Hs 293
The Henschel Hs 293 was a World War II German radio-guided glide bomb. It is the first operational anti-shipping missile, first used unsuccessfully on 25 August 1943 and then with increasing success over the next year, ultimately damaging or sinking at least 25 ships. Allied efforts to jam the radio control link were increasingly successful despite German efforts to counter them. The weapon remained in use through 1944 when it was also used as an air-to-ground weapon to attack bridges to prevent the Allied breakout after D-Day, but proved almost useless in this role. Development The Hs 293 project was started in 1940, based on the "Gustav Schwartz Propellerwerke" pure glide bomb that was designed in 1939. The Schwartz design did not have a terminal guidance system; instead, it used an autopilot to maintain a straight course. It was intended to be launched from a bomber at sufficient distance to keep the aircraft out of range of anti-aircraft fire. A Henschel team, under Dr. ...

Deutsches Technikmuseum
(German Museum of Technology) in Berlin, Germany is a museum of science and technology, and exhibits a large collection of historical technical artifacts. The museum's main emphasis originally was on rail transport, but today it also features exhibits of various sorts of industrial technology. In 2003, it opened both maritime and aviation exhibition halls in a newly built extension. The museum also contains a science center called Spectrum. History The Museum of Traffic and Technology (') was founded in 1982 and assumed the tradition of the Royal Museum of Traffic and Construction (') which was opened in the former station building in 1906. The present-day museum is located on the former freight yard attached to the in the district of Berlin, including two historic roundhouses and several office buildings. Renamed ' in 1996, the exhibition area was gradually expanded. An adjacent new building complex was inaugurated in 2003, topped by a prominent US Air Force Douglas C-47B ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

Precision-guided Munition
A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped. Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence reduction in miss distance) enable a target to be attacked with fewer or smaller bombs. Thus, even if some guided bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be reduced. The advent of precision-guided munitions resulted in the renaming of older, low-technology, bombs as "ungu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fritz X
Fritz X was the most common name for a German guided anti-ship glide bomb used during World War II. ''Fritz X'' was the world's first precision guided weapon deployed in combat and the first to sink a ship in combat. ''Fritz X'' was a nickname used both by Allied and ''Luftwaffe'' personnel. Alternative names include Ruhrstahl SD 1400 X, Kramer X-1, PC 1400X or FX 1400 (the latter, along with the unguided PC 1400 ''Fritz'' nickname, is the origin for the name "Fritz X"). History ''Fritz X'' was a further development of the PC 1400 (''Panzersprengbombe, Cylindrisch'' 1,400 kg) German Wikipedia's WW II PC-series bomb specifications, German for "armor-piercing bomb, cylindrical". armour-piercing high-explosive bomb, itself bearing the nickname ''Fritz''. It was a penetration weapon intended to be used against armored targets such as heavy cruisers and battleships. It was given a more aerodynamic nose, four stub wings, and a box-shaped tail unit consisting of a roughly 12-sid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kehl-Strasbourg Radio Control Link
The Kehl-Straßburg radio control link was a German MCLOS radio control system of World War II. The system was named for Strasbourg, the French/German city on the Rhine and Kehl, at the time a suburb of Strasbourg. It was used by the Fritz X guided bomb and the Henschel Hs 293 guided missile, and would also be trialled in test of the Henschel Hs 298 MCLOS-guidance air-to-air missile. Description The generic term ''Funkgerät'', the source for the ''FuG'' prefix, translates directly into "radio equipment" in English (funk - radio; gerät - equipment), and also prefixed the designations of other various types of German military electronics, like the ''Lichtenstein'' and ''Neptun'' airborne intercept radar series, and the ''Erstling'' IFF radio gear, among others. The ''Kehl-Straßburg'' system combined two units. The dual-axis, single-joystick-equipped ''Funkgerät (FuG 203) Kehl'' series of radio-control transmitter sets, fitted aboard the launch aircraft, were used to send ...

SC500 Bomb
The SC 500 (Sprengbombe-Cylindrisch bomb (other), Sprengbombe Cylindrisch) or ''cylindrical explosive bomb'' in English was a family of general-purpose bombs used by the Luftwaffe during World War II. Design They had three-piece drawn steel bodies with a heavy machined nose cap for armor penetration. At the other end was a base plate, just forward of which the magnesium alloy tail was tack welded onto the body, and also bolted to the tail attachment brace. The bomb was usually filled with a mixture of 40% amatol and 60% TNT, Trotyl, but when used as an anti-shipping bomb it was filled with ''Trialen 105'', a mixture of 15% RDX, hexogen, 70% TNT, Trotyl and 15% aluminium powder. Around the nose of the bomb was a ''kopfring'' - a metal ring, triangular in cross section, designed to prevent ground penetration or to stop forward momentum when hitting water. The bomb could also be fitted with a ''Stabo Spike'' which was an anti-ricochet device that prevented the bomb fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinkel He 111
The Heinkel He 111 is a German airliner and bomber designed by Siegfried and Walter Günter at Heinkel Flugzeugwerke in 1934. Through development, it was described as a "wolf in sheep's clothing". Due to restrictions placed on Germany after the First World War prohibiting bombers, it was presented solely as a civil airliner, although from conception the design was intended to provide the nascent Luftwaffe with a heavy bomber. Perhaps the best-recognised German bomber of World War II due to the distinctive, extensively glazed "greenhouse" nose of the later versions, the Heinkel He 111 was the most numerous Luftwaffe bomber during the early stages of the war. It fared well until it met serious fighter opposition during the Battle of Britain, when its defensive armament was found to be inadequate. As the war progressed, the He 111 was used in a wide variety of roles on every front in the European theatre. It was used as a strategic bomber during the Battle of Britain, a torpedo bo ...

Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the e ...

Walter HWK 109-507
The HWK 109-507 was a liquid-propellant rocket engine developed by Germany during World War II. It was used to propel the Hs 293 anti-ship guided missile. It was produced by Hellmuth Walter Kommanditgesellschaft (HWK). Like other Walter engines it used hydrogen peroxide as a propellant. Missile The Hs293 has been variously described as a missile or as a boosted glide bomb. It consisted of an SC500 bomb casing, fitted with wings, engine and radio control. Control equipment was housed in a rearward extension of the bomb casing but the motor was mounted in a separate housing beneath. It had originally been developed as an unpowered glide bomb, "Gustav Schwartz Propellerwerke", and the engine was added later. After flight tests, a visible tracking flare was also added, in a further rearward extension. As the engine was mounted below the missile fuselage, the exhaust nozzle pointed downwards at 30°, so as to align the line of thrust with the centre of gravity of the missile. The ...
