Circle A circle is a simple closed shape in Euclidean geometry. It is the set of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves so that its distance from a given point is constant. The distance between any of the points and the centre is called the radius.

Flak jacket A flak jacket or flak vest is a form of body armor designed to provide protection from case fragments ("frag") from high explosive weaponry, such as anti-aircraft artillery ("flak" a German contraction for "Fliegerabwehrkanone" ("aircraft-defense gun")), grenades, some round shot used in shotguns and land mines and other lower-velocity projectiles. It is not designed to protect against bullets fired from small arms such as rifles or handguns. However, certain flak jackets are able to sustain certain gunshots, depending on the armor, the projectile, and the range from which the shot was fired.

Aeroshell An aeroshell is a rigid heat-shielded shell that helps decelerate and protects a spacecraft vehicle from pressure, heat, and possible debris created by drag during atmospheric entry (see blunt body theory). Its main components consist of a heat shield (the forebody) and a back shell. The heat shield absorbs heat caused by air compression in front of the spacecraft during its atmospheric entry. The back shell carries the load being delivered, along with important components such as a parachute, rocket engines, and monitoring electronics like an inertial measurement unit that monitors the orientation of the shell during parachute-slowed descent.

Puzzle globe A puzzle globe (also called "jigsaw globe", "globe puzzle", "puzzle ball", "puzzle sphere" or "spherical puzzle") is a spherical assembly of puzzle pieces that, when put together, form a complete sphere or globe. Puzzle globes will generally have a one-piece spherical substrate that supports the puzzle pieces as they are laid in place. In some puzzle globes the substrate is steel and the puzzle pieces are magnetic, the magnetic attraction keeping pieces on the lower portion of the sphere from falling off.

Dahlbusch Bomb A Dahlbusch Bomb is an emergency evacuation device for use in mining. In its original form it is a torpedo-shaped cylinder with a length of 2.5 metres (8.2 ft), developed to transport trapped miners through boreholes after mining accidents. It does not contain explosive: it was called a "bomb" because of its shape.

Circumscribed sphere In geometry, a circumscribed sphere of a polyhedron is a sphere that contains the polyhedron and touches each of the polyhedron's vertices. The word circumsphere is sometimes used to mean the same thing. As in the case of two-dimensional circumscribed circles, the radius of a sphere circumscribed around a polyhedron "P" is called the circumradius of "P", and the center point of this sphere is called the circumcenter of "P".

MATS/1.4 mine The MATS/1.4 is a scatterable Italian circular, plastic-cased minimum metal blast-resistant anti-tank blast mine. It uses a pneumatic fuze which is resistant to shock and blast. The mine's plastic case is waterproof, and the mine can be scattered from a helicopter travelling at up to 200 km/h. The mine is normally tan-colored. The mine's main charge is relatively small, so when hand-emplaced the mine can be stacked, to increase its effect.

Sphericity Sphericity is the measure of how closely the shape of an object approaches that of a mathematically perfect sphere. For example, the sphericity of the balls inside a ball bearing determines the quality of the bearing, such as the load it can bear or the speed at which it can turn without failing. Sphericity is a specific example of a compactness measure of a shape. Defined by Wadell in 1935, the sphericity, formula_1, of a particle is: the ratio of the surface area of a sphere (with the same volume as the given particle) to the surface area of the particle:

Simplicial sphere In geometry and combinatorics, a simplicial (or combinatorial) "d"-sphere is a simplicial complex homeomorphic to the "d"-dimensional sphere. Some simplicial spheres arise as the boundaries of convex polytopes, however, in higher dimensions most simplicial spheres cannot be obtained in this way.

Dynamic Armor Dynamic Armor or Electric Armour is a type of armour which has been proposed for the protection of ships from shaped charge weapons. The idea is that the system uses a strong electric field to disrupt the jet of ionized gas produced by the warhead. The system has been proposed as an upgrade to the "Gerald R. Ford"-class supercarriers .

Iron Fist (countermeasure) Iron Fist (Hebrew: חץ דורבן‎ ‎ , "Hetz Dorban", "lit." Porcupine Arrow) is a hard-kill active protection system (APS) designed by Israel Military Industries (IMI), with a modular design allowing adaptation to a range of platforms ranging from light utility vehicles to heavy armoured fighting vehicles. The concept was revealed by IMI in 2006 and was expected to enter Israel Defense Forces tests by mid-2007. The system has been successfully tested against a wide variety of threats including rocket-propelled grenades, anti-tank guided missiles and tank-fired HEAT ammunition and kinetic energy penetrators.

Cyclogon In mathematics, in geometry, a cyclogon is the curve traced by a vertex of a polygon that rolls without slipping along a straight line. There are no restrictions on the nature of the polygon. It can be a regular polygon like an equilateral triangle or a square. The polygon need not even be convex: it could even be a star-shaped polygon. More generally, the curves traced by points other than vertices have also been considered. In such cases it would be assumed that the tracing point is rigidly attached to the polygon. If the tracing point is located outside the polygon, then the curve is called a "prolate cyclogon", and if it lies inside the polygon it is called a "curtate cyclogon".

Nose cone design Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance. For many applications, such a task requires the definition of a solid of revolution shape that experiences minimal resistance to rapid motion through such a fluid medium, which consists of elastic particles.

Point-blank range Point-blank range is any distance over which the trajectory of a given projectile fired from a given weapon remains sufficiently flat that one can strike a target by firing at it directly. Point-blank range will vary by a weapon's

Subterrene A Subterrene (, Russian: Подземная лодка ) is a vehicle that travels underground (through solid rock/soil) much as a submarine travels underwater, either by mechanical drilling, or by melting its way forward. Subterrenes existed first in fiction as mechanical drillers, with real-world thermal designs and examples following in the second half of the 20th century.
