Background
In order to improve the stealth performance of ships, realize integration and modularization of weapon equipment and control, systemization of weapon maintenance, and the adoption of a vertical emission system for an anti-air and anti-ship weapon is the mainstream of medium-large water surface ship weapon equipment.

At present, the method for throwing the near-distance throwing load of the ship-borne vertical launching comprises the following steps: after the load is launched out of the vertical launch canister, a thrust engine (such as a rocket engine, a turbojet engine and the like) positioned at the tail of the load drives the load to continuously rise, and a posture adjustment device (such as a rudder wing, a vector nozzle and the like) rapidly moves to adjust the pitching posture angle of the load, so that the speed of the load in the vertical direction is converted into the horizontal direction (in some cases, the adjustment of the pitching posture intersection can also cause the load to rapidly move to the horizontal plane), so as to realize the near motion of a specific track.
However, the method for realizing close-range load delivery by adopting the thrust engine and the attitude adjusting device is limited by the characteristics of the load motion trail, and the response time of delivering the load to a specific area is long; in order to achieve as much as possible the launch of the load into the specific area, it is necessary that the attitude adjustment device provides as much rotational torque as possible; and the improvement of the rotation moment of the gesture adjusting device brings great requirements to the structural strength and the functional performance of the gesture adjusting device. In addition, due to the nature of the close range launch load configuration, it may not be possible to maneuver quickly over load, and therefore there is also a need to limit the launch speed of the load.

Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
The embodiment of the specification provides a near-distance release method for ship-based treatment of a transmission load, which is used for realizing quick near-distance release of a vertical transmission load with a specific purpose.
Fig. 1 is a schematic structural diagram of a ship-borne vertical transmission load provided by an embodiment. As shown in fig. 1, the load 11 in this embodiment comprises a transverse thrust device 12; the lateral thrust device 12 is a backflushing jet device with its jet perpendicular to the vertical extension of the load 11 (that is, in the case of a vertical arrangement of the load 11, the jet of the backflushing jet device is arranged in the horizontal direction). The transverse thrust means 12 are operative to apply thrust in the horizontal direction towards the load 11. In the present embodiment, the number of spouts and the positions of the spouts in the lateral thrust device are not limited as long as the lateral thrust device 12 can apply a thrust force to the load 11 that translates the load 11.
Fig. 2 is a flowchart of a close-range delivery method of a ship-borne vertical transmission load provided by an embodiment. As shown in fig. 2, the close-range delivery method provided in this embodiment includes steps S101-S102.
S101: the load is caused to leave the vertical launch canister in a vertical launch manner.
In step S101, the load may be moved away from the emission cylinder by cold emission or may be moved away from the vertical emission cylinder by heat emission, and the embodiment is not particularly limited.
Under the condition of adopting a cold emission mode for emission, the vertical emission system generates high-temperature and high-pressure gas to be filled into the emission cylinder from the bottom, and the inside of the emission cylinder starts to be pressurized so that the pressure acts on the bottom of a load; when the acting force generated by the pressure in the launching tube is larger than the gravity of the load, the load is gradually accelerated in the vertical direction and leaves the vertical launching tube at a certain speed.
In the case of thermal launch, the booster engine at the lower end (i.e., the tail end) of the load fires against the weight of the load, causing the load to leave the vertical launch barrel.
In practical application, the load can be ensured to have enough initial speed after leaving the vertical transmitting cylinder, and the cold transmitting mode can be adopted to ensure that the load can obtain the enough initial speed, and the design complexity of the load can be simplified, so that the load is preferably transmitted in a cold transmitting mode in the specific application of the embodiment.
S102: after the load leaves the vertical launch canister, the transverse thrust means is activated so that the load attains a horizontal velocity and moves towards the launch area.
