Gun harmonisationIn aerial gunnery, gun harmonisation, convergence pattern, convergence zone, convergence point or bore-sight point refers to the aiming of fixed guns or cannon carried in the wings of a fighter aircraft. The wing guns in fighters were typically not bore-sighted to point straight ahead; instead they were aimed slightly inward so that the projectiles met at one or more areas several hundred yards or metres in front of the fighter's nose.
Manfred von RichthofenManfred Albrecht Freiherr von Richthofen (ˈmanfreːt fɔn ˈʁɪçthoːfn̩; 2 May 1892 – 21 April 1918), known in English as Baron von Richthofen or the Red Baron, was a fighter pilot with the German Air Force during World War I. He is considered the ace-of-aces of the war, being officially credited with 80 air combat victories. Originally a cavalryman, Richthofen transferred to the Air Service in 1915, becoming one of the first members of fighter squadron Jagdstaffel 2 in 1916.
Air supremacyAerial supremacy (also known as air superiority) is the degree to which a side in a conflict holds control of air power over opposing forces. There are levels of control of the air in aerial warfare. Control of the air is the aerial equivalent of command of the sea. Air power has increasingly become a powerful element of military campaigns; military planners view having an environment of at least air superiority as a necessity.
Fighter aircraftFighter aircraft (early on also pursuit aircraft) are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft.
Synchronization gearA synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate.
Foster mountingThe Foster mounting was a device fitted to some fighter aircraft of the Royal Flying Corps during the First World War. It was designed to enable a machine gun (in practice, a Lewis Gun) to fire over, rather than through the arc of the spinning propeller. It took several forms when applied to different aircraft types, but all shared the feature of a quadrant shaped I-beam rail on which the gun could slide back and down in one movement.
Basic fighter maneuversBasic fighter maneuvers (BFM) are tactical movements performed by fighter aircraft during air combat maneuvering (ACM, also called dogfighting), to gain a positional advantage over the opponent. BFM combines the fundamentals of aerodynamic flight and the geometry of pursuit, with the physics of managing the aircraft's energy-to-mass ratio, called its specific energy. Maneuvers are used to gain a better angular position in relation to the opponent.
Yalu RiverThe Yalu River (), known by Koreans as the Amrok River or Amnok River, is a river on the border between China and North Korea. Together with the Tumen River to its east, and a small portion of Paektu Mountain, the Yalu forms the border between China and North Korea. Its valley became the scene of several military conflicts in the past centuries. The Korean name Amnok (압록,鴨綠) is most likely derived from ancient Koreanic language of Goguryeo.
Indian Air ForceThe Indian Air Force (IAF) is the air arm of the Indian Armed Forces. Its primary mission is to secure Indian airspace and to conduct aerial warfare during armed conflicts. It was officially established on 8 October 1932 as an auxiliary air force of the British Empire which honoured India's aviation service during World War II with the prefix Royal. After India gained independence from United Kingdom in 1947, the name Royal Indian Air Force was kept and served in the name of the Dominion of India.
JagdstaffelA Jagdstaffel (plural Jagdstaffeln, abbreviated to Jasta) was a fighter Staffel (squadron) of the German Imperial Luftstreitkräfte during World War I. Before April 1916, Die Fliegertruppen des deutschen Kaiserreiches, which had been established in 1912 as the aviation service of the Imperial German Army, was largely organised in small general purpose units (Feldfliegerabteilungen, FFA Field Flyer Detachments). The first specialist bombing and close support units began forming during 1915.
