Technical Field

The application relates to the technical field of missile thrust vector control equipment, in particular to a gas-driven missile swinging spray pipe.

Background

The traditional rocket engine jet pipe can only provide thrust in the direction of a missile shaft, and the missile needs to realize posture adjustment by means of asymmetric aerodynamic moment generated by deflection of an aerodynamic rudder piece. Along with the gradual improvement of the requirement of the missile on maneuverability, the attack angle is larger and larger, and the aerodynamic rudder piece cannot meet the combat requirement easily. In contrast, the thrust vector technology generates the torque required for controlling the missile by controlling the deviation of the main thrust relative to the missile axis, does not rely on aerodynamic force, and can generate large control torque even at low speed or high altitude. The thrust vector control system using the swinging spray pipe has high control efficiency, small thrust loss and low energy requirement of a control mechanism. Thrust vector control techniques are therefore increasingly being used.

A commonly used technical means is that a servo motor is used as a source of a swinging driving force of a spray pipe, but the servo motor is complex in mechanical structure and high in manufacturing cost, is difficult to integrate into the integral design of a missile, is high in power for generating large control torque, and extremely high in power requirement, and brings certain difficulty to production.

Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Refer to fig. 1, which schematically illustrates a structural diagram of a gas-powered missile swinging nozzle provided by an embodiment of the present application.

The gas-driven missile swinging nozzle provided by the embodiment of the application comprises a combustion chamber 1 and two single-shaft swinging double-nozzle assemblies which are arranged on the same end surface of the combustion chamber 1 in parallel and symmetrical arrangement. The single-shaft swinging double-nozzle assembly is connected into the combustion chamber 1 through a pipeline assembly.

The two single-shaft swinging double-nozzle assemblies are identical in component and symmetrical in structure. The single-shaft swinging double-nozzle assembly is completely assembled by splicing.

In the embodiment of the application, all the components are spliced, the structure is simple, the integral forming method in the traditional method is not adopted, and meanwhile, the problem of difficulty in manufacturing caused by the integral forming method is avoided.

Fig. 2 is a schematic structural diagram of a single-shaft swinging dual nozzle assembly according to an embodiment of the present invention.

Any single axis swinging double nozzle assembly presents an axisymmetric structure with the center line of the center seat 9.

Wherein, center seat 9 is arranged at the middle position of the single-shaft swinging double-nozzle assembly. The central seat 9 is a rectangular parallelepiped.

Two symmetrical side surfaces of the central seat 9 are respectively provided with a step-shaped lateral swing nozzle support 4 through screws. The two laterally oscillating lance holders 4 are of identical construction.

The lateral swing spray pipe support 4 is far away from the outermost step of the central seat 9, and a spray pipe ball head base 7 is installed through screws.

Fig. 3 is a connection diagram of a thrust shaft and a ball-and-socket nozzle according to an embodiment of the present application.

Specifically, the nozzle bulb base 7 is a hollow structure, the lower portion of which is cylindrical, and is one of the pipe sets used for being connected with the combustion chamber. The middle part extends outwards on the basis of the cylinder. The upper part is a ball head.

A nozzle ball base 7 is connected with a ball socket nozzle 6 through a shaft hole reserved at the ball head position and a nozzle rotating shaft 10. The ball-and-socket nozzle 6 oscillates about the nozzle axis 10. The bottom surface of the ball socket spray pipe 6 is cut at a swinging angle according to needs, and when the cutting surface of the ball socket spray pipe 6 is in contact with the middle surface of the spray pipe ball head base 7, the swinging angle is limited. The actual cutting angle can be adjusted as required by the actual swing angle.

And a shaft hole is reserved in the swing nozzle support 4, and the shape of the shaft hole is matched with that of the cylindrical thrust shaft 11.

End covers 5 are symmetrically arranged at two ends of the swinging nozzle support 4 respectively. The gaps between the two end caps and the thrust shaft 11 each form a first air chamber 14-4 and a second air chamber 14-5.

The pressure difference between the first 14-4 and second 14-5 chambers will force the inferential shaft 11 to move in the shaft hole.

The middle of the thrust shaft 11 is provided with a square through hole. The ball socket nozzle 6 is embedded into the square through hole through the convex part to form a revolute pair.

The axial translation of the thrust shaft 11 is converted by the convex portion into a rotation of the ball-and-socket nozzle 6 about the nozzle axis of rotation 10.

