Python 5
The Rafael Python (stylized all uppercase; ''פיתון'') is a family of air-to-air missiles (AAMs) built by the Israeli weapons manufacturer Rafael Advanced Defense Systems, formerly RAFAEL Armament Development Authority. Originally starting with the ''Shafrir'' (, loosely translated as a dome, or a protective cloak – but also similar sounding to Dragonfly, a male form of inflection for Damselfly (שפירית)) series, the ''Shafrir-1'' missile was developed in 1959, followed by the ''Shafrir-2'' in early 1970s. Subsequently, the missiles were given the western name of "''Python''" by the parent company for export purposes, starting with the ''Python-3'' in 1978. Since then, it has been further developed and evolved into the ''Python-4'', ''Python-5'', ''Derby'' and also, the SPYDER, an advanced ground-based air-defence system. Currently, the missiles are in service with the armed forces of over fifteen countries from around the world. Design and development In the 1950s, ...

Air-to-air Missile
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft (including unmanned aircraft such as cruise missiles). AAMs are typically powered by one or more rocket motors, usually solid-fuel rocket, solid fueled but sometimes liquid-fuel rocket, liquid fueled. Ramjet engines, as used on the Meteor (missile), Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of around 30 km to 40 km maximum are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or LRAAMs), which ...

Six-Day War
The Six-Day War, also known as the June War, 1967 Arab–Israeli War or Third Arab–Israeli War, was fought between Israel and a coalition of Arab world, Arab states, primarily United Arab Republic, Egypt, Syria, and Jordan from 5 to 10June 1967. Military hostilities broke out amid poor relations between Israel and its Arab neighbors, which had been observing the 1949 Armistice Agreements signed at the end of the 1948 Arab–Israeli War, First Arab–Israeli War. In 1956, regional tensions over the Straits of Tiran (giving access to Eilat, a port on the southeast tip of Israel) escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Israeli passage through the Suez Canal and Straits of Tiran, Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Borders of Israel#Border with Egypt, Egypt ...

Israeli Air Force
The Israeli Air Force (IAF; , commonly known as , ''Kheil HaAvir'', "Air Corps") operates as the aerial and space warfare branch of the Israel Defense Forces (IDF). It was founded on May 28, 1948, shortly after the Israeli Declaration of Independence. , Aluf Tomer Bar has been serving as the Air Force commander. The Israeli Air Force was established using commandeered or donated civilian aircraft and obsolete and surplus World War II combat aircraft. Eventually, more aircraft were procured, including Boeing B-17s, Bristol Beaufighters, de Havilland Mosquitoes and P-51D Mustangs. The Israeli Air Force played an important part in Operation Kadesh, Israel's part in the 1956 Suez Crisis, dropping paratroopers at the Mitla Pass. On June 5, 1967, the first day of the Six-Day War, the Israeli Air Force performed Operation Focus, debilitating the opposing Arab air forces and attaining air supremacy for the remainder of the war. Shortly after the end of the Six-Day War, Egypt i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPYDER
The SPYDER ("Surface-to-air Python and Derby") is an Israeli short and medium range mobile air defence system developed by Rafael Advanced Defense Systems with assistance from Israel Aerospace Industries (IAI). Rafael is the prime contractor and IAI is the major subcontractor for the SPYDER program. This system achieved a notable milestone in 2005 when missiles were fired against test targets in Shdema, Israel and scored direct hits. Since then, it has been showcased in multiple military exhibitions throughout the world. The SPYDER is a low-level, quick-reaction surface-to-air missile system capable of engaging aircraft, helicopters, unmanned air vehicles, drones, cruise missiles and precision-guided munitions. It provides air defence for fixed assets and for point and area defence for mobile forces in combat areas. The system is fitted atop a Tatra truck, a Mercedes-Benz Actros truck, a MAN TGS truck, Scania P-series truck, Dongfeng truck, or a TELAR. It implements the Py ...

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies (which constitute the other odonatan suborder, Epiprocta) but are usually smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. Damselflies have existed since the Late Jurassic, and are found on every continent except Antarctica. All damselflies are predatory insects: both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but their dependence on fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflection
In linguistic Morphology (linguistics), morphology, inflection (less commonly, inflexion) is a process of word formation in which a word is modified to express different grammatical category, grammatical categories such as grammatical tense, tense, grammatical case, case, grammatical voice, voice, grammatical aspect, aspect, grammatical person, person, grammatical number, number, grammatical gender, gender, grammatical mood, mood, animacy, and definiteness. The inflection of verbs is called ''grammatical conjugation, conjugation'', while the inflection of nouns, adjectives, adverbs, etc. can be called ''declension''. An inflection expresses grammatical categories with affixation (such as prefix, suffix, infix, circumfix, and transfix), apophony (as Indo-European ablaut), or other modifications. For example, the Latin verb ', meaning "I will lead", includes the suffix ', expressing person (first), number (singular), and tense-mood (future indicative or present subjunctive). Th ...

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of dragonflies are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterised by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural coloration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan, though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, al ...

Letter Case
Letter case is the distinction between the letters that are in larger uppercase or capitals (more formally ''majuscule'') and smaller lowercase (more formally '' minuscule'') in the written representation of certain languages. The writing systems that distinguish between the upper- and lowercase have two parallel sets of letters: each in the majuscule set has a counterpart in the minuscule set. Some counterpart letters have the same shape, and differ only in size (e.g. ), but for others the shapes are different (e.g., ). The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are typically treated identically when sorting in alphabetical order. Letter case is generally applied in a mixed-case fashion, with both upper and lowercase letters appearing in a given piece of text for legibility. The choice of case is often denoted by the grammar of a language or by the conventions of a particular discipline. In ortho ...

Sukhoi Su-25
The Sukhoi Su-25 ''Grach'' ( ('' rook''); NATO reporting name: Frogfoot) is a subsonic, single-seat, twin-engine jet aircraft developed in the Soviet Union by Sukhoi. It was designed to provide close air support for Soviet Ground Forces. The first prototype made its maiden flight on 22 February 1975. After testing, the aircraft went into series production in 1978 in Tbilisi in the Georgian Soviet Socialist Republic. Early variants included the Su-25UB two-seat trainer, the Su-25BM for target-towing, and the Su-25K for export customers. Some aircraft were upgraded to the Su-25SM standard in 2012. The Su-25T and the Su-25TM (also known as the Su-39) were further developments, not produced in significant numbers. The Su-25, and the Su-34, were the only armoured, fixed-wing aircraft in production in 2007.Gordon and Dawes 2004. Su-25s are in service with Russia, other CIS members, and export customers. Production of the Su-25 ended in 2010 in Georgia. Attempts continue to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
