Abstract:
Our paper explains that how the modification in shape of an aircraft becomes more fuel efficient, quieter and capable of significantly longer distance travel. NASA’s Aeronautics Research Mission Directorate and Boeing are funding the X-48 technology demonstration research effort with a blended wing body design,which is essentially a cross between a flying-wing design and a conventional plane, merging the aircraft’s wing and body into one structure. The biggest difference between the X-48C and present day aircraft is its revolutionary triangular look, a Blended Wing Body design (BWB). The design offers potential customers long-term fuel efficiency, more fuel capacity, and noise reduction benefits. The aircraft’s profile allows air to pass over it more efficiently compared to present day planes, allowing for lower drag and better lift, which the X-48 team expects will equate to a 20-30% improvement in fuel consumption when the final full-scale version of the X-48 is complete. BWB aircraft could be controlled at low-speeds just as effectively as any present day conventional aircraft.In addition to this,noise shielding designs were applied to the airframe for noice-reduction. The engines are above aft center to make sound bounce up or to the side,rather than down towards the ground. The wingtip winglets were relocated inboard next to the engines, and the aft deck was extended two feet to the rear.Flight control system software modifications were developed, including flight control limiters to keep the aircraft flying within a safe flight envelope. With a wingspan of just over 20 feet and weighing in at about 500 pounds, the X-48C can reach an altitude of 10,000 feet and fly for 35 minutes at an estimated top speed of 140 miles per hour. The X-48 could be used for a wide range of military and civilian applications like a bomber, a tanker, a transport,aerial refueller, a command-and-control plane, or even a commercial jetliner.Due to this design no windows...
