Abstract
According to various embodiments of this disclosure, an armor system includes a front wall and a back wall spaced apart from one another. The armor system also includes a first plurality of internal walls spaced apart from one another and fixed on one end of each internal wall to the front wall and on the other end of each internal wall to the back wall. The internal walls are slanted (i.e., fixed at angles other than ninety degrees) with respect to the front wall and the back wall. In this manner, a projectile passing directly through the front wall will strike at least one of the slanted internal walls before striking the back wall. Thus, the armor system prevents penetration of an underlying structure (e.g., armored vehicle, housing structure, or other enclosure) that is protected by the armor system.
Description
- The present application claims the benefit of currently co-pending U.S. Provisional Application No. 62/104,516, entitled “BALLISTIC ARMOR,” and filed on Jan. 16, 2015. U.S. Provisional Application No. 62/104,516 is incorporated herein by reference in its entirety.
- In hostile environments, vehicles, marine vessels, aircraft, housing structures, and enclosures are sometimes subject to penetration by projectiles injuring or damaging persons or the contents within. High strength, mass and energy absorbent materials can be used in the manufacture of the outer surface of such vehicles and enclosures, but usually these materials will add significant weight and/or cost to the structure and may only serve to slow down a projectile which may still have sufficient speed and momentum to inflict injury or damage to the persons or contents within. This is particularly the case where armor piercing projectiles are involved.
- According to various embodiments of this disclosure, an armor system is presented which employs the principle of deflection as well as energy absorption to both redirect the path of the projectile and absorb its momentum and energy in multiple instances preventing it from entering the interior of the enclosure. The armor system includes a front wall and a back wall spaced apart from one another and a first plurality of internal walls spaced apart from one another, fixed on one end of each internal wall to the front wall and on the other end of each internal wall to the back wall. The internal walls are slanted (i.e. fixed at angles other than ninety degrees) with respect to the front wall and the back wall. In this manner a projectile striking the outer wall will have some of its energy absorbed by the strength and mass or structural composition of the outer wall. If this does not stop the projectile, it will then strike at least one of the slanted internal walls where it will be deflected, further reducing the speed and momentum of the projectile before it strikes the back wall where it will again be deflected and its path changed by as much as ninety degrees staying within the front and back wall of the armor system, preventing penetration of the interior of the structure or vehicle and injury to the persons or contents within.
- In some embodiments, the armor system further includes a second plurality of internal walls spaced apart from one another and angled with respect to the first internal walls. Each second internal wall is angled with respect to an adjacent first internal wall at an angle of about ninety degrees, though other angles may be appropriate. In some embodiments, each second internal wall extends between adjacent first internal walls. For example, a second internal wall can be fixed on one end to a first one of the first internal walls and on the other end to a neighboring one of the first internal walls. In this manner, a projectile passing directly through the front wall will strike at least one of the first internal walls, at least one of the second internal walls, or both, before striking the back wall.
- In some embodiments, the armor system can be formed from modular armor units. For example, each armor unit can include a front wall portion, a back wall portion, and at least one of the first internal slanted walls (extending from the front wall portion to the back wall portion). In some embodiments, each unit can include a front wall portion, a back wall portion, at least two of the first internal walls (extending from the front wall portion to the back wall portion), and at least one second internal wall (extending from one of the first internal walls to another one of the first internal walls). A top or bottom corner unit of the ballistic armor can also be modular or it can be manufactured as a single structure that has a size and shape allowing it to fit within or receive a modular armor unit at least one end.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
- The Detailed Description is described with reference to the accompanying figures. The use of the same reference numbers in different instances in the description and the figures may indicate similar or identical items.

