Super Fledermaus
The Super Fledermaus (literally Super Bat), known in Swiss service as the Feuerleitgerät 63, Flt Gt 63 (fire control radar unit 63), is a pulse-radar fire control system, 111 of these systems were in service with the Swiss Air Force from 1965 to 1977. Under the lead of Contraves, the Super Fledermaus fire control system was jointly developed and produced by ten companies. It replaced the Fire control radar Mark VII in Swiss service, and was in turn replaced by the Skyguard system. Function The Flt Gt 63 comprises a towed trailer, a Doppler radar in the E / F-band with a range of 15 kilometers and a pulse Doppler Rader in the J band, again with a 15 kilometer range, it can simultaneously control two Oerlikon 35 mm twin anti-aircraft mountings. In use the system's E/F band search radar monitors the airspace scanning for targets; once targets have been identified the target can be tracked and engaged either visually or by radar. Visual operation (OZ) utilizes electro-optical s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...

Military Equipment Of Switzerland
This is a list of weapons, vehicles and aircraft used by the Swiss Army at present or in the past. Small arms Weapons marked in bold are considered personal equipment of the soldier, who is responsible for their well-functioning and were required to keep them at home until the end of the military service (unless living near an external border of Switzerland). In 2010, the regulation that allowed members of the Swiss militia to keep their assigned personal weapon in their home was amended, and now allows members of the militia to voluntarily deposit their issued firearm in an armory. Between brackets is the number of such weapons in personal equipment as of 31 January 2009. Swiss Army knives are also issued, but are not considered weapons. Individual weapons * Sturmgewehr 90 assault rifle + bayonet (200,000) * Sturmgewehr 07 assault rifle (Swiss Grenadiers, ARD 10, FSK-17, Military Police) * Pistole 75 semi-automatic pistol (30,000) * Pistole 03 semi-automatic pistol ...

Flieger-Flab-Museum
The Flieger Flab Museum (English: Swiss Air Force Museum) is located in the Canton of Zurich in Dübendorf on the grounds of Dübendorf Air Base. In the museum, 40 airplanes and helicopters are displayed, with the collection divided into distinct eras: pioneers and World War I, the 1930s, World War II and the postwar period, the beginning of the jet age, the development of jet fighters, the Cold War, and arms reduction. History The collection was founded in 1972 by the Office for Military Airfields and dedicated to the history of Swiss military aviation and air defense. In 1972–1978, the collection was turned over to the state by the Swiss Federal Office for military airfields. In 1978, for the first time, the public were able to contribute to the collection, which grew steadily over the next few years. Finally, in 1979, the Friends of the Museum of the Swiss air force (VFMF) was formed, initiated by Hans Giger, the Director of the Federal Office for military airfields. D ...

Skyguard Radar
The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves (renamed as ''Rheinmetall Air Defence AG'' following the merger with Rheinmetall in 2009). The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries. Design and development The system uses twin autocannons, firing 35×228mm NATO-standard ammunition. It was originally designated 353 MK and is now designated as the KD series. The same KD series 35mm cannons are used in the Leopard 1 based Gepard and Type 74 tank based Type 87 SPAAG and Marksman self-propelled anti-aircraft guns (SPAAG). The system could be paired with the off-gun (remote) '' Super Fledermaus'' fire control radar, which in the late 1970s was upgraded to the ''Skyguard'' system. The weapons was aimed either directly, by way of an advanced sighting system, or automatically, by locking onto the target with ra ...

Clutter (radar)
Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff and atmospheric turbulences, and can cause serious performance issues with radar systems. Backscatter coefficient What one person considers to be clutter, another may consider to be a target. However, targets usually refer to point scatterers and clutter to extended scatterers (covering many range, angle, and Doppler cells). The clutter may fill a volume (such as rain) or be confined to a surface (like land). In principle, all that is required to estimate the radar return (backscatter) from a region of clutter is a knowledge of the volume or surface illuminated and the echo per unit volume, η, or per unit surface area, σ° (the backscatter coefficient). Clutter-limited or noise-limited radar In addition to any possible clutter there will also always be noise. The total signal competing with th ...

