Arado E.381
The Arado E.381 (''Kleinstjäger'' – "smallest fighter") was a proposed parasite fighter aircraft. Conceived by ''Arado Flugzeugwerke'' in December 1944 for Germany's Luftwaffe during World War II, the E.381 was to have been carried aloft by and launched from an Arado Ar 234 "mother" aircraft. It would then have activated its rocket engine, which would have propelled it to attack Allied (mainly American and British) bombers. Development was cancelled due to lack of funds and official support.Krantzhoff, pp. 153–156Kay and Smith, p. 388Albrecht, p.101 There were three proposed variants; each had fuel capacity for only two target runs, after which the pilot would have been required to glide without power to a landing on underbelly skids. To survive close pursuits, the E.381 was designed with the narrowest frontal cross-section possible to increase its chances of surviving shots from the front. This also forced the pilot to lie in a prone position. The cross-section was , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technikmuseum Speyer
The Technik Museum Speyer is a technology museum in Speyer (Rhineland-Palatinate), Germany. 208 History The museum was opened in 1991 as a sister museum of the Auto & Technik Museum Sinsheim and is run by a registered alliance called "Auto & Technik Museum Sinsheim e.V.". , it has more than 2,000 exhibits and an exhibition area of more than 150,000 m² (indoors and outdoors). It attracts more than half a million visitors per year. In addition to the exhibitions, the museum also sports a 22 m x 27 m giant IMAX Dome theatre. Walk-in exhibits In spring 2002, Lufthansa donated a retired Boeing 747-200 aircraft, which is now accessible to visitors. In April 2008, a Soviet/Russian Buran spacecraft, OK-GLI, was transported to the Technik Museum and is now another walk-in exhibit. Other walk-in highlights are an Antonov An-22 and several other aircraft types, locomotives, the houseboat ''Sean O'Kelley'' of The Kelly Family, and submarine ''U9'' of the German Navy.

Henschel & Son
Henschel & Son (german: Henschel und Sohn) was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons. Georg Christian Carl Henschel founded the factory in 1810 at Kassel. His son Carl Anton Henschel founded another factory in 1837. In 1848, the company began manufacturing locomotives. The factory became the largest locomotive manufacturer in Germany by the 20th century. Henschel built 10 articulated steam trucks, using Doble steam designs, for Deutsche Reichsbahn railways as delivery trucks. Several cars were built as well, one of which became Hermann Göring's staff car. In 1935 Henschel was able to upgrade its various steam locomotives to a high-speed Streamliner type with a maximum speeds of up to by the addition of a removable shell over the old steam locomotive. In 1918, Henschel began the production of gearboxes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drogue Parachute
A drogue parachute is a parachute designed for deployment from a rapidly-moving object. It can be used for various purposes, such as to decrease speed, to provide control and stability, or as a pilot parachute to deploy a larger parachute. Vehicles that have used drogue parachutes include multi-stage parachutes, aircraft, and spacecraft recovery systems. The drogue parachute was invented by the Russian professor and parachute specialist Gleb Kotelnikov in 1912, who also invented the knapsack parachute. The Soviet Union introduced its first aircraft fitted with drogue parachutes during the mid 1930s; use of the technology expanded during and after the Second World War. A large number of jet-powered aircraft have been furnished with drogue parachutes, including the Boeing B-52 Stratofortress strategic bomber and the Eurofighter Typhoon multirole aircraft; they were also commonly used within crewed space vehicle recovery programmes, including Project Mercury and Project Gemi ...

Gliding
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities to mak ...

Walter HWK 109-509
The Walter HWK 109-509 was a German liquid-fuel bipropellant rocket engine that powered the Messerschmitt Me 163 Komet and Bachem Ba 349 aircraft. It was produced by Hellmuth Walter Kommanditgesellschaft (HWK) commencing in 1943, with licensed production by the Heinkel firm's facilities in Jenbach, Austria. Design and development Early versions of the Me 163 had been powered by an earlier design running on a "cold engine" fueled with Z-Stoff. This fuel tended to clog the jets in the combustion chamber, causing fluctuations in power and potentially explosions. Worse, however, was the fact that the engine could not be throttled, and when the aircraft leveled off after its climb to altitude it quickly accelerated to speeds that caused serious compressibility issues. The RLM demanded that a version be developed with a throttle. During this period Walter had also been working with a new fuel known as C-Stoff that gave off significant heat and was thus known as the "hot engine". ...

Armament
A weapon, arm or armament is any implement or device that can be used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target. While ordinary objects – sticks, rocks, bottles, chairs, vehicles – can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs, axes and swords, to complicated modern firearms, tanks, intercontinental ballistic missiles, biological weapons, and cyberweapons. Something that has been re-purposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser. History The use of weapons is a major driver of cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
