Quintana Roo (company)
Quintana Roo (QR) was the first company to create a triathlon-specific wetsuit over 25 years ago, and then a tri-specific bicycle two years later. The company was founded in 1987 by Dan Empfield of Ironman fame and is currently owned by the American Bicycle Group. Wetsuits The company's flagship product in 1987 was the first wetsuit made specifically for triathlon, designed by Empfield. This new wetsuit was more flexible and more buoyant, giving it swim-specific characteristics that were not found in the diving or surfing wetsuits used by triathletes at that time. In 1990, Quintana Roo discovered and pioneered the use of Yamamoto Rubber #39 in its high-end wetsuits. This new rubber was more buoyant and more flexible than any other rubber that had previously been used in any triathlon wetsuit, and it was followed the next year with Yamamoto SCS (Super-Composite Skin), an outer coating that added even more buoyancy and protected the rubber from fingernail tears.

Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal ...

Redstone (rocket)
The PGM-11 Redstone was the first large American ballistic missile. A short-range ballistic missile (SRBM), it was in active service with the United States Army in West Germany from June 1958 to June 1964 as part of NATO's Cold War defense of Western Europe. It was the first US missile to carry a live nuclear warhead, in the 1958 Pacific Ocean weapons test, Hardtack Teak. The Redstone was a direct descendant of the German V-2 rocket, developed primarily by a team of German rocket engineers brought to the United States after World War II. The design used an upgraded engine from Rocketdyne that allowed the missile to carry the W39 warhead which weighed with its reentry vehicle to a range of about . Redstone's prime contractor was the Chrysler Corporation. The Redstone spawned the Redstone rocket family which holds a number of firsts in the US space program, notably launching the first US astronaut. It was retired by the Army in 1964 and replaced by the solid-fueled MGM-31 Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Yaw Angle
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system.Novi Commentarii academiae scientiarum Petropolitanae 20, 1776, pp. 189–207 (E478PDF/ref> They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in 3-dimensional linear algebra. Alternative forms were later introduced by Peter Guthrie Tait and George H. Bryan intended for use in aeronautics and engineering. Chained rotations equivalence Euler angles can be defined by elemental geometry or by composition of rotations. The geometrical definition demonstrates that three composed ''elemental rotations'' (rotations about the axes of a coordinate system) are always sufficient to reach any target frame. The three elemental rotations may be extrinsic (rotations about the axes ''xyz'' of the original coordinate system, which is assumed to remain motionless), or intrins ...

Drag Coefficient
In fluid dynamics, the drag coefficient (commonly denoted as: c_\mathrm, c_x or c_) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particular surface area. The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure such as an aircraft also includes the effects of interference drag. Definition The drag coefficient c_\mathrm d is defined as c_\mathrm d = \dfrac where: * F_\mathrm d is the drag force, which is by definition the force component in the direction of the flow velo ...

Titanium
Titanium is a chemical element with the Symbol (chemistry), symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Kingdom of Great Britain, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titan (mythology), Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll process, Kroll and Hunter process, Hunter processes. The most common compound, titanium dioxide, is a popular photocatalysis, photocatalyst and is used in the manufacture of white pigments ...

Litespeed
Litespeed is a U.S. bicycle manufacturer founded in 1986 in Ooltewah, Tennessee by David Lynskey. Litespeed makes titanium and carbon fiber frame road racing bicycles and mountain bikes. Titanium bicycle frames are famed for their ride quality. Litespeed, along with triathlon specific bicycle manufacturer Quintana Roo, is a subsidiary of the American Bicycle Group. History David Lynskey's titanium frame building days started in a custom machine shop known as Southeast Machine started by his father William. The shop specialized in exotic metals (mainly titanium). His interest in bicycles began when he took up cycling while recovering from a running injury. He used leftover titanium from a job at Olin Chemical to build the first frame in the early 80's. Frame after frame was made until one was deemed show worthy and taken to the Long Beach bike show in 1987. Thus began the journey that would make Litespeed the go-to authority on titanium bicycles. In 1999, after the death of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