The vertical launch canister does not laterally confine the load after the load leaves the vertical launch canister. At this time, after the transverse thrust device is started, the recoil nozzle in the transverse thrust device ejects jet flow, so that the load obtains thrust, and the thrust enables the load to obtain acceleration in the horizontal direction. Because the acceleration in the horizontal direction is obtained, the load obtains the horizontal movement speed. It is conceivable that the load is now moved towards the launch area (i.e. the area remote from the vessel) under the combined action of gravity and thrust.
It is conceivable to use the aforementioned method of close-range delivery of the vertical launch load, and determine the dead time of the load in the event that the load leaves the vertical launch canister and no longer applies a lifting thrust thereto; in the case where the start timing of the lateral thrust device after leaving the vertical launch canister with respect to the load is determined and the thrust characteristics of the lateral thrust device are known, the final launch area of the load can be determined.
In the reverse consideration, when the index of the close-range delivery area of the load is fixed, the thrust characteristic of the load in the vertical launching tube and the thrust characteristic of the transverse thrust device can be designed according to the index, so that the load can be delivered to the close-range delivery area.
The method in the steps S101-S102 is re-analyzed, the transverse thrust device is started to enable the load to directly move towards the near-ground throwing area in the transverse movement process, and the load does not need to be turned by adopting a large overload rapid maneuvering method to realize the movement direction change and thrown into the near-ground area as in the prior art, so that the transverse acceleration applied to the load can be set to be smaller without setting a gesture adjusting device with harsh technical indexes; because the load is subjected to smaller lateral acceleration without being subjected to larger maneuvering overload as in the prior art, the stress index of other devices in the load can be relatively reduced.
In addition, because the transverse thrust device directly enables the load to move towards the near-ground throwing area, the load can quickly reach the near-ground throwing area under the condition of ensuring the transverse movement of the load; compared with the existing load close-range delivery method, the delivery method provided by the embodiment reduces the response time of the load to the close-ground delivery area and improves the delivery and deployment speed of the load carrying load.
Fig. 3 is a schematic diagram of the trajectory after load emission provided by the embodiment. As shown in fig. 3, the load moves in a vertical direction during the firing phase; and the load moves in a parabolic trajectory after actuation of the transverse thrust means.
The following describes specific design criteria of the transverse thrust device based on certain deterministic performance requirement criteria. Assume that the determined performance index includes t Transverse direction And L Short distance Wherein t is Transverse direction For the time from the start of the load from the transverse thrust means to the load reaching the near-ground launch area, L Short distance Representing the distance of the near-ground launch area to the vessel.
Assuming stable operation of the transverse thrust device, the formula is adopted
And +.>
It can be determined that the minimum thrust of the transverse thrust device to achieve the performance index is +.>
F can be determined from the maximum lateral overload that can be borne by the load Transverse (Max) ＝n Limiting ×m Load of Xg, where n Limiting Represents the maximum normal overload value bearable by the vertical launching load of the ship, g represents the gravity acceleration value, F Transverse (Min) ≤F Transverse (design) ≤F Transverse (Max) 。
In specific applications, the transverse thrust devices are mostly power devices with high power ratios such as rocket engines. The rocket engine generates high-temperature flame which is transversely sprayed when the rocket engine is at high temperature, and the transverse high-temperature flame can damage the superstructure of the naval vessel, so that the ignition time of the recoil thrust device in practical application is limited by the load throwing direction and the superstructure of the naval vessel.
If the load is required to be put in the lateral direction perpendicular to the ship keel, because of the structural design characteristic of the ship, the ship keel is vertical, the superstructure is not left, and flames generated by the recoil thrust device cannot affect the ship superstructure, so that the recoil thrust device can be started after leaving the vertical transmitting cylinder.
If the load needs to be put in the area in front of the side or behind the side of the ship, in order to protect the ship superstructure from being influenced by the recoil thrust device, the transverse thrust device is started again after the load leaves the vertical transmitting cylinder and rises to a safe height. In a specific application, the safety height can be the mast height, bridge height or the height of the furnace cabin radiator of the ship according to the position where the load is deployed.
