World War II was the first war in which jet aircraft participated in combat with examples being used on both sides of the conflict during the latter stages of the war. The first successful jet aircraft, the Heinkel He 178, flew only five days before the war started on 1 September 1939. [1]
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound .
The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines and the social and cultural changes fostered by commercial jet travel. Jet airliners were able to fly higher, faster, and farther than older piston ‑powered propliners , making transcontinental and intercontinental travel ...
The areas of the world covered by commercial air routes in 1925. Sometimes dubbed the Golden Age of Aviation, [1] the period in the history of aviation between the end of World War I (1918) and the beginning of World War II (1939) was characterised by a progressive change from the slow wood-and-fabric biplanes of World War I to fast, streamlined metal monoplanes, creating a revolution in both ...
The early marks of Spitfire and Hurricane had machine guns that were, however, of the .30 calibre (7.62mm) class, with less hitting power than heavier calibre weapons firing non-explosive bullets - the Germans' MG 131 machine gun, the Japanese Ho-103 machine gun, the Soviets' Berezin UB and particularly the "light-barrel" AN/M2 version of the ...
The list of aircraft of World War II includes all of the aircraft used by countries which were at war during World War II from the period between when the country joined the war and the time the country withdrew from it, or when the war ended.
Almost as soon as they were invented, aeroplanes were used for military purposes. The first country to use them for military purposes was Italy, whose aircraft made reconnaissance, bombing and artillery correction flights in Libya during the Italian-Turkish war (September 1911 – October 1912). This war also saw Ottoman soldiers shoot down a ...
This article outlines the important developments in the history of the development of the air-breathing (duct) jet engine.Although the most common type, the gas turbine powered jet engine, was certainly a 20th-century invention, many of the needed advances in theory and technology leading to this invention were made well before this time.
