Messerschmitt Me 163
The Messerschmitt Me 163 Komet is a rocket-powered interceptor aircraft primarily designed and produced by the German aircraft manufacturer Messerschmitt. It is the only operational rocket-powered fighter aircraft in history as well as the first piloted aircraft of any type to exceed in level flight. Development of what would become the Me 163 can be traced back to 1937 and the work of the German aeronautical engineer Alexander Lippisch and the '' Deutsche Forschungsanstalt für Segelflug'' (DFS). Initially an experimental programme that drew upon traditional glider designs while integrating various new innovations such as the rocket engine, the development ran into organisational issues until Lippisch and his team were transferred to Messerschmitt in January 1939. Plans for a propeller-powered intermediary aircraft were quickly dropped in favour of proceeding directly to rocket propulsion. On 1 September 1941, the prototype performed its maiden flight, quickly demon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into a number of classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibious aircraft, amphibians, and within these classes there are records for aircraft in a number of weight categories. There are still further subdivisions for Reciprocating engine, piston-engined, turbojet, turboprop, and Rocket engine, rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline Gray text indicates unofficial records, including unconfirmed or unpublicized war secrets.

Wasserkuppe
The Wasserkuppe (;) is the highest mountain in the Rhön Mountains, Rhön range and the tallest elevation in the Germany, German state of Hesse, standing at above sea level. It forms a prominent plateau within the Fulda district and is known as the "cradle of gliding". Great advances in sailplane development took place here during the Aviation between the World Wars, interwar period, driven by annual contests. To this day, an airfield near the summit continues to be used by gliding clubs and light aircraft pilots. Etymology The German language, German name is derived from ''Wasenkuppe, Asenberg'' or ''Weideberg'' and means ''Pasture mountain''. Geography The Wasserkuppe lies in the administrative district Fulda (district), Fulda north of Gersfeld. Other villages nearby are Poppenhausen, Hesse, Poppenhausen ( west - south west) and Wüstensachsen ( east, part of Ehrenberg, Hesse). It is part of the Rhön Biosphere Reserve. The Wasserkuppe sources the spring of the river Ful ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opel RAK
Opel-RAK were a series of rocket vehicles produced by German automobile manufacturer Fritz von Opel,https://www.airforcemag.com/article/0904rocket/ article by Walter J. Boyne in Air Force Magazine, September 1, 2004 of the Opel car company, in association with others, including Max Valier, Julius Hatry, and Friedrich Wilhelm Sander. Opel RAK is generally considered the world's first large-scale rocket program, significantly advancing rocket and aviation technology as well as instrumental in popularizing rockets as means of propulsion. In addition Opel RAK demonstrations were also highly successful as publicity stunts for the Opel car company. The Lippisch Ente (meaning “duck” in German), the world's first rocket-powered glider and piloted for its first flight on June 11, 1928, by Fritz Stamer at Wasserkuppe, was bought and operated by Opel in context of the Opel RAK program but is not formally designated an Opel RAK series number.

Yokosuka MXY-7 Ohka
The Yokosuka MXY-7 is a purpose-built, rocket-powered human-guided ''kamikaze'' attack-aircraft deployed by Japan against Allied ships in the Pacific Ocean theater toward the end of World War II. Although extremely fast, the ''Ohka'' had a very short range of , so it had to be carried into action as a parasite aircraft by a much larger bomber that was vulnerable to carrier-borne fighters. In action during the Battle of Okinawa in 1945, ''Ohka''s succeeded in sinking or damaging some escort-vessels and transport ships, but never sank any major warships. The Japanese developed improved versions in an attempt to overcome the aircraft's shortcomings, but they came too late for deployment. Allied personnel referred to the aircraft as "Baka Bombs" ( ''baka'' being a Japanese pejorative term meaning "fool" or "idiot"). Design and development The MXY-7 Navy Suicide Attacker ''Ohka'' was a manned flying bomb that was usually carried underneath a Mitsubishi G4M2e Model 24J "Betty" ...

