Description

The alleged invention relates to military equipment. The primary area of use is the destruction of space objects. It can be used to destroy aircraft.

Known manipulator designed to provide quick action and a large departure of the working body with a slight displacement of the output link of the displacement drive, containing multiple articulated parallelogram (AS USSR No. 963847 M. class. V24V 49/00).

However, in this manipulator, a multiple articulated parallelogram is not used as a powerful energy tool with the ability to increase the speed and energy parameters of the input pulse. This quality side of the multiple articulated parallelogram was not used in military equipment.

As a prototype, a device was used for ramming an aircraft, containing a steel thin-walled body in which a cat with a cable was placed, a pyro-charge for throwing out a cat. Steel cat with teeth opening from the action of the spring (ah. USSR No. 65104 M. class. F42B 13/26).

This device is not capable of hitting space objects, which, as a rule, have a strong multilayer shell. The low striking ability of the known solution is due, firstly, to the insufficient speed and energy indicators of the cat at the time of hitting the target, since a small pyrocharge is used to throw the cat out, and secondly, the moment of the cat's ejection is determined visually, which leads to both premature and belated emissions. With premature emissions, kinetic energy is lost, and with belated projectiles due to projectile ricochets, the target is not affected at all.

The aim of the invention is to increase the striking ability.

This goal is achieved by the fact that in a projectile for hitting aircraft, comprising a body, a striking organ, a pyro charge for ejecting a striking organ, the striking organ is connected to the body by a multiple articulated parallelogram and provided with a sensor for achieving the target, and the leading part of the multiple articulated parallelogram is connected to a piston mounted in a multiple articulated parallelogram connected with a piston mounted in the housing chamber, in the working part of which a pyro-charge is placed to eject the damaging organ.

In addition, the projectile is equipped with an additional multiple articulated parallelogram mounted perpendicular to the main one.

Also new is the implementation of the sensor for achieving the goal in the form of a pin, at the end of which a piezoelectric element is connected, which is electrically connected with a pyrocharge to eject the damaging organ.

Distinctive signs from the prototype are significant, since each of them is necessary, and all together with the restrictive ones are sufficient to achieve the goal.

So the placement of the pyro charge in the chamber with the piston allows to achieve greater acceleration of the damaging organ compared to the prototype, which increases the damage ability. Indeed, in the prototype, the maximum pressure of the gases generated during pyrolysis combustion is almost equal to the value at which the damaging organ moves from its place. With further burning of the pyrolysis, the pressure on the bottom of the striking organ does not increase, but will drop to zero, since after the latter has left the charge body, the gases are scattered in vacuum.

Such a sign as the presence of a connection between the piston and the striking organ, ensuring their simultaneous movement, allows to increase the duration of the accelerating force on the striking organ and thereby increase its speed and striking ability. In the prototype, the accelerating force acts on the damaging organ for a very short time while it is in the pyrolysis case. In the stated solution, the accelerating force is valid all the time from the explosion of the pyro charge to the destruction of the target.

The connection between the piston and the striking organ in the form of a multiple articulated parallelogram, in which the driven part contains n times more parallelograms than the leading one, is also a factor that increases the striking ability. This is due to the fact that with a rigid connection between the piston and the striking organ, the force created by the explosive gases gives the same acceleration to all elements of the system. In the claimed solution, this force is distributed between the piston and the striking organ in proportion to the ratio of parallelograms in the leading and driven parts of the multiple articulated parallelogram. Since with the claimed form of communication, as compared with rigid, the damaging organ accounts for a large amount of force, the acceleration and, as a result, the damaging ability will be higher. Let the force created by the explosion of a pyro charge be equal to 100 units; the masses of the piston and the projectile are the same and equal to a unit of mass; the number of parallelograms in the driven part of the multiple hinged parallelogram is 9, and in the leading 1. Then, from the expression for hard connection:

F = a * (m nop + m org)

where: m nop is the mass of the piston

m org - mass of the damaging organ

We find:

For communication in the form of multiple articulated parallelogram, the expression

F = a nop * m nop + a org * m org

where: and then - the acceleration of the piston

and org - acceleration of the damaging organ

Transforming this expression, we get:

F = a nop * m nop + 9 * a nop * m org

100 = a nop * 1 + 9 * a nop * 1

а орг = 9 * а пор = 9 * 10 = 90 ед

and org = 9 * and then = 9 * 10 = 90 units

Thus, the use of a multiple articulated parallelogram with n = 9 compared to the rigid connection of the piston and the damaging organ allows increasing the acceleration of the latter by almost 2 times.

The installation of an additional parallelogram perpendicular to the main one increases the stiffness of the connection between the piston and the striking organ, thereby eliminating rebounds and increasing the striking ability.

Of the distinctive features of the prototype features it is known the use of multiple hinged parallelogram in the invention by A. with. USSR No. 963847. However, in the inventive projectile and in the known solution, multiple articulated parallelogram has different purposes, and its different properties are used. In the known solution, a multiple articulated parallelogram is designed to ensure speed and achieve a large reach of the working body with a small movement of the leading link. In the claimed projectile, it is used to increase the striking ability due to the property of increasing the speed parameters of the input pulse as many times as many times the number of parallelograms of the driven part is greater than the number of parallelograms of the driving part. The remaining distinctive features from the prototype in the found analogues were not found, therefore, the claimed projectile meets the criterion of "significant differences".

