Iron Armour
Iron armour was a type of naval armour used on warships and, to a limited degree, fortifications. The use of iron gave rise to the term ironclad as a reference to a ship 'clad' in iron. The earliest material available in sufficient quantities for armouring ships was iron, wrought or cast. While cast iron has never been used for naval armour, it did find a use in land fortifications, presumable due to the lower cost of the material. One well known example of cast-iron armour for land use is the Gruson turret, first tested by the Prussian government in 1868. Armoured ships may have been built as early as 1203, in the far east. In the West, they first become common when France launched the first ocean-going ironclad ''La Gloire'' in 1859. The British Navy responded with HMS ''Warrior'' in 1860, triggering a naval arms race with bigger, more heavily armed and armoured ironclads. Early experiments showed that wrought iron was superior to cast iron, and wrought iron was subsequently ado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Warrior (1860) Bulkhead Armour
At least five ships and one shore establishment of the Royal Navy have been named HMS ''Warrior'': * was a 74-gun third-rate ship of the line launched in 1781. She became a receiving ship after 1818, a convict ship after 1840, and was broken up in 1857. * was the Royal Navy's first ironclad ocean-going armoured battleship and world's first iron-hulled ironclad, and was launched in 1860. She became a depot ship in 1902, was renamed HMS ''Vernon III'' in 1904, and hulked as HMS ''Warrior'' in 1923. She was handed over for preservation as ''Warrior'' in 1979, and is preserved at Portsmouth as a museum ship. * was a armoured cruiser launched in 1905. She was disabled at the Battle of Jutland in 1916 and foundered a day later. * was a yacht requisitioned by the Royal Navy in 1917 and 1918 * was a light fleet aircraft carrier An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deplo ...

US Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Laminated Armour
Lamination is the technique/process of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, sound insulation, appearance, or other properties from the use of the differing materials, such as plastic. A laminate is a permanently assembled object created using heat, pressure, welding, or adhesives. Various coating machines, machine presses and calendering equipment are used. Materials There are different lamination processes, depending primarily on the type or types of materials to be laminated. The materials used in laminates can be identical or different, depending on the process and the object to be laminated. Textile Laminated fabric are widely used in different fields of human activity, including medical and military. Woven fabrics (organic and inorganic based) are usually laminated by different chemical polymers to give them useful properties like chemical resistance, dust, grease, windproofness, photolumines ...

Spall
Spall are fragments of a material that are broken off a larger solid body. It can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure (as in a ball bearing). Spalling and spallation both describe the process of surface failure in which spall is shed. The terms ''spall'', ''spalling'', and ''spallation'' have been adopted by particle physicists; in neutron scattering instruments, neutrons are generated by bombarding a uranium (or other) target with a stream of atoms. The neutrons that are ejected from the target are known as "spall". Mechanical spalling Mechanical spalling occurs at high stress contact points, for example, in a ball bearing. Spalling occurs in preference to brinelling where the maximal shear stress occurs not at the surface, but just below, shearing the spall off. One of the simplest forms of mechanical spalling is plate impact, in which two waves of compression ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Artillery
The Royal Regiment of Artillery, commonly referred to as the Royal Artillery (RA) and colloquially known as "The Gunners", is one of two regiments that make up the artillery arm of the British Army. The Royal Regiment of Artillery comprises thirteen Regular Army regiments, the King's Troop Royal Horse Artillery and five Army Reserve regiments. History Formation to 1799 Artillery was used by the English army as early as the Battle of Crécy in 1346, while Henry VIII established it as a semi-permanent function in the 16th century. Until the early 18th century, the majority of British regiments were raised for specific campaigns and disbanded on completion. An exception were gunners based at the Tower of London, Portsmouth and other forts around Britain, who were controlled by the Ordnance Office and stored and maintained equipment and provided personnel for field artillery 'traynes' that were organised as needed. These personnel, responsible in peacetime for maintaining the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Engineers
The Corps of Royal Engineers, usually called the Royal Engineers (RE), and commonly known as the ''Sappers'', is a corps of the British Army. It provides military engineering and other technical support to the British Armed Forces and is headed by the Chief Royal Engineer. The Regimental Headquarters and the Royal School of Military Engineering are in Chatham in Kent, England. The corps is divided into several regiments, barracked at various places in the United Kingdom and around the world. History The Royal Engineers trace their origins back to the military engineers brought to England by William the Conqueror, specifically Bishop Gundulf of Rochester Cathedral, and claim over 900 years of unbroken service to the crown. Engineers have always served in the armies of the Crown; however, the origins of the modern corps, along with those of the Royal Artillery, lie in the Board of Ordnance established in the 15th century. In Woolwich in 1716, the Board formed the Royal Regime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Pole
William Pole FRS FRSE MICE (22 April 181430 December 1900) was an English engineer, astronomer, musician and an authority on Whist. Life He was born in Birmingham on 22 April 1814, the son of Thomas Pole. Pole was apprenticed as an engineer to Charles H. Capper in Birmingham around 1828. He then went to India in 1844 as professor of engineering at Elphinstone College, Bombay, where he had organized a course of instruction for Indian students; his health obliged him to return to England in 1848. For the next ten years he worked in London under James Simpson and James Meadows Rendel, and was appointed in 1859 to the chair of civil engineering at University College, London. With official work from the government, he served on committees which considered the application of armour to ships and fortifications (1861–1864), and the comparative advantages of Whitworth and Armstrong guns (1863–1865). Pole was secretary to the Royal Commission on Railways (1865–1867), the Duke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Percy (metallurgist)
John Percy FRS (23 March 1817 – 19 June 1889) was an English metallurgist. Life The third son of Henry Percy, a solicitor, he was born at Nottingham on 23 March 1817. He went to a private school at Southampton, and then returned to Nottingham, where he attended chemical lectures by a Mr. Grisenthwaite at the local school of medicine. He wished to become a chemist; but his father's wish was that he should graduate in medicine, and in April 1834 he was taken by his brother Edmund to Paris to begin his medical studies. While in Paris he attended the lectures of Joseph Louis Gay-Lussac and Louis Jacques Thénard on chemistry, and of Antoine Laurent de Jussieu on botany. In 1836 Percy went for a tour in Switzerland and the south of France, and made a collection of mineralogical and botanical specimens. He went on to Edinburgh, where he became a pupil of Sir Charles Bell and a friend of Edward Forbes. In 1838 he graduated M.D. in the university, and received a gold medal for a ...

Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mi ...
