Description

 The invention relates to the field of military equipment and can be used to design mines of directed action in a wide range of tasks.

When determining the level of technology, publicly available information was used, presented in the following sources of information:
published descriptions of title documents, applications for inventions (RU 2079100 C1, 05/10/1997);
Soviet and other publications available in the library;
Messages transmitted via radio, television, cinema, etc.

 The analysis of this information showed that the well-known, widely used directional mines (directional explosion mines) allow you to affect an object in the immediate vicinity of it, at a distance of several meters to several tens of meters.

 The disadvantages of such mines of a directed explosion include a limited range of effective action with the need for a sufficiently close operation of the mine from the target. In addition, even with significant changes (increases) in dimensions in mines of a directed explosion, it does not seem technically possible, respectively, to significantly increase the accuracy, range and effectiveness of the impact on the object.

 The problem to which the invention is directed, is the creation of a new type of directional explosion mines, which will increase the accuracy, range and effectiveness of the impact on the object and thereby allow the object to be affected at a considerable distance from it.

 The technical result that can be obtained by using it is that the parameters of the propelled body are increased (weight, volume), that is, the mass of the propelled mine increases to the level of widespread use (up to several tens, hundreds of kg); the range increases (up to 10 km) and the accuracy of the impact on the object, thereby significantly increasing the effectiveness of the impact on the object at a considerable distance from it, which allows us to solve a wider range of tasks.

 The solution to this problem is achieved by the proposed directional long-range mine, comprising a housing, a propulsion charge, a payload and electric igniters, in which the propulsion charge is placed in steps separated by baffles, each of which consists of combustion chambers separated by baffles with propelling charges and electric igniters, moreover the combustion chambers are connected by an electric circuit, and the last of the combustion chambers is a locking mechanism.

 In addition, the number of steps can be from two or more.

 In addition, the number of combustion chambers can be from two or more.

 In addition, the steps can be made with the possibility of their sequential inclusion.

placed in combustion chambers, separated by inter-chamber partitions and interconnected into an electrical circuit, and a missile body, which is a mine. To simultaneously initiate electric igniters are connected by an electric circuit. The characteristics of the MNDD on D 3C vary, depending on the tasks to be solved, by changing all the structural elements tied into a single whole.

 In our proposed MNDD on D 3C, the acceleration of the missile body (mines) is carried out by placing steps with a propelling charge in the mine’s body, the steps are divided into combustion chambers with a propelling charge with several ignitors, which made it possible to increase the throwing speed when compressing the propellant charge consumption (reducing the weight ratio charge of fuel to the weight of the missile), reduce the overall size of the structure for existing combat characteristics, increase the weight of the missile (mines), increase the length of the flight path e exit the launch tube.

 The essence of the invention is shown in the drawings. Figure 1 shows a General view of the MNDD on D 3C, where the barrel is a pipe (12) with a mine (1), consisting of a propulsion charge in the housing (5) and a payload (3), the propulsion charge consists of stages (4a, 4b 4c) with partitions (2). In FIG. Figure 2 shows the MNDD stage at D 3C, where the stage body (11) is divided into combustion chambers (6a, 6b, 6c) with inter-chamber partitions (10), the combustion chambers have a propellant charge (8) in the body (9) with electric igniters (7 ) connected by an electric circuit.

 A mine (1) with a payload (3) is accelerated in the launch tube (12) using a propulsive charge in the housing (5), the design of which ensures the sequential operation of the stages (4a, 4b, 4c), respectively, the gradual dispersal of the mine (1) and complete combustion of a combustible substance (8) from igniters (7), in which the TUSS Kamerny device still does not collapse due to an explosion caused by pressure overload placed in the combustion chamber (6a, 6b, 6c).

 The proposed device operates as follows.

 After the electric power is supplied to the “TUSS chamber” with the help of series-connected electric igniters (7), the combustible substance (8) of the first stage (extreme to the outlet) (4a) is simultaneously ignited in the combustion chambers (6a, 6b, 6c). Inside the combustion chambers (6a, 6b, 6c) a pressure is created corresponding to the condition of the burning rate. The combustion products of a combustible substance (gas, compressed to a high density), expanding, press on the body (1) and inter-chamber partitions (10). Under the gas pressure in the combustion chambers (6a, 6b, 6c), the interchamber partitions (10) are set in motion, while: in the combustion chamber (6a), one interchamber partition (10) pushes the partition (2) in front of itself to the next stage (4b) , the inter-chamber partition (10) presses on the combustion chamber (6b); in the combustion chamber (6b), the inter-chamber partition (10) presses on the combustion chamber (6a), the inter-chamber partition (10) presses on the combustion chamber (6c); in the combustion chamber (6c) the inter-chamber partition (10) presses on the combustion chamber (6b), another inter-chamber partition (10) pushes the partition (10) out of the mine shell (1) to the outside. In each stage (4a, 4b, 4c, ... 4n), the combustion chamber extreme to the outlet (6c) acts as a locking mechanism, thereby ensuring that the gases of the remaining combustion chambers (6b, 6c, ... 6n) respond to the pressure of the subsequent stages (4b, 4c, 4n), driving the entire grenade structure (1) inside the launch tube (12) and further outside the pipe, due to the successive operation of the remaining stages (4b, 4c, ... 4n).
