Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

Belgian Air Component

The Belgian Air Component (Dutch: Luchtcomponent, French: Composante air) is the air arm of the Belgian Armed Forces. The Belgian Air Force was founded in 1909 and is one of the world's first air forces.

The commander is Major General aviator Frederik Vansina, appointed on 23 July 2009.

History

Foundation and early years

The Belgian Air Force was founded in 1909 as a branch of the Belgian Army, carrying the name Compagnie des Ouvriers et Aérostiers.King Albert's interest in the military use of aircraft was the main impetus for its formation. Coincidentally, in the civil aviation sector, Baron Pierre de Caters earned the first civil pilot's brevet that same year. Caters would promptly establish an aviation school. At approximately the same time, the War Ministry followed the French military's example and had pilots earn a civil pilot's brevet before their military one.

In 1910, three Belgian lieutenants earned their pilot's brevets at the school, paying their own fees. Two of the artillery lieutenants were Baudoin de Montens d'Oosterwyck, who earned Brevet No. 19 on 30 September, and Alfred Sarteel, granted No. 23 on 10 November. The third lieutenant, Georges Nelis, was the new force's first aviation candidate, gaining Brevet No. 28 on 21 December. An aircraft was personally purchased for him.

Belgium (ⁱ/ˈbɛldʒəm/; Dutch: België  [ˈbɛlɣijə]; French: Belgique  [bɛlʒik]; German: Belgien  [ˈbɛlɡiən]), officially the Kingdom of Belgium, is a sovereign state in Western Europe. It is a founding member of the European Union and hosts several of the EU's official seats and as well as the headquarters of many major international organizations such as NATO. Belgium covers an area of 30,528 square kilometres (11,787 sq mi) and has a population of about 11 million people.

Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany.

Belgium is a federal constitutional monarchy with a parliamentary system of governance. Its two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region, officially bilingual, is a mostly French-speaking enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia. Belgium's linguistic diversity and related political conflicts are reflected in its political history and complex system of government.

Force

In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.

The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time. If the mass of the object is constant, this law implies that the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object

Related concepts to force include: thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces changes in rotational speed of an object. In an extended body, each part usually applies forces on the adjacent parts; the distribution of such forces through the body is the so-called mechanical stress. Pressure is a simple type of stress. Stress usually causes deformation of solid materials, or flow in fluids.
