Hagelkorn
The Blohm & Voss BV 246 ''Hagelkorn'' (German language: "Hailstone") was a guided glide bomb developed to bomb specific targets (bridges, ships, etc.) once it was released. History This glider was designed by Richard Vogt, at first under the designation of BV 226, which was later changed to its definitive designation BV 246 on December 12, 1943. It was intended to be dropped from a Ju 88 or a Heinkel He 111 bomber, either of which could carry three of the weapons, and was to be dropped from a height of at a speed of , giving it a range of up to . In a slight dive the Bv 226 could reach a speed of . The construction of the BV 246 avoided the usual aircraft techniques and strategic materials, so it could be mass-produced. It had clean aerodynamics, with high aspect ratio wings that made possible a glide ratio of 25:1. The wings were made of magnesite cement, formed around a steel spar.Pohlmann, Hermann; ''Chronik Eines Flugzeugwerkes 1932-1945'', Motorbuch, 1979, pp.199-20 ...

Blohm & Voss BV 950
The Blohm & Voss BV 950 was an anti-shipping air-launched glide torpedo developed in two variants, the L10 ''Friedensengel'' and L11 ''Schneewittchen''. Although several hundreds were manufactured during development and trials conducted, neither type entered service. Design The device comprised a small upper body with wings and tail, clamped on top of an air-launched torpedo. In operation, it was dropped by an attacking aircraft from a safe altitude and distance, gliding down towards the target vessel and, as it approached the target, a timed fuse opened a small parachute which was attached to the glider body. It continued down and impacted the water a short distance from the target. When the torpedo met the surface of the water, the glider body automatically detached and was pulled back out of the way by the parachute, while the torpedo motor started and drove it to impact its target. The L 10 was designed for a propeller powered aircraft cruising at around . The L 11 was devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hailstone
Hail is a form of solid precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures. Unlike other forms of water ice precipitation, such as graupel (which is made of rime ice), ice pellets (which are smaller and translucent), and snow (which consists of tiny, delicately crystalline flakes or needles), hailstones usually measure between and in diameter. The METAR reporting code for hail or greater is GR, while smaller hailstones and graupel are coded GS. Hail is possible within most thunderstorms (as it is produced by cumulonimbus), as well as within of the parent storm. Hail formation requires environments of strong, upward motion of air within the parent thunderstorm (similar to tornadoes) and lowered heights of the freezing le ...

Blohm & Voss BV 143
The Blohm & Voss BV 143 was an early prototype rocket-assisted glide bomb developed by the German Luftwaffe during World War II. Design Blohm & Voss designers began to consider airborne missiles late in 1938, even before the outbreak of war. First of these to be developed was the Bv 143, a glide bomb with rocket booster. Trials began in 1939. By 1941, Allied merchant ships were slow and easy targets for German coastal bombers, but were proving increasingly well-equipped with anti-aircraft artillery, making short-range attacks prohibitively costly. Interest was raised in the development of a stand off weapon to engage unarmored merchant ships from beyond the range of the Bofors 40 mm gun. The BV 143 was one of several stand off bomb and missile designs researched by the Blohm & Voss Naval Engineering Works for this anti-shipping role. The Bv 143 was designed to be air-dropped from beyond the range of antiaircraft guns, glide towards the target, engage its solid rocket motor bel ...

Air-to-surface
An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed. Guidance for air-to-surface missiles is typically via laser guidance, infrared guidance, optical guidance or via satellite guidance signals. The type of guidance depends on the type of target. Ships, for example, may be detected via passive radar or active radar homing, less effective against multiple, small, fast-moving land targets. There is some cross-over between air-to-surface missiles and surface-to-surface missiles. For example, there was an air-launched version of the Tomahawk missile, sup ...

