RDX Register
RDX (Research Department Explosive or Royal Demolition Explosive) or hexogen, among other names, is an organic compound with the formula (CH2N2O2)3. It is white, odorless, and tasteless, widely used as an explosive. Chemically, it is classified as a nitroamine alongside HMX, which is a more energetic explosive than TNT. It was used widely in World War II and remains common in military applications. RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive and a key ingredient in Semtex. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, with a relative effectiveness factor of 1.60. Name RDX is also less commonly known as cyclonite, hexogen (particularly in Russian, French and German-influenced languages), T4, and, chemically, as cyclotrimethylene trinitramine. In the 1930s, the Royal Arsenal, Woolwich, started investigat ... [...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] |
Grand Slam (bomb)
The Bomb, Medium Capacity, (Grand Slam) was a earthquake bomb used by RAF Bomber Command against German targets towards the end of the Second World War. The bomb was originally called Tallboy Large until the term Tallboy got into the press and the code name was replaced by "Grand Slam". The bomb was similar to a large version of the Tallboy bomb but a new design and closer to the size that its inventor, Barnes Wallis, had envisaged when he developed the idea of an earthquake bomb. It was the largest and most powerful conventional aerial bomb used by either side during the war. Medium Capacity (M.C.) bombs were designed to remedy the shortcomings of General Purpose (G.P.) bombs, with a greater blast and casings which were robust enough to confer a considerable capacity to penetrate, especially the Tallboy and Grand Slam. The Grand Slam case was made of a chrome-molybdenum alloy steel and had a charge-to-weight ratio of over 43 per cent. Standard Avro Lancaster bombers could ...

Tallboy (bomb)
Tallboy or Bomb, Medium Capacity, 12,000 lb was an earthquake bomb developed by the British aeronautical engineer Barnes Wallis and used by the Royal Air Force (RAF) during the Second World War."Medium capacity" refers to the ratio of bomb case to explosive filling; in the case of the Tallboy, this was less than 50 per cent explosive by weight, in contrast to "high capacity" bombs like the Blockbuster bombs, in which up to three-quarters of their weight was the explosive. At , it could be carried only by a modified model of the Avro Lancaster heavy bomber. It proved to be effective against large, fortified structures where conventional bombing had proved ineffective. History Wallis presented his ideas for a 10-ton bomb in his 1941 paper "A Note on a Method of Attacking the Axis Powers", which showed that a very large bomb exploding deep underground next to a target would transmit the shock into the foundations of the target, particularly since shock waves are transmitted ...

Operation Chastise
Operation Chastise, commonly known as the Dambusters Raid, was an attack on Nazi Germany, German dams carried out on the night of 16/17 May 1943 by No. 617 Squadron RAF, 617 Squadron RAF Bomber Command, later called the Dam Busters, using special bouncing bombs developed by Barnes Wallis. The Möhne Reservoir, Möhne and Edersee Dam, Edersee dams were breached, causing catastrophic flooding of the Ruhr (river), Ruhr valley and of villages in the Edertal, Eder valley; the Sorpe Dam sustained only minor damage. Two hydroelectric power stations were destroyed and several more damaged. Factories and mines were also damaged and destroyed. An estimated 1,600 civilians – about 600 Germans and 1,000 Forced labour under German rule during World War II, enslaved labourers, mainly Soviet – were killed by the flooding. Despite rapid repairs by the Germans, production did not return to normal until September. The RAF lost 56 aircrew, with 53 dead and three captured, amid losses of eight ...

