Description

Technical Field

[0001] This involves the field of shipbuilding and marine engineering experiments, specifically a method for controlling underwater explosion pulsating bubble loads based on delayed explosions. Background Technology

[0002] Underwater explosions are common in shipbuilding and marine military engineering. After an explosive charge detonates underwater, it generates shock wave loads and pulsating bubble loads on nearby structures. The low-frequency hysteresis flow formed by the pulsating bubbles during the underwater explosion, along with the pulsating bubble loads, can cause severe overall damage to large structures. When the bubble pulsation frequency matches the ship's natural frequency, it can also induce a whiplash effect in the hull structure, further intensifying the damage to large structures. Shock wave loads, due to their large peak value and short duration, often cause localized damage to structures and are unlikely to deliver a fatal blow to large structures. Previous experimental studies have found that the shock wave energy of a traditional underwater explosive charge explosion accounts for approximately half of the total energy.

[0003] When overall damage to underwater structures is required, the pulsating bubble load is often much more important than the shock wave. Reducing the shock wave energy of an underwater explosion while increasing the energy of the pulsating bubble is an effective way to improve the overall damage capability of an underwater explosion. When it is necessary to reduce the overall damage caused by the pulsating bubbles of an underwater explosion, interfering with the low-frequency pulsation process of the pulsating bubble or weakening the collapse intensity of the pulsating bubble is an effective way to reduce the overall damage capability of an underwater explosion.

[0004] A patent application titled "A Protective Device and Method for Resisting Underwater Explosion Bubble Loads on Ships" (application number: CN202010295476.8), published on April 2, 2021, discloses a protective device and method for ships against underwater explosion bubble loads, belonging to the field of ship protection. It solves the problem of damage to ships caused by bubble loads. It includes a gas compressor, gas pipelines, and a gas chamber. The gas compressor is connected to the gas chamber via the gas pipelines. The gas chamber is equipped with jet nozzles and is connected to the outside of the ship via these nozzles. The gas chamber includes an inner wall and an outer wall, which are connected to each other. The outer wall has jet nozzles that deliver gas to the outside of the ship. The gas chamber also includes multiple bulkheads, each connected to both the inner and outer walls of the gas chamber. These bulkheads divide the gas chamber into several gas chambers. Each gas chamber has a corresponding jet nozzle on its outer wall. The gas compressor is connected to each of these gas chambers via gas pipelines. It is mainly used for ship protection.

[0005] The text mentions a method for controlling the pulsating load of exploding bubbles, but this method has strict positional requirements. The jet nozzle must be directly facing the underwater exploding bubble in order to deliver gas into the bubble, reduce the pressure difference between the bubble and the surrounding flow field, and thus weaken the bubble pulsating load. Furthermore, according to this method, it does not contribute to enhancing the bubble pulsating load.

[0006] Therefore, there is a lack of existing technologies that can flexibly control the load of underwater explosion-induced pulsating bubbles. Summary of the Invention

[0042] Compared with the prior art, the advantages of the present invention are:

[0043] The underwater explosive pulsating bubble load reduction and enhancement method provided by this invention has a wide range of applications. It can flexibly reduce or enhance the underwater explosive pulsating bubble load according to actual military or engineering needs. When our structures are attacked by enemy underwater weapons, facing underwater pulsating bubbles that pose a total damage threat, the pulsating load of the bubble can be weakened by injecting explosives into the bubble. Compared with the traditional method of simply strengthening the structure itself, this proposes a new protection approach, which is of great significance to the research on ship explosion protection. When launching an underwater explosive attack on an enemy structure, in order to improve the overall damage capability of the weapon, the internal pressure of the underwater explosive pulsating bubble is continuously increased by delaying the detonation, reducing the dissipation of the energy of the sub-charge shock wave, improving the energy utilization rate of the explosive, and thus strengthening the underwater explosive pulsating bubble load to achieve a stronger overall damage effect. This is of great significance to the research of new high-efficiency damage weapons.

