20220128325
Embodiments of the present invention relate generally to systems and methods for stationary radar controlled and fluid cooled high speed gun array defense.
Since the invention of the V-1 rocket by Nazi-Germany in WWII, 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/missiles/shells, defense systems have been developed to intercept said attacks.
However, the days where ICBMs (Inter-Continental Ballistic Missiles) and 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 in place. Furthermore, the time it takes to fire long-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.
Current defense systems are 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.
Hence, an improved systems and methods as described in this application are still a long felt need.

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 missiles/rockets/shells in mid-flight. More particularly, the gun arrays may make use of timer-detonating shells to intercept the hostile elements. The guns in 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.
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 might have to engage.
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 be calculated and estimated, as well as detonation timing. This data may then then be fed to the guns in 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 for the most possible effective interception of hostile element.
High speed guns are subject to overheating. Therefore, the guns in the gun arrays may be equipped with a fluid cooling system that may enable a high rate of fire without overheating. The high rate of fire may allow for better interception of incoming hostile rockets, missiles and shells.
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 may be reduced immensely.
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.
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.
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’ or ‘guns’). 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.
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. This 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.
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.
The size or caliber of the guns might be determined as well by the threat-level, the 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 75-85 mm. A larger 125-155 mm version may also be expected to be of common usage. Currently, some of the standard 75-85 mm guns are able to tire once per second, and the larger 125-155 mm 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×1 shell/second×600 seconds=100,200 shells fired to intercept hostile elements).
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-reflective ammunition, but smoothbore guns with remote-controlled shells may also be with benefits.
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 overheating. In order to create a high probability of hitting enemy targets, each gun in the gun arrays may be required to have 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.
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.
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
In 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 cm or so of barrel length, as depicted in
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.
The guns in the gun arrays may be controlled by a computerized radar system (hereinafter referred to as ‘CRS’), as depicted in
The radar system may be considered as the “eye” of the entire system, providing the computer with the number, direction, speed and 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
In some embodiments of the invention, should the radar system be 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.
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 might 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.
Depending on the scenario, a few guns may be designated at the same target to create a “spray-like” effect. This is an 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
In specific embodiments of the invention, the primary ammunition type used in the system may be a tinier controlled shell that may be programmed by the CRS to detonate when it reaches the effective impact point or area in the sky.
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). This may occur after the shell has reached a maximum height and has started falling again.
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.
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.
In other embodiments of the invention, remote or radar-controlled ammunition types may be used by the system (smooth-bore guns).
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 be 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.