FIG. 4 is a top cross-sectional view of a single axis swing dual nozzle assembly according to an embodiment of the present application.

As clearly shown in fig. 4, the center of the center base 9 is a cylindrical through hole, and the two sides of the cylindrical through hole are respectively provided with multiple stages of concentric circular steps.

The cylindrical through hole is provided with a strip cylindrical air passage control shaft 12. The air passage control shaft 12 in the embodiment of the present application may be turned from a cylindrical metal rod.

Two ends of the air path control shaft 12 are connected with one side of the magnetic suction block 13 through preset processed threads.

The other ends of the magnetic blocks 13 are respectively provided with an electromagnet 3. The electromagnet 3 is cylindrical. A movable space is reserved between the magnetic block 13 and the electromagnet 3.

The electromagnet 3 is fixed at the round step closest to the shell in the center seat 9 through the magnet cover 2.

When the electromagnet 3 on any side is electrified, the magnetic suction block 13 is attracted to drive the air path control shaft 12 to move between the electromagnet 3 and the central seat 9 along the axial direction, and the total stroke is 2 mm. By the arrangement, when the electrified magnet is switched, the magnetic attraction can be quickly and in place.

In the embodiment of the application, a plurality of channels are provided, which are key factors for realizing swing, different channels are combined and connected, and corresponding torque is provided for the swing of the ball socket nozzle 6. The passageway generally is long and thin hole, but the integrated into one piece technique among the prior art makes the manufacturing of long and thin hole very difficult, but this application adopts the mosaic structure design, has effectively shortened the length of every hole to the processing degree of difficulty has been reduced.

FIG. 5 is a left side cross-sectional view of a single axis oscillating dual nozzle assembly according to an embodiment of the present application. FIG. 6 is a perspective view of the internal passage of a single axis oscillating dual nozzle assembly according to an embodiment of the present application.

The channels in the embodiments of the present application will be described in detail below in conjunction with other components provided in the embodiments of the present application. The channels include an inlet channel 14-1, a first channel 14-2, a second channel 14-3, a first outlet channel 14-6, and a second outlet channel 14-7.

One side of the cylindrical surface of the air path control shaft 12 is connected with an air inlet channel 14-1 which is positioned at the lower half part of the single-shaft swinging double-nozzle assembly and is vertically arranged. The filter 8 is connected to the central seat 9 by means of an inlet duct 14-1.

It should be noted that the inlet duct 14-1 is the second duct set. The gas filters the residue through the filter 8, prevents that the two nozzle assembly internal passage of unipolar swing from blockking up.

The air passage control shaft 12 is connected to the first passage 14-2 and the second passage 14-3 at predetermined positions on the cylindrical surface thereof.

The first channel 14-2 and the second channel 14-3 are in a splayed structure and are symmetrically distributed.

The other end of the first passage 14-2 is connected to the first air chamber 14-4.

It should be noted that the first channel 14-2 and the second channel 14-3 are formed by splicing a hole in the center seat 9 and a hole in the lateral swing nozzle support 4, and a small groove is milled at the spliced position to install a red copper gasket 15, so that the air tightness of the connection is ensured.

The other end of the second passage 14-3 is connected to the second air chamber 14-5.

The other side of the cylindrical surface of the gas path control shaft 12 is respectively connected with one end of a first gas outlet channel 14-6 and one end of a second gas outlet channel 14-7 which are positioned at the upper half part of the single-shaft swinging double-nozzle assembly and are vertically arranged.

The other ends of the first outlet channel 14-6 and the second outlet channel 14-7 are in contact with the outside air.

Fig. 7 is a schematic view of an air passage control shaft according to an embodiment of the present disclosure.

In the embodiment of the present application, the air path control shaft 12 is sequentially provided with a plurality of concave sections and a plurality of convex sections at intervals from one end to the other end. As shown in FIG. 7, the gas path control shaft comprises a concave section 16-1-1, a convex section 16-2-1, a concave section 16-1-2, a convex section 16-2-2 and a concave section 16-1-3 in sequence from one end to the other end.

When any concave section is contacted with any channel in the process of moving towards either end of the air path control shaft 12, the channel is in a communication state. If any convex section is contacted with any channel, the channel is separated from the gas.

The working process of the gas-driven missile swinging nozzle provided by the application is specifically explained in the following by combining the specific working process.

