Lorenz Beam
The Lorenz beam was a blind-landing radio navigation system developed by C. Lorenz AG in Berlin. The first system had been installed in 1932 at Berlin-Tempelhof Central Airport, followed by Dübendorf in Switzerland (1934) and others all over the world. The Lorenz company referred to it simply as the ''Ultrakurzwellen-Landefunkfeuer'', German for "ultra-short-wave landing radio beacon", or ''LFF''. In the UK it was known as ''Standard Beam Approach'' (SBA). Prior to the start of the Second World War the Germans deployed the system at many Luftwaffe airfields in and outside Germany and equipped most of their bombers with the radio equipment needed to use it. It was also adapted into versions with much narrower and longer-range beams that was used to guide the bombers on missions over Britain, under the name Knickebein and X-Gerät. Beam navigation provides a single line in space, making it useful for landing or enroute navigation, but not as a general purpose navigation system th ...

Instrument Landing System
In aviation, the instrument landing system (ILS) is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. In its original form, it allows an aircraft to approach until it is over the ground, within a of the runway. At that point the runway should be visible to the pilot; if it is not, they perform a missed approach. Bringing the aircraft this close to the runway dramatically increases the range of weather conditions in which a safe landing can be made. Other versions of the system, or "categories", have further reduced the minimum altitudes, runway visual ranges (RVRs), and transmitter and monitoring configurations designed depending on the normal expected weather patterns and airport safety requirements. ILS uses two directional radio signals, the ''localizer'' (108 to 112 MHz frequency), which provides horizontal guidance, and the ''glideslope'' (329.15 to 335 MHz frequency ...

Reginald Victor Jones
Reginald Victor Jones , FRSE, LLD (29 September 1911 – 17 December 1997) was a British physicist and scientific military intelligence expert who played an important role in the defence of Britain in by solving scientific and technical problems, and by the extensive use of deception throughout the war to confuse the Germans. Early life Reginald Jones was born in Herne Hill, south London, on 29 September 1911. He was educated at Alleyn's School, Dulwich, and Wadham College, Oxford, where he studied Natural Sciences. In 1932 he graduated with First Class honours in physics and then, working in the Clarendon Laboratory, completed his DPhil in 1934. Subsequently, he took up a Skynner Senior Studentship in Astronomy at Balliol College, Oxford. Assistant Director of Intelligence (Science) In 1936 Jones took up the post at the Royal Aircraft Establishment, Farnborough, a part of the Air Ministry. Here he worked on the problems associated with defending Britain from an air attac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Steinbock
Operation Steinbock (german: Unternehmen Steinbock), sometimes called the Baby Blitz, was a strategic bombing campaign by the German Air Force (the Luftwaffe) during the Second World War. It targeted southern England and lasted from January to May 1944. Steinbock was the last strategic air offensive by the German bomber arm during the conflict. In late 1943, the Allied Combined Bomber Offensive was gathering momentum against Germany. The Allied air forces were conducting a strategic bombing campaign day and night against German industrial cities. In retaliation, Adolf Hitler ordered the Luftwaffe to prepare a bombing operation against the United Kingdom. The bombing offensive also served as propaganda value for the German public and domestic consumption. The operation ran parallel to Bomber Command's campaign against Berlin (November 1943 – March 1944). The Luftwaffe assembled 474 bomber aircraft for the offensive. The attacks were mainly aimed at and around the Greater Lond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bomber
A bomber is a military combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry (such as bombs), launching aerial torpedo, torpedoes, or deploying air-launched cruise missiles. The first use of bombs dropped from an aircraft occurred in the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Second World War by all major airforces causing devastating damage to cities, towns, and rural areas. The first purpose built bombers were the Italy, Italian Caproni Ca 30 and United Kingdom, British Bristol T.B.8, both of 1913. Some bombers were decorated with nose art or victory markings. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure or reduci ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond-Dunmore System
The Diamond-Dunmore system was an early blind landing system developed by Harry Diamond and Francis Dunmore at the National Bureau of Standards in the late 1920s. It was similar to the beam landing systems being developed in the UK and Germany shortly thereafter, but had the added advantage that the directional signal was automatically decoded and displayed on a cockpit indicator, rather than requiring the attention of a radio operator. It also added an optional vertical guidance system to provide a glideslope indication. In spite of the advanced nature of the system, or perhaps because of it, the system does not appear to have been widely used. In contrast, the simpler Lorenz system was widely deployed in Europe. Description The lateral guidance system used two signals on a single carrier frequency around 330 kHz that was amplitude modulated at slightly different frequencies, 65 and 86.7 Hz. The two signals were broadcast from a crossed coil antenna placed at the far e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neon Lamps
A neon lamp (also neon glow lamp) is a miniature gas discharge lamp. The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode). When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces an orange glow discharge. The glowing portion in the lamp is a thin region near the cathode; the larger and much longer neon signs are also glow discharges, but they use the positive column which is not present in the ordinary neon lamp. Neon glow lamps were widely used as indicator lamps in the displays of electronic instruments and appliances. They are still sometimes used for their electrical simplicity in high-voltage circuits. History Neon was discovered in 1898 by William Ramsay and Morris W. Travers. The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers la ...

Control Tower
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advis ...

Glide Slope
Instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path of descent", according to ''Article 1.106'' of the ITU Radio Regulations (ITU RR).ITU Radio Regulations, Section IV. Radio Stations and Systems – Article 1.106, definition: ''instrument landing system (ILS)'' Principle of operation A glide slope station uses an antenna array sited to one side of the runway touchdown zone. The GS signal is transmitted on a carrier signal using a technique similar to that for the localizer. The centre of the glide slope signal is arranged to define a glide path of approximately 3° above horizontal (ground level). The beam is 1.4° deep (0.7° below the glide-path centre and 0.7° above). The pilot (or the autopilot, if using autoland) controls the aircraft so that the glide slope indicator r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marker Beacon
A marker beacon is a particular type of VHF radio beacon used in aviation, usually in conjunction with an instrument landing system (ILS), to give pilots a means to determine position along an established route to a destination such as a runway. According to ''Article 1.107'' of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) a marker beacon is defined as "a transmitter in the aeronautical radionavigation service which radiates vertically a distinctive pattern for providing position information to aircraft". History From the 1930s until the 1950s, markers were used extensively along airways to provide an indication of an aircraft's specific position along the route, but from the 1960s they have become increasingly limited to ILS approach installations. They are now very gradually being phased out of service, especially in more developed parts of the world, as GPS and other technologies have made marker beacons increasingly redundant.