FIG. 5 is a partial cross-sectional side elevation view illustrating a top corner unit of a ballistic armor system in accordance with an embodiment of the present disclosure. -
FIG. 6 is a partial cross-sectional side elevation view illustrating a top corner unit and a side portion of a ballistic armor system, joined together, in accordance with an embodiment of the present disclosure. - A ballistic armor resists the penetration of projectiles (e.g., bullets and the like) by various means of absorbing the projectile energy. For example, some armors capture a bullet in a net-like material, such as a heavy woven cotton vest and/or a KEVLAR vest; absorb the energy from a bullet with a hard strike face material that spreads the energy of a bullet over a wider area, often absorbing the energy in the fracture of the strike face material; or by a combination of both a hard strike face material and a net-like structure. High strength steel is a material that has a hard strike face but is also malleable, with a high resistance to penetration by a bullet. As a bullet penetrates the steel, energy is absorbed in the steel as it deforms under the pressure of the bullet, slowing the bullet.
- As described herein, deflection can also be used to stop a high energy projectile. For example, when a bullet is traveling at high velocity, the energy required to change its direction is less than the energy required to stop it. When a bullet hits a hard surface at an angle, it is very likely to change its direction or ricochet off the surface at some angle depending on the speed and mass of the bullet and the strength, hardness and angle of the strike face. In doing so, the bullet loses some of its energy. Even where hardened point bullets are used, and the point digs into the strike face surface (e.g., as opposed to ricocheting off the surface), the energy required to deflect an angled shot is generally less than that required to stop a shot normal to the surface of a material.
- This disclosure describes an armor system that leverages projectile energy loss from deflection at multiple angles to stop or slow projectiles such as high energy, hardened projectiles including, but not limited to: bullets, rockets, cannon balls, missiles, and the like. In some implementations, the armor system also includes on one or more of: a hardened strike face, an energy absorbing material (e.g., energy absorbing foam or other core material), an energy absorbing structural configuration (e.g., a net-like or woven structure), or the like.
- Various embodiments of a
ballistic armor system 100 are illustrated inFIGS. 1 through 6 . Theballistic armor system 100 can be implemented in a variety of settings. For example, theballistic armor system 100 can be used for armored vehicles (e.g., ground vehicles, marine vessels, aircrafts, and the like), housing structures (e.g., dwellings, buildings, storage units, etc.), and other enclosures (e.g., enclosures for electronics, supplies, or sensitive materials such as oxygen, fuel, water, and the like), and may even be used for body armor. In some implementations, theballistic armor system 100 is placed over walls or other surfaces being protected. In other implementations, theballistic armor system 100 is used to manufacture the protected walls or surfaces. For example, the protected wall or surface can comprise theballistic armor system 100. - The
ballistic armor system 100 includes afront wall 104 and aback wall 102 spaced apart from one another. Thearmor system 100 also includes a first plurality ofinternal walls 106 spaced apart from one another and fixed on one end of eachinternal wall 106 to thefront wall 104 and on the other end of eachinternal wall 106 to theback 102 wall. Theinternal walls 106 are slanted (i.e., fixed at angles other than ninety degrees) with respect to thefront wall 104 and theback wall 102. A projectile passing directly through thefront wall 104 will strike at least one of the slantedinternal walls 106 before striking the back wall 102 (if theback wall 102 is reached at all). Thus, thearmor system 100 prevents damage to the armored structure (e.g., protected wall or other surface of a vehicle, housing structure, or other enclosure) or at least prevents full penetration of thearmor system 100 itself (i.e., prevents the projectile from penetrating the back wall 102) because the projectile is at least partially deflected at an angle by thefront wall 104 or by one of theinternal walls 106. For example, if the projectile trajectory is normal to thefront wall 104 and the projectile penetrates through thefront wall 104, it will hit at least one of theinternal walls 106 at an angle to the normal. If the projectile hits thefront wall 104 at an angle, it will be at least partially deflected by thefront wall 104 and will also hit at least one of theinternal walls 106 and/or theback wall 102 at an angle. The projectile energy is therefore dissipated by deflecting the projectile at one or more angles. -