If the left electromagnet 3 is electrified and the right electromagnet is not electrified, the left magnetic attraction block 13 is attracted to the electromagnet 3 under the action of magnetic force to drive the gas path control shaft 12 to move towards the left side, the concave section 16-1-2 in the center of the gas path control shaft 12 enables the gas inlet channel 14-1 to be simultaneously communicated with the first channel 14-2, and the convex section 16-2-1 and the convex section 16-2-2 enable the second channel 14-3 and the first gas outlet channel 14-6 to be in an isolated state and cannot be communicated with the gas inlet channel 14-1. Thus, the combustion gas exits the combustion chamber 1, passes through the inlet channel 14-1, passes through the first passage 14-2, and then reaches the first air chamber 14-4. At this time, the pressure in the first air chamber 14-4 is equal to the great pressure in the combustion chamber.

Meanwhile, the right concave section 16-1-3 of the air passage control shaft 12 connects the second outlet channel 14-7 with the second channel 14-3, and the second channel 14-3 communicates with the second air chamber 14-5. The pressure in the second air chamber 14-5 is at ambient atmospheric pressure.

The pressure in the first air chamber 14-4 on one side of the thrust shaft 11 is equal to the huge pressure in the combustion chamber, and the atmospheric pressure of the second air chamber 14-5 on the other side is higher, so that when the thrust shaft 11 is subjected to the huge thrust force towards the right, the thrust shaft 11 rapidly translates towards the right, and simultaneously drives the ball socket nozzle 6 to rotate towards the left around the nozzle rotating shaft 10.

Similarly, when the right magnet is electrified, the ball socket nozzle 6 can be rotated rightwards. Since the first channel 14-2 and the second channel 14-3 are respectively symmetrical about the gas path control axis 12, i.e. two air chambers in the same orientation of the two thrust shafts 11 are communicated, the motion of the two thrust shafts is completely identical, and the swing of the two ball-and-socket nozzles 6 on the single-shaft swing double-nozzle assembly is always synchronous.

Referring to fig. 1, when the connection line of the two groups of nozzles is on the horizontal plane, the two groups of nozzles can swing up and down in the same direction, and when the two groups of nozzles swing in the same direction, the 4 nozzles deflect in the same direction to control the pitching channel. When the connecting line of the two groups of spray pipes is positioned on a vertical plane, the two groups of spray pipes can swing left and right to control a yaw channel. At any time, the two groups of spray pipes deflect towards opposite directions, so that the projectile body can roll clockwise or anticlockwise, and the rolling channel is controlled. When the connecting lines of the two groups of spray pipes are not positioned on a vertical plane or a horizontal plane, thrust vector control under any flight attitude can be realized by only combining an attitude control algorithm and carrying out combined calculation on pitching, yawing and rolling. The two groups of single-shaft swinging double spray pipes have 4 electromagnets to be controlled, but the electromagnet electrifying states on each group of single-shaft swinging double spray pipes are opposite, each group of single-shaft swinging double spray pipes only needs to determine the electrifying state of one electromagnet, and the electrifying state of the electromagnet on the opposite side is also determined, so that the two pairs of electromagnets are only 0/1-0/1, 0/1-1/0, 1/0-0/1 and 1/0-1/0 in on-off combination, and during actual control, pitching, yawing and rolling control of the projectile body can be realized only by two control channels, and the design difficulty of a control system is greatly reduced.

The application provides a gas driven guided missile swing spray tube is different from the swing spray tube that uses motor drive, and is lower to the requirement of power, only needs to insert standard missile-borne power and makes the operation that the work of electro-magnet can control whole swing spray tube. This application introduces the engine gas as swing spray tube control power supply, and control torque is far greater than general electric machine control torque, effectively improves the wobbling frequency of spray tube, and the delay condition of consequently controlling can be improved, and when the powder charge burning ended, the control power supply also disappeared simultaneously, does not have the extravagant phenomenon of energy. Simultaneously, this application adopts concatenation formula symmetrical design, with the different short sections of inside gas circuit passageway split, the part simple structure after the split for the processing production degree of difficulty greatly reduced reduces manufacturing cost. The air path control shaft is designed with three symmetrical concave sections to realize the control of the combination of 5 paths of channels, the total displacement of the air path control shaft is only 2mm, the control is quick and effective, secondary boring of a center hole of the center seat is not needed, the processing procedures are reduced, and the control method is simple and effective.

The above-described embodiments of the present application do not limit the scope of the present application.
