precast concrete

precast concrete is a construction product produced by casting concrete in a reusable mold or 'form' which is then cured in a controlled environment, transported to the construction site and lifted into place. in contrast, standard concrete is poured into site-specific forms and cured on site. precast stone is distinguished from precast concrete using a fine aggregate in the mixture, so the final product approaches the appearance of naturally occurring rock or stone. more recently expanded polys

wattle and daub

as discussed earlier, there were two popular choices for wattle and daub infill paneling: close-studded paneling and square paneling. close-studding. close-studding panels create a much more narrow space between the timbers: anywhere from 7 to 16 inches 18 to 40 cm . for this style of panel, weaving is too difficult, so the wattles run horizontally and are known as ledgers.

spoiler aeronautics

in aeronautics, a spoiler sometimes called a lift spoiler or lift dumper is a device intended to intentionally reduce the lift component of an airfoil in a controlled way. most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to spoil it. by so doing, the spoiler creates a controlled stall over the portion of the wing behind it, greatly .

vehicle armour

plastic metal was a type of vehicle armour originally developed for merchant ships by the british admiralty in 1940. the original composition was described as 50% clean granite of half-inch size, 43% of limestone mineral, and 7% of bitumen. it was typically applied in a layer two inches thick and backed by half an inch of steel.

north ward defence complex

north ward defence complex is a heritage-listed barracks at 46 oxley street, north ward, city of townsville, queensland, was built from 1885 to c. is also known as 11 brigade administration support battalion headquarters company and oxley street defence site.

leading-edge slat

the spring-loaded slat lies flush with the wing leading edge, held in place by the force of the air acting on them. as the aircraft slows down, the aerodynamic force is reduced and the springs extend the slats. sometimes referred to as handley-page slats. fixed the slat is permanently extended.

high-lift device

another common high-lift device is the slat, a small aerofoil shaped device attached just in front of the wing leading edge. the slat re-directs the airflow at the front of the wing, allowing it to flow more smoothly over the upper surface when at a high angle of attack.this allows the wing to be operated effectively at the higher angles required to produce more lift.

slat armor

slat armor, also known as bar armor, cage armor and standoff armor, is a type of vehicle armor designed to protect against anti-tank rocket-propelled grenade attacks. it takes the form of a rigid slatted metal grid fitted around key sections of the vehicle, which disrupts the shaped charge of the warhead by either crushing it, preventing optimal detonation from occurring, or by damaging the fuzing mechanism, preventing detonation outright. although slat armor is effective against incoming missil


modern airframe history began in the united states when a 1903 wood biplane made by orville and wilbur wright showed the potential of fixed-wing designs. in 1912 the deperdussin monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving 210 km/h 130 mph .


a louver american english or louvre british english is a window blind or shutter with horizontal slats that are angled to admit light and air, but to keep out rain and direct sunshine. the angle of the slats may be adjustable, usually in blinds and windows, or fixed.

wattle construction

wattle construction wattle is a lightweight construction material made by weaving thin branches either whole, or more usually split or slats between upright stakes to form a woven lattice. it has commonly been used to make fences and hurdles for enclosing ground or handling livestock.


a tailhook, arresting hook, or arrester hook is a device attached to the empennage rear of some military fixed-wing aircraft.the hook is used to achieve rapid deceleration during routine landings aboard aircraft carrier flight decks at sea, or during emergency landings or aborted takeoffs at properly equipped airports.