FIG. 2 shows an embodiment of thearmor system 100 further including a second plurality ofinternal walls 110 spaced apart from one another and angled with respect to the firstinternal walls 106. In some implementations, each secondinternal wall 110 is angled with respect to an adjacent firstinternal wall 106 at an angle of about ninety degrees, though other angles may be appropriate. Each of the secondinternal walls 110 may extend between adjacent firstinternal walls 106. For example, a secondinternal wall 110 can be fixed on one end to a first one of the firstinternal walls 106 and on the other end to a neighboring one of the firstinternal walls 106. In this manner, a projectile passing directly through thefront wall 104 will strike at least one of the firstinternal walls 106, at least one of the secondinternal walls 110, or both, before striking theback wall 102. - An example
projectile path 112 is shown inFIG. 2 to illustrate the manner by which the projectile can be deflected at multiple angles by a combination of thefront wall 104 and at least one of the firstinternal walls 106 and/or at least one of the secondinternal walls 110 before reaching the back wall 102 (if theback wall 102 is reached at all). When a projectile (e.g., a bullet) strikes thefront wall 104 of the armor system 100 (e.g., at a normal or near normal angle to the strike face of the front wall 104), if thefront wall 104 does not stop it, the projectile will slow and may be deformed (e.g., a point of a bullet may become rounded or otherwise deformed). The projectile may then strike a first angled face of one of the firstinternal walls 106, where it will be less likely to dig into the face, but instead may be deflected; whereupon the projectile will strike a second angled face of one of the secondinternal walls 110; and then, if still moving, the projectile may strike the back wall 102 (e.g., at an angle whereupon most of its energy will be spent) and may then stop, unable to penetrate theback wall 102; or the projectile may simply be deflected off the secondinternal wall 110 without ever reaching theback wall 102. In implementations where thearmor system 100 only includes the first plurality ofinternal walls 106, or where the first andsecond walls internal wall 106 will be greater than the energy required to penetrate the front wall 104 (due to the angled face of the first internal wall 106). Thus, even if the projectile penetrates the angled face of the firstinternal wall 106, the projectile energy will be substantially reduced or dissipated, thereby preventing the projectile from penetrating theback wall 102. - At least one of the first
internal walls 106 and the secondinternal walls 110 can be formed from an alloy, a composite material, or a ballistic material. For example, the firstinternal walls 106 or the secondinternal walls 110, or both, can be formed from steel or hardened steel, a reinforced plastic, a ceramic composition, DYNEEMA, or KEVLAR. Thefront wall 104 or theback wall 102, or both, can also be formed from one of the foregoing materials. In some embodiments, at least one of thefront wall 104, theback wall 102, the first plurality ofinternal walls 106, the second plurality ofinternal walls 110, or a combination thereof, is surfaced with a hardened strike face (e.g., a hardened steel coating or the like). - In some embodiments, the
spaces 108 between adjacent internal walls (e.g., between adjacent ones of the firstinternal walls 106 or between a firstinternal wall 106 and an adjacent second internal wall 110) are left empty. In other embodiments, some or all of thesespaces 108 can be filled with a core material such as a foam, woven material, net-like material, or any other material (with a different composition or structure than the wall materials) that has at least one ballistic property configured to absorb or deflect projectile energy. -
FIGS. 3 and 4 show embodiments where theballistic armor system 100 comprises a plurality ofmodular armor units 114 that can be joined together to form an armor wall having any selected length or height. For example, eacharmor unit 114 can comprise a single structure including a portion of thefront wall 104, a portion of theback wall 102, and at least one of the first internal slanted walls 106 (extending from the front wall portion to the back wall portion). In some embodiments, eacharmor unit 114 can include a portion of thefront wall 104, a portion of theback wall 102, at least two of the first internal walls 106 (extending from the front wall portion to the back wall portion), and at least one second internal wall 110 (extending from one of the first internal walls to another one of the first internal walls) as shown inFIGS. 3 and 4 . In embodiments, anupper edge 116 of themodular armor unit 114 is mateable with alower edge 118 of a secondmodular armor unit 114, such that multiplemodular armor units 114 are configured to be mated together to form a ballistic wall of a selected length and/or height. - Each