Ministry Of Aviation (Germany)
The Ministry of Aviation (german: Reichsluftfahrtministerium, abbreviated RLM) was a government department during the period of Nazi Germany (1933–45). It is also the original name of the Detlev-Rohwedder-Haus building on the Wilhelmstrasse in central Berlin, Germany, which today houses the German Finance Ministry (german: Bundesministerium der Finanzen). The Ministry was in charge of development and production of all aircraft developed, designed and built in Germany during the existence of the Third Reich, overseeing all matters concerning both military and civilian designs – it handled military aviation matters as its top priority, particularly for the Luftwaffe. As was characteristic of government departments in the Nazi era, the Ministry was personality-driven and formal procedures were often ignored in favour of the whims of the Minister, ''Reichsmarschall'' Hermann Göring. As a result, early successes in aircraft development progressed only slowly and erratically dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided Bombs
A guided bomb (also known as a smart bomb, guided bomb unit, or GBU) is a precision-guided munition designed to achieve a smaller circular error probable (CEP). The creation of precision-guided munitions resulted in the retroactive renaming of older bombs as unguided bombs or "dumb bombs". Guidance Guided bombs carry a guidance system which is usually monitored and controlled from an external device. A guided bomb of a given weight must carry fewer explosives to accommodate the guidance mechanisms. Radio The Germans were first to introduce Precision Guided Munitions (PGMs) in combat, using the 1,400-kg (3,100 lb) MCLOS-guidance Fritz X to successfully attack the Italian battleship ''Roma'' in September 1943. The closest Allied equivalents were the 1,000-lb (454 kg) AZON (AZimuth ONly), used in both Europe and the CBI Theater, and the US Navy's Bat, primarily used in the Pacific Theater of World War II which used autonomous, on-board radar guidance.

Blohm & Voss BV 40
The Blohm & Voss BV 40 was a German glider fighter designed to attack Allied bomber formations during the time of the bombing raids over Nazi Germany. Design The BV 40 was the smallest glider that could accommodate an armoured cockpit and two cannon with limited ammunition. By eliminating the engine and lying the pilot in a prone position (i.e. on his front), the cross-sectional area of the fuselage was much reduced, making the BV 40 harder for bomber gunners to hit. The plane was designed to use non-strategic materials and to be built in as short a time as possible by non-skilled workers. The fuselage was constructed almost entirely of wood. It was of conventional layout, the glider had a high-mounted, straight untapered wing with a similarly-shaped tailplane mounted on the fin just above the fuselage. The pilot lay prone in an armoured steel cockpit in the nose of the aircraft. The front steel plate was thick, and was fitted with a windscreen of thick, armoured glass that g ...

VB-6 Felix
The VB-6 Felix was a precision-guided munition developed by the United States during World War II. It used an infrared seeker to attack targets like blast furnaces or the metal roofs of large factories. The war ended before it could be used operationally. History Created by the National Defense Research Committee, Felix relied on infrared to detect and home on heat-emitting targets in clear weather;Ordway and Wakeford 1960, p.124. blast furnaces were considered a particularly practical target for such a weapon, as were the reflective metal roofs of factory buildings. It was this property which earned the weapon its name, after the ability of cats to see in the dark; Felix the Cat was an extremely popular cartoon character at the time. Felix was a 1000-pound (454 kg) general purpose (GP) bomb with an infrared seeker in the nose and octagonal guidance fins in the tail. Unlike other weapons, such as the German Fritz X, Felix was autonomous once launched, although there was a fl ... [...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] |
GB-8
} The GB-1, also known as the "Grapefruit bomb" and as XM-108,379th 2000 p.39. was a glide bomb produced by Aeronca Aircraft for the United States Army Air Forces during World War II. Intended to allow bombers to release bombs from outside the range of enemy defenses, over one thousand GB-1s were used in combat before the end of the war. Design and development The U.S. Army Air Corps – which would later become the U.S. Army Air Forces – initiated development of a glide bomb design in March 1941.Ordway and Wakeford 1960, p.119. Intended to allow bombers to stand off outside the range of enemy flak while releasing their bombload, while also potentially allowing for more precise targeting due to the shallow glide path the bomb would follow, the design resulted in three prototypes; one developed by Aeronca designated GB-1; a design by Bellanca designated GB-2, and the Timm Aircraft-designed GB-3.Parsch 2003 The GB-1 mated a wing and twin-tail empennage of conventional small-ai ...

GB-4
GB-4 (Glide Bomb No.4) was a precision guided munition developed by the United States during World War II. GB-4s used a television guidance system with the weapon being steered by a TV bombardier operating a joystick in the launch aircraft. The first GB-4s (then known as MX-607s) were tested at Eglin Air Force Base during August of 1943. During testing the GB-4's circular error probable accuracy was found to be . The type was ordered into production on the 15 January 1944. Although approved for operational use, the typed suffered from reliability problems throughout testing. The GB-4 was briefly used in combat by the 388th Bomber Group, based in eastern England, but its performance was deemed unsatisfactory. 1,200 GB-4's were delivered to the USAAF however poor combat results lead to a decision to halt further deliveries in February 1945.