T-Stoff
T-Stoff (; 'substance T') was a stabilised high test peroxide used in Nazi Germany, Germany during World War II. T-Stoff was specified to contain 80% (occasionally 85%) hydrogen peroxide (H2O2), remainder water, with traces (<0.1%) of stabilisers. Stabilisers used included 0.0025% phosphoric acid, a mixture of phosphoric acid, trisodium phosphate, sodium phosphate and Oxyquinoline, 8-oxyquinoline, and sodium stannate. Uses The decomposition of T-Stoff into hot steam and oxygen caused by the addition of the catalyst Z-Stoff (an aqueous solution of permanganates) was used to drive the split-tube steam catapults which launched the V-1 flying bomb. Similarly generated steam was used to drive the turbopump in the German V-2 rocket, V2 rocket, and the pumps in several other rocket engines. The turbopump was used to transport fuel and oxidizer liquids under pressure to the rocket engine of the V2. Another of T-Stoff's many uses was to be combined as the oxidizer, ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Josef Pöhs
Josef "Joschi" Pöhs (14 March 1912 – 30 December 1943) was a Luftwaffe ace and recipient of the Knight's Cross of the Iron Cross during World War II. The Knight's Cross of the Iron Cross was awarded to recognise extreme battlefield bravery or successful military leadership. Pöhs was attached with the Jagdgeschwader 54 fighter wing until spring of 1942 when he transferred to Erprobungskommando 16, a test unit for the new Messerschmitt Me 163 Komet. Pöhs was killed on 30 December 1943 when his Me 163 was damaged on take-off. When the drop away undercarriage bounced off the ground, it hit the underbelly of the aircraft on rebound, damaging a fuel line containing T-Stoff. This caused the engine to shut down and forced Pöhs to try an attempt to glide back to safety. However, he crashed at Bad Zwischenahn succumbing to injuries he sustained due to exposure to T-Stoff. During his career he was credited with 43 aerial victories. Awards * Flugzeugführerabzeichen * Front Flying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrosive Substance
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen, or hydroxide. Rusting, the formation of red-orange iron oxides, is a well-known example of electrochemical corrosion. This type of corrosion typically produces oxides or salts of the original metal and results in a distinctive coloration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including mechanical strength, appearance, and permeability to liquids and ga ...

Allies Of World War II
The Allies, formally referred to as the United Nations from 1942, were an international Coalition#Military, military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members were the "Four Policemen, Big Four" – the United Kingdom, United States, Soviet Union, and Republic of China (1912–1949), China. Membership in the Allies varied during the course of the war. When the conflict broke out on 1 September 1939, the Allied coalition consisted of the United Kingdom, French Third Republic, France, and Second Polish Republic, Poland, as well as their respective Dependent territory, dependencies, such as British Raj, British India. They were joined by the independent dominions of the British Commonwealth: Canada, Australia, Dominion of New Zealand, New Zealand and Union of South Africa, South Africa. Consequently, the initial alliance resembled Allies of World War I, that of the First World War. As Axis forces began German invasion of ...

Mitsubishi J8M
The Mitsubishi J8M ''Shūsui'' (Japanese: 三菱 J8M 秋水, literally "Autumn Water", used as a poetic term meaning "Sharp Sword", deriving from the swishing sound of a sword) is a Japanese World War II rocket-powered interceptor aircraft closely based on the German Messerschmitt Me 163 ''Komet''. Built as a joint project for both the Navy and the Army Air Services, it was designated J8M (Navy) and Ki-200 (Army). Design and development The J8M1 was intended to be a licence-built copy of the Messerschmitt Me 163 ''Komet'', but difficulties in shipping an example to Japan meant that the aircraft eventually had to be reverse-engineered from a flight operations manual and other limited documentation. A single prototype was tested before the end of World War II. The Japanese were aware of the results of the strategic bombing of Germany, and they knew that the B-29 Superfortress would be bombing Japan and that there would be problems trying to combat this.
