Traveling by air this holiday season, or any time of year? If so then you'll be in the company of millions who are directly benefiting from the ongoing research performed by NASA's aeronautical innovators now, and in the future. <\/p>\n
During 2012, NASA's Aeronautics Research Mission Directorate continued a wide range of research projects aimed at advancing the science of flight. Among the goals: enhancing safety, designing more fuel efficient jet engines, enabling quieter airplanes and improving air traffic management while also seeking to educate and inspire future generations of aviation experts. <\/p>\n
NASA's \"aeronauts\" even had a hand in helping scientists learn about the Martian atmosphere during Curiosity's nail-biting descent toward the Red Planet in August. <\/p>\n
Here are some highlights from 2012.<\/p>\n
Developing Technology NASA worked closely with Boeing in 2012 to fly the X-48C Blended Wing Body research aircraft, a sub-scale, remotely piloted vehicle intended to test new aircraft designs that forgo the conventional tube-and-wing airplane look in favor of one that blends the vehicle's wing and body into a smoothly contoured shape. Researchers believe this design could someday reduce fuel consumption by nearly 60 percent, noise by 70 percent, and emissions by 80 percent. Read More <\/p>\n
Meanwhile, working with the California Polytechnic State University in San Luis Obispo, Calif., NASA researchers tested a 2,500-pound aluminum and steel model of an airplane that looked like its wings were put on upside down, with its jet engines installed on top of the wings. The unusual-looking model was designed to test ways for an aircraft to make short take offs and landings, fly fuel efficiently at cruise altitude, and do so more quietly than today's modern airliners. <\/p>\n
The project was named for famed aviatrix Amelia Earhart and called AMELIA, short for Advanced Model for Extreme Lift and Improved Aeroacoustics. Like the X-48C, information gleaned from AMELIA will lead to future aircraft designs that dramatically reduce fuel use, noise and emissions. Read More <\/p>\n
Quieter Supersonic Flight NASA is continuing to learn more about how sound waves created by supersonic aircraft move through the atmosphere, all with an eye towards designing aircraft that generate sonic booms you can barely hear - or can't hear at all - on the ground below. This work could open a whole new segment of the economy for commercial aviation by making supersonic flight over land acceptable. <\/p>\n
Following a series of research flights last year, NASA engineers in 2012 poured over information they gathered from residents near Edwards Air Force Base in California to see how well they did in generating sonic booms with NASA's F\/A-18 jet that could barely be heard on the ground. The Waveforms and Sonic boom Perception and Response, or WSPR, project gathered data from a select group of more than 100 volunteers. A final report on the study is due soon. <\/p>\n
Another phase of this research began in 2012 with the Farfield Investigation of No Boom Threshold, or FaINT. Using NASA's F\/A-18 supersonic jet, project researchers will try to better understand what's happening at the very edge of the sonic boom, or just beyond. Read More <\/p>\n
