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, 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 started in 1940, based on the "Gustav Schwartz Propellerwerke" pure glide bomb 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 Herbert Wagner, developed ...

HWK 109-507
Hellmuth Walter (26 August 1900 – 16 December 1980) was a German engineer who pioneered research into rocket engines and gas turbines. His most noteworthy contributions were rocket motors for the Messerschmitt Me 163 and Bachem Ba 349 interceptor aircraft, so-called ''Starthilfe'' jettisonable rocket propulsion units used for a variety of Luftwaffe aircraft during World War II, and a revolutionary new propulsion system for submarines known as air-independent propulsion (AIP). Early life Walter began training as a machinist in 1917 in Hamburg and in 1921 commenced studies in mechanical engineering at the Technische Hochschule in Charlottenburg (now Technische Universität Berlin). He left before completing these studies, however, in order to take up a position at the Stettiner Maschinenbau AG Vulcan, a major shipyard. Walter's experience with marine engines here led him to become interested in overcoming some of the limitations of the internal combustion engine. He reason ...

Jackscrew
A jackscrew, or screw jack, is a type of jack that is operated by turning a leadscrew. It is commonly used to lift moderate and heavy weights, such as vehicles; to raise and lower the horizontal stabilizers of aircraft; and as adjustable supports for heavy loads, such as the foundations of houses. Description A screw jack consists of a heavy-duty vertical screw with a load table mounted on its top, which screws into a threaded hole in a stationary support frame with a wide base resting on the ground. A rotating collar on the head of the screw has holes into which the handle, a metal bar, fits. When the handle is turned clockwise, the screw moves further out of the base, lifting the load resting on the load table. In order to support large load forces, the screw is usually formed with Acme threads. Advantages An advantage of jackscrews over some other types of jack is that they are ''self-locking'', which means when the rotational force on the screw is removed, it will remain ...

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 and canards) 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 ...

Precision-guided Munition
A precision-guided munition (PGM), also called a smart weapon, smart munition, or smart bomb, is a type of weapon system that integrates advanced guidance and control systems, such as Global Positioning System, GPS, laser guidance, or Infrared search and track, infrared sensors, with various types of Ammunition, munitions, typically Missile, missiles or Shell (projectile), artillery shells, to allow for high-accuracy strikes against designated Targeting (warfare), targets. PGMs are designed to precisely hit a predetermined target, typically with a margin of error (or circular error probable, CEP) that is far smaller than conventional unguided munitions. Unlike unguided munitions, PGMs use active or passive Control system, control mechanisms capable of steering the weapon towards its intended target. PGMs are capable of mid-flight course corrections, allowing them to adjust and hit the intended target even if conditions change. PGMs can be deployed from various platforms, includi ...

Fritz X
Fritz X was a German guided anti-ship glide bomb used during World War II. Developed alongside the Henschel Hs 293, ''Fritz X'' was one of the first precision guided weapons deployed 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):de:Deutsche Abwurfmunition des Zweiten Weltkrieges#Panzersprengbombe (PC und PD), German Wikipedia's WW II PC-series bomb specifications, German for "armour-piercing bomb, cylindrical". armour-piercing high-explosive bomb, itself bearing the nickname ''Fritz''. It was a penetration weapon intended to be used against armoured targets such as heavy cruisers and battleships. It was given a more aerodynamic nose, four stub ...

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 was a ''Sprengbombe Cylindrisch'' ("cylindrical explosive bomb") family of 500 kg weight general-purpose bombs used by the Luftwaffe of Nazi Germany during World War II. Design The bombs 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% Trotyl, but when used as an anti-shipping bomb it was filled with ''Trialen 105'', a mixture of 15% hexogen, 70% Trotyl and 15% aluminium powder. Around the nose of the bomb could be fitted an optional ''kopfring'' - a metal ring, triangular in cross section, designed to prevent ground penetration or to stop forward momentum when hitting water (to prevent the bomb from skipping off the water). The bomb could also be fitted with a ''Stabo Spike'' which was a device ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinkel He 111
The Heinkel He 111 is a German airliner and medium 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 to ...

Rocket Engine
A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed Jet (fluid), jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket. However, non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum, and they can achieve great speed, beyond escape velocity. Vehicles commonly propelled by rocket engines include missiles, Rocket-assisted projectile, artillery shells, ballistic missiles and rockets of any size, from tiny Rocket (firework), fireworks to Rocket (weapon), man-sized weapons to huge Space vehicle, spaceships. 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 ...

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. ...

Henschel
Henschel & Son () 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 at the Kassel plant. In Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
