2. Description of Related Art

[0002 Since the invention of the V-i rocket by Nazi -Germ any in WW1I, the possibility of a long-range attack from the safety of one's own country has been a reality likewise, the threat of a long-range attack with little possibility of retribution has been a looming threat to all nations since then. To combat the terror of long-range rockets/missiies/sheils, defense systems ave been developed to intercept said attacks.

[0003] However, the days where JCBMs (Inter-Continental Ballistic Missiles) arid other long-range missiles were the main threat to a nation are gone, in large part due to the defenses and long-range detection systems that are currently w place. Furthermore, the time it takes to fire iong-range missiles ranges from dozens of minutes to hours, before the weapon can deliver its ordinance, giving the target ample time to respond The main threat to nations has become the short-range missiles, rockets and shells that can deliver their explosive ordinance within minutes or seconds of being launched [0004] Current defense systems ate unable to intercept all the incoming hostile objects when hundreds or thousands of short-range missiles/rockets or shells are launched in a small window of time, at a small area

[0005] Bence, an improved systems and methods as described in this application are still a long felt need.

[0016] The following description is provided, alongside ail chapters of the present invention, so as to enable any person skilled in the an to make use of said invention and sets forth the best modes contemplated by the inventor of carrying out this invention. Various modifi cations, however, will remain apparent to those skilled lit the art, since the generic principles of the present invention have been defined specifically to provide a means and method for stationary radar controlled and fluid cooled high speed gun array defense.

[00171 In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present invention. However, those skilled in the art will understand that such embodiments may he practiced without these specific details lust as each feature recalls the entirety, so may it yield the remainder. And ultimately when the features manifest, so an entirely new feature he recalled Reference throughout this specification to“one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described m connection with the embodiment is included in at least one embodiment of the invention

[00181 The phrases "at least one", "one or more", and "and/or" are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions "at least one of A , B and C", "at least one of A, B, or C", "one or more of A, B, and C", "one or more of A, B, or C" and "A, B, and/or C“ means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.

[0019] The term ' lurality* refers hereinafter to any positive integer (e g, 1 ,5, or 10).

[0020] Generally speaking, the system and method may allow creating and using a defense system against multi-missile, rocket and shell attack. Particularly, this invention describes a combined use of radar, a computing system and fluid cooled gun constructed in redundant arrays to detect and destroy hostile rnissiles/rockets/shells in mid-flight. More particularly, the gun arrays may make use of timer-detonating shells to intercept the hostile elements The guns m the arrays make use of a controlled fluid cooling system to prevent overheating, allowing the guns to sustain rapid fire over a long period of time, which would be important against simultaneous massive and condensed attack using missile/rocket/shell attack.

[0021] In a preferred embodiment of the invention, several stationary gun arrays may be positioned in strategic areas. Such stationary gun arrays may be controlled by a computing device which is data fed by a radar subsystem and may manage and assess incoming threats (such as hostile elements), so as to achieve a high hit rate and hopefully prevent the hostile elements from achieving their goals. The stationary gun arrays may be positioned so that rockets, missiles or shells that survive a first gun array, may be hit by the next array. As can be appreciated, the number of arrays, their size and the size of the guns in them may be determined by a threat assessment that evaluates the most likely number and type of rockets, missiles or shells that the arrays ight have to engage

[0022] The guns may use timer controlled shells to engage hostile missiles, rockets and shells. The guns may make use of high accuracy targeting data acquired from a radar and computing device in order to determine an intercept location. The radar and computing device may be designed to detect hostile elements as well as predict the hostile element’s movements. Based on such data, an intercept location may he calculated and estimated, as well as detonation timing This data may then then be fed to the guns the relevant gun arrays. The data represents as precise as technologically possible calculations as to the shooting angle and distance to the intercept location in order to program the shells to detonate at a precise point in space allowing tor the most possible effective interception of hostile element.

[0023] High speed guns are subject to overheating. Therefore, the guns m the gun arrays may be equipped with a fluid cooling system that may enable a high rate of fice without overheating. The high rate of fire may allow for better interception of incoming hostile rockets, missiles and shells.