Bouncing Bomb
A bouncing bomb is a bomb designed to bounce to a target across water in a calculated manner to avoid obstacles such as torpedo nets, and to allow both the bomb's speed on arrival at the target and the timing of its detonation to be predetermined, in a similar fashion to a regular naval depth charge. The inventor of the first such bomb was the British engineer Barnes Wallis, whose "Upkeep" bouncing bomb was used in the Royal Air Force, RAF's Operation Chastise of May 1943 to bounce into German dams and explode underwater, with an effect similar to the underground detonation of the later Grand Slam bomb, Grand Slam and Tallboy bomb, Tallboy earthquake bombs, both of which he also invented. British bouncing bombs After the outbreak of the Second World War in 1939, Wallis saw strategic bombing as the means to destroy the enemy's ability to wage war and he wrote a paper entitled "A Note on a Method of Attacking the Axis powers, Axis Powers". Referring to the enemy's power suppli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic Explosive
Plastic explosive is a soft and hand-moldable solid form of explosive material. Within the field of explosives engineering, plastic explosives are also known as putty explosives or blastics. Plastic explosives are especially suited for explosive demolition. Common plastic explosives include Semtex and C-4 (explosive), C-4. The first manufactured plastic explosive was gelignite in 1875, invented by Alfred Nobel. Usage Plastic explosives are especially suited for explosive demolition of obstacles and fortifications by combat engineers as they can be easily formed into ideal shapes for cutting structural members and have a high enough velocity of detonation and density for metal cutting work. An early use of plastic explosives was in the warhead of the Mortar (weapon)#Spigot mortar, Petard demolition mortar of the British Armoured Vehicle Royal Engineers (AVRE) which was used to destroy concrete fortifications encountered during Operation Overlord (D-Day). The original use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composition B
Composition B (Comp B), also known as Hexotol and Hexolite (among others), is a high explosive consisting of castable mixtures of RDX and TNT. It is used as the main explosive filling in artillery projectiles, rockets, land mines, hand grenades, and various other munitions. It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United Kingdom and United States.''Atom Bombs: The Top Secret Inside Story of Little Boy and Fat Man'', John Coster-Mullen, 2003Nuclear Weapons FAQ section 8.1.1: The Design of Gadget, Fat Man, and "Joe 1" (RDS-1) accessed August 10, 2009 The standard proportions of ingredients (by weight) are 59.5% RDX ( |
Torpex
Torpex ("Torpedo explosive") is a secondary explosive, 50% more powerful than TNT by mass. Torpex comprises 42% RDX, 40% TNT and 18% powdered aluminium. It was used in the Second World War from late 1942, at which time some used the names Torpex and RDX interchangeably. Torpex proved to be particularly useful in underwater munitions because the aluminium component made the explosive pulse last longer, which increased the destructive power. Besides torpedoes, naval mines, and depth charges, Torpex was also used in the M.C 500lb and 1000lb bombs, the 4000lb, 8000lb, and 12000lb "cookie" H.C bombs and in the Upkeep, Tallboy and Grand Slam bombs as well as the drones employed in Operation Aphrodite. Torpex has long been superseded by H6 and Polymer-bonded explosive (PBX) compositions. It is regarded as obsolete and Torpex is unlikely to be encountered except in old munitions or unexploded ordnance, although a notable exception to this is the Sting Ray lightweight torpedo, wh ...

Trinitrotoluene
Troponin T (shortened TnT or TropT) is a part of the troponin complex, which are proteins integral to the contraction of skeletal and heart muscles. They are expressed in skeletal and cardiac myocytes. Troponin T binds to tropomyosin and helps position it on actin, and together with the rest of the troponin complex, modulates contraction of striated muscle. The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. It was discovered by the German physician Hugo A. Katus at the University of Heidelberg, who also developed the troponin T assay. Subtypes * Slow skeletal troponin T1, TNNT1 (19q13.4, ) * Cardiac troponin T2, TNNT2 (1q32, ) * Fast skeletal troponin T3, TNNT3 (11p15.5, ) Reference values The 99th percentile cutoff for cardiac troponin T (cTnT) is 0.01 ng/mL. The reference range for the high sensitivity troponin T is a normal 52 ng/L. Backgr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombing Up 106 Squadron Lancaster WWII IWM CH 12541
A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term ''bomb'' is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shells, depth charges (used in water), or land mines. In unconventional warfare, other names can refer ...
