Hollow Charge
A shaped charge is an explosive charge shaped to form an explosively formed penetrator (EFP) to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD), though greater depths of 10 CD and above have been achieved. Contrary to a misconception (possibly resulting from the acronym for ''high-explosive anti-tank'', HEAT) the shaped charge EFP jet does not depend in any way on heating or melting for its effectiveness; that is, the EFP jet from a shaped charge does not melt its way through armor, as its effect is purely kinetic in nature – however the process does create significant heat and often has a significa ...

Düsseldorf
Düsseldorf ( , , ; often in English sources; Low Franconian and Ripuarian: ''Düsseldörp'' ; archaic nl, Dusseldorp ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state and the seventh-largest city in Germany, with a population of 617,280. Düsseldorf is located at the confluence of two rivers: the Rhine and the Düssel, a small tributary. The ''-dorf'' suffix means "village" in German (English cognate: ''thorp''); its use is unusual for a settlement as large as Düsseldorf. Most of the city lies on the right bank of the Rhine. Düsseldorf lies in the centre of both the Rhine-Ruhr and the Rhineland Metropolitan Region. It neighbours the Cologne Bonn Region to the south and the Ruhr to the north. It is the largest city in the German Low Franconian dialect area (closely related to Dutch). Mercer's 2012 Quality of Living survey ranked Düsseldorf the sixth most livable city in the world.

Panzerschreck
''Panzerschreck'' (lit. "tank fright", "tank's fright" or "tank's bane") was the popular name for the ''Raketenpanzerbüchse'' 54 ("Rocket Anti-armor Rifle Model 54", abbreviated to RPzB 54), an 88 mm reusable anti-tank rocket launcher developed by Nazi Germany in World War II. Another earlier, official name was ''Ofenrohr'' ("stove pipe"). The ''Panzerschreck'' was designed as a lightweight infantry anti-tank weapon and was an enlarged copy of the American bazooka. The weapon was shoulder-launched and fired a fin-stabilized rocket with a shaped-charge warhead. It was made in smaller numbers than the ''Panzerfaust'', which was a light, disposable anti-tank weapon that used a system not unlike those of recoilless rifles. History The ''Panzerschreck'' development was initially based on the American "bazooka", captured during the Tunisian campaign, November 1942. The ''Panzerschreck'' was larger and heavier than its American counterpart – the ''Panzerschreck'' had an 88 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Mohaupt
Wolfdieter Hans-Jochem Mohaupt, known as Heinrich Mohaupt, in the U.S. Henry (Hans) Mohaupt (August 16, 1915 – May 20, 2001) was a Swiss American inventor. He first demonstrated and exhibited shaped charge warheads internationally before the Second World War. Prior to 1939, Mohaupt demonstrated his invention to British and French ordnance authorities. Concurrent development by the German group of Cranz, Schardin, and Thomanek led to the first documented use of shaped charges in warfare, in a successful assault on the fort of Eben Emael, on 10 May 1940. Claims for priority of invention are difficult to resolve due to subsequent historic interpretations, secrecy, espionage, and international commercial interest. Biography Early life and education Heinrich Mohaupt was born on 16 August 1915 in Egg ZH, Switzerland. His parents were Flora Mathilde and Berthold Mohaupt. He had an older sister, Deziré Liselotte. His father Berthold Mohaupt was born in Breslau in Germany but was n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubert Schardin
Hubert Hermann Reinhold Schardin (17 June 1902 Plassow – 27 September 1965 in Freiburg im Breisgau) was a German ballistics expert, engineer and academic who studied in the field of high-speed photography and cinematography. He also was the director of the German-French Research Institute (ISL) in Saint-Louis (France) and founder and director of the Fraunhofer Society Institute for High-Speed Dynamics - Ernst-Mach-Institut (EMI) - in Freiburg im Breisgau. Scientific importance The main importance of Schardin's scientific activities is in high-speed physics. He extended the research of Ernst Mach and Fritz Ahlborn, resulting in more than 1,000 publications. He influenced the development of electro- and high-speed exposures, electro-optical photography and high-speed cinematography with illumination by electric spark and flash x-rays. He developed high-speed measurement techniques, at first for the specific problems of ballistics, to a general scientific level of instrumentat ...
