Green thinking

There is a widening disparity between the air industry's growth and the projected improvements in jetliner fuel efficiency. Pollution from high-flying jets is more damaging to the environment than the same amount released at ground level. Measures to reduce pollution from air travel include carbon offsetting and the development of carbon-neutral fuels. Aircraft manufacturers have developed drag control, a technique to improve efficiency by reducing friction between a plane and the air. The combination of laminar flow control with a specially modified fuselage to reduce a plane's drag is discussed. Designs include the inclusion of a fan at the rear of the plane and strut-braced wings. The initiative Clean Sky has been announced by nine European aircraft companies to develop greener aeronautics systems. The Silent Aircraft Initiative involved the design of an airliner that is much quieter at take-off and landing. The resulting flying wing (blended wing body) was also surprisingly fuel-efficient. The US air force is working with Boeing to develop a flying wing called the X-48B.