The invention is illustrated by drawings of various modifications of the projectile, where in FIG. 1 shows a front view of the projectile before the pyro-charge is triggered; in FIG. 2 front view of the projectile after the pyro-charge is triggered; in FIG. 3 side view of the projectile after the pyro-charge is triggered.

The projectile for hitting aircraft includes a steel casing 1, connected by multiple articulated parallelogram 2 and an additional multiple articulated parallelogram 3 with the striking organ 4. An additional multiple articulated parallelogram 3 is installed perpendicular to the main parallelogram 2, which gives rigidity to the structure. The main multiple hinged parallelogram consists of the leading part 5 and the driven part 6. The leading part 5 of the parallelogram 2 is installed in the cavity 7 of the housing 1, and the hinge between the driven and driving parts is fixedly mounted in the housing, and the opposite hinge of the leading part is connected by a rod 8 to the piston 9 located in the chamber 10, filled in the sleeve screwed in the housing 11. In the working part of the chamber 10 is mounted on the piston 8 a pyro-charge 12 for ejecting the working body 4. An additional multiple articulated parallelogram is mounted on the housing with p by the power of two hinges installed in the slot 13 of the protrusion 14. The slot 13 is made perpendicular to the cavity 7. On the striking body 4 there is a target achievement sensor made in the form of a pin 15, at the end of which a piezoelectric element 16 is fixed, which is electrically connected through the amplifier to the pyrocharge to release the striking body 4.

The inventive projectile is aimed at the target and with the help of any projectile charging or non-charging device is thrown in its direction. In the future, tracking and guidance on the target is carried out by an automatic homing system installed in the striking organ. When a projectile reaches a target, a piezoelectric element first encounters it, which produces a current from a shock. This current is amplified by an amplifier and initiates a pyrolysis explosion. The gases generated during the explosion press on

        the piston 9 and move it along the chamber 10 from the main multiple articulated parallelogram fixed in the hinge body. The piston 9 through the rod 8 pulls a free hinge of the leading part 5, bringing it together. Simultaneously with the leading part, all links of the driven part 6 are reduced. Since, at the same time, the striking organ travels n times (where n is the number of links of the driven part) more than piston 9, it means that the speed of the striking organ V2 will be n times more piston speed V1.

V2 = n * V1

The high speed of the ejection of the striking organ causes its high kinetic energy, and, consequently, high destructive ability.

Compared with the prototype of the claimed charge has a greater destructive ability. Firstly, due to the use of a chamber with a piston, the connection of the piston with the striking organ with a multiple hinged parallelogram increases the speed of the striking organ. Secondly, thanks to the target achievement sensor, the exact moment of the ejection of the striking organ is ensured. In the prototype, the moment of ejection of the striking organ is determined visually, and therefore, the probability of untimely ejection of the striking organ is high. With premature emissions, part of the kinetic energy is lost. In case of delayed emissions, the projectile first ricochets from the target, and then the striking organ is ejected past the target.

Compared with modern systems of warfare in space, for example, laser weapons, the claimed projectile is simple and cheap. Indeed, for the implementation of military operations by a laser installation and its systems, it is necessary to produce an atomic bomb in space. A powerful light stream from the explosion is absorbed by the laser unit, turning it into a laser beam. The implementation of such a method of warfare entails enormous costs.

The increase in the speed of the damaging organ in the claimed solution compared to the prototype is confirmed by the following simplified calculation.

The maximum pressure of explosive gases in the prototype is approximately equal to the pressure of forcing (250-500 kg / cm2). In the claimed solution, due to the enclosed space of the chamber with the piston, it is 6-10 times larger (see "Manual on the Small Arms", Ministry of Defense, 1973, p. 6-8). The time of action of explosive gases on the damaging organ in the prototype is very short and almost equal to the formation time. In the claimed solution, the time of action of explosive gases on the piston is about 10 times longer than the formation time and is equal to the period from the beginning of forcing to hitting the target.

Given the following conditions:

- the ratio of the number of parallelograms in the driven part to the number of parallelograms in the driven part is n = 9;

- the mass of the piston is equal to the mass of the damaging organ m nop = m org = m o;

- the mass of multiple articulated parallelogram is neglected, since the mass of the piston is deliberately overstated;

- the cross-sectional area of the piston and the striking organ is equal to S then = S org = S about.

We make up the equations:

where: P ol - the pressure of explosive gases in the prototype, equal to about 400 kg / cm2

t CR - the time of the pressure of explosive gases on the damaging organ in the prototype

R application - the pressure of explosive gases in the claimed solution, equal to about 2800 kg / cm2

t application - the time of action of explosive gases on the piston in the claimed solution is approximately 10 t CR

Substituting numerical values and expressing some quantities through others in equations 1 and 2, we obtain:

Dividing equation 2 by equation 1 we get:

Transforming, we get:

Thus, the speed of the striking organ in the claimed solution is approximately 60 times higher than the speed of the striking organ in the prototype.
