According to NASA, this Solid State Aircraft will be “able to soar for long periods of time and utilize flapping to regain lost altitude.” Continue reading for a video — courtesy of EcoGeek.
During Phase I work on this concept, analysis was performed on the glide duration, flap duration, wing length, and wing motion of travel. It was determined that a versatile, robust, advanced aeronautical architecture can be produced taking into account these parameters. This architecture would enable flight over a broad flight envelope comprised of a range of latitudes and times of the year on Earth, Venus, and Mars
