LONDON E. & F. N. SPON, 125, STRAND. NEW YORK SPON & CHAMBERLAIN, 12, CORTLANDT STREET. 1892. MODERN GUNS AND SMOKELESS POWDER. PART I. INTRODUCTION. Gunpowder, the oldest of all explosives, has been the subject of many scientific investigations, sup- ported by innumerable experiments ; but Nature guards her secrets well ; and to this day it cannot be said that the cycle of chemical changes brought about by the combustion of gunpowder is thoroughly understood. Its original components vary, but are generally about 75 parts potassium nitrate, 15 parts carbon, and 10 parts sulphur, with other ingredients some- times added. These materials, when simply mixed together, burn with considerable vigour, but cannot rank as an explosive until they have been thoroughly incorporated, so that the different molecules are brought into such close proximity that each finds a neighbour ready and willing to combine on the smallest encouragement. Heat furnishes the necessary stimulus, by pro- 2 MODERN GUNS AND SMOKELESS POWDER. moting chemical activity ; and, when combined with concussion, the molecules are driven closer to- gether, and this intimate association accelerates their combination. The effect of mere concussion is shown to greater advantage when any of the more dangerous ex- plosives, such as iodide of nitrogen, are subjected to experiment.

Crawford K.R., Mitiukov N.W. 3 CAVALLI, WAHRENDORFF AND THE MAKING OF KRUPP The decade of the 1860s was a period of technical transition in naval warfare. Wood was giving way to iron for shipbuilding and armor protection. Smooth bore guns were giving way to rifles, both muzzle- and breech-loading. And the leading gun makers were graduating from cast iron to steel barrels. And the firm of W.G. Armstrong in Britain was rapidly rising to prominence in the field.

  • Background Reading on Explosives
    EXPLOSIVES 8/15/05 HISTORY Roger Bacon described the preparation of the first explosive, black gunpowder, in 1249. By 1300, it was known and used throughout Europe. Written descriptions and drawings of guns appeared in documents as early as 1325, but the active period of gunpowder warfare was not initiated until the English used guns in the battle of Cressy in 1346. In 1788, Berthollet, a student of Lavoisier, prepared a chlorate gunpowder but abandoned its use following a disastrous explosion. In 1800, Edward Howard described the preparation and properties of mercury fulminate (the preparation has not changed essentially to this day), but it was not until 1864 that Alfred Nobel adopted it for use in percussion caps. The discovery by Nobel that an explosive wave from the firing of a percussion cap could initiate the explosion of another explosive has been called the most important discovery and invention in the history of the explosive art. The history of modern explosives dates from the discovery of nitrocellulose (more correctly named cellulose nitrate) independently by Schonbein and Bottger in 1845. They soon perceived the military possibilities of their product and cooperated with each other to exploit a form of nitrocellulose called guncotton. Many disastrous explosions followed, both in the preparation and use of the explosive. These produced such unfavorable impressions that the manufacture of guncotton was discontinued in England, France, and Austria for many years. Glyceryl trinitrate, or nitroglycerine as it is commonly called, was first prepared by Sobrero, an Italian physician and chemist in 1846 or early 1847. He noted that the material was a powerful vasodilator - "a trace of nitroglycerine placed upon the tongue -- gives rise to a most violent pulsating headache" - and prescribed it medicinally in the treatment of angina pectoris (a common heart disease), a use that has continued to this day.

  • NZAR ID A79 Armstrong QF 12Pdr Guns in New Zealand by Dr John Osborne, AA, MG, DTT, Phd, FSG July 2005 Reviewed Feb 2016
    NZAR ID A79 Armstrong QF 12pdr Guns in New Zealand By Dr John Osborne, AA, MG, DTT, PhD, FSG July 2005 reviewed Feb 2016 In 1900 the New Zealand Government ordered 4 pillar mounted Quick Fire 12 pdr 12cwt MKI, 3”/40 (7.62cm) calibre guns which arrived in 1901 refer Fig 1. for details. Two were installed in Fort Gautley, Devonport, Auckland and two at Fort Ballance, Wellington, During 1914-18 these two guns were mounted on New Zealand mercantile vessels and after the war were installed at Fort Dorset, Seatoun, Wellington. These QF 12 pdrs remained in NZ Army Coastal Defence service until the disbanding of the New Zealand Coast Artillery in 1959. One of these guns is now on display at the QE II Army Memorial Museum, Waiouru, refer Fig 5. The Armstrong designed quick firing “QF” 12 pounder 12cwt Mark 1 gun was introduced in 1880 during the blackpowder propellant era, however the guns full potential was not realised until after 1887 when Alfred Nobel introduced smokeless powder propellant which became known as cordite, significantly more powerful and cleaner burning than blackpowder propellant. The QF 12pdr MK1 guns were manufactured to Armstrong’s fabricated built up barrel design technology and adopted by the British Royal Navy in 1881, and the British Army in 1894. The Barrels had polygroove Elswick Section progressive twist rifling which started at 1 in 120 increasing to 1 in 28 at the muzzle. The 120” (3.048m barrel bore length) when elevated to 40 degrees had a range using cordite ammunition of 11,750 yards (10,744m).