[0024] The gun arrays may make use of cost effective shells. Each gun may have a feeding mechanism that may enable fast and continuous shooting in order to achieve a sufficient engagement- and high hit rate. By using shells as opposed to missiles or rockets the cost of intercepting a hostile object rnay be reduced immensely.

[0025] The shells may be timer detonated (with the timers determined by the computing device) and may have an independent built-in safety mechanism to prevent the danger of a defense system becoming accidental artillery.

[0026] In some embodiment of the invention, the system may react in proportion to the threat. For example, in case of a large-scale attack, the entire gun array system may function as an integrated unit. While in case of a Singular or small-scale attack each gun (or part of the gun array) may act independently.

I, Stationary fluid cooled gun arrays

[0027] One of the elements of the system is the gun array The gun array may be a collection of one or more guns, cannons, etc (hereinafter will collectively be referred as‘gun ⁵ or‘guns ⁵ ). The guns may have a fluid cooling means, be computer and radar controlled and may, in some embodiments of the invention,, rely on low cost ammunition to intercept and destroy hostile elements.

[0028] In further embodiments of the invention, several gun arrays may be arranged in several defense lines or areas in order to increase the hit rate against enemy rockets, missiles or shells litis means that if some a hostile element is not intercepted by a first gun array the second or third gun array may be engaged to intercept the hostile elements. [00291 The number of guns in each array may be determined by the threat-level and the desired hit rate Areas of strategic value and the areas with a high risk of being hit by hostile elements might warrant an increased number of guns arrays.

[0030] The size or caliber of the guns might be determined as wed by the threat-level, die expected engaged targets and the range of operation. In some specific embodiments of the invention, the guns may be expected to have a standard caliber of 75-85mm. A larger 125-155mm version may also be expected to be of common usage. Currently, some of the standard 75-85mm guns are able to fire once per second, and the larger 125-155mm guns are able to fire every two seconds As the number of guns in each array may be determined by the threat level, one can calculate how many guns will be required for each array. For example, if an enemy has 100,000 short-range rockets that they can launch in the window of 10 minutes, an array, or a set of arrays, in excess of 167 guns might be required to intercept every hostile rocket (167 guns x 1 shell/second x 600 seconds ^:::: 100,200 shells fired to intercept hostile elements).

[0031] In some embodiments of the invention, the inner profile of the gun barrels in the gun arrays may be either rifled or smoothbore depending on the ammunition type and other relevant parameters. Rifled guns may be the prominent due to their simple and cost-effective ammunition, but smoothbore guns with remote-controlled shells may also be with benefits

2, Fluid cooling system

[00321 In most cases, barreled weapons have two fire rates an initial fire rate and a sustained/continuance fire rate, with the sustained fire rate being, in most cases, significantly slower than the initial. This slower fire rate is usually due to overbearing. In order to create a high probability of hitting enemy targets, each gun in the gun arrays may be required to ave fast and continuous fire-rates; even over relatively extended periods of time. In order to combat overheating, a fluid cooling system may be provided to each of the guns. [00331 The cooling system may have several parts: a cooler (e.g. a fan or compressor, etc.), high pressure pumps, a thermal fluid (e.g oil or other fluids), tubes for the fluid and the cooling element on the guns themselves.

[0034] The cooling element on each gun barrel may consist of at least 2 sections, determined by length, diameter and shooting rate of the gun, to ensure that the gun Is kept at an even temperature at all times. A cooling element is depicted in Figure 1. In essence, a cooling section is a pipe that may nave a slightly larger diameter than the external diameter of the barrel. This pipe may be placed around the barrel m such a manner that a small space is created between the barrel and pipe allowing for a relatively free movement of cooling fluid lire pipe and barrel may be kept equidistantly separated along their diameters by the use of, for example, rubber washers or gaskets. The pipe may also include at least 2 holes for the injection and drainage of the cooling fluid. The pine, and other attachments, may have to he made strong enough to resist the high g-fbrces encountered during the firing of a shell .

