The invention relates to defense systems, in particular to the guided rockets being shot off from the tubular guide containing the Assembly of the two sequentially telescopically connected sections, the hull of which is made of thin-walled shells.

The telescope is widely used in missile and is used in almost all managed missiles.

The advantage of this type of compounds are the small dimensions of the joint compared with flanged connections, however, in buildings of connected compartments, you must perform the seats with the screw holes under the radial screws, and in a classic case of a telescopic connection by tightening the screws get clearance for landing the ends of connected compartments, causing the entire load when launching and flying rockets in docking place falls on the screws.

A characteristic feature of guided missiles being shot off from the tubular guides, is the presence of large upfront axial overloads, resulting in possible slice of the screws, which would entail the destruction of missiles in General.

Execution seats with threaded screw holes in the hull compartments leads to an increase in the thickness of the body at the junction, which reduces the inner diameter of the compartment, through which runs the lips of the mounting charge of solid fuel in a propulsion engine or an explosive charge casing of the warhead, accordingly, reducing the effectiveness of the warhead and reducing the diameter of the charge of solid fuel. The use of thin-walled shells compartments for main engine and warhead without making threaded seats allows you to make maximum use of a given caliber rockets in filling its large number of explosives and solid fuel.

Known guided missile "faggot" [Shell M(M-2). Technical description and operating instructions, Military publishing house of the Ministry of defense of the USSR, M., 1975, S. 11, Fig.5], adopted for the prototype, in which this problem has been solved by installing between the two compartments, cases of which are made in the form of thin shells, transitional frame, which are telescopically connected by radial screws with each of the compartments on the outer surface of the frame is made of special protruding collar that their side surfaces interacts with the thrust surfaces of the two compartments.

The disadvantages of this method of Assembly of the two compartments, made of thin-walled shells are a great length of the intersection of two compartments, the need to perform is actually two telescopic connection, the first compartment from the frame and the second compartment from the frame, the requirement of high precision manufacturing poverkhnostyami, interacting with the inner surfaces of the shells of the two compartments, with the aim of ensuring their alignment.

The task of the invention is to increase the efficiency of the rocket through the creation of reliable telescopic connection propulsion motor and warhead.

The solution of this problem is achieved in that in a controlled rocket being shot off from the tubular guide containing an Assembly of series-connected two compartments, mainly sustainer engine and warhead, a cylindrical thin-walled shell telescopically connected without performing the screw holes. In the first compartment is made conical hole for the screw head, the second cylindrical hole. The connection is made by radial screws with conical head, conical head is made of a cylindrical surface that interacts with the cylindrical surface of the second compartment, and a tapered section with a tapered bore of the first compartment.

To ensure the strength of the joint to effect axial overloads the distance from the tapered hole of the first compartment to its hard surface is made larger than the distance from the cylindrical hole to the thrust surface of the second compartment, and radial screws placed in the same plane with the connected compartments.

In private the case of radial screw its threaded part cooperating with a threaded surface of the nut, installed on the inner surface of the second compartment.

The second particular case of the threaded portion of the radial screws communicates with a radial threaded holes formed in the annular part, freely installed inside the second compartment.

Thus, the screw head simultaneously interacts with both shells compartments, ensuring reliable contact compartments on their backs.

The proposed solution is illustrated graphic material (Fig.1-4).

In Fig.1 shows a missile containing the Assembly of the two compartments 1 and 3 (main engine and warhead, respectively), cases of which are made of thin-walled shells, United radial screws 2.

In the first case is made landing place for the installation therein of the second building. The Assembly of the two compartments is carried out by setting the radial screws 2 that interacts with a conical and a cylindrical bore compartment 3 and 1, respectively, and the threaded part of the threaded part of the nut 4, which is freely mounted on the inner surface of the cover 3 (Fig.3).

The distance b from the end seats of the first housing to the axis of the conical hole is larger than the distanceandfrom the end of the second housing to the axis of the cylindrical hole (Fig.2). This allows for the tightening of screws to secure the tightness p. the surfaces G (thrust surfaces of the first and second compartments, for conical and cylindrical surfaces of the holes and screws, and other surfaces is provided gap) (Fig.3).

In this case the tightness on the surface of G provides a more reliable connection of the compartments and the load acting on the rocket at the start of the joint are already on the hard surface of the connected compartments.

However, when assembling the two compartments of the guided missile aside from the difficulty in installing the nuts on the inside of the compartment, therefore, serves to screw the screws into the threaded holes of the annular part that is installed inside the second compartment (Fig.4).

The proposed solution allows to provide a reliable connection of the two compartments, cases of which are made of thin-walled shells, without using an additional frame, increasing the length of the seam, reduce the number of docking places due to unloading of the screws from the start of congestion, to improve the efficiency of the rocket by reducing the length of the connection of the two compartments, thereby freeing up space under the charge of solid fuel and explosive, thereby increasing the range and effectiveness of the warhead.

SUBSTANCE: invention relates to methods for hitting of underwater targets. The method to hit underwater targets consists in delivery of a detachable warhead of underwater action to a target location area, separation of a warhead in the end section of flight trajectory and its actuation after landing on water. The detachable warhead is delivered by the first missile. Prior to delivery of the warhead to the target location area, they deliver one radio hydroacoustic buoy. The buoy is delivered by the second missile. After buoy landing on water, as the first missile gets closer to the area of target location, by means of equipment placed on it, they provide for reception of information from the buoy on location of the target, and the point of warhead landing on water is corrected. Cruise missiles are used for delivery of the warhead and buoy to the area of target location. The cruise missile is equipped with a sustainer power plant with an air jet engine. The speed of acceleration of each missile by a speeding device in the initial section of the trajectory is limited by the value sufficient for development of an aerodynamic lifting force that sustains the flight and to start the sustainer engine, afterwards they provide for its separation from the speeding device, start of the sustainer engine and further flight to the area of target location in the atmosphere. Correction of the point of warhead landing on water is carried out due to correction of the trajectory of the first missile flight by confirmed coordinates of the target and separation of the warhead closer to the target.

EFFECT: invention provides for reduced mass of a missile complex.
