Emerging Materials For Revolutionary Aerospace Vehicle Structures and Propulsion Systems

摘要

The NASA Strategic Plan identifies the long-term goal of providing safe and affordable space access, orbital transfer, and interplanetary transportation capabilities to enable scientific research, human and robotic exploration, and the commercial development of space. Numerous scientific and engineering breakthroughs will be required to develop the technology required to achieve this goal. Critical technologies include advanced vehicle primary and secondary structure, radiation protection, propulsion and power systems, fuel storage, electronics and devices, sensors and science instruments, and medical diagnostics and treatment. Advanced materials with revolutionary new capabilities are an essential element of each of these technologies. A survey of emerging materials with applications to aerospace vehicle structures and propulsion systems was conducted to assist in long-term agency mission planning. The comprehensive survey identified materials already under development that could be available in five to ten years and those that are still in the early research phase and may not be available for another 20 to 30 years. The survey also includes the results of several systems analysis studies that highlight the enormous potential of one revolutionary new material, carbon nanotubes.
