Description

The technical field to which the invention relates.

The invention relates to airborne weapon platforms (suspensions).

State of the art.

Known airborne weapon platform, containing assemblies of barrels, including the barrel, a plurality of projectiles located axially in the specified barrel with close working contact with the barrel bore, propellant charges for sequential ejection of shells through the muzzle of the barrel. In this case, at least one of the barrel assemblies includes a barrel, which is an element of the aircraft structure that moves the weapon platform. Barrels can be made of composite material. Barrel assemblies can form wing spars or an aircraft fuselage [patent (RU 2309358)].

Also known is a launcher for projectiles containing a mobile unit of several barrel launchers, in the barrels of which several projectiles are placed one after another. Each projectile is associated with a separate individually flammable propellant charge for sequential ejection of projectiles through the barrel outlet. Each projectile has a body in which substances or objects can move. The unit may contain a means for controlling the orientation of the barrels for adjusting the position of the barrel launchers relative to each other along the angle between their axes to change the position of the points of impact of the projectiles fired from different barrels. The present invention can be applied using both an unmanned aerial vehicle and a manned one [patent (RU 2254540)].

These inventions are taken as prototypes of the present invention. However, they have disadvantages. In an airborne weapon platform [patent (RU 2309358)], the disadvantage is that the barrel assemblies are elements of the aircraft structure and form the wing spars or the fuselage of the aircraft structure that moves the weapon platform, which requires significant structural changes to the aircraft at the design and construction stage , actually creating a special vehicle. Both the patent (RU 2309358) and the patent (RU 2254540) use a large number of charges with a design developed by the authors of these patents, which must be created, since they are not produced by the industry, which significantly complicates both technical and financial the point of view of the process of implementation and application of these structures and ammunition to them. In both patents, the charges are arranged sequentially one after the other in large numbers, respectively, loading charges with charges can take a significant amount of time, this equipment time can be unsatisfactory in cases where time is a key factor. Weapon designs indicated in these patents are difficult to use in hard-to-reach places for pinpoint strikes and destruction of small enemy groups.

Disclosure of the invention.

The technical objective of the invention is to create such weapons and a method of their use that will allow hitting enemy manpower and light vehicles in hard-to-reach places (urban conditions, gorges, etc.), as well as the mandatory conditions for this weapon should be:

- the ability to quickly organize its production,

- available components,

- the use of ammunition in service,

- remote use without endangering personnel,

- operator training minimum time, simple application,

- in connection with the above, the cost of production and use tending to a minimum.

To achieve this technical task and fulfill the mandatory conditions, a project was developed for the suspension of an unmanned aerial vehicle for vertical take-off and landing of the copter type and a method of its use. The essence of this project is to retrofit the drone with a suspension for delivering ammunition to the target, which is in service with the Russian army.

The suspension is:

1. Mount the suspension.

2. A barrel for ammunition or several barrels, depending on the carrying capacity of the unmanned aerial vehicle.

3. Control unit.

4. Remote control.

An unmanned aerial vehicle equipped with a suspension with ammunition is a mobile combat unit capable of moving stealthily for the enemy at a sufficiently high speed, which makes it possible to perform tasks for the remote destruction of both enemy manpower and unarmored vehicles in areas of terrain that are difficult to reach for existing weapons. especially in a street fight. Similarly, an unmanned aerial vehicle equipped with a gimbal can be used for peaceful purposes in police units and other law enforcement agencies. For firing multiple projectiles from such suspensions at a given target, minimal preparation time is required. This is an advantage in situations where time is a key factor, such as taking down an enemy in a street fight.

In a preferred embodiment, the barrel launcher refers to devices that fire projectiles such as hand grenades, if necessary, they can be loaded with different types of ammunition and can have different bore diameters. Suspension firing can be conducted from an aircraft or from several aircraft, if necessary coordinating actions between the aircraft over the communication line.

Hand grenades such as RGD-5, F-1, etc., which are already in serial production and are included in the soldier's ammunition, are preferably used as ammunition. The gimbal can be pre-loaded so that the individual barrels contain ammunition of various types and weights. The dumping of ammunition can be carried out in such a way that a group of exploding grenades covers the desired area in a given order.

Unmanned aerial vehicle 2, shown in figure 5, carries six barrels in its suspension, each with one grenade, it is assumed that each suspension can accommodate six grenades. In this case, the ammunition capacity will be six hand grenades such as RGD-5, F-1, etc. with a total weight of 1.8 to 3.6 kg, depending on the type of hand grenades used, the total weight of the six ammunition will be 1.5 kg. The maximum weight of the drone suspension ammunition will be 3.6 kg, which does not exceed the carrying capacity of multicopters in production. In this version, the targeting of the suspension trunks is carried out by means of remote control of the drone through the installed video camera, which helps the operator to control the aircraft and the suspension to it from a distance.

Implementation of the invention.

Suspension with ammunition for an unmanned aerial vehicle works as follows. Before using the drone, the drone operator equips it with ammunition (such as RGD-5, F-1, etc.) as shown in figure 2. Hand grenades are placed in the suspension barrel (figure

2) with a fuse (8) up to the stop in the suspension body, fixation is made by compressing the grenade body (2) and the grenade lever (7) with a movable retainer with a rubber coating (4) by rotating the servo (5) in the direction (11). Through the technological holes (8) (figure 1), after compressing the charge in the barrel cylinder, unbend the tendrils of the safety check, pull out the check ring (7), due to the fact that the lever is tightly fixed together with the grenade in the barrel, the ammunition will remain safe until it is dropped. At the moment of hovering over the enemy (the recommended height is 35-40 m), the operator, through the gimbal control panel, gives a command to dump the required amount of ammunition (it is recommended in pairs 2, 4, 6 to balance the copter). The servo retracts the movable retainer, and the hand grenade, under its own weight, comes out of the barrel cylinder, at this moment the hand grenade lever, under the influence of the drummer spring, will turn, freeing the drummer, and fly to the side, the ammunition will rush towards the enemy and after 3.2-4, An explosion will occur for 2 seconds. If necessary, the charges can be brought into a safe state suitable for storage (insert the pin and bend the antennae through the technological holes).

The method of using a suspension with ammunition for an unmanned aerial vehicle is shown in figure 6:

I - moving the drone behind an obstacle, visual contact of the enemy and dumping the required amount of ammunition (by the decision of the drone operator, depending on the number of the enemy) in pairs for correct weight distribution of the drone.

II - return for an obstacle to exclude the defeat of the drone by fragments of dropped ammunition or enemy fire.

III - return for visual contact of the defeat of the enemy and, if necessary, additional discharge of ammunition.

Quickly bringing an unmanned aerial vehicle equipped with a gimbal into readiness for use, its remote use

increases the efficiency of hostilities (counterterrorist operations), restoring law and order, and reduces the loss of personnel, and the available components for its production and the ammunition available in service allow, without additional costs, to organize its production and use in the shortest possible time.
