Armor element and an armor module comprising the same
An armor element configured to be employed within the armor module, the armor element being formed with a base portion and a claw portion. The armor element has a longitudinal axis oriented substantially perpendicular to the base portion, the claw portion comprising two or more claw members extending from the base portion generally along a longitudinal direction defined by the longitudinal axis. Each claw member has a rear end associated with the base portion and a front end spaced from the base portion. The claw members are tapered with respect to the longitudinal axis so that the distance between the corresponding front ends of the two or more claw members is greater than the distance between the rear ends of the two or more claw members.
1. An armor element configured to be employed within an armor module and exhibiting a longitudinal axis, the armor element comprising:
a base portion including a rear surface and a front surface axially spaced from the rear surface along the longitudinal axis;
a claw portion comprising two or more claw members, the two or more claw members extending from the base portion generally along a longitudinal direction defined by the longitudinal axis, each of the two or more claw members having a rear end attached to the base portion and a free front end spaced from the rear end thereof and located axially beyond the front surface of the base portion, each of the two or more claw members being supported only at the rear end thereof; and
wherein the two or more claw members project radially outwardly with respect to the longitudinal axis so that an outer diametric distance between the corresponding free front ends of the two or more claw members is greater than an outer diametric distance between the corresponding rear ends of the two or more claw members.
2. The armor element according to claim 1 , wherein an angle between each of the two or more claw members and the longitudinal axis is chosen to be no greater than 50°.
3. The armor element according to claim 1 , wherein the two or more claw members are substantially symmetrically located and substantially equally spaced about the longitudinal axis.
4. The armor element according to claim 1 , wherein each of the two or more claw members is formed with a plurality of edges, each of the two or more claw members is defined by surfaces, each of the plurality of edges being formed at an intersection between two or more of the surfaces.
5. The armor element according to claim 1 , wherein the each of the two or more claw members is formed with any one of the following:
an external surface associated with an inscribing cone and extending about the circumference of the claw portion;
one or more side surfaces extending generally radially from the external surface towards the central axis; or
a front surface associated with the free front end of the claw member, the front surface extending between the one or more side surfaces and the external surface.
6. The armor element according to claim 5 , wherein, when the two or more claw members are formed with the front surface, an auxiliary tapering angle is defined between corresponding front surfaces of the two or more claw members, the auxiliary tapering angle being greater than a tapering angle between the two or more claw members.
7. The armor element according to claim 6 , wherein the auxiliary tapering angle is no greater than 120°.
8. The armor element according to claim 1 , wherein a diameter D CLAW of the inscribing circle defined by the free front ends of the claw members is not significantly greater than a diameter D BASE of the inscribing circle of the base portion.
9. The armor element according to claim 8 , wherein the ratio D CLAW /D BASE is no greater than 2.
