Jet Planes are aircraft with jet engines. Unlike propeller powered planes, jet planes normally fly at altitudes as high as 33,000 to 49,000 feet. At these altitudes, jet engines can achieve maximum efficiency over long distances. The engines in propeller powered planes achieve their maximum efficiency at much lower altitudes.
The first jet plane to incorporate the principles of the jet plane engine was the Coanda -1910. The engine of this jet plane unlike the modern jet plane engine, used a piston engine rather than a turbine to drive its compressor.
The first operational jet plane fighter was the Messerschmitt ME 262. It was the fastest conventional jet plane aircraft of World War II. About the same time, the United Kingdom made up the first operational jet plane fighter squadron in 1944. The imperial Japanese Navy also developed jet plane aircraft in 1945 including the Nakajima Kikka, partially inspired by German designs.
During the Korean War in 1950, United States Air Force was flying an F-80 which intercepted two North Korean MiG-15s near the Yalu River and shot them down in the first jet plane – to – jet plane dogfight in history.
BOAC operated the first commercial jet plane service from London to Johannesburg in 1952 with the de Havilland Comet. The fastest military jet plane remains the retired SR-71 Blackbird. The fastest commercial jet plane remains the retired Tupolev Tu-144.
Modern jet plane aircraft general cruise at speeds of 0.75 to 0.85 Mach, which is to say 75 percent to 85 percent of the speed of sound. The speed of sound is a function of air temperature and pressure, and therefore the speed of a jet plane aircraft is not consistent in terms of miles per hour, but varies with atmospheric conditions. In general, modern jet planes fly at about 420 to 580 mils per hour.
Some other jet plane aircraft would be jumbo jet, jet airliner, commercial jet plane, jet aircraft, Cessna Citation Jet, Gulfstream Jet, Hawker Jet, Beech Jet, Lear Jet plane.
