BREAKING THE SOUND BARRIER WITH AIR BREATHING JET ENGINE

This paper represents a study on air breathing jet engines. Jet engines are similar to the gas turbine, jet engines produces thrust by jet propulsion according to the newton’s law of motion. Gas turbines are used for aircraft propulsion due to favourable power to weight ratio. In this paper we know about the working, component design, material used for the construction of jet engine. We learn about the factors responsible for the production of noise in the jet engine and solution through which we reduce the level of noise and know about the stress and temperature faced by the jet engine during its working. Materials used for the production of parts of the jet engine such as super alloys, super alloys are those material which can withstand at a very high temperature without deformation of the shape like nickel based super alloy and study about those smart structure or material which possess the ability to change shape during flight and came to its original shape and size .In this paper we widely discuss about turbojet engine and turbofan jet engines and the comparison shown which gives us idea about the difference between the construction and working of rockets and jet engines
