The Evolution Of Jet Engines :: essays research papers

The Evolution of Jet Engines     The kelvin railway locomotive is a complex propulsion device which draws in snap bymeans of an intake, compresses it, heats it by means of an internal combustionrailway locomotive, which when expelled it turns a turbine to spring up thrust, resulting in a pierce sufficient enough to propell the aircraft in the inverse direction(Morgan 67). When the jet railway locomotive was thought of back in the 1920s the humansnever thought it would become a reality, scarce by 1941 the graduation exercise successful jetflight was fl cause in England. Since then the types of engines have changed, butthe basic principals have remained the same.     In 1921 thoughts of a jet engine were base upon adaptations of pistonengines and were usually very heavy and complicated. These thoughts wererefined in the 1930s when the turbine engine design lead to the patent of the turbofan engine by Sir rude Whittle of Great Britian. It was Sir Whittlesdesign that lead Great Britian into the jet sequence with the first successful flight.At the same time, the Germans were designing there own jet engine and aircraftwhich would be one of the factors that kept Germany alive in World War II. Withtechnological advances by the allies a prototype turbojet known as the "HeinkelHe 178" came into a few operable squadrons in the German, British, and theAmerican air forces towards the end of World War II. These jets eventually helpedthe allies to win the war against the axis powers(Smith 23-27).     A recentlyr phylogeny in the jet industry was the overcoming of the vowelizebarrier and establishing normal trading operations up to and beyond twice the speed ofsound. Also air force bombers and transports were able to reach and cruise atsupersonic speeds(Silverstein 56-70). In the late 1950s civil transcontinentaljet services started with the Comet 4 and the Boeing 707. In the mid(prenominal) 1 960s allmajor jet manufacturing companies revised their present engines with newmaterials much(prenominal) as aircraft aluminium which made them lighter and turbine changesso they could compress the air at a much higher pressure so the engine canproduce much more thrust.The first supersonic airliner is the touch turbojetConcorde which flies at over twice the speed of sound which was brought intoregular service in 1976(Smith 27-30). The one company that dominates theprivate jet industry is Bombardier which makes the Learjet turbofans, they havean approximate cruising distance of 1880 nautical miles(Jennings 103).In the future, turbojet engines will continue to further develop due to thetechnological advances made. As in graphite composite wings, thermoplastic
