Pye Wacket
Pye Wacket was the codename for an experimental Lens (geometry), lenticular-form air-to-air missile developed by the Convair Division of the General Dynamics Corporation in 1957. Intended as a defensive missile for the B-70 Valkyrie Mach 3 bomber, the program saw extensive wind-tunnel testing and seemed promising; however, the cancellation of the B-70 removed the requirement for the missile, and the project was cancelled. Genesis Project "Pye Wacket", officially known as the Lenticular Defense Missile (LDM) Program and by the project number WS-740A, was instituted in 1958 in response to a US Air Force request for a Defensive Anti-Missile System (DAMS) to protect the proposed B-70 Valkyrie strategic bomber from high-speed, high-altitude surface-to-air missiles (SAMs) and interceptor aircraft.Parsch 2005 The extreme speed and operating altitude of the Valkyrie was considered sufficient protection against Soviet interceptors of the time. However it was anticipated that future aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strategic Bomber
A strategic bomber is a medium- to long-range penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombers, penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after strategic bombing was widely employed, and atomic bombs were first used in combat during World War II. Nuclear strike missions (i.e., delivering nuclear-armed missiles or bombs) can pote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Sled Launch
A rocket sled launch, also known as ground-based launch assist, catapult launch assist, and sky-ramp launch, is a proposed method for launching space vehicles. With this concept the launch vehicle is supported by an eastward pointing rail or maglev track that goes up the side of a mountain while an externally applied force is used to accelerate the launch vehicle to a given velocity. Using an externally applied force for the initial acceleration reduces the propellant the launch vehicle needs to carry to reach orbit. This allows the launch vehicle to carry a larger payload and reduces the cost of getting to orbit. When the amount of velocity added to the launch vehicle by the ground accelerator becomes great enough, single-stage-to-orbit flight with a reusable launch vehicle becomes possible. For hypersonic research in general, tracks at Holloman Air Force Base have tested, as of 2011, small rocket sleds moving at up to (; Mach 8.5). Effectively a ''sky ramp'' would make th ...

Thiokol M58
Thiokol (variously Thiokol Chemical Corporation(/Company), Morton Thiokol Inc., Cordant Technologies Inc., Thiokol Propulsion, AIC Group, ATK Thiokol, ATK Launch Systems Group; finally Orbital ATK before becoming part of Northrop Grumman) was an American corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. Its name is a portmanteau of the Greek words for sulfur (θεῖον ''"theion"'') and glue (κόλλα ''"kolla"''), an allusion to the company's initial product, Thiokol polymer. The Thiokol Chemical Company was founded in 1929. Its initial business was a range of synthetic rubber and polymer sealants. Thiokol was a major supplier of liquid polymer sealants during World War II. When scientists at the Jet Propulsion Laboratory discovered that Thiokol's polymers made ideal binders for solid rocket fuels, Thiokol moved into the new field, opening laboratories at Elkton, Maryland, and later production facilities ...

Magnesium Alloy
Magnesium alloys are mixtures of magnesium (the lightest structural metal) with other metals (called an alloy), often aluminium, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys. Plastic deformation of the hexagonal lattice is more complicated than in cubic latticed metals like aluminium, copper and steel; therefore, magnesium alloys are typically used as cast alloys, but research of wrought alloys has been more extensive since 2003. Cast magnesium alloys are used for many components of modern automobiles and have been used in some high-performance vehicles; die-cast magnesium is also used for camera bodies and components in lenses. Practically, all the commercial magnesium alloys manufactured in the United States contain aluminium (3 to 13 percent) and manganese (0.1 to 0.4 percent). Many also contain zinc (0.5 to 3 percent) and some are hardenable by he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pomona, California
Pomona is a city in Los Angeles County, California. Pomona is located in the Pomona Valley, between the Inland Empire and the San Gabriel Valley. At the 2020 census, the city's population was 151,713. The main campus of California State Polytechnic University, Pomona, also known as Cal Poly Pomona, lies partially within Pomona's city limits, with the rest being located in the neigboring unincorporated community of Ramona. History Beginnings to 1880 The area was originally occupied by the Tongva Native Americans. The city is named after Pomona, the ancient Roman goddess of fruit. For horticulturist Solomon Gates, "Pomona" was the winning entry in a contest to name the city in 1875, before anyone had ever planted a fruit tree there.A Brief History of Pomona The city was first settled by Ricardo Véjar an ...

Angles Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuselage as the reference line (and also as the longitudinal axis).

Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag-shape ...

May Day Parade
May Day is a European festival of ancient origins marking the beginning of summer, usually celebrated on 1 May, around halfway between the spring equinox and summer solstice. Festivities may also be held the night before, known as May Eve. Traditions often include gathering wildflowers and green branches, weaving floral garlands, crowning a May Queen (sometimes with a male companion), and setting up a Maypole, May Tree or May Bush, around which people dance. Bonfires are also part of the festival in some regions. Regional varieties and related traditions include Walpurgis Night in central and northern Europe, the Gaelic festival Beltane, the Welsh festival Calan Mai, and May devotions to the Blessed Virgin Mary. It has also been associated with the ancient Roman festival Floralia. In 1889, 1 May was chosen as the date for International Workers' Day by the Second International, to commemorate the Haymarket affair in Chicago and the struggle for an eight-hour working day. ...
