Project Nike

Project Nike, (Greek: Νίκη, "Victory", pronounced [nǐːkɛː]), was a U.S. Army project, proposed in May 1945 by Bell Laboratories, to develop a line-of-sight anti-aircraft missile system. The project delivered the United States' first operational anti-aircraft missile system, the Nike Ajax, in 1953. A great number of the technologies and rocket systems used for developing the Nike Ajax were re-used for a number of functions, many of which were given the "Nike" name (after Nike, the goddess of victory from Greek mythology). The missile's first-stage solid rocket booster became the basis for many types of rocket including the Nike Hercules missile and NASA's Nike Smoke rocket, used for upper-atmosphere research.

History

Project Nike began during 1944 when the War Department demanded a new air defense system to combat the new jet aircraft, as existing gun-based systems proved largely incapable of dealing with the speeds and altitudes at which jet aircraft operated. Two proposals were accepted. Bell Laboratories offered Project Nike. A much longer-ranged collision-course system was developed by General Electric, named Project Thumper, eventually delivering the BOMARC missile.

Missile

In modern usage, a missile is a self-propelled precision-guided munition system, as opposed to an unguided self-propelled munition, referred to as a rocket (although these too can also be guided). Missiles have four system components: targeting and/or missile guidance, flight system, engine, and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. All known existing missiles are designed to be propelled during powered flight by chemical reactions inside a rocket engine, jet engine, or other type of engine. Non-self-propelled airborne explosive devices are generally referred to as shells and usually have a shorter range than missiles.

In ordinary British-English usage predating guided weapons, a missile is "any thrown object", such as objects thrown at players by rowdy spectators at a sporting event.

Missile (1987 film)

Missile is a 1987 American documentary film by Frederick Wiseman. It chronicles the 14 week training course for the men and women of the United States Air Force who are charged with manning the ICBM silos in remote places like Minot AFB and Whiteman AFB. The film shows discussions of the ethics of nuclear war, shows scenes from the daily lives of trainees, and shows demonstrations of training exercises such as counterterrorism, the launching of nuclear missiles, the command and control process, and basic military training. Most scenes in the film are of classroom training, interspersed with exercises in training facilities. The film includes a scene of an Air Force church service memorial for the astronauts killed in the Space Shuttle Challenger disaster.

In the typical style of Wiseman's films, the documentary is unadorned by commentary, narration, or music.

Flight dynamics

Flight dynamics is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle influence its speed and attitude with respect to time.

In fixed-wing aircraft, the changing orientation of the vehicle with respect to the local air flow is represented by two critical parameters, angle of attack ("alpha") and angle of sideslip ("beta"). These angles describe the vector direction of airspeed, important because it is the principal source of modulations in the aerodynamic forces and moments applied to the aircraft.

Spacecraft flight dynamics involve three forces: propulsive (rocket engine), gravitational, and lift and drag (when traveling through the earths or any other celestial atmosphere). Because aerodynamic forces involved with spacecraft flight are very small, this leaves gravity as the dominant force.

Aircraft and spacecraft share a critical interest in their orientation with respect to the earth horizon and heading, and this is represented by another set of angles, "yaw," "pitch" and "roll" which angles match their colloquial meaning, but also have formal definition as an Euler sequence. These angles are the product of the rotational equations of motion, where orientation responds to torque, just as the velocity of a vehicle responds to forces. For all flight vehicles, these two sets of dynamics, rotational and translational, operate simultaneously and in a coupled fashion to evolve the vehicle's state (orientation and velocity) trajectory.

List auf Sylt

List auf Sylt (known as List until 31 December 2008) is the northernmost municipality in Germany, located on the North Sea island of Sylt close to Denmark in the district of Nordfriesland in the state of Schleswig-Holstein.

Etymology

List derived from the Middle Low German Liste (ledge, bar or edge).

History

List was originally a Danish settlement. It was first mentioned in 1292 (Lystum). The original village was destroyed by the great flood of 1364. The settlement was rebuilt further east from the previous location. In the mid-15th century, a church named St. Jürgen was mentioned. In a treaty of 1460, Schleswig and Holstein were linked to the Danish crown, but List remained part of the royal enclaves, small areas of the Kingdom of Denmark situated within the Duchy of Schleswig, but directly controlled by the Danish king.

From the 16th century, the people of List mostly made a living from Oyster farming, raising sheep and collecting and selling gull eggs. At the time, List was an important protective anchorage. In 1644, a Swedish-Dutch fleet of 26 ships commanded by Admiral Thijssen was attacked in the Lister Tief and defeated by Danish ships commanded by king Christian IV of Denmark. The anchorage north of today's town was named Königshafen to honour this event.

Jousting

Jousting is a martial game or hastilude between two horsemen wielding lances with a blunted tips, often as part of a tournament. The primary aim was to replicate a clash of heavy cavalry, with each opponent endeavoring to strike the opponent while riding towards him at high speed, if possible breaking the lance on the opponent's shield or jousting armour, or unhorsing him. The joust became an iconic characteristic of the knight in Romantic medievalism. Jousting matches were notably depicted in Ivanhoe(a novel).

The term is derived from Old French joster, ultimately from a Late Latin iuxtare "to approach, to meet". The word was loaned into Middle English around 1300, when jousting was a very popular sport among the Anglo-Norman knighthood. The synonym tilt dates ca. 1510.

Jousting is based on the military use of the lance by heavy cavalry. It transformed into a specialised sport during the Late Middle Ages, and remained popular with the nobility both in England and Germany throughout the whole of the 16th century (while in France, it was discontinued after the death of King Henry II in an accident in 1559). In England, jousting was the highlight of the Accession Day tilts of Elizabeth I and James I, and also was part of the festivities at the marriage of Charles I.
