Ablative armor is armor which prevents damage through the process of ablation, the removal of material from the surface of an object by vaporization, chipping, or other erosive processes. In contemporary spacecraft, ablative plating is most frequently seen as an ablative heat shield for a vehicle that must enter atmosphere from orbit, such as ...
Late medieval gothic plate armour with list of elements. The slot in the helmet is called an occularium. This list identifies various pieces of body armour worn from the medieval to early modern period in the Western world, mostly plate but some mail armour, arranged by the part of body that is protected and roughly by date.
The first prototype of the shield was believed to be created in the Late Neolithic Age. However the oldest surviving shields date to sometime in the Bronze Age. [3] The oldest form of shield was a protection device designed to block attacks by hand weapons, such as swords, axes and maces, or ranged weapons like sling-stones and arrows.
A manica (Latin: manica, "sleeve"; [1] Greek: χεῖρες, kheires, "sleeves") was a type of iron or copper-alloy laminated arm guard with curved, overlapping metal segments or plates fastened to leather straps worn by ancient and late antique heavy cavalry, infantry, and gladiators.
Whipple shield used on NASA's Stardust probe. The Whipple shield or Whipple bumper, invented by Fred Whipple, [1] is a type of spaced armor shielding to protect crewed and uncrewed spacecraft from hypervelocity impact / collisions with micrometeoroids and orbital debris whose velocities generally range between 3 and 18 kilometres per second (1.9 and 11.2 mi/s).
Buckler front and back Sword and buckler combat, plate from the Tacuinum Sanitatis illustrated in Lombardy, ca. 1390. Irish round shield. A buckler (French bouclier 'shield', from Old French bocle, boucle 'boss') is a small shield, up to 45 cm (up to 18 in) in diameter, [1] gripped in the fist with a central handle behind the boss.
Any opaque case, cowling, bodywork, fuselage, hull, wall, shield or armor will absorb at least the "first impact" of a laser weapon, so the beam must be sustained to achieve penetration. The Chinese People's Liberation Army has invested in the development of specialized coatings that can deflect beams fired by U.S. military lasers. Laser light ...
The shield rested on a man's shoulders, stretching down to the knees. It was theorized they were designed for a mass of hoplites to push forward into the opposing army, a move called othismos, and it was their most essential equipment, though this is now an outdated theory. [3] [4] The shield had a convex face, like that of a shallow bowl. [5]
