Air Breathing Engines Author: Mohsin Rehman Abstract: This paper mentions the history and early attempts at propulsion and the basic principle and theory of propulsion. Different types of air breathing engines like turbojet turbofan ramjet scramjet etc. their basic working principle along with their different working parts and the air planes on which these engines successfully worked are discussed down the path. Progresses made on historical basis, future planning for the betterment of aircraft propulsion industries and their major priorities are the highlighted areas of this research paper. Index terms: horse power, Mach no, oxidizer, stealth technology, thermodynamics. I. Introduction: In aircraft designing, propulsion system is the basic structure. For an aircraft to leave the ground and be in air we want a system which can speedily thrust it into air. Before going after history and detail we have to learn what propulsion basically is. The word is derived from two Latin words: pro means before or forwards and pellere meaning to drive. Propulsion means to push forward or drive an object forward [1]. A propulsion system is a machine that generates thrust in order to push an object forward. Propulsion systems work on newton’s third law of action and reaction. Action is that working fluid is accelerated by the engine and the reaction to this acceleration produces a force on the engine [1]. The first successful free flights by a man-made
