mounted 5. Platform 1 can contain several pairs of guides 4, respectively, and several UAVs 5, which can be located on it both in parallel and in a cellular order. UAV 5 is equipped with a control system 6 and a propulsion system 7. On the platform 1, a hydraulic system 8 is mounted for hanging it in a horizontal position, including sliding supports 9 and a control panel 10. On the platform 1, control and starting equipment 11 with a control panel 12, connected by an electric harness 13 through a tear-off connector 14 with a UAV control system 6 and its propulsion system 7, is also installed. The hydraulic system for hanging the cargo platform includes hydraulic cylinders 15, whose rods 16 are connected to supports 9. A hydraulic power source is installed on the platform 1, including the first oil tank 17 (Fig. 2) with hydraulic fluid 18, in communication with the above-piston cavities 19 of the hydraulic cylinders 15 through the hydraulic fluid supply valves 20, the second oil a tank 21 with a reserve cavity 22 for hydraulic fluid 18, in communication with the piston cavities 23 of the hydraulic cylinders 15, as well as a compressed gas cylinder 24 with a charging valve 25, in communication with the oil tanks 17 and 21 through the valves 26. To increase the degree of tightness of the cylinder 24 during long-term storage in when charged, it is in communication with valves 26 through a start valve 27. To reduce the required initial gas mass and the volume of the cavity of a cylinder 24, it is in communication with oil blocks 17 and 21 through a pressure reducer 28. To increase ground clearance and cross-country ability of the casing, the hydraulic cylinders 15 are mounted on the platform 1 with the possibility of folding by means of hinged joints 29, while the platform 1 is equipped with hydraulic cylinders 30 of the layout of the hydraulic cylinders 15. The hydraulic cylinders 30 are fixed by hinges 31 on the platform 1, and their rods 32 are connected to the hydraulic cylinders 15 by hinges 33, this nadporshnevye cavity 34 (figure 4) of the hydraulic cylinders 30 are in communication with the first oil block 17 through the valves 35, and their podpiston cavity 36 in communication with the second oil block 21.

Self-propelled launcher works as follows. After delivery, platform 1 (Fig. 1) can be installed on a site of reduced length, after which the towing device 3 is disconnected from the vehicle, which is diverted from the launch site and used to deliver another platform 1 to an additional platform or to deliver spare parts, fuel and additional UAV 5. Starting from the control panel 10 of the hydraulic system 8, the starting valve 27 is activated (Fig. 2), then, by controlling the opening and closing of valves 26 and 20, they provide compressed gas from cylinder 24 to oil tanks 17 or 21, under pressure of Hydraulic fluid enters the supra-piston cavities 19 of the hydraulic cylinders 15 or their sub-piston cavities 23, which ensures different outlets of the rods 16 from the hydraulic cylinders 15 and, due to the support of the supports 9 in the ground, different position of the platform 1 and the towing device 3 in space is provided. To improve the cross-country ability by similar operation of the operation of the hydraulic cylinders 30 of the launcher, the cylinders 15 are folded. After receiving the flight task using the remote control 12 of the control and launch equipment 11, route data is entered into the control system 6 through the harness 13 and connector 14 and a command is issued to start the propulsion system 7. Thus, the cost of manufacturing and operating a certain fleet of UAVs 5 is reduced both due to the reduced number of necessary vehicles, and due to the fact that Platform 1 can be moved to a horizontal position without the use of expensive devices — electric pumps and a marching diesel vehicle installation.
