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.

Chilean Air Force

The Chilean Air Force (Spanish: Fuerza Aérea de Chile, FACh) is the air force of Chile, a branch of the Chilean military.

History

The first step towards the current FACh was taken by Teniente Coronel Pedro Pablo Dartnell, when he founded the Servicio de Aviación Militar de Chile (Military Aviation Service of Chile) on December 20, 1910, being trained as a pilot in France. Although a school was included, the first officers were sent to France for their training as well. One of them, Captain Manuel Ávalos Prado, took command over the Chilean military aviation school that was officially instated 11 February 1913, and remained in command until 1915. The Escuela de Aviación Militar (Military Aviation School) was named in honor of him in 1944, and still carries that name today.

In those early years many aviation milestones were achieved; conquering the height of the Andes was one of the main targets as well as long distance flights. Typical aircraft of that era were Avro 504, Bleriot XI, Bristol M.1C, DH.9, and SE5a. In the following decade, the (Airmail Line of Chile) Línea Aeropostal de Chile was created on 5 March 1929 as a branch of the military aviation. This postal airline later developed into the airline Línea Aérea Nacional (National Airline) that is still the leading airline in Chile today. Shortly afterwards, on 21 March 1930, the existing aviation elements of the army and navy were amalgamated into a dedicated department: the Subsecretaria de Aviación (Department of the Air Force) effectively creating the current independent Air Force. It was initially named Fuerza Aérea Nacional (National Air Force). The international airport of Chile carries the name of Lan's founding father and first commander of the air force, Air Commodore Arturo Merino Benítez. Its baptism of fire was in the 1931 sailors' rebellion in Coquimbo, where Air Force attack aircraft and bombers and 2 transport planes converted into bombers contributed to its failure.

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.
