Rifled Breechloader
A rifled breech loader (RBL) is an artillery piece which, unlike the smoothbore cannon and rifled muzzle loader which preceded it, has rifling in the barrel and is loaded from the breech at the rear of the gun. The spin imparted by the gun's rifling gives projectiles directional stability and increased range. Loading from the rear of the gun leaves the crew less exposed to enemy fire, allows smaller gun emplacements or turrets, and allows a faster rate of fire. These rapidly improving breech systems and the powerful new guns they facilitated led to an arms race in fortification and ironclad warship design that led to the battleship class of HMS ''Dreadnought'' and continued until the start of World War I. Overview The major problem to be solved with breechloading artillery was obturation: the sealing of the breech after firing to ensure that none of the gases generated by the burning of the propellant (initially gunpowder) escaped rearwards through the breech. This was both a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artillery
Artillery consists of ranged weapons that launch Ammunition, munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons were developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to Shell (projectile), shell-firing Field gun, guns, howitzers, and Mortar (weapon), mortars (collectively called ''barrel artillery'', ''cannon artil ...

Interrupted Thread
Breech from Russian 122 mm M1910 howitzer, modified and combined with 105 mm H37 howitzer barrel An interrupted screw or interrupted thread is a mechanical device typically used in the breech of artillery guns. It is believed to have been invented in 1845. The system has also been used to close other devices, including the joint between helmet (bonnet) and breastplate (corselet) of standard diving suit helmets, and the locks of diving chambers. Design An interrupted screw has a section of thread along its axis removed. The screw is mated with a partially threaded hole in the receptacle: threadless channels in the breechblock screw line up with the threaded parts of the receptacle, and vice versa. The screw can thus be smoothly inserted all the way into the receptacle, after which as little as one-eighth of a turn can engage the two sets of threads securely, sealing the joint. The amount of rotation required to achieve full closure depends on the number of unthreaded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Arsenal
The Royal Arsenal, Woolwich is an establishment on the south bank of the River Thames in Woolwich in south-east London, England, that was used for the manufacture of armaments and ammunition, proof test, proofing, and explosives research for the British armed forces. It was originally known as the Woolwich Warren, having begun on land previously used as a Warren (domestic), domestic warren in the grounds of a mid-16th century Tudor house, Tower Place. Much of the initial history of the site is linked with that of the Office of Ordnance, which purchased the Warren in the late 17th century in order to expand an earlier base at Gun Wharf in Woolwich Dockyard. Over the next two centuries, as operations grew and innovations were pursued, the site expanded massively. At the time of the World War I, First World War the Arsenal covered and employed close to 80,000 people. Thereafter its operations were scaled down. It finally closed as a factory in 1967 and the Ministry of Defence m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elswick Ordnance Company
The Elswick Ordnance Company (sometimes referred to as Elswick Ordnance Works, but usually as "EOC") was a British armaments manufacturing company of the late 19th and early 20th century History Originally created in 1859 to separate William Armstrong's armaments business from his other business interests, to avoid a conflict of interest as Armstrong was then Engineer of Rifled Ordnance for the War Office and the company's main customer was the British Government. Armstrong held no financial interest in the company until 1864 when he left Government service, and Elswick Ordnance was re-united with the main Armstrong businesses to form Sir W.G. Armstrong & Company. EOC was then the armaments branch of W.G. Armstrong & Company and later of Armstrong Whitworth. EOC's main customer in its early years was the British Government, but the Government abandoned "Armstrong guns" in the mid-1860s due to dissatisfaction with Armstrong's breech mechanism, and instead built its own rifled ...

William Armstrong, 1st Baron Armstrong
William Armstrong, 1st Baron Armstrong, (26 November 1810 – 27 December 1900) was an English engineer and industrialist who founded the Armstrong Whitworth manufacturing concern on Tyneside. He was also an eminent scientist, inventor and philanthropist. In collaboration with the architect Richard Norman Shaw, he built Cragside in Northumberland, the first house in the world to be lit by hydroelectricity. He is regarded as the inventor of modern artillery. Armstrong was knighted in 1859 after giving his gun patents to the government. In 1887, in Queen Victoria's golden jubilee year, he was raised to the peerage as Baron Armstrong of Cragside. Early life Armstrong was born in Newcastle upon Tyne at 9 Pleasant Row, Shieldfield, Although the house in which he was born no longer exists, an inscribed granite tablet marks the site where it stood. At that time the area, next to thPandon Dene was rural. His father, also called William, was a corn merchant on the Newcastle quaysi ...

