NASA Ames 2016 Summer Series. Strong, ultra-lightweight materials are expected to play a key role in the design of future aircraft and space vehicles. Dr. Kenneth Cheung is developing cellular composite building blocks, or digital materials, to create transformable aerostructures. Lower structural mass leads to improved performance, maneuverability, efficiency, range and payload capacity. In his presentation, Dr. Cheung discusses the implications of the digital materials and morphing structures.
