Turbo Fan Engines
In a turbofan engine, some of the air instead of going for combustion is bypassed and does not take part in the combustion. This bypassed air is moved around the engine core and produces additional thrust. In today’s engines, the bypass air produces the majority of the engine’s thrust unlike in the turbojet. Most Jets in production today are Turbofan engines. They are less noisy than turbojet engines and more fuel-efficient. This was another milestone in the evolution of the aircraft engine
Leading Edge Aviation Propulsion technology(LEAP) Turbo Fan Engines
This is a high Bypass Turbofan engine produced by CFM international a 50/50 joint venture of American GE Aviation and French Safran engines. This is a major move in the evolution of the aircraft engine. The LEAP is designed to operate at a higher pressure than other turbofans which is why it is more efficient. It uses flexible fan blades. The LEAP has greater use of composite materials and a bypass ratio of 10:11:1, making the compression ratio roughly double the normal for turbo fans. The LEAP is in use on the B737 MAX and Airbus A320neo
As new demands arise in the evolution of the aircraft engine, aircraft engineers have to work overtime to meet these demands. Currently, the inward in all industries is eco-friendly. This means in the present and near future, aircraft will be guided by their ability not to compromise the current climate and worsen the carbon imprints. Sustainability will guide this process. This is part of the evolution of the aircraft engine.