Crimean War
The Crimean War was fought between the Russian Empire and an alliance of the Ottoman Empire, the Second French Empire, the United Kingdom of Great Britain and Ireland, and the Kingdom of Sardinia (1720–1861), Kingdom of Sardinia-Piedmont from October 1853 to February 1856. Geopolitical causes of the war included the "Eastern question" (Decline and modernization of the Ottoman Empire, the decline of the Ottoman Empire, the "sick man of Europe"), expansion of Imperial Russia in the preceding Russo-Turkish wars, and the British and French preference to preserve the Ottoman Empire to maintain the European balance of power, balance of power in the Concert of Europe. The flashpoint was a dispute between France and Russia over the rights of Catholic Church, Catholic and Eastern Orthodox Church, Orthodox minorities in Palestine (region), Palestine. After the Sublime Porte refused Nicholas I of Russia, Tsar Nicholas I's demand that the Empire's Orthodox subjects were to be placed unde ...

Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/ shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Several factors, including the type of firearm, the cartridge, and the barrel length, determine the bullet's muzzle velocity. Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''super ...

Sardinian Army
The Royal Sardinian Army (also the Sardinian Army, the Royal Sardo-Piedmontese Army, the Savoyard Army, or the Piedmontese Army) was the army of the Duchy of Savoy and then of the Kingdom of Sardinia, which was active from 1416 until it became the Royal Italian Army on 4 May 1861. Generally, the term "Savoyard Army" is used for the period when the rulers of Savoy held only the title of Duke, while "Sardinian Army" is preferred for the period after they obtained the title of King of Sardinia in 1720. History Origins The Savoyard Army was officially established in the 15th century when the Duchy of Savoy was created. During this period, the army of the Savoyard lands was concentrated at bases in Piedmont and the Aosta Valley, where it was maintained by the local feudal lords who in exchange for the command of some regiments, maintained them for state service and stationed them on the land in the meantime. It was Duke Emmanuel Philibert who was largely responsible for the rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giovanni Cavalli
Lieutenant general Giovanni Cavalli (Novara, 23 July 1808 – Turin, 23 December 1879) was an Italian soldier, artillerist and inventor. He is credited with the creation of the first successful rifled breech loader gun. Biography He entered the Royal Academy of Turin in 1818, and graduated from it in 1828 as first of his class, with the rank of lieutenant. He worked on ways to reform and improve the work of artillerist and pontoneers, detailing proposals to change size and duties of gun crews, the procedures to drill them, among others. Then-captain Cavalli's first design for a breech-loading gun dated from 1832, but initially it was met with indifference; only in 1843 his proposal sparked some interest, and he was sent to Sweden to oversee the construction of an experimental rifled gun to his specifications. He met there and collaborated with Baron Martin von Wahrendorff, and in 1846 the first trials with the gun met with resounding success. He fought in the First War of Ital ...

Martin Von Wahrendorff
Martin von Wahrendorff (1789 – 1861) was a Swedish diplomat and inventor. His father Anders von Wahrendorff was the owner of the gun foundry at Åker. Wahrendorff was Grand Master of Ceremonies at the Royal Court of Sweden from 1828 to 1831 In 1837 Wahrendorff applied for patent on a new breech mechanism, later known as the Wahrendorff breech. The first breech loaded Wahrendorff gun was manufactured at Åker in 1840. In the 1840s the Sardinian major Giovanni Cavalli was sent to the Åker foundry to inspect guns that the Sardinian government had ordered. The two then started experimenting with pointed elongated lead-coated projectile A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found ...s fired from rifled, breech loading, guns of Wahrendorff's design. In 1854 the Swedish Ar ...