The following analysis of the speed characteristics of the load as it leaves the launch canister is required to enable the load to meet the aforementioned performance requirements under safe height constraints. Through the fieldThe scene analysis shows that the load moves at least to a safe height h Secure The ignition safety of the transverse thrust device can be ensured. Then according to the force analysis, in order to make the load rise to the safe height, the required speed obtained by the emission from the vertical emission cylinder is
In addition, in practical application, in order to enable the load to be at a level approximately similar to that of the ship when reaching the delivery area, and simultaneously ensure that the vertical speed of the load is not excessive after reaching the delivery area, the maximum height h of the load after being emitted from the vertical emission cylinder is required to be limited max According to the force analysis
Thus, it is possible to obtain
Thus, according to v Discharging cylinder The driving force characteristic of the vertical emission phase acting on the load can be determined.
In practical application, the dynamic characteristic of the load in the vertical direction and the force-bearing movement characteristic in the horizontal direction are required to be combined, so that the load can be put into a set putting area. In a specific application of this embodiment, the load is applied in a horizontal direction with a specific model, and the thrust force applied to the load is determined, so that steps S201-S203 may be used to determine the operating characteristics of the cold emission device.
S201: and determining the distance of the put-in area relative to the ship.
S202: the initial speed of the load leaving the vertical launch canister is determined based on the distance and the thrust of the lateral thrust device.
In step S202, according to the distance and the thrust of the lateral thrust device, the time t from the start of the lateral power device to the movement of the load to the launch area can be determined Transverse direction The method comprises the steps of carrying out a first treatment on the surface of the To enable the load to move to the launch areaAt t Transverse direction In this, the load should be in a dead space state. According to the above-mentioned required dead time t, the greater the initial speed of the load leaving the launch barrel is, the greater the dead time is Transverse direction The minimum initial velocity of the load off the vertical launch canister may be determined, and a reasonable initial velocity may be selected within a range greater than the minimum initial velocity.
S203: an operating characteristic of the cold emitting device within the vertical emission barrel is determined based on the initial velocity and the weight of the load.
The working characteristics of the cold-emitting device are analyzed below under the special constraint that the transverse thrust device is started when the load rises to the highest level and the horizontal level of the load reaches the delivery area and is identical to the level of the load when the load leaves the vertical-emitting cylinder, at the moment a Transverse direction It has been determined.
According to
Can determine +.>
Because the transverse thrust device is started when the vertical speed of the load is 0, the speed of the load reaching the throwing area can be determined to be the same as the cylinder outlet speed of the load, and the direction is opposite, and the load reaches the throwing area>
According to v Discharging cylinder The operating characteristics of the cold-emitting device in the vertical emission cylinder can be determined such that the carrier reaches v when leaving the vertical emission cylinder Discharging cylinder 。
Of course, the safety height h may also need to be considered during the execution of steps S201-S203 Secure And the load may start when the vertical speed is not reduced to 0, and corresponding v can be obtained by adding corresponding constraint conditions Discharging cylinder The method comprises the steps of carrying out a first treatment on the surface of the In addition, in practical application, the thrust characteristic of the transverse thrust device can be determined by comprehensively considering various constraint conditions, and the speed v of the load leaving the vertical transmitting cylinder Discharging cylinder So that the load is transmitted fromInitially, the drop zone is reached in a reasonably short time.
In the specific application of the embodiment, the load is transmitted by the control quantity calculated by the previous calculation and v is influenced by the actual battlefield environment and the working characteristics of the cold transmitting device Discharging cylinder The theoretical calculation is not reached, in which case the load may not be moved to the preset drop zone. To solve this problem, the load bottom in this embodiment may also be provided with a vertical thrust device. In step S102, the transverse thrust device load is started to obtain a horizontal speed, and in the process of moving to the launch area, steps S301-S303 can be executed to ensure that the load can finally reach the launch area. .