External Ballistics
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field. Gun-launched projectiles may be unpowered, deriving all their velocity from the propellant's ignition until the projectile exits the gun barrel. However, exterior ballistics analysis also deals with the trajectories of rocket-assisted gun-launched projectiles and gun-launched rockets; and rockets that acquire all their trajectory velocity from the interior ballistics of their on-board propulsion system, either a rocket motor or air-breathing engine, both during their boost phase and after motor burnout. External ballistics is also concerned with the free-flight of other projectiles, such as balls, arrows etc. Forces acting on the project ...

Deflection (ballistics)
{{unreferenced, date=May 2008 Deflection shooting is a technique of shooting ahead of a moving target, also known as leading the target, so that the projectile will "intercept" and collide with the target at a predicted point. This technique is only necessary when the target will have significantly displaced its position during the time the projectile would take to reach the target, which can become the case over very long distances (e.g. a long sniper shot), due to fast moving targets (e.g. aerial dogfight against an opposing aircraft, or anti-aircraft fire against passing aircraft), or while using relatively slow projectiles (e.g. a bolt shot from a crossbow, or a basketball thrown to a running teammate). Gyro gunsights developed for aircraft of the Second World War displayed a reticle that compensated for target lead. Modern fighter aircraft have automated deflection sights, where a computer calculates lead and projects the solution onto a head-up display (HUD). The visual a ...

Flakpanzer Gepard
The ''Flugabwehrkanonenpanzer Gepard'' ("anti-aircraft-gun tank 'Cheetah, better known as the Flakpanzer Gepard) is an all-weather-capable German self-propelled anti-aircraft gun (SPAAG). It was developed in the 1960s, fielded in the 1970s, and has been upgraded several times with the latest electronics. It has been a cornerstone of the air defence of the German Army (Bundeswehr) and a number of other NATO countries. In Germany, the Gepard was phased out in late 2010 and replaced by the Wiesel 2 Ozelot ''Leichtes Flugabwehrsystem'' (LeFlaSys) with four FIM-92 Stinger or LFK NG missile launchers. A variant with the MANTIS gun system and LFK NG missiles, based on the GTK Boxer, was also considered. The Gepard has seen combat in the Russo-Ukrainian War. Technology and systems The vehicle is based on the hull of the Leopard 1 tank with a large fully rotating turret carrying the armament—a pair of 35 mm Oerlikon KDA autocannons. Chassis and propulsion The Gepard is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-control Radar
A fire-control radar (FCR) is a radar that is designed specifically to provide information (mainly target azimuth, elevation, range and range rate) to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar. A typical fire-control radar emits a narrow, intense beam of radio waves to ensure accurate tracking information and to minimize the chance of losing track of the target. This makes them less suitable for initial detection of the target, and FCRs are often partnered with a medium-range search radar to fill this role. In British terminology, these medium-range systems were known as tactical control radars. Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and search radar. This works either by havin ...

Swiss Air Force
The Swiss Air Force (german: Schweizer Luftwaffe; french: Forces aériennes suisses; it, Forze aeree svizzere; rm, Aviatica militara svizra) is the air component of the Swiss Armed Forces, established on 31 July 1914 as a part of the army and in October 1936 as an independent service. In peacetime, Dübendorf is the operational air force headquarters. The Swiss Air Force operates from several fixed bases (see current status) but its personnel are also trained to carry out air operations from temporary highway airstrips. In case of crisis or war, several stretches of road are specially prepared for this option. History Early years The first military aviation in Switzerland took the form of balloon transport, pioneered by Swiss balloonist Eduard Spelterini, but by 1914 there was still little official support for an air corps. The outbreak of World War I changed opinions drastically and cavalry officer Theodor Real was charged with forming a flying corps. He commandeered th ...