modular armor unit 114 can be formed by extruding or pultruding its base material laterally in a direction parallel to a face of one or more of the walls to create a parallelogram section of extended length with one or more internal walls. For example, eachmodular armor unit 114 can be manufactured to include at least one of the firstinternal walls 106 between front and back wall portions, or to include at least one firstinternal wall 106 between front and back wall portions, and at least one secondinternal wall 110 attached to the firstinternal wall 106. The front and back wall portions of the parallelogram section are extended out to form theupper edge 116 of themodular armor unit 114. In embodiments, each of theupper edges 116 can be a distance beyond an intersection of the uppermost internal wall (e.g., an uppermost one of the firstinternal walls 106 for the armor unit 114) with a respective portion of thefront wall 104 or theback wall 102. Each of thelower edges 118 of themodular armor unit 114 can be indented inward a distance approximately equal to a wall thickness of a respective portion of thefront wall 104 or theback wall 102, or at least a distance equal to a thickness of a respective one of the upper edges 116. Each of thelower edges 116 can also extend for a distance up from an intersection of the lowermost internal wall (e.g., a lowermost one of the first internal walls 106) with a respective portion of thefront wall 104 or theback wall 102, such that the extension of eachupper edge 116 is approximately equal to the indentation of a respectivelower edge 118. Theupper edge 116 andlower edge 118 configurations can be reversed (e.g., where theupper edges 116 are indented and thelower edges 118 are extended) or mixed (e.g., where a firstupper edge 116 is extended and a respectivelower edge 118 is indented, and a secondupper edge 116 is indented and a respectivelower edge 118 is extended), or otherwise configured to be mated with one another in a similar fashion to that described herein. - The
modular armor units 114 can be glued, welded, or pressed together to form an armor wall of thearmor system 100 having any desired length or height. In some embodiments, at least one of themodular armor units 114 includes a curved or angled portion of thefront wall 104 or portion of theback wall 104, or both. In this manner, themodular armor unit 114 can be assembled with other modular armor units that are not curved or angled (e.g., the curved/angled units can be alternated) to produce corners and offsets or segmented round ballistic walls. This creates additional angled surfaces to increase deflection of a projectile striking a portion of thefront wall 104, and sometimes also a portion of theback wall 102. -
FIG. 5 shows a corner (e.g., top or bottom corner)unit 200 for theballistic armor system 100 that can be modular or it can be manufactured as a single structure that has a size and shape allowing it to fit within or receive a modular armor unit at least one end. For example, the corner unit can include indented orextended edges 210 that are configured to mate withupper edges 116 orlower edges 118 of amodular armor unit 114, as shown inFIG. 6 where a plurality ofmodular armor units 114 are connected together and an end unit of themodular armor units 114 is connected to thecorner unit 200. In embodiments, thecorner unit 200 includes anouter wall 208 and aninner wall 206 with at least a first plurality ofinternal walls 202 fixed in between theouter wall 208 and theinner wall 206 in a similar fashion to the first plurality ofinternal walls 106 fixed between thefront wall 104 and theback wall 102. The corner unit can also include a second plurality ofinternal walls 204 fixed with respect to the first plurality ofinternal walls 202 in a similar fashion to the second plurality ofinternal walls 110 fixed with respect to the first plurality ofinternal walls 106. - It will be understood by those within the art that, in general, terms used herein, and are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations.
- In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
- In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
- Although particular embodiments of this invention have been illustrated, it is apparent that various modifications and embodiments of the invention may be made by those skilled in the art without departing from the scope and spirit of the foregoing disclosure. Accordingly, the scope of the invention should be limited only by the claims appended hereto.
