According to the concept aircraft developed by NASA, the design of the hybrid wing body will be used, and it may be possible to have a faster speed in travel. NASA and manufacturers have been designing next-generation aircraft that will enable faster, more fuel-efficient aircraft travel around the world. Its design archive reveals some of the conceptual aircraft that may emerge in just a few dozen years. These aircraft are designed with needles, streamlined fuselage and delta wings. According to a report, "The most popular of these designs is the so-called hybrid wing, which is sometimes described as a wing fusion."
In this design, the wing is seamlessly integrated into the aircraft, which makes it very aerodynamic and can greatly reduce fuel consumption and noise emissions. In 2012, NASA successfully tested a hybrid wing X-48C aircraft with a larger internal volume to transport passengers and cargo. The triangular plane design can cut air more effectively. The aircraft has a 21-foot wingspan. Aviation engineers are also working hard to define new standards. They will create new, quieter aircraft.
