Airwolf (helicopter)
''Airwolf'' is the helicopter from the 1980s American television series of the same name. Its fictional features included stratospheric ceiling, stealth noise signature, a wide range of weapons and supersonic speed. The ''Airwolf'' helicopter was a conventional Bell 222 helicopter modified by attaching some film props. Bell 222 example The flying ''Airwolf'' was derived from a Bell 222, a twin-turboshaft helicopter produced for the civilian market and typically employed for corporate, emergency medical or utility transport missions, with seating for up to 10, including the pilot. The airframe used for ''Airwolf'' was serial number 47085 (registration number N3176S), of the initial production version, sometimes unofficially called a Bell 222A. During filming of the series the helicopter was owned by JetCopters Inc. in Van Nuys, California. After the show was canceled, the modifications were removed from the aircraft and are now owned by a private collector. The helicopter w ...

Sevierville, Tennessee
Sevierville ( ) is a city in and the county seat of Sevier County, Tennessee, located in eastern Tennessee. The population was 17,889 at the 2020 United States Census. History Native Americans of the Woodland period were among the first human inhabitants of what is now Sevierville. They arrived some time around 200 A.D. and lived in villages scattered around the area known as Forks-of-the-River. Between 1200 and 1500 A.D., during the Dallas phase of the Mississippian period, a group of Native Americans established McMahan Mound Site, a relatively large village centered on a platform mound and surrounded by a palisade just above the confluence of the West Fork and the Little Pigeon River. This mound was approximately high and across. An excavation in 1881 unearthed burial sites, arrowheads, a marble pipe, glass beads, pottery, and engraved objects. At the time of this first excavation, the mound was located on a farm owned by the McMahan family, and was thus given the name "M ...

Star Trek
''Star Trek'' is an American science fiction media franchise created by Gene Roddenberry, which began with the eponymous 1960s television series and quickly became a worldwide pop-culture phenomenon. The franchise has expanded into various films, television series, video games, novels, and comic books. With an estimated $10.6 billion in revenue, it is one of the most recognizable and highest-grossing media franchises of all time. The franchise began with ''Star Trek: The Original Series'', which debuted in the US on September 8, 1966 and aired for three seasons on NBC. It was first broadcast on September 6, 1966 on Canada's CTV network. It followed the voyages of the crew of the starship USS ''Enterprise'', a space exploration vessel built by the United Federation of Planets in the 23rd century, on a mission "to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before". In creating ''Star Trek'', Roddenberry w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photon Torpedo
The '' Star Trek'' fictional universe contains a variety of weapons, ranging from missiles (the classic photon torpedo) to melee (primarily used by the Klingons, a race of aliens in the ''Star Trek'' universe). The ''Star Trek'' franchise consists primarily of several multi-season television shows and a dozen movies, as well as various video games and inspired merchandise. Many aspects of the fictional universe impact modern popular culture, especially the lingo and the idea of a spacecraft launching space torpedoes and firing lasers, and have had a wide influence in the late 20th to early 21st century. ''Star Trek'' is popular enough that its science fiction concepts have even been studied by real scientists, and NASA described its science in relation to the real world as "entertaining combination of real science, imaginary science gathered from lots of earlier stories, and stuff the writers make up week-by-week to give each new episode novelty." For example, NASA noted that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM-9 Sidewinder
The AIM-9 Sidewinder (where "AIM" stands for "Air Intercept Missile") is a short-range air-to-air missile which entered service with the US Navy in 1956 and subsequently was adopted by the US Air Force in 1964. Since then the Sidewinder has proved to be an enduring international success, and its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13 (AA-2 'Atoll'), a reverse-engineered copy of the AIM-9B, was also widely adopted by a number of nations. Low-level development started in the late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket. This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile. Originally a tail-chasing system, early models saw extensive use during the Vietnam War but had a low success rate. This led to all-aspect capabilities in ...

AGM-114 Hellfire
The AGM-114 Hellfire is an air-to-ground missile (AGM) first developed for anti-armor use, later developed for precision drone strikes against other target types, especially high-value targets. It was originally developed under the name '' Heliborne laser, fire-and-forget missile'', which led to the colloquial name "Hellfire" ultimately becoming the missile's formal name. It has a multi-mission, multi-target precision-strike ability and can be launched from multiple air, sea, and ground platforms, including the Predator drone. The Hellfire missile is the primary class air-to-ground precision weapon for the armed forces of the United States and many other nations. It has also been fielded on surface platforms in the surface-to-surface and surface-to-air roles. Description Most variants are laser-guided, with one variant, the AGM-114L "Longbow Hellfire", being radar-guided. Laser guidance can be provided either from the launcher, such as the nose-mounted opto-electronics of the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-65 Maverick
The AGM-65 Maverick is an air-to-ground missile (AGM) designed for close air support. It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities. Development began in 1966 at Hughes Aircraft Company as the first missile to use an electronic contrast seeker. It entered service with the United States Air Force in August 1972. Since then, it has been exported to more than 30 countries and is certified on 25 aircraft. The Maverick served during the Vietnam, Yom Kippur, Iran–Iraq, and Persian Gulf Wars, along with other smaller conflicts, destroying enemy forces and installations with varying degrees of success. Since its introduction into service, numerous Maverick versions had been designed and produced using electro-optical, laser, and imaging infrared guidance systems. The AGM-65 has two types of warhead: one has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lifting Body
A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing. Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic and hypersonic flight, or spacecraft re-entry. All of these flight regimes pose challenges for proper flight safety. Lifting bodies were a major area of research in the 1960s and 70s as a means to build a small and lightweight crewed spacecraft. The US built a number of lifting body rocket planes to test the concept, as well as several rocket-launched re-entry vehicles that were tested over the Pacific. Interest waned as the US Air Force lost interest in the crewed mission, and major development ended ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sponson
Sponsons are projections extending from the sides of land vehicles, aircraft or watercraft to provide protection, stability, storage locations, mounting points for weapons or other devices, or equipment housing. Watercraft On watercraft, a sponson is a projection that extends outward (usually from the hull, but sometimes other parts of the vessel) to improve stability while floating, or to act as a securing point for other equipment. Vessels with unstable body shapes or unevenly distributed weight are likely to feature sponsons to help prevent capsizing or other instabilities. On many vessels, these projections from the main body of the vessel can be attached and removed quickly and fairly easily. Canoes and kayaks sometimes feature sponson attachments as well, for stability in rough waters. These differ from outriggers, which extend a significant distance away from the body of the craft, and are employed on craft designed for open waters. A sponson's terminus is close to the cr ...

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Wolf In Sheep's Clothing
A wolf in sheep's clothing is an idiom of Biblical origin used to describe those playing a role contrary to their real character with whom contact is dangerous, particularly false teachers. Much later, the idiom has been applied by zoologists to varying kinds of predatory behaviour. A fable based on it has been falsely credited to Aesop's Fables, Aesop and is now numbered 451 in the Perry Index. The confusion has arisen from the similarity of the theme with fables of Aesop concerning wolves that are mistakenly trusted by shepherds; the moral drawn from these is that one's basic nature eventually shows through the disguise. Origin and variants The phrase originates in the Sermon on the Mount by Jesus recorded in the Christian New Testament: ''Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves'' (Matthew 7:15, Gospel of Matthew 7:15, King James Version). The sermon then suggests that their true nature will be revealed by their acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