[0044] It is suitable for controlling the load strength of underwater explosion pulsating bubbles, thereby enhancing or weakening the destructive power of underwater explosion pulsating bubbles near structures. Attached Figure Description

[0048] To make the advantages and benefits of the technical solution provided by the present invention clearer, the technical solution provided by the present invention will now be described in further detail with reference to the accompanying drawings, specifically:

[0049] Implementation Method 1: Combination Figure 1 and 2 This embodiment describes a method for reducing and enhancing the load of underwater explosion-induced pulsating bubbles, including:

[0050] The step of detonating the first explosive charge within the bubbles generated by the explosion.

[0051] Specifically, it also includes a system for the underwater explosion pulsating bubble load control method, the system being used to implement the underwater explosion pulsating bubble load control method;

[0052] The system includes a controller 3 and a sub-charge 2. The controller is used to collect the explosion parameters of the underwater explosion, obtain the parameters of the bubble 1 generated by the underwater explosion based on the explosion parameters, estimate the detonation time of the sub-charge 1 based on the bubble parameters, and detonate the sub-charge 1 at a specific time to enhance or weaken the impact load of the bubble generated by the underwater explosion.

[0053] There can be multiple sub-packets, which are detonated sequentially at specific times.

[0054] Specifically:

[0055] The method is based on theories such as bubble dynamics, multi-bubble theory, air-burst theory, and interface instability. It can determine the number of subsequent detonation charges, the detonation time interval, and the detonation location based on the need to reduce or enhance the load of pulsating bubbles and the physical information of pulsating bubbles in the flow field.

[0056] Based on delayed explosion, given the parameters of the explosive charge that causes the first underwater explosion, the bubble parameters can be obtained directly from these parameters.

[0057] To reduce the load of bubble pulsation, detonate the first sub-charge when the bubble grows to its maximum volume.

[0058] In the absence of known parameters of the explosive charge that causes the first underwater explosion, the sub-charge can be detonated at the moment when the volume of the bubble reaches its maximum, based on the estimated bubble parameters of the detected explosive.

[0059] The technical solution provided by this embodiment is: to detonate a sub-charge inside the bubble generated by an existing explosion in order to regulate the bubble pulsation load;

[0060] This allows for different detonations at different times to achieve different regulatory effects.

[0061] Figure 2 The "sub-patch 1" and "sub-patch 2" in the diagram are "sub-patch one" and "sub-patch two" in this scheme. To distinguish them from the labels in the attached diagram, the Arabic numerals have been replaced with text.

[0062] The explosion in the plan can be obtained from the known master charge.

[0063] Implementation Method 2: This implementation method provides a method for reducing the load of pulsating bubbles during underwater explosions, characterized by comprising:

[0064] Step 1: Collect the parameters of the underwater explosion;

[0065] Step 2: Based on the parameters, determine the moment when the volume of the bubbles generated by the underwater explosion reaches its maximum value;

[0066] Step 3: Send detonation signal one at the specified time.

[0067] The first detonation signal is used to detonate the first sub-charge inside the bubble generated by the explosion.

[0068] Specifically, given the parameters of the explosive charge, the moment when the volume of the bubbles generated by the underwater explosion reaches its maximum can be determined by:

[0069]

[0070] We obtain, where R m Let ρ1 be the maximum radius of the bubble, ρ1 be the fluid density, and P1 be the ambient pressure at infinity at the same horizontal position as the bubble center, where:

[0071]

[0072] Where W1 is the charge amount and H1 is the water depth;

[0073] Knowing the amount of medicine in a given medicine packet allows us to predict when the bubbles will reach their maximum volume.

[0074] Implementation Method 3: This implementation method further defines the underwater explosion pulsating bubble load reduction method provided in Implementation Method 2. The method further includes:

[0075] Step 4: After the stated time, send detonation signal two.

[0076] Specifically, the second detonation signal is used to detonate the second sub-charge inside the bubble after the first sub-charge explodes; the second sub-charge is an air explosion.

