Jet aircraft

Jet aircraft are aircraft with jet engines. Generally, jets fly at heights of 10,000 to 15,000 meters, because they are cheaper to operate at these heights. Jets are not cheap to run at low heights, which is why propeller powered airplanes are commonly used for very short trips.

The first aircraft to incorporate significant principles of the jet engine was the Coanda-1910 (Romania), piloted by its inventor Henri Coanda in 1910. The engine of this aircraft, unlike the modern jet engine, used a piston engine rather than a turbine to drive its compressor. Unfortunately, the aircraft crashed during its first and only demonstration.

The first true, turbine-equipped jetplane was the Heinkel He 178 (Germany), piloted by Erich Warsitz in 1939 (August 27, 1939).

The first jet fighter was the Messerschmitt Me 262, piloted by Fritz Wendel. It was the fastest conventional airplane of WW II (only the rocket-powered Messerschmitt Me 163 Komet was faster). Mass production started in 1944, too late for a decisive impact. About the same time the United Kingdom produced the Gloster Meteor which made up the first operational jet fighter squadron in 1944 and which saw limited action in WWII.

During the Korean War on November 8, 1950, United States Air Force Lt. Russell J. Brown flying in an F-80, intercepted two North Korean MiG-15s near the Yalu River and shot them down in the first jet-to-jet dog fight in history.

Modern jets generally 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 therefore the speed of a jet is not really "constant" in terms of miles per hour, but varies by atmospheric conditions. In general, modern jets fly at about 420 to 580 miles per hour or 680 to 900 km/h.

A new class of jet aircraft that is becoming popular is very light jet (VLJ) which only seats 6 to 8 people and is going to be used by airlines like DayJet.