[0035] Figure 1. depicts an example of a cooling section 100 having inlet and outlet 101 for thermal fluid leading to the cavity 103 around the barrel outer diameter 102

[0036] hi some embodiments of the invention, at least two independent cooling sections may be placed on each barrel: a) around the chamber where initial detonation takes place, and b) at the exit of the barrel. Additional cooling sections along the length of the gun may be added as required. In specific embodiments of the invention, a cooling section may be placed for every 50 crn or so of barrel length, as depicted in Figure 2 which depict multiple coolant sections and gaskets/washers 201 separating the sections. Additionally, every cooling section may he equipped with a regulating thermostat, thermistor, etc ensuring an even temperature along the entire length of the barrel For cost and production efficiency, several cooling sections may make use of the same external pipe, but may still be considered as separate sections due to the placement of the fluid injection and drain pipes, and rubber washers/gaskets. An example of this variation can is depicted in Figure 3

§ [00371 The fluid cooling system may also aid in the precision of the gun. By maintaining a constant temperature, the cooling system prevents some, most or all of the expansion of the metal barrel. This means that every shot made by the gun is made in relatively the exact same environment which results in an increase in accuracy.

Computerized radar system (CRS)

[0038] The guns in the gun arrays may he controlled by a computerized radar system (hereinafter referred to as 'CRS ⁵ ), as depicted in Figure 4. he CRS may detect and manage the entire array, by having an overall picture of every hostile element launched throughout an attack. The CRS may designate each gun in the array with a hostile element and provide the angle of attack and timing so as to intercept it. Once a gun has shot at a target, it can immediately he designated to another target. This means that every gun in the entire array can be effectively engaged with multiple hostile targets at almost the same time, using the principles of ^s Tlre and Forged ⁵ .

[0039] The radar system may be considered as the "eye ^" of the entire system, providing the computer with the number, direction, speed arid location of hostile elements. This information may then be passed to a computing device which may calculates and estimate intercept trajectories for the different guns as depicted in Figures 5, 6 and 7 Tire radar system may be based on electro-magnetic wave detection or heat detection or any other method known m the art.

[0040] In some embodiments of the invention, should the radar system he overwhelmed by a large number of targets, the radar system may change modes Instead of having multiple radars with a 360° field of view, the radar system may designate several segments of the sky for individual radars to watch, so that each radar only watches a fraction of the sky. When added together, all the segments may still give a complete 360° field of view or any other portion of the sky which is relevant to the scenario. [0041 ] Software running on the computing device and controls may be used to perform the calculations, estimations and decisions that are needed to achieve efficiency and a high hit rate from the guns in the gun arrays Amongst the variables that ought be required in order to achieve these calculations are: distance to target, height of target, speed of target, direction of target, impact location, humidity, wind conditions, air temperature, curvature of the earth, other enemy targets etc

[0042] Depending on the scenario, a tew guns may be designated at the same target to create a“spray- like” effect. This is aa alternate fire mode where the detonation locations are relatively close so as to have a larger effect and cover a larger area than a single shell could achieve on its own.

Low cost a unition

[0043] In specific embodiments of the invention, the primary ammunition type used in the system may be a timer controlled shell that may be programmed by the CRS to detonate when it reaches the effective impact point or area in the sky.

[0044] Because the System bears resemblance to artillery, all shells may be equipped with a mechanical or electronic safety mechanism that may ensure that the shell explodes in the sky in the unlikely event that the primary timer fails if the timer should fail once the shell has been fired, the safety mechanism may detonate once the shell falls below a certain height (or other safety method as known in the art). Tins may occur after the shell has reached a maximum height and has started falling again.

[0045] in the event that a hostile target is able to circumvent the defense lines for whatever reason, the system may be required to fire over friendly civilian territory. By utilizing such a safety feature, the system may be able to function effectively in all directions without endangering civilian life., whether hostile or friendly, without the danger of misfires that cause disastrous collateral damage. [0046] The Shells may be loaded into the guns by an automatic shell-feeding system that may ensure that the gun may fire at any time required by the CRS.

[0047] In other embodiments of the invention, remote or radar-controlled ammunition types may be used by the system (smooth-bore guns).

[0048] Although selected embodiments of the present invention have been shown and described, it is to be understood the present invention is not limited to the described embodiments instead, it is to he appreciated that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and the equivalents thereof