[0077] Implementation Method Four: This implementation method further defines the underwater explosion pulsating bubble load reduction method provided in Implementation Method Three. The method further includes:

[0078] Step 5: Send detonation signal X, which is sent after the previous detonation signal.

[0079] Specifically, there can be multiple sub-charges, with each subsequent sub-charge detonating after the previous one has exploded. All of these are air-explosions, which further reduce the pressure difference between the bubble and the surrounding flow field, thereby weakening the bubble pulsation load.

[0080] Implementation Method 5: This implementation method further defines the underwater explosion pulsating bubble load reduction method provided in Implementation Method 2. Step 3 further includes step 31: sending a transmission signal before sending the first detonation signal.

[0081] This embodiment provides a specific implementation method: a transmission signal is used to send the first sub-charge package into the interior of the bubble. After the first sub-charge package is sent into the interior of the bubble, it is detonated to achieve the effect of detonating the first sub-charge package inside the bubble.

[0082] Implementation Method Six: This implementation method provides an underwater explosion pulsating bubble load reduction controller, characterized in that the controller includes:

[0083] Module 1: Used to collect parameters of the underwater explosion;

[0084] Module 2: Used to determine the moment when the volume of the bubbles generated by the underwater explosion reaches its maximum value based on the parameters;

[0085] Module 3: Used to send a detonation signal to the detonation module at the stated time;

[0086] The detonation module is used to respond to the detonation signal and detonate the explosive charge.

[0087] Specifically, module 1 is used to collect data, module 2 is used to process data, and module 3 is used to send detonation signal 1 based on the data processing results. The detonation module responds to detonation signal 1 to detonate the sub-charge.

[0088] Implementation Method Seven: This implementation method is a further limitation of the underwater explosion pulsating bubble load reduction controller provided in Implementation Method Six. The module 3 further includes: a sub-module: used to send a transmission signal to the transmission module before sending the detonation signal one;

[0089] The launching module is used to respond to the launching signal and launch the first sub-powder packet into the bubble.

[0090] The launching module is a launching device that, upon responding to a launching signal, launches the first sub-powder packet into the bubble.

[0091] Specifically, when an underwater structure is attacked by underwater weapons such as torpedoes, to reduce the load of the underwater explosion's pulsating bubble, the explosive yield can be estimated based on the type of underwater weapon detected by radar and existing weapon databases, thus obtaining the explosion parameters. This can be achieved through:

[0092]

[0093] The moment of maximum volume of the pulsating bubble is estimated, where W is the explosive yield, H is the water depth at explosion, ρ is the water density, and P is the ambient pressure. After a time interval Δt≈T, sub-charge one is detonated. Sub-charge one can be deployed into the pulsating bubble by means of missiles or torpedoes. If there is a need for subsequent detonations, charges can be continuously detonated up to charge n.

[0094] This control method can increase the internal pressure of the bubble to balance the environmental pressure, interfere with the natural frequency of the pulsating bubble, weaken the collapse intensity of the bubble, and thus reduce the load of the underwater explosive pulsating bubble.

[0095] Implementation Method Eight: This implementation method provides a method for enhancing the load of underwater explosion-induced pulsating bubbles, including:

[0096] Step 1: Collect the parameters of the underwater explosion;

[0097] Step 2: Based on the parameters, determine the moment when the bubbles generated by the underwater explosion have a complete bubble-water-gas interface;

[0098] Step 3: Send detonation signal one at the specified time.

[0099] Specifically, the detonation signal sent is used to detonate the first sub-charge inside the bubble generated by the explosion.

[0100] Specifically, when the pulsating bubbles grow to a certain volume, have a complete bubble-water-air interface, and the first sub-packet is completely enclosed in the bubbles, the first sub-packet can be detonated.