S301: the current height of the load is determined.
In this embodiment, an altimeter may be disposed in the load to measure the altitude of the load and determine the current altitude of the load relative to the water surface based on the altitude. In other embodiments, the current height of the load can be determined according to optical signal calculation by adopting a ship optical monitoring mode.
S302: and determining whether the load can fly to the throwing area according to the current height, the horizontal distance between the throwing area and the current position, the transverse speed state of the load and the transverse thrust exerted on the load by the transverse thrust device.
If step S302 determines that the load cannot fly to the launch area, step S303 is performed.
Step S302, calculating future running tracks of the load according to the horizontal distance between the throwing area and the current position, the transverse speed state of the load and the transverse thrust exerted on the load by the transverse thrust device, so as to determine whether the load can fly to the throwing area. In performing this, it is assumed that the transverse thrust device is always working properly. If the load cannot fly to the distance of the throwing area, the load height can be determined to be too low, and the dead time of the future load cannot meet the requirement.
S303: and controlling the vertical thrust device to apply vertical thrust to the load.
And controlling the vertical thrust applied by the thrust device to the load, and determining the horizontal distance from the throwing area to the current position, the transverse speed state of the load and the transverse thrust applied by the transverse thrust device to the load according to the current height.
It is conceivable that in the case of a vertical thrust exerted by the vertical thrust device, the vertical thrust can overcome the action of gravity to which at least part of the load is subjected, and consequently reduce the acceleration of the load in the vertical direction, and consequently increase the load dead time; by increasing the dead time of the load, the load can be ensured to move a larger distance in the transverse direction, and the preset throwing area can be reached as much as possible.
In practical application, the vertical thrust device can be various recoil thrust devices; the vertical thrust device is preferably a high-pressure compressed air source or the like in view of simplicity of practical structural design.
The transverse thrust device in the embodiment is used for enabling the load to obtain horizontal thrust when working; however, in practical application, the load is affected by ship shaking, uneven vertical thrust and the like in the vertical launching process, and the problem of inclination possibly occurs after the load leaves the vertical launching tube, and at the moment, if the horizontal thrust device still applies horizontal thrust to the load, the horizontal thrust can act on the load to form a rotation moment, so that the load rotates uncontrollably. In addition, the load may also rotate after the load is launched under the influence of various disturbances. The load rotates to realize the throwing of the load in the throwing area.
In order to solve the foregoing problem, in the present embodiment, an acceleration measuring device is further included in the load; in practical application, the acceleration measuring device can be a gyroscope or a three-coordinate accelerometer processed by the MEMS technology. The foregoing delivery method further includes steps S401 to S402.
S401: the rotational angular velocity of the load is measured from the acceleration measuring device.
S402: the injection angle of the transverse thrust means is adjusted according to the moment of inertia to avoid rotation of the load.
Assuming that the distance from the rotating shaft of the transverse power device to the load center is D, the load or disturbance after the emission causesThe moment of inertia of the load rotating around the rotating shaft is I yy The angular speed of the load rotating around the axial direction is phi, and the transverse power device rotates around the deflection shaft by an angle
In this embodiment, in order to realize that the load can be thrown to all directions of the naval vessel according to the requirement, and reduce the number of the lateral thrust devices configured in the load, the load transmitting system further includes a rotating device, where the rotating device is used to change the injection direction of the lateral thrust devices.
The rotation device may be installed in the vertical transmission cylinder or may be installed on the load, and the present specification is not particularly limited. In order to reduce the design difficulty of the load as much as possible, the rotation means are preferably arranged in the vertical transmission drum.
In the case of setting the aforementioned rotating device, the close-range delivery method further includes: determining the throwing direction of the load; before the transverse thrust device is started, the rotation device is driven to rotate according to the throwing direction of the load, so that the nozzle of the transverse thrust device faces in the direction opposite to the projection direction.
