Air travelling

Even though airlines are taking steps to green the air travel industry, the real culprit here is still the output of carbon-emitting fossil fuels that aircrafts rely on for energy.Aircraft manufacturers are demonstrating a commitment to solving this problem.Air travelling companies as Boeing and Airbus are interested in working with British carrier easyJet to produce a new design that has garnered the nickname "ecoJet." This design promotes maximum fuel-efficiency by minimal aerodynamic resistance and is similar to projects that Boeing and Airbus envision as the future of mass air travel.
Aerospace engineers are examining various technological innovations to accomplish these cleaner, greener flights:

• Laminar flow control. The air that immediately surrounds the body of an airplane when it is flying suffers a great deal of disturbance. This increases friction between the plane and the surrounding air, which in turn leads to higher fuel consumption. The aim is to reduce the friction and thereby lessen the plane’s drag.

• Uses of composite materials. Aerospace engineers are now looking at using composite materials to build aircraft. The logic is that using such materials will make for a lighter, and therefore more fuel efficient aircraft.