[0101] The specific timing for detonating the first explosive charge was determined by:

[0102] Δt1∈(0.05T2,0.5T2),

[0103] Received, among which

[0104] Where R n Let ρ2 be the maximum radius of the bubble, ρ2 be the fluid density, and P2 be the ambient pressure at infinity at the same horizontal position as the bubble center, where:

[0105]

[0106] Where W2 is the charge amount and H2 is the water depth.

[0107] By utilizing the high impedance ratio of the water-air interface of the pulsating bubble, the energy dissipation of the shock wave when the sub-charge explodes together is reduced, and the shock wave energy is converted into the expansion energy of the pulsating bubble to a certain extent. This allows most of the energy of the sub-charge to be effectively converted into the energy of the pulsating bubble, increasing the maximum radius of the pulsating bubble and enhancing the collapse degree of the pulsating bubble in the underwater explosion. This, in turn, enhances the load of the pulsating bubble in the underwater explosion and achieves a stronger underwater damage effect.

[0108] Implementation Method Nine: This implementation method further defines the underwater explosion pulsating bubble load enhancement method provided in Implementation Method Eight, and the method further includes:

[0109] Step 4: After the stated time, send detonation signal two.

[0110] Specifically, the second detonation signal is used to detonate the second sub-charge inside the bubble after the first sub-charge explodes; the second sub-charge is an air explosion.

[0111] Implementation Method Ten: This implementation method further defines the underwater explosion pulsating bubble load enhancement method provided in Implementation Method Nine, and the method further includes:

[0112] Step 5: Send detonation signal X, which is sent after the previous detonation signal.

[0113] Specifically, there can be multiple sub-charges, with each subsequent sub-charge detonating after the previous one explodes, in order to further increase the pressure inside the bubble;

[0114] Specifically, the detonation time for all sub-charges should be:

[0115] Δtx∈(0.05T2,0.5T2),

[0116] Internal detonation, among which

[0117] Where R n Let ρ2 be the maximum radius of the bubble, ρ2 be the fluid density, and P2 be the ambient pressure at infinity at the same horizontal position as the bubble center, where:

[0118]

[0119] Where W2 is the charge amount and H2 is the water depth.

[0120] Implementation Method Eleven: This implementation method further defines the underwater explosion pulsating bubble load enhancement method provided in Implementation Method Eight. Step 3 further includes step 31: sending a transmission signal before sending the detonation signal one.

[0121] This embodiment provides a specific implementation method: a transmission signal is used to send the first sub-charge package into the interior of the bubble. After the first sub-charge package is sent into the interior of the bubble, it is detonated to achieve the effect of detonating the first sub-charge package inside the bubble.

[0122] Meanwhile, underwater explosions can be achieved by detonating a pre-set main explosive charge.

[0123] Specifically, given the parameters of the explosive charge, the moment when the volume of the bubbles generated by the underwater explosion reaches its maximum can be determined by:

[0124]

[0125] We obtain, where R m Let ρ1 be the maximum radius of the bubble, ρ1 be the fluid density, and P1 be the ambient pressure at infinity at the same horizontal position as the bubble center, where:

[0126]

[0127] Where W1 is the charge amount and H1 is the water depth;

[0128] Knowing the amount of medicine in a given medicine packet allows us to predict when the bubbles will reach their maximum volume.

[0129] Implementation Method Twelve: This implementation method provides an underwater explosion pulsating bubble load enhancement controller, the controller comprising:

[0130] Module 1: Used to collect parameters of the underwater explosion;

[0131] Module 2: Used to determine, based on the parameters, the moment when the bubbles generated by the underwater explosion grow to a certain volume and have a complete bubble-water-gas interface;

[0132] Module 3: Used to send a detonation signal to the detonation module at the stated time;

[0133] The detonation module is used to respond to the detonation signal and detonate the explosive charge.

[0134] Specifically, module 1 is used to collect data, module 2 is used to process data, and module 3 is used to send detonation signal 1 based on the data processing results. The detonation module responds to detonation signal 1 to detonate the sub-charge.

The module 3 further includes: a sub-module: used to send a transmission signal to the transmission module before sending the detonation signal one;
